Full textThe constant increasing of fishing activities and marine traffic have made the monitoring and the classification of the ships activities an open challenge in marine scenario. Continued exploitation of fish resources has drastically reduced the abundance of these resources, with negative consequences on the fisheries sector itself. Over the years, some tools have been introduced, but initially they were only used to improve the safety of maritime traffic. The necessity of solving the problem of the monitoring and the classification of the ships activities in the new era of Artificial Intelligence (AI) leads to the development and to the implementation of new methods in Machine Learning (ML). In particular, the application of AI in this context defines a new concept called Precision Fishing. The work of this thesis has been developed in collaboration with “Istituto per le Risorse Biologiche e le Biotecnologie Marine” of the CNR (CNR-IRBIM). The aim of this research is to increase fisheries control by analysing Automatic Identification System (AIS) data and integrating them with additional data such as “Synthetic Aperture RADAR” (SAR) images. The objectives of this thesis regarded (i) the identification and (ii) the classification of fishing activities; (iii) the identification of illegal, unreported and unregulated (IUU) fishing activities through AI approaches. In the first topic, it is described an algorithm able to identify every single fishing session, meaning everything that happens from when the ship leaves the port of departure to the port of destination. In order to obtain this result, the first operation carried out is the filtering of outliers (on-land or erroneous AIS data), which has been achieved through a process of interpolation. The algorithm developed uses a rule set to identify each fishing session. Another innovative aspect of the algorithm compared to the state of the art is that it reconstructs incomplete fishing sessions, meaning those that do not have a temporally uniform distribution of AIS data. The reliability of the proposed method was evaluated on a dataset validated by experts in the field, and the results obtained showed that the effectiveness of the method outperformed the state of the art. In the second research topic, it is proposed a set of algorithms based on AI technologies in order to classify fishing activities. In detail, several classification algorithms are implemented using different Machine Learning and Deep Learning techniques. The innovation of this thesis over the state of the art is the design and the development of AI algorithms to support decision makers in the Precision Fishing field using AIS and satellite data. The reliability of the proposed methods was investigated using datasets validated by experts in the field and by studying the behaviour of ships over the years. The results obtained are better than the state of the art and this makes some of the proposed algorithms candidates to be considered as gold standard. In the third topic, it is presented an algorithm for the identification of IUU fishing activities. In this case the use of the AIS system alone is insufficient because in most cases, when the ship is engaged in this type of activity, the on-board systems are switched off so that the vessel cannot be located. The solution proposed is to integrate AIS data with SAR satellite images in order to recover the missing information, and thanks to the classification of fishing activities algorithm all those that are considered suspicious are detected. The proposed method has been validated by experts in the field and by the analysis of logbooks integrating knowledge of fishing systems.

Full textThe Magnuson-Stevens Fishery Conservation and Management Act (MSA; Magnuson-Stevens Fishery Conservation and Management Act. 2014. (16 U.S.C. 1801–1891(d)) mandates that fisheries management councils in the United States prevent adverse, or “more than minimal and not temporary”, fishing effects to essential fish habitat (EFH) to the extent practicable. Councils were left to decide what effects qualified as “minimal” and “temporary”. The lack of explicit definition in the MSA and its accompanying Final Rule has resulted in inconsistent habitat management throughout the country. The EFH mandate was written under an implicit assumption that councils have the scientific information necessary to effectively manage EFH. Basic information is lacking, such as what type of habitat occurs where, and how fishing effects habitat features. Chapter 1 briefly reviews the history of EFH regulation, the consequences of regulatory ambiguities and information gaps, and highlights that high latitude fisheries management can be disproportionately affected by climate variability. Thus, requiring investment in baseline habitat assessment and monitoring and renewed focus on under developed areas of research e.g. Fishing effects and gear-habitat interactions.
Councils have attempting to quantitatively describe fishing effects to EFH through the use of mathematical models. The most recent of which, the Fishing Effects (FE) Model, was used in the North Pacific Fisheries Management Council 2015 EFH Review cycle. The FE Model uses discrete time steps (monthly) and spatially explicit fishing effort and sediment data to calculate an estimated habitat disturbance. The FE Model is calculated in two-dimensions and implicitly assumes that if fishing gear does not contact the seabed, then there is no gear-habitat interaction. Some features stand taller than raised gear (e.g. sea whips, Halipteris willemoesi, in the North Pacific can up to 2m tall) and may interact with fishing gear. The FE Model in two-dimensions does not account for this potential interaction and cannot effectively simulate gear modifications. Chapter 2 proposes an adapted version of the FE Model that accounts for the vertical interactions through the use of discrete height bins. To accurately estimate interactions on and above the seabed, fishing gear has to be recharacterized. To demonstrate this the Bering Sea flatfish trawl was recharacterized by calculating how much of the nominal gear width is present in each height bin. A detailed methodology is provided to allow this method to be applied to any fishing gear. The adapted FE Model can be used to simulate gear modifications, as is shown by simulating two modifications of the flatfish trawl. This chapter will inform the 2020 EFH Review cycle as the FE Model is improved.

Full textMany fisheries have significant challenges related to sustainable development, such as overexploitation and overcapacity in the fishing fleet. Overcapacity leads to increased pressure on fish resources, reduced profitability, and environmental problems such as greenhouse gas (GHG) emissions and acidification fromfuel consumption. Sustainable management of the fish resources is an important objective in Norway, but overcapacity is a problem in several Norwegian fleet segments. Important issues in this respect are whether the traditional management models are able to deal with the capacity development, and whether the role of technology as a relevant discipline in fisheries management is underestimated.
The objective of this work has been to integrate a technological perspective into fisheries management in order to improve sustainability in the fishing fleet. The thesis work has been limited to the Norwegian fisheries in Norwegian territorialwaters. Since the main problems addressed in this thesis are sustainability and overcapacity, the system boundaries are limited to the fishing fleet. This means that the marine ecosystem in where the fishing vessels are interacting, is outside the thesis’ boundaries.
The main contributions of this thesis are:
• Development of a methodological framework that structures fisheries management decision-making, with main emphasis on improved sustainability in the fishing fleet.
• Clarification of the concept of sustainability in the Norwegian fishing fleet.
• Classification of attributes characterizing sustainability, and a performance evaluation of the different vessel groups in the cod-fishing fleet.
• Comparison of two cod-production systems, with focus on sustainability.
• Suggestions for how fisheries management can evaluate sustainability on a regular basis.
• Improved foundation for further research about sustainability in the fisheries. A lot of literature is collected and synthesized.
The framework developed is based on the systems engineering process. The nature of sustainability requires a systems perspective. There are different system analysis methods, but from a technological perspective, dealing with multidisciplinary tasks, systems engineering has been selected as the most feasible process. It has a strong focus on stakeholder needs and requirements, and it facilitates frequent evaluations of sustainability, which is important in order to assess management efficiency and goal achievement.
Problems regarding sustainability in the fisheries are not only caused by technological development, but have organizational challenges as well. However, in this thesis the focus is within the technological perspective. Systems engineering is not applied as an attempt to change the structure of fisheries management, but as means of suggesting a decision-making process that improves sustainability in the fishing fleet.
Fisheries management involves decision-making in situations often characterized by high risks and uncertainties, and it may be difficult to predict the outcomes of the decisions, for example, regarding sustainability in the fishing fleet. A number of tools that are available to support decision-making have been discussed and used in the thesis, such as cost-benefit analysis, risk acceptance criteria, life cycle cost (LCC), the Analytic Hierarchy Process (AHP), and Quality Function Deployment (QFD). Nevertheless, these tools do not provide “correct” answers; they have limitations, they are based on a number of assumptions, and their uses are based on scientific knowledge as well as value judgments involving political, strategic, and ethical issues. This means that these methods leave the decision-makers to apply decision processes outside the practical applications of the analyses, to which the framework offers guiding principles and structure.
The main outcome of using systems engineering principles in fisheries management, is that the framework offers a broader analytical perspective to fisheries management and sustainability, which acknowledge that sustainability cannot be distinguished fromthe context. Today, most input to fisheries management come from biology and economy, such as stock assessments and profitability analyses. In systems engineering, information from different scientific disciplines, for example, biology, social sciences, economy, and technology, are necessary input to the analyses and decision processes, because fisheriesmanagement is much more than bio-economics. Application of the systems engineering process in fisheries management, and the inclusion of technology, introduce new perspectives, new disciplines, and new stakeholders into the decision-making process in the fisheries.
Based on the framework developed in the thesis, the sustainability performance of the cod-fishing fleet has been evaluated. Sustainability in the fishing fleet may be characterized by seven attributes; accident risk, employment, profitability, quality, catch capacity, bycatch/selection, andGHGemissions/acidification. Indicators have been identified in order to measure the system performance within the attributes. The evaluation shows that there are differences in the performance of the vessel groups. These differences pose a major challenge to fisheries management in their decision-making regarding sustainability in the fleet. The smallest vessels have the lowest fuel consumption (kg fuel/kg fish), but they have a very high accident risk (FAR). The evaluation of cod fishing vs. cod farming shows that the potential growth in the cod farming industry may cause changes in the management system of the cod fisheries, such as a possible shift from the IVQ-systemof today to an ITQ-system.
The Norwegian fisheries management lacks frequent evaluations of its policies, and the information and data available about the fisheries are fragmented. Sustainability should be evaluated on a regular basis by use of performance indicators to determine if sustainability increases or decreases. For simplicity, the indicators could be aggregated into a sustainability index showing the overall system performance. Aggregation implies simplification and weighting of the indicators, which means that such an index should be used with care. Sustainability implies a long term perspective when taking decisions, because future generations will be affected. The performance evaluations can give indications of trends, which means that the results can be used to predict consequences in the future, based on the current development.

ENGLISH ABSTRACT: The trawler industry is on the brink of proserity. This progress will result in both the trawler industry and the state amending their policy formulation to adapt to changing circumstances. The government will, for instance, have to consider subsidising the building of boats and the establishment of infrastructure, which is becoming increasingly expensive, and is already being done abroad. On the other hand, planning and organisation of trawler industries will have to be done in close consultation with the government, who is in fact responsible for fish sources. This will result in an enormous responsibility for the government, who will have to improve research on fish resources and availability of fish species. This information is of the utmost importance to trawler industries that have to plan for future production and sales. The progress of trawler industries is not just influenced by the government but also by their own internal planning. Future development will definitely require more capital outlay from industries in the form of modernized catching and processing equipment. In the present-day highly competitive and rapidly changing environment it is difficult to generate funds if no assets can be shown. Smaller enterprises that are not financially strong enough to establish their own infrastructure, should consider amalgamation with other small or large enterprises. The author is of the opinion that the possibility to obtain the necessary funds for the establishment of an own infrastructure without the required security, should exist with an efficient business plan. Insufficient planning in new enterprises is possibly the major contributing factor towards failure. Without investing capital at this early stage, new ideas can be tested on paper by means of planning. A literature study was undertaken to evaluate the opinions of various authors on a business plan. Factors for success in a good business plan were highlighted as follows: keep the business plan brief; do not over-diversify the enterprise; avoid describing technical products and manufacturing process in a way only comprehensible by an expert; organise and wrap the business plan effectively; the plan must be future orientated; avoid exageration; highlight critical risks; discuss and include any relevant problems; take care that the business plan is as complete as possible; and identify the target market and avoid ambiguous, vague and unrealistic statements. A business plan has been compiled for the purpose of this study. using the preceding information. Finally, a recommendation regarding future capital absorption and extension has been made to the company concerned.
AFRIKAANSE OPSOMMING: Die treilbedryf staan op die drumpel van vooruitgang. Hierdie vooruitgang gaan meebring dat beide die treilondernemings en die Staat hul beleidsformulering sodanig sal moet verander om aan Ie pas by die veranderende omstandighede. Die Staat sal byvoorbeeld daaraan moet dink om die bou van bote, wat at hoe duurder word, en die oprigting van infrastruktuur te subsidieer. iets wat weI in die buiteland gedoen word. Aan die anderkant sal beplanning en organisasie van treilondememings in nouer kontak met die Staat, wat verantwoordelik is vir die beheer van visbronne, moet geskied. Dit plaas 'n geweldige taak op die skouers van die Staat, want by sal beter navorsing moet doen oor visbronne en die beskikbaarheid van vissoorte. Hierdie inligting is van groot belang vir treilondememings wat moet beplan vir produksie en verkope in die toekoms. Die vooruitgang van treilondememings word egteT nie slegs deuT die Staat beinvloed nie, maar ook deur hul eie interne beplanning. Toekomstige ontwikkeling gaan definitief meer kapitaal van ondememings verg in die vorm van beter en meer modeme vang- en verwerkingstoerusting. In vandag se hoogs kompeterende en snelveranderende omgewing is dit moeilik om fondse te genereer veral as geen bates getoon kan word nie. Klein ondememings wat nie kapitaalkragtig genoeg is om 'n eie infrastruktuur op te rig nie, moet dit gewoonlik oorweeg om met ander klein of groot ondememings te amalgameer. Die navorser is van mening dat met behulp van 'n goeie besigheidsplan daar wei 'n moontlikheid behoort te bestaan om die nodige fondse, sonder die vereiste sekuriteit, te bekom om sodoende 'n eie infrastruktuur op te rig. 'n Gebrek aan beplanning by nuwe ondernemings is waarskynlik een van die grootste enkele bydraende faktore tot mislukking. Deur beplanning kan nuwe idees op papier op proef gestel word sonder om kapitaal op hierdie vroee stadium te investeer. 'n Literatuur ondersoek is onderneem om verskillende skrywers se menings ten opsigte van 'n besigheidsplan te evalueer. Suksesfaktore vir 'n goeie besigheidsplan is dan ook uitgelig: • hou die besigheidsplan kort; moet nie die onderneming oor-diversifiseer nie; venny dit om die tegniese produkte en vervaardigingsproses op so 'n manier, dat net 'n kundige dit kan verstaan, te beskryf; organiseer en verpak die besigheidsplan doelmatig; orienteer die plan volgens die toekoms; venny oordrewendheid; lig kritieke risiko's uit; bespreek en sluit enige toepaslike probleme in; sorg dat die besigheidsplan so kompleet as moontlik is; identifiseer die teikenmark en venny dubbelsinnige, vae en onwerklike stellings. Met hierdie kennis as agtergrond is 'n besigheidsplan opgestel wat vir die doel van hierdie studie gebruik is. Ten slotte is 'n aanbeveling aan die betrokke maatskappy gemaak met die oog op toekomstige kapitaalopneming en uitbreiding.

Full textThe fishing sector has been suffering a strong setback, with reduction in fishing stocks and more recently with the reduction of the fishing fleet. One of the most important factors for this decrease, is related to the continuous difficulty to find fish with quality and quantity, allowing the sector work constantly all year long. However other factors are affecting negatively the fishing sector, in particular the huge maintenance costs of the ships and the high diary costs that are necessary for daily work of each vessel. One of the main costs associated with daily work, is the fuel consumption. As an example, one boat with 30 meters working around 17 hours every day, consumes 2500 liters of fuel/day. This value is very high taking into account the productivity of the sector. Supporting this premise was developed a project with the aim of reducing fuel consumption in fishing vessels. The project calls “ShipTrack” and aims the use of forecasts of ocean currents in the routes of the ships. The objective involves the use of ocean currents in favor, and avoiding ocean currents against, taking into account the course of the ship, in order to reduce fuel consumption and increase the ship speed. The methodology used underwent the creation of specific Software, in order to optimize routes, taking into account the forecasts of the ocean currents. These forecasts are performed using numerical modelling, methodology that become more and more important in all communities, because through the modeling, it can be analyzed, verified and predicted important phenomena to all the terrestrial ecosystem. The objective was the creation of Software, however its development was not completed, so it was necessary a new approach in order to verify the influence of the ocean currents in the navigation of the fishing ship "Cruz de Malta". In this new approach, and during the various ship routes it was gathering a constant information about the instant speed, instantaneous fuel consumption, the state of the ocean currents along the course of the ship, among other factors. After 4 sea travels and many routes analyzed, it was possible to verify the influence of the ocean currents in the Ship speed and in fuel consumption. For example, in many stages of the sea travels it was possible to verify an increase in speed in zones where the ocean currents are in favor to the ships movements. This incorporation of new data inside the fishing industry, was seen positively by his players, which encourages new developments in this industry.
O sector pesqueiro tem vindo a sofrer um forte revés, com a redução dos stocks de pesca e mais recentemente com a diminuição da frota de pesca. Um dos principais fatores mais importantes para esta diminuição está relacionado com a contínua dificuldade em encontrar peixe com qualidade e em quantidade, permitindo ao setor trabalhar constantemente durante todo o ano. No entanto, outros fatores estão a afetar negativamente o setor pesqueiro, nomeadamente, os grandes custos de manutenção das embarcações e os elevados custos diários que são necessários para o trabalho de cada embarcação. Um dos principais custos associados ao trabalho diário é o consumo de combustíveis. Como exemplo, uma embarcação com 30 metros de comprimento e que trabalha cerca de 17 horas diárias consome cerca de 2500 litros de combustível por dia, valor muito alto tendo em conta a produtividade do setor. Suportando esta premissa foi desenvolvido um projeto com o objetivo de reduzir o consumo de combustível por parte das embarcações pesqueiras. Este projeto chama-se “ShipTrack”, e tem como finalidade a utilização de previsões de correntes marítimas nas rotas efetuadas pelas embarcações. O objetivo envolve um aproveitamento das correntes a favor e evitar correntes contra, tendo em conta o rumo do barco, de forma a diminuir consumos de combustíveis e aumentar velocidades de navegação. A metodologia utilizada passou pela criação de um Software específico, de forma a otimizar rotas tendo em conta a previsão das correntes oceânicas. Estas previsões são realizadas com recurso à modelação, mecanismo que tem cada vez mais importância em todas as comunidades, pois através da modelação, podemos prever, antecipar e verificar fenómenos importantes para todo o ecossistema terrestre. O objetivo inicial consistia na criação de um Software para o sector pesqueiro, no entanto o seu desenvolvimento não ficou concluído durante a realização deste trabalho. Assim foi necessária uma nova abordagem de forma a verificar a influência das correntes oceânicas na embarcação de pesca “Cruz de Malta”. Nesta nova abordagem, e durante as várias rotas realizadas, foi recolhida constantemente informação sobre a velocidade instantânea, o consumo instantâneo e o estado das correntes oceânicas ao longo do percurso do barco, bem como outros fatores. Após 4 viagens oceânicas e muitas rotas analisadas, foi possível verificar a influência das correntes oceânicas na velocidade do barco e no consumo de combustível. Por exemplo, em muitas fases das várias rotas realizadas, foi possível verificar um aumento da velocidade em zonas onde as correntes oceânicas se encontravam a favor do movimento do barco. A incorporação de novos dados na indústria da pesca foi vista positivamente pelos seus intervenientes, o que encoraja a novos desenvolvimentos nesta indústria.

The paper aims to design a new ship form for tuna fishery that increases the fishing automation and complies with the related current international regulations. The new form possesses a larger ship width, when compared with the traditional fishing vessels. At the same time, the form causes more spacious space than traditional fishing vessels. The main advantage appears to improve crew's living environment and working environment. A systematic comparison is made between the new ship form and the traditional ship form. The space distribution in the ship is also designed. This paper has finished the general arrangement of work habits of crew of our country, and this fishing boat adopts the system which throws ropes by the ship side. This system not only increases automation and saves manpower, but also prevents sea birds eating the baits. This design aims to increase the obtaining rate of fishing, and observe the common understanding of protecting sea birds. The main features of the new ship design include: 1. The stability is enhanced; 2. The space in the ship is markedly increased; 3. The indoor working area avoids the bad weather effects; 4. The ship installs the system which throws ropes by the ship side and saves working time and manpower; 5. The design of the ship length is shorter, in order to observe the trend of the international convention for the Safety of Life at Sea. According to the merits mentioned above, the new ship form is worthy of being adopted by the users.

Recently, owing to the transition of the fisheries, the fishing ports in Taiwan have encountered great difficulties causing parts of fishing ports have been left some extra spaces because of the decrease of the fishing boats. The Fisheries Agency has put quite emphasis on the issue, and has already implemented several measures in succession. Such measures like promotion of function-diverse fishing ports, the transformation of traditional fishing ports into modern fishing ports equipped with the function of fishery and tourism, the preservation of fishing ports’ basic functions, the assurance of fishery activities’ safety, and creation of fishing ports’ multiple values. The research has adopted Analytic Hierarchy Process to seek for the executive assessment pattern of establishing the yacht wharf at fishing ports. According to the references and questionnaires from the experts, the executive factors are divided into 4 aspects and 15 assessment principles, and the adoption of the experts’ questionnaires aimed at the group of scholars and engineers is applied to use AHP to analyze the comparative influence of each principle. The research takes Tainan fishing ports for example to plan on two projects to conduct reckoning and rank it according to the outcome. Finally, the best site to set up the yacht wharfs at Tainan fishing ports could be taken for example for relevant agencies to select the fishing ports for the yacht wharf construction in the future.

This thesis analyzes environmental problems coming along with the development of Aquaculture Industry. To respond existing problems, this thesis provides a new environmental prototype system, and takes Taiwan as the study background, where the prototype is demonstrated. Taiwan has been developing aquaculture industry for a long time, possessing outstanding techniques and providing major fish sources. To sustain fine aquaculture environment, pure water is largely needed when groundwater is the optimum source. However, over pumping groundwater causes several problems such as land subsidence which becomes a vicious circle and destroys natural balances. This thesis seeks solution to solve this problem. After actively understanding the demands and problems from the aquaculture population, this thesis devises 2 systems, Light-Breeding Shelter and Water-Storing Tank, to breed clean energy and harvest rainwater. This fish farm prototype provides a new water use mechanism, which avoids over pumping groundwater, and solar power system bringing self-sufficient energy or moreover supplying energy. Once when aquaculture industry barely consumes natural resources, the nature would recover itself gradually.

By reflecting on my personal experience of anti-gambling campaign and the issue of withdrawing the troops, I came to realize that my hometown is indeed a “militarized island” and therefore I began to explore the root cause of the outflow of population in Matsu’s fishing villages. It is apparent that most of the past researches and studies have deduced that the decreasing population in fishing villages and the emigration from Matsu is due to China’s overfishing instead of the influence from the military administration’s policies from 1956 to 1992. Therefore, this thesis provides an alternative perspective on Matsu Fishery issue by focusing on the fishermen families’ conditions during military administration period and analyzing how military administration has affected Matsu fishery. There are two intertwined mechanisms, the military fortification and the fortification of wartime economy, constructing the ruling of the military administration. The military fortification includes grassroot monitoring and mobilization, control of goods and migration of people, and monitoring political thoughts. The fortification of wartime economy is to use US aid to develop fishery economy based on the purpose of defense. With such two-fold mechanisms, the KMT government employed laws and regulations to legitimate its regime. The “Experimental Scheme of War Area Administration in Jinmen and Mazu” was therefore enacted to legitimize its military power and its control of the grassroot organnizations, productive enterprises, migration of people and goods, education, and various inspections. Meanwhile, the executive body of US aid in villages of Matsu, the Joint Commission on Rural Reconstruction, had been developing fishing industry to maintain livelihood of the fishermen, so they could lower the risks of having political turmoil while having stable food sources for the army. As the results of implementing the two-two mechanism, Matsu’s fishing industry had been constructed as “hard work with no future” and couldn’t support family’s livelihoods. The labor of Matsu’s fising industry began to decrease in 1961, which was also the beginning of the collapse of fishing villages. The shortage of labor in fishing industry now is resulted from the double impacts of military control and wartime economic policies, which led to the movement of labor to the prosperous commercial areas benefitted from the business with the military to perform non-fishing production, as well as the emigration of fishing labor to the Export-Processing Zones in Taiwan. Consequently, Matsu is facing the shortage of fishing labor, the decline of the fishery, and the dependence on the Mainland Chinese fishing labor.

Fishman Harbor! There is a one billion twenty millions “Fishman Harbor” coming up by seashore of Dongshi, with entwining highway road-net, as a new sightseeing-spot for citizens! However, smuggling aquatic products from mainland China flood in Taiwan and reduce the population of mariculture. But, who awares of these problems? Fishermen get into debts for mariculture, do part-time jobs for living, while the government just wouldn’t pay subvention even for flash flood. Under this kind of circumstances, the young generation couldn’t stay any longer, they drive away their hometown through road-net , and the signboard in “Fishman Harbor” says “have a nice sail”. Will it be a one-way sailing?

Fish lamps is the use of biological phototaxis when fishing the fish gathered in the shed of a network-wide patch fishing equipment, thereby increasing the catch when fishermen. LED lights use the current set of fish still need to match the high intensity discharge lamp HID, in order to achieve the effect of fish aggregating and shipboard operations lighting. So this thesis sentence LED fish lamp pole in both the boat and night lighting dual language into a purpose in accordance with the current shortcomings did not im-prove the simulation and discussion, secondary optics designed to simulate the light source through the secondary optics the light pattern to meet the needs of these objec-tives, and in Dialux lighting simulation software to simulate on your sea and pass only on the deck only illumination distribution, in order to confirm the set of this study fish lamps can replace traditional HID fishing light reaching fish aggregating language ship-board operations lighting dual purpose analog comparator illumination lighting space.
