Abstract:
The prevalence of bopyrid isopods, parasitic on penaeid prawn hosts, is recorded for the first time from a central Queensland prawn trawl fishery. The bopyrid parasite Parapenaeon prox. expansus has been recorded for the first time from the red spot king prawn, Penaeus longistylus, and the blue-legged king prawn, Penaeus latisulcatus. Previous unpublished reports of Parapenaeon japonicum parasitizing P. longistylus have also been substantiated. Parasite species were not randomly associated with all prawn species but rather were associated with a single prawn host species or species group. The factors that give rise to such specific host-parasite associations, particularly the host-selective behaviour of the parasite and the habitat preferences of the juvenile prawns, are discussed. Bopyrids had no significant effect on the weight of the prawns, but they did have a significant effect on ovary weight and histology, causing sterility in their hosts. High levels of infestation have been recorded from other fisheries (resulting in reduced spawning potential of the host population), but the low prevalence (0.32%) of bopyrid parasites in central Queensland prawns appears to be so low as not to present a concern at present.

Abstract Favaro, B., Duff, S. D., and Côté, I. M. 2013. A trap with a twist: evaluating a bycatch reduction device to prevent rockfish capture in crustacean traps. – ICES Journal of Marine Science, 70:114–122. Bycatch, or the incidental capture of non-target species, occurs in fisheries around the world, with often detrimental ecological consequences. Bycatch reduction devices (BRDs) that increase catch specificity have been used successfully in some fisheries, and the development of such devices remains an important component of the global effort to reduce bycatch rates. We tested novel devices designed to exclude juvenile rockfish (Sebastes spp.) from traps used to catch spot prawns (Pandalus platyceros), a commercially important species in British Columbia, Canada. The devices included reductions in trap opening sizes and novel bent-tunnel openings. Reducing trap opening size did not affect bycatch rates of rockfish or other non-target fish species. In contrast, bent-tunnel BRDs eliminated rockfish bycatch, and two of the bent-tunnel variants also excluded other fish species. However, prawn catch rates were reduced in all modified gear, and large prawns were often excluded more than small prawns. Videos recorded in situ revealed that prawn attempts to enter traps took longer and were more likely to fail in BRD-equipped than in unmodified traps. We conclude that bent-tunnel BRDs have the potential to be useful, but improvements are needed to increase prawn catch to levels similar to that of unmodified traps.

Abstract:
This paper describes and compares the sea snakes caught by vessels that target tiger prawns and endeavour prawns or that target the banana prawns Penaeus merguiensis and P. indicus. In 1989-90, 5203 sea snakes (14 species; 7 unidentified specimens) were purchased from fishers who trawled between Koolan Island and Cape York and participated in a dedicated carcass-tagging and data-collection programme. Hydrophines (11 species) represented 86.7% of the total catch. Aipysurines (3 species) represented 15.0% of specimens from vessels that targeted tiger prawns or endeavour prawns, but only 1.1% of specimens from vessels that targeted the banana prawns P. merguiensis and P. indicus. Prawn trawlers that operated between Koolan Island and Cape York during 1990 caught approximately 81 080 (� 13 670) sea snakes. Vessels that targeted tiger/endeavour prawns, P. merguiensis and P. indicus caught approximately 69260 (� 8750), 7200 (� 3250) and 4620 (� 1120) sea snakes respectively. The results emphasize the advantages of interactions between fishers and scientists and the need to assess separately the impacts of the three fisheries that constitute the northern prawn fishery.

Abstract:
Pengusahaan udang putih (Penaeus merguiensis De Man, 1888) di perairan sekitar Kotabaru memerlukan upaya pengelolaan agar perikanan udang dapat berkelanjutan.Salah satu informasi penting yang diperlukan sebagai dasar dalam pengelolaannya yaitu aspek biologi.Tujuan penelitian adalah mengkaji sebaran frekuensi panjang, hubungan panjang-berat, tingkat kematangan gonad dan rata-rata ukuran pertama kali matang gonad udang putih di perairan sekitar Kotabaru. Pengumpulan data diperoleh dari tempat pendaratan udang di Kotabaru pada bulan Januari – November 2016. Metode pengambilan sampel yang digunakan adalah random sampling. Hasil penelitian menunjukkan ukuran udang putih yang tertangkap cenderung kecil dengan ukuran berkisar antara 14 - 46 mmCL dan rata-rata sebesar 26 ± 3,7 mmCL pada udang jantan dan 28,5 ± 5,3 mmCL pada udang betina. Pola pertumbuhan bersifat allometrik negatif dan telah terjadi penurunan bobot dibandingkan beberapa tahun sebelumnya. Proporsi tertinggi udang matang gonad terjadi pada bulan Maret sehingga diduga merupakan puncak pemijahan udang putih.Ukuran pertama kali tertangkap udang (Lc = 28,1 mmCL) lebih kecil dibandingkan ukuran pertama kali matang gonad (Lm = 35,3 mmCL) sehingga sebagian besar udang yang tertangkap belum melakukan pemijahan. Dalam rangka menjaga keberlanjutan sumberdaya udang putih di Kotabaru, disarankan melakukan penutupan penangkapan di bulan Maret dan penggunaan alat tangkap ramah lingkungan dengan ukuran minimum tertangkap lebih besar dari 35 mmCL atau kurang dari 27 ekor dalam 1 kg.The exploitation of banana prawn (Penaeus merguiensis De Man, 1888) in Kotabaru Waters need management strategy, so the prawn fisheries in Kotabaru waters could be sustainably exploited. The important information needed for its basis management are was biological aspects of banana prawn. The aim of this research were to study about length frequency, length-weight relationship, maturity stages and length at first first mature of banana prawn in Kotabaru Waters. The research was conducted at landing site of prawn in Kotabaru and the samples were collected in January – November 2016. The method used for sampling was random sampling. The results showed that the size of banana prawn tend to become smaller with the size between 14-46 mmCL and the mean size were 26 ± 3,7 mmCL for male and 28,5 ± 5,3 mmCL for female. The growth pattern of banana prawn was allometric negative and the weights decreased from the previous years. The highest proportion of mature prawns was in March, likely suggestes to be the spawning season of banana prawn. Length at first captured of banana prawns (Lc = 28,1 mmCL) was lower than length at first matured (Lm = 35,3 mmCL) so most of prawns captured has not spawn yet. For sustainability of banana prawn resources in Kotabaru Waters, it is suggested to close fishing season in March and minimum legal size should be bigger than 35 mmCL or less than 27 prawns in 1 kg.

Abstract:
Integrated fisheries resource management is absolutely needed to achieve optimal result and sustainable utilization. This research aims to analyze the benefit of mangrove forest management for prawn fishing and mangrove timber production in Segara Anakan, southern coast of Central Java. The information concerning mangrove coverage changes was achieved from a satellite imagery (Landsat) from 2002 to 2009, while prawn resources stock assessment was analyzed through production surplus method and economic analysis of prawn fishing. The results show that the condition of mangrove ecosystem in Segara Anakan since 2002 to 2009 had been decreasing with average decrease rate of 10,28% each year which caused to prawn abundance. Utilization of mangrove wood inwhich aged above 20 years would give more benefit to prawn fishing and timber production. The additional economic value for prawn fishing was approximately 3,964 times of cropped woods. Prawn fisheries resource management in Cilacap coastal waters could be done by management of fishing effort and rehabilitation of mangrove forest in Cilacap region and surrounding areas as well especially in Segara Anakan Lagoon.

Abstract:
The potentially detrimental side-effects of prawn trawling are coming under increasing scrutiny in Australian waters, particularly in such ecologically sensitive areas as Queensland's Great Barrier Reef, and various restrictive measures are being suggested. Before changes are imposed on the prawning industry, the effects of trawling on the target prawn species and the long-term management of these effects need to be fully understood. Using a simulation model of a simplified prawn fishery, this paper describes the basis for the current regulatory mechanisms for Australian's prawn fisheries, in particular the manipulation of both the level and pattern of fishing effort. It is shown that even in moderately fished stocks, the fishery manager has several options, such as seasonal and nursery area closures, that are consistent with the goal of minimizing the impact of prawn trawling, while in no way penalizing the industry economically. With these in mind, possible ways of resolving or reducing the conflict with groups outside the prawning industry are discussed.

Full text
Abstract:
Fishermen's logbook data were used to describe the distribution of fishing effort and the composition of the commercial catches in Torres Strait. Catches consist of tiger, endeavour and king prawns. Additional information on the distribution and abundance of the individual species was obtained from four trawl surveys carried out at 3-monthly intervals during 1985. Each survey extended over the entire area of the commercial prawn fishery in Torres Strait. The species composition of the trawl surveys (48% tiger, 44% endeavour and 8% king) differed noticeably from that of the commercial catch (60% tiger, 36% endeavour, 4% king). This difference was attributed to a combination of the commercial fishery's concentration on the higher-priced tiger prawns and the different spatial and temporal distributions of the species. The tiger prawn catch consisted of two species, Penaeus esculentus (99.6%) and P. semisulcatus (0.4%). The king prawn catch comprised P. longistylus (97.5%) and P. latisulcatus (2.5%). The endeavour prawn catch was represented by a single species, Metapenaeus endeavouri. Spatial differences in the species distributions were found to be associated with the distribution of bottom sediments. Tiger prawns were most abundant on fine sediments with a mud content greater than 50%; P. semisulcatus was restricted to sediments with a mud content greater than 70%. The king prawns, unlike the tiger prawns, were most abundant on the coarse sediments with a mud content less than 20%. Endeavour prawns were the most widespread of all the species, being equally abundant on all sediment types.

Abstract:
Prawn fisheries are among the main sources of income in several tropical countries, where juveniles of many species inhabit estuarine wetlands. Although plants in these wetlands are considered to be essential food sources for juvenile prawns, some studies suggest that wetland producers are of limited importance. In the present study, δ13C and δ15N were used to identify differences in diet between penaeid species and size classes, and to determine if terrestrial wetland producers are important for nutrition. Two estuarine floodplain pools were sampled: one surrounded by mangroves and one surrounded by salt marsh. There were differences in diet between species and size classes. As mangrove δ13C (–29.7 to –26.3‰) was very different from salt marsh δ13C (–16.3 to –15.4‰), the importance of these producers was examined by comparing the isotopic composition of the prawns between sites and by using the IsoSource model. Although aquatic sources were the most important, salt marsh grass was also a significant contributor, supporting the hypothesis that these wetland producers are important for juvenile prawn nutrition. There was no evidence that mangrove material was of major importance for any species, suggesting that mangrove productivity is not the primary reason for the occurrence of penaeid prawns in mangrove habitats.

Abstract:
The effects of mola (Amblypharyngodon mola) at different densities in polyculture with freshwater prawn (Macrobrachium rosenbergii) were investigated at the Fisheries Field Laboratory, Bangladesh Agricultural University, Mymensingh. The experiment had three treatments, viz. prawn + 1 mola m-2, prawn + 1.5 mola m-2 and prawn + 2 mola m-2 and were treated as T1, T2, and T3, respectively with three replications in each. Prawn stocking density was same (3 juvenile m-2) in all treatments. Feeds were applied twice daily for prawn. Assuming 80% survival, feeding rates were gradually reduced to 10-5% of body weight from the beginning to the last month. Water quality parameters (except transparency, chlorophyll-a) did not vary significantly (P>0.05). Weight gain, SGR (% body weight), gross and net production of prawn were not significantly different (P>0.05). Higher total production was recorded in T3 (574.61 ±39.58 kg ha-1) followed by TI (531.65±42.40 kg ha-1) and T2 (514.75±77.91 kg ha-1). It was found that addition of mola at different densities had no effects on survival and production performance of prawn. Therefore, nutrient-dense mola may be stocked as an additional species with freshwater prawn. It might be concluded that treatment T3 was better proposition for prawn-mola polyculture.

Abstract:
In this study, the length-weight relationships (LWR) were estimated for six fish species captured during prawn fishing in the Lower Amazon region (Pará, Brazil). Prawn fishing boosts the socioeconomic development of riverine communities and is a relevant activity as a source of income and subsistence in this region. In addition, we registered new LWRs for the species Ossancora punctata and Hypoptopoma elongatum. The samplings were performed in prawn catches monthly from February 2018 to January 2019, using a “matapi”, which consists of a semi‑fixed trap that has a galvanized iron structure (2.5 m height by 2.0 m in length) and nylon mesh (1.40 x 1.60 mm mesh), and has two tapered openings to facilitate the entry and trapping of the prawn. The results show that 75% of the fish caught as prawn bycatches had not yet reached sexual maturity. Thus, it is clear that fisheries need to develop fishing gear that allow small fish to escape from the traps during the prawn fishery.

Abstract:
The monitoring and assessment of prawn populations in New South Wales (NSW), Australia, has been identified as a continuing research priority by both the fishing industry and the fisheries managers. This dissertation presents a series of dynamic population models developed to evaluate the status of the eastern king prawn (Melicertus plebejus) and eastern school prawn (Metapenaeus macleayi) populations within NSW and to analyse the relative performance of a number of alternative management strategies involving the three fisheries that target these species. Monthly commercial prawn catch and effort data from 1984 to 2006 were used to calibrate the stock assessment models. Where possible, the results of previous research were used to develop the structure of the model and to provide estimates of biological parameters. A process of increasing model complexity, including the addition of physical processes, such as river discharge events and economic considerations, was undertaken in an attempt to develop the most appropriate model for the analysis of management strategies. The first model presented was used to undertake a single-species assessment of the eastern king prawn stock and was based on a delay-difference population model with four different representations of recruitment. This model was calibrated to observations using the Bayesian sampling/importance re-sampling method and used to test the effect of significant changes in the future catch on the stock. The second model presented is a size-based metapopulation model which incorporated the dynamics of school prawns over three habitats, being harvested by three different fishing methods. This model was used to test the effect of alternative climate variability scenarios on the stock. The third model presented is a multi-species, multi-fishery bio-economic model. This model was used to examine the impact of nine alternative economic scenarios, incorporating various combinations of input costs and product prices. The results from the use of these models indicated that neither of the prawn population appeared to be over-exploited. The analyses also indicated that none of the alternative management strategies were found to stand-out enough to justify a move away from the current management strategy of input controls and spatio-temporal closures, even under a range of future scenarios including climate change and large movements in input costs and product prices.

Abstract:
Management of prawn trawling fisheries is a difficult task due to the competing interests of strongly motivated stakeholders and interest groups. This occurs because prawn trawling operations are technically complex, require large capital investments and exhibit high running costs while owners have limited property rights over the resources that they harvest. Prawn stocks are public resources and are managed with a view to provide maximum benefit to the broad community. Additionally their exploitation also involves the incidental capture of significant numbers of other animals of no commercial value (bycatch) and causes impacts on seabed morphologies, which are involved in many diverse ecosystem processes. At the policy level an intention to manage trawl fisheries in a comprehensive way is backed by a mandated approach that is designed to capture all of the above issues and interests. That approach is termed Ecological Sustainable Development (ESD). The work in this thesis is designed to produce a prediction tool for prawn trawling performance that is based on modelling the physical nature of prawn trawling activities. It is proposed that the resulting tool is essential for working to manage the multi-dimensional aspects of prawn trawling fisheries. Three discrete objectives for the thesis are; to expand and improve an existing Prawn Trawling Performance Model (PTPM) so that it is more accurate and relevant to a broader range of questions, to evaluate the capacity of the PTPM to predict the performance characteristics of real prawn trawling operations in terms of both engineering and catching performance and to investigate the problem space surrounding prawn trawl fisheries to identify and develop applications for the model. A rudimentary PTPM (Sterling 2000b) is expanded through the analysis of further empirical data collected for model and full-scale trawl gear.ght area of improvement to the PTPM were considered and in all cases significant changes were made. The accuracy of the new form of the model is here tested by comparing performance predictions with measurements of trawling performance for a variety of industrial trawl systems operated in the Queensland East Coast Trawl Fishery and also through comparing predicted trawling performance with prawn catches returned for trawlers operating in the Northern Prawn Fishery over the years 1970 to 2000. In the first case, errors in predicting swept area rate, considered an important performance parameter, were less than 5%. Fine scale issues were explored using the available sea mal data and a number of areas of concern within the model are highlighted. These relate to accurately quantifying the forces involved in the interaction of the trawl gear with the seabed and accurately accounting for the interaction between components within trawl systems. In the second case, the results suggest that between 50% and 60% of the variation in the seasonal catching performance of trawlers in the NPF is explained by predictions of swept area rate derived by the PTPM from the available data for that fishery. A comprehensive survey of applications for the PTPM is conducted in context with approaching the management of prawn trawling fisheries using the principles of ESD as defined by the National Strategy for ESD (1992). The Northern Prawn Fishery is used as a case study to explore in finer detail applications for the PTPM. Issues arising from the implementation of some of the applications are discussed.

Environmental changes leading to stressful situation have been shown to alter the animals respiration and metabolism to a great extent. In addition, procedures adopted in aquaculture techniques such as handling of animals, confinement, transport and disease treatments cause a variable degree of trauma in them. These factors can adversely affect the overall production of animals in a culture system

Aquaculture has been on the focus in recent years the worldover to augment food production. It's success involves techniques on handling, crowding, confinement, transport, nutrition and ecological management. A flaw in any one of these will adversely affect the physiology of fish leading to pathological conditions and mortality. Seed and feed are the 2 major constraints in most of the culture systems, which hatcheries and factories can take care of. But problems on handling and transport still loome large; since causes that adversely affect the animals are difficult to ascertain with certainity in most cases even today.

Vibriosis in shrimp culture causes about 80% mortality. In the present study. Vibrio isolated from diseased Penaeus monodon was characterized as Vibrio alginolyticus. The physical, cultural and biochemical investigations carried out in the study confirmed the isolate. Growth of V.alginolyticus in Zobell marine broth indicated no lag period, while the peak growth was observed at 18 hours. V.alginolyticus was found to cause mortality in healthy shrimps in artificial infection studies. One hundred percent mortality was noted at 5.7x10 cells, 5.7x10 cells, 5.7x10 cells per P.monodon. Reisolation studies indicated the presence of the same bacteria in haemolymph and other body tissues.

Abstract:
An important adaptation in organisms to withstand osmotic variations in their external medium, is their efficiency of regulating intracellular concentration. In this context, cell volume regulation appears as a fundamental mechanism. The problem of cell volume regulation becomes crucial in the establishment of organisms in aquatic environment with fluctuating osmolarities.

Abstract:
The presented work investigated the extent by which Reynolds number determines the drag coefficient for high porosity nets at a low angle of attack. A simple prawn trawl model that incorporates the main design features of prawn trawls employed in Australia was developed. Four trawl models of various high porosities were tested in a flume tank with respect to drag and shape over a range of flow velocities. The physical trawl model was analysed as a system of independent plane net sheets, each with an orientation to the flow estimated from analysis of stereo-vision data. The main finding was that the drag coefficient was weakly dependent on the Reynolds number in the range typical for prawn trawl operations, 1000<Re<1700. These combined findings imply that trawler operators can approximately estimate prawn net drag from a function containing trawl twine area, towing speed and spread ratio.

Abstract:
In prawn-trawling operations, otter boards provide the horizontal force required to maintain net openings, and are typically low aspect ratio (∼0.5) flat plates operating on the seabed at high angles of attack (AOA; 35–40°). Such characteristics cause otter boards to account for up to 30% of the total trawling resistance, including that from the vessel. A recent innovation is the batwing otter board, which is designed to spread trawls with substantially less towing resistance and benthic impacts. A key design feature is the use of a sail, instead of a flat plate, as the hydrodynamic foil. The superior drag and benthic performance of the batwing is achieved by (i) successful operation at an AOA of ∼20° and (ii) having the heavy sea floor contact shoe in line with the direction of tow. This study investigated the hydrodynamic characteristics of a generic sail by varying its twist and camber, to identify optimal settings for maximum spreading efficiency and stability. Loads in six degrees of freedom were measured at AOAs between 0 and 40° in a flume tank at a constant flow velocity, and with five combinations of twist and camber. The results showed that for the studied sail, the design AOA (20°) provides a suitable compromise between greater efficiency (occurring at lower AOAs) and greater effectiveness (occurring at higher AOAs). At optimum settings (20°, medium camber and twist), a lift-to-drag ratio >3 was achieved, which is ∼3 times more than that of contemporary prawn-trawling otter boards. Such a result implies relative drag reductions of 10–20% for trawling systems, depending on the rig configuration.

Abstract:
Background Most of Australian prawn aquaculture production is based on P. monodon. However, the Australian industry is under intense competition from lower priced overseas imports. The availability of all-female monosex populations, by virtue of their large size and associated premium prize, will offer competitive advantage to the industry which desperately needs to counteract competitors within this market. As for the redclaw production in Israel, although it is at its infancy, the growers realized that the production of males is extremely advantageous and that such management strategy will change the economic assumptions and performances of this aquaculture to attract many more growers. Original objectives (as in original proposal) Investigating the sex inheritance mechanism in the tiger prawn. Identification of genes expressed uniquely in the androgenic gland (AG) of prawns and crayfish. The above genes and/or their products will be used to localize the AG in the prawn and manipulate the AG activity in both species. Production of monosex populations through AG manipulation. In the prawn, production of all-female populations and in the crayfish, all-male populations. Achievements In the crayfish, the AG cDNA library was further screened and a third AG specific transcript, designated Cq-AG3, had been identified. Simultaneously the two AG specific genes, which were previously identified, were further characterized. Tissue specificity of one of those genes, termed Cq-AG2, was demonstrated by northern blot hybridization and RNA in-situ hybridization. Bioinformatics prediction, which suggested a 42 amino acid long signal anchor at the N-terminus of the deduced Cq-AG2, was confirmed by immunolocalization of a recombinant protein. Cq-IAG's functionality was demonstrated by dsRNA in-vivo injections to intersex crayfish. Cq-IAGsilencing induced dramatic sex-related alterations, including male feature feminization, reduced sperm production, extensive testicular apoptosis, induction of the vitellogeningene expression and accumulation of yolk proteins in the ovaries. In the prawn, the AG was identified and a cDNA library was created. The putative P. monodonAG hormone encoding gene (Pm-IAG) was identified, isolated and characterized for time of expression and histological localization. Implantation of the AG into prawn post larvae (PL) and juveniles resulted in phenotypic transformation which included the appearance of appendix masculina and enlarged petasma. The transformation however did not result in sex change or the creation of neo males thus the population genetics stage to be executed with Prof. Hulata did not materialized. Repeated AG implantation is currently being trialed. Major conclusions and Implications, both scientific and agricultural Cq-IAG's involvement in male sexual differentiation had been demonstrated and it is strongly suggested that this gene encodes an AG hormone in this crayfish. A thorough screening of the AG cDNA library shows Cq-IAG is the prominent transcript within the library. However, the identification of two additional transcripts hints that Cq-IAG is not the only gene mediating the AG effects. The successful gene silencing of Cq-IAG, if performed at earlier developmental stages, might accomplish full and functional sex reversal which will enable the production of all-male crayfish populations. Pm-IAG is likely to play a similar role in prawns. It is possible that repeated administration of the AG into prawn will lead to the desired full sex reversal, so that WZ neo males, crossed with WZ females can result in WW females, which will form the basis for monosex all-female population.
