Resumen

For over two decades, Indonesia has reported higher average shark landings than any other nation, but very little local information exists on the fishery and life histories of targeted species. This poses severe challenges to shark sustainability and conservation in this vast archipelago. We draw on diverse sources of data to evaluate the sustainability of the shark fishery in eastern Indonesia, a particularly data-poor region where sharks are primarily targeted for their fins. Shark fishers from three coastal communities were interviewed on their perceptions of catch trends over the past twenty years and asked to collect fishing data during fishing trips in the Seram, Arafura and Timor Seas. For the most frequently harvested species, we estimated maximum intrinsic rates of increase (rmax) to predict their resilience to fishing pressure. Our results indicate that shark fishing practices in the region are likely to be unsustainable. The catches of several species largely comprised of immature individuals and most fishers attributed observed declines in shark numbers, size and species diversity to overfishing. Hammerhead sharks have relatively high intrinsic resilience but are nevertheless at risk of local extinction due to their availability to the fishery and the value of their fins. Sandbar, dusky and grey reef sharks have lower resilience and are frequently caught but not managed. We recommend a composite management approach, including consistent implementation of existing trade restrictions, fisheries research and opportunities for fishers’ livelihood diversification, to stem shark harvests in eastern Indonesia.

Resumen

The zonation review and evaluation took into account habitat protection areas and categorised migration routes. In addition, the sustainability of fishery resources is maintained, as people in Savu Sea depend on fishery resources. The objectives of this research are to analyse the effectiveness of sub-zone cetacean protection for Savu Sea National Marien Park. The research stations were watering inside and outside in Savu Sea National Marine Park. The sampling of the research was conducted on 2015 and 2016, collecting data using a zig-zag transect by observation method of collecting data sighting cetacean with single observer platform. The results of sub-zone cetacean protection against Southwest Sumba waters, West Sumba and East Timor Land need to be reviewed if referring the current zoning area. Sub-zone for areas to protect sustainability cetacean need to be adjusted addition and alteration of fishery zone, the area of Southwest Sumba, West Sumba and Central Sumba is ± 445,567.44 ha and ± 239,307.52 ha to around East Timor Land waters. Extensive re-evaluation of existing protection sub-zones is requiring. A review of extent to efectiveness water areas attend the conflict of interest in needs of fisherman to catch and migration route of cetacean.

Resumen

This paper aims to describe the conceptual model of informal business development applied to “Tibo-Tibo” fisherwomen in North Minahasa Regency. Data and information were obtained by observation and structured interviews to “Tibo-Tibo” fisherwomen, business partners and village governments. The data was analyzed qualitatively by using Miles Huberman perspective, through stages: data reduction, data presentation, conclusion drawing and verification. After going through the validity of experts, this paper produced a conceptual model of informal business development based on intellectual capital namely human capital, social capital and organizational capital. This paper recommends that through the intellectual capital approach "Tibo-Tibo" fisher women's business can be improved through empowerment. Empowerment in the form of human capital will increase the added value products with the availability of a variety of products for frozen food businesses and products for culinary businesses. Empowerment in the form of social capital will strengthen the values of relationships with business partners, trust to customers and employees and strengthen the work culture "mapalus" (local wisdom for the community) such as cooperation and helping each other. Empowerment in the form of organizational will strengthening the management and organizational professionalism as well as the acknowledgment of business license and product brands by consumers.

Resumen

A key challenge of the environmental regulatory framework for offshore petroleum activities in Australia is the requirement to demonstrate acceptability, with the legislation placing the onus on petroleum titleholders to demonstrate that the impacts and risks posed by an activity will be of an acceptable level and reduced to as low as reasonably practicable. This paper presents a case study on the assessment of noise impacts to fishes for the Bethany 3D Marine Seismic Survey, which was acquired by Santos Ltd in mid-2018. The survey area was encompassed entirely by the Oceanic Shoals Marine Park, and also overlapped a significant proportion of the Timor Reef Fishery, a regionally important demersal scalefish fishery. The survey area overlapped a key ecological feature and a range of geomorphic features characterised by benthic habitats supporting demersal and benthic fish communities, including site-attached species. On this basis, the evaluation of impacts and risks required a multi-faceted approach, with seven key elements: (1) acoustic modelling; (2) application of sound exposure guidelines; (3) a quantitative risk assessment (benthic habitat predictive modelling and spatial analysis of site-attached fish assemblages); (4) the definition of an acceptable level of impact; (5) a sound source verification process; (6) engagement with key stakeholders; and (7) an independent, expert peer review process. The outcomes of each of these steps were incorporated into the environment plan, and enabled the titleholder to demonstrate that, with adopted control measures in place, environmental impacts and risks from the seismic survey could be managed to an acceptable level.

Resumen

Development in the marine and fisheries sector is supported by opportunities for resource utilization and management that are distributed in three Fishery Management Areas (WPP), namely the Banda Sea (WPP 714), Seram Sea and Tomini Bay (WPP 715), Arafura Sea and Timor Sea (WPP 718). The fishery sector in Maluku creates opportunities for commercial businesses in the industrial sector, both in cultivation, fishing and processing, including small and large businesses. A fishery commodity that has good prospects and benefits fishing communities is seaweed cultivation. The West Seram District Government in its development policy has placed the Eucheuma cottonii seaweed commodity as a leading commodity to be developed. Youth roles are needed in cultivation activities, so it can be said that youth tend to place economic interests above other interests in determining how and where they should play a role in development. Share factor analysis is used to measure the contribution of youth income to family income and total family income is calculated by adding up youth income and family income.

Resumen

More than 300 sea cucumber species have been recorded from Indonesian waters. This paper presents eight species which have been rarely reported. Actinopyga bannwarthi Panning, 1944, were found among fished sea cucumbers collected by fishermen in Kupang and Karimunjawa. Stichopus pseudohorrens Cherbonnier, 1967, was found in West Timor waters; Thelenota rubralienata Massin & Lane, 1991, and A. caerulea Samyn, Vandenspiegel & Massin, 2006, were collected from the reef in Halmahera, North Maluku. Four other species i.e. Bohadschia atra Massin, Rasolofonirina, Conand, Samyn, 1999; B. subrubra Quoy and Gaimard, 1833; Holothuria (Metriatyla) fuligina Cherbonnier, 1988, and H. (Thymiosycia) gracilis Semper, 1868, were discovered from Lombok waters. The latest mentioned species was also found among fished sea cucumbers in Karimunjawa. All species except T. rubralineata may be new records for Indonesia. In the case of H. (Thymiosycia) gracilis Semper, 1868, it was new record for Lombok waters, following its discovery from West Seram, Central Maluku.

Resumen

Abstract Skipjack tuna is one of the potential fishery commodities in the waters of Timor, East Nusa Tenggara. This fish is exploited throughout the year without any management policies. This study aims to analyse population dynamic parameter. Length data were collected at the Oeba Fish Base from April to December 2020. Data analysis, size structure and age group of the Bhattacharya method, the L∞ and K values of the Ford and Walford method, total mortality by length catch converted curve, natural mortality by Pauly method, Y/R using the Beverton and Holt method. The results showed that the smallest fish was 27 cm FL, the largest was 71 cm FL, the dominant size is 55-58 cm FL and the average length was 48,68 ± 10,67 cm FL, L∞ 91.00 cm FL, and K 0.51 year1. The population consists of three age groups, the values of Z, M, F and E are 2.64 year1, 0.86 year1, 1.78 year1, and 0.68 year1 respectively. Current Y/R and optimal Y/R values are 0.036 and 0.060 grams recruit1 respectively. The conclusion, the high mortality of skipjack tuna is caused by fishing activities, and the high level of exploitation causes the recruitment process to be not optimal.

Resumen

Water is one of the basic human needs for various daily needs. One source of water that is often used by the general public is river water. With proper utilization, river water can support the economic development of the surrounding community. The main priority for water use is for domestic use such as drinking water and household needs and also used for industrial, agricultural, plantation, livestock, fishery, and so on. Optimal use of rivers for irrigation areas must be supported by information related to river conditions and buildings in rivers. Therefore it is necessary to make a database related to river conditions and irrigation building conditions. One of the software used in making a river database in the Provincial Irrigation Authority on Timor Island is Quantum Geographic Information System (QGIS) because it is open-source software that does not require a license but provides ample room for users to add functions such as software other paid mapping.

Resumen

AbstractThe Spratly Islands archipelago has become pivotal as a strategic, economic and political asset in the South China Sea. This situation has become particularly evident since the end of the Cold War, as the Spratlys have been used by six littoral states as legal basepoints to project claims over strategic sea-lanes, fishery waters and submarine hydrocarbon resources in the South China Sea. The claimant state having predominant military and economic influence in the region is China, which has used military force on occasion to substantiate its claims. It is not inconceivable that the dispute over the Spratlys could lead to military conflict. Successful settlement of sovereignty disputes for the Timor Gap area, Antarctica and the Svalbard archipelago provide models for creating a joint resource development authority to promote regional co-operation among Spratly claimants. The most critical ingredient for mitigating tensions in the South China Sea is the political willingness of Spratly claimants, especially China, to make dispute settlement happen.

Resumen

Climate changes will lead to a worsening of the ecological conditions, in terms of hydrological instability and rising water temperatures, of the Mediterranean rivers. Freshwater fishes inhabiting this area can be threatened in the near future by accelerating drought and decreased ecological connectivity. The main aim of the research was to analyze changes in the distribution of the endemic freshwater fishes Padogobius nigricans, Squalius lucumonis and Telestes muticellus in the Tiber River basin (Italy), within a proven period of climate warming, in terms of increasing water temperature and droughts. A multivariate analysis was conducted using fish and environmental data collected in 117 sites over the years 1990–2017. For the three species, population abundance, age structure and body condition were analyzed. Detectability, occupancy, local extinction and colonization processes were also examined. We showed that S. lucumonis and T. muticellus have shifted their distributions upstream, likely in order to reach their thermal optimum. Padogobius nigricans did not move upstream significantly, since the species is characterized by limited vagility and thus a low dispersal capability in a context of high river fragmentation. In the study area, elevation and river barriers seem to play a key role in extirpation and colonization processes; for S. lucumonis and T. muticellus the extinction probability decreased with increasing altitude, while for P. nigricans the colonization probability decreased with an increasing degree of river fragmentation. These results highlight how species-specific dispersal ability can lead to varying adaptability to climate change.

Resumen

Saltwater crocodiles (Crocodylus porosus) are potentially dangerous to humans, yet they have major cultural value to many people in Timor-Leste. Recent increases in attack risk are influencing traditional attitudes, threatening culls of remaining wild crocodile populations. To understand patterns that may assist mitigation, we compiled attack records for the period of April 2007 to April 2014, using the CrocBITE online database. Recorded attacks (n=45) showed a high fatality rate (82.2%), the majority (77.8%) being recorded since 2010. The highest proportion of attacks (46.7%) occurred in southern coastal wetlands suited to crocodiles, areas representing major sources of food, livelihoods and ecosystem services (i.e. fisheries, timber, coastal protection) for locals. Subsistence fishing posed the highest attack risk, particularly from September to February when food security is low. Attacks matched gender roles (most victims were males, the primary fishers) and demographic patterns (teenagers, the fastest growth group, comprised the highest proportion). Predicted increases in food insecurity, fishing activities, coastal impacts and rising human and crocodile populations pose worrying implications for human–crocodile conflict. We recommend essential baseline surveys enabling meaningful management decisions, and suggest that tailored management and educational awareness based on proven existing models could substantially mitigate attack risk while remaining compatible with traditional Timorese attitudes towards crocodiles.

Resumen

To overcome pests and diseases of rice farming, farmers always rely on information and knowledge from agricultural experts for decision making. The problem is that experts are not always available when the farmers need and the cost is quite high. Pests and diseases elimination is hard to be done individually since the farmers are lack of knowledge about the pest types that attack the rice fields. The objective of this study is to build a knowledge-based system that can identify pests and diseases interactively based on the information that has been told by the farmers using SMS communication services. The system can provide a convenience way to the farmers in delivering pests and disease problem information using a natural language. The text mining method performs tokenizing, filtering and porter stemming that used to extract important information sent by a SMS service. The method of Jaccard Similarity Coefficient (JSC) was used to calculate similarities of each pest and disease based on symptoms that are sent by the farmers through SMS. The corpus database usedin this study consists of 28.526 root words, 1.309 stop wordsand 180 words list. Pest and disease database reference in this study was obtained from the Ministry of Agriculture and Fisher (MAF) Timor-Leste. The result of the experiment shows that the system is able to identify the symptoms based on the keywords identified with the accuracy of 81%. The result of pest and disease identification has the accuracy of 86%.

Resumen

In running waters, under climate change conditions, the combined effect of water warming and decreasing flow rates may encourage colonisation by invasive cool and warm-water fish species. The aim of the study was to analyze the potential climate change effects on the spread of four invasive alien fishes in the Tiber River basin, taking into account the effects of river fragmentation. Fish and environmental data collected in 91 sites over the years 1998–2018, were used to analyze temporal changes in their habitat requirements. A multivariate analysis was conducted, and the hypothesis of a range expansion towards the upstream reaches has been tested. For Barbus barbus, Gobio gobio, Padogobius bonelli and Pseudorasbora parva population abundances and body condition were analyzed. Detectability, occupancy, local extinction and colonization probabilities were estimated. We showed that B. barbus and P. bonelli have significantly extended their range toward upstream. P. parva did not move toward higher altitudes significantly, suggesting that, at this stage, the species has probably reached an equilibrium. River fragmentation, elevation, water temperature and average current speed seem to be major determinants in colonization processes, affecting the dispersal ability of the species. Not surprisingly for species introduced in relatively recent times, the colonization probabilities were much higher than extinction probabilities. Our results provided evidence for some synergistic effects between climate changes and alien fish species invasions, in terms of species range shifts mediated by rising water temperatures, although they should be interpreted cautiously, taking into account that these species most likely were not yet stabilized.

Resumen

Sharks represent 78% of the total catch by weight of a Taiwanese surface gill-net fishery off northern Australia. Two carcharhinids, Carcharhrnus tilstoni (previously described as C. limbatus) and C. sorrah, together comprise 83% of this shark catch by number. C. tilstoni is distinguished from C. limbatus by differences in enzyme systems, vertebral counts, size data and pelvic fin coloration. Of the specimens of C. tilstoni and C. sorrah caught in the Arafura and Timor Seas from 1981 to 1983, 43% and 47%, respectively, were female; at birth these proportions were 46% and 50%, respectively. In both species, females tended to be relatively more abundant in catches of mature fish, except around March, when males predominated. In northern Australia, the usual size at maturity for C. tilstoni is 110 cm for males and 115 cm for females; for C. sorrah, it is 90 cm and 95 cm, respectively. Both species exhibit placental viviparity and have almost identical restricted reproductive cycles. Mating occurs in February-March, ovulation in March-April and the main parturition period is in January. The gestation period is 10 months and individual fish breed each year. The average litter size for both species is three. The size at birth is about 60 cm for C. tilstoni and 50 cm for C. sorrah. Stomach contents indicate that teleost fish are an important component of the diet of both species and there is some indication of a change in feeding depth with shark size.

Resumen

Small-scale fisheries are responsible for landing half of the world’s fish catch, yet there are very sparse data on these fishing activities and associated fisheries production in time and space. Fisheries-dependent data underpin scientific guidance of management and conservation of fisheries systems, but it is inherently difficult to generate robust and comprehensive data for small-scale fisheries, particularly given their dispersed and diverse nature. In tackling this challenge, we use open source software components including the Shiny R package to build PeskAAS; an adaptable and scalable digital application that enables the collation, classification, analysis and visualisation of small-scale fisheries catch and effort data. We piloted and refined this system in Timor-Leste; a small island developing nation. The features that make PeskAAS fit for purpose are that it is: (i) fully open-source and free to use (ii) component-based, flexible and able to integrate vessel tracking data with catch records; (iii) able to perform spatial and temporal filtering of fishing productivity by fishing method and habitat; (iv) integrated with species-specific length-weight parameters from FishBase; (v) controlled through a click-button dashboard, that was co-designed with fisheries scientists and government managers, that enables easy to read data summaries and interpretation of context-specific fisheries data. With limited training and code adaptation, the PeskAAS workflow has been used as a framework on which to build and adapt systematic, standardised data collection for small-scale fisheries in other contexts. Automated analytics of these data can provide fishers, managers and researchers with insights into a fisher’s experience of fishing efforts, fisheries status, catch rates, economic efficiency and geographic preferences and limits that can potentially guide management and livelihood investments.

Resumen

Subgeneric classification of Chrysodema Laporte de Castelnau & Gory, 1835 is revised and following synonymy is established: Chrysodema=Cyalithoides Fisher, 1922 syn. nov.; Pseudochrysodema Saunders, 1874=Leganya Hołyński, 1994 syn. nov.,=Marcsikiella Hołyński, 2014 syn. nov. Four subgenera are recognized as valid: Chrysodema s. str., Gelaeus Waterhouse, 1905, Pseudochrysodema Saunders, 1874, and Thymedes Waterhouse, 1905, and a key to the subgenera is given. Four species-groups are established in the subgenus Chrysodema s. str.: C. aeneoviolacea-group, C. aurostriata-group, C. eximia-group, and C. sonnerati-group. All known species, except the currently accepted synonyms of Chrysodema (Chrysodema) eximia Laporte de Castelnau & Gory, 1835, included in these groups are revised based on comparative study of extensive material including types of all described taxa. Three new species and one subspecies are described: Chrysodema (Chrysodema) dany sp. nov. from Haruku Island, Indonesia; C. (C.) gottwaldi sp. nov. from Palawan Island, Philippines; C. (C.) lewisii nakatai subsp. nov. from Yaeyama Islands, Japan; and C. (C.) vrabeci sp. nov. from Thailand and Laos. Chrysodema (C.) aeneoviolacea Deyrolle, 1864 stat. rev., C. (C.) dohrnii Saunders, 1874 stat. rev., and C. (C.) fuscitarsis Kerremans, 1895 stat. rev. are removed from synonymy with C. (C.) mniszechii Deyrolle, 1864; C. (C.) tonkinea Kerremans, 1909 stat. rev. is removed from synonymy with C. (C.) aurostriata Saunders, 1866. Three new synonymies are established: C. (C.) aeneoviolacea=C. (C.) elongata Kerremans, 1900 syn. nov.=C. (C.) keyensis Théry, 1923 syn. nov. (the latter was formerly synonym of C. (C.) elongata); C. (C.) dohrnii=C. (C.) fairmairei Kerremans, 1895 syn. nov. (formerly synonym of C. (C.) mniszechii). Neotype is designated for C. (C.) sonnerati Laporte de Castelnau & Gory, 1835 and lectotypes are designated for following taxa to ensure their correct application and recognition in future: C. (C.) aurostriata, C. (C.) fairmairei, C. (C.) fuscitarsis, C. (C.) sumatrensis Kerremans, 1895, C. (C.) tonkinea, C. (C.) yerburyi Waterhouse, 1905, C. (P.) coelestina Obenberger, 1922, and C. (P.) inslabilis Deyrolle, 1864. Additionally, dark species of the subgenus Pseudochrysodema are revised and as a result C. (P.) coelestina stat. rev. and C. (P.) instabilis stat. rev. are removed from synonymy with C. (P.) radians (Guérin-Méneville, 1830) and a new species C. (Pseudochrysodema) jakli sp. nov. is described from Timor Island, Indonesia. All herein included taxa are illustrated with colour photographs of habitus and the male aedeagus when available. All new taxa are diagnosed and a key to species of the C. aeneoviolacea-group is given.

Resumen

The threatened grey nurse shark (Carcharias taurus) is reported for the first time from oceanic coral reefs in the Timor Sea. Generally known from temperate and subtropical coastal reef habitats, this species was encountered by Indonesian traditional fishers on oceanic coral reefs in an area of the Australian Exclusive Economic Zone known as the 1974 MoU Box, some 200 km from the Australian mainland. The presence ofC. tauruson these remote tropical reefs bears important management implications, including the species’ protected status in Australian waters and the challenges of regulating catches in areas permitted for traditional Indonesian fishing.

Resumen

The island of Atauro is a tourist destination located in Dili District of East Timor.The island has big potential for tourist attractions that deserves to be further developed to be tourist destinations. This study aims to investigate the potential tourist attractions, the internal and external environmental conditions as well as to formulate strategies and programs for sustainable tourism development. This study used IFAS (Internal Factor Analysis System) and EFAS (External Factor Analysis System) are used. This study applies planning theory, tourism area life cycle by Butler, planning and Participation Theory. Data are collected through observation, interviews, and questionnaires.The results showed that there is potential to further develop some tourist attractions in Atauro to be sustainable tourism. Unspoiled natural view, underwater panoramic, extended coral-reef with varieties of fishes, forest with various birds, unique social and cultural life are some of the potential areas for development. The analysis on internal and external environment showed that Atauro is categorized into cell I Grow and Development (the concentration is via vertical integration). The potential for tourism in Atauro Island mainly lays in marine, culture, beaches, history, biking, spring water, seaweed cultivation, cave, spirituality, and sightseeing adventure. The strongest factor of internal environmental condition is the panoramic view, while the weakest factor is the inadequate facilities and infrastructure.

Resumen

Sociality and ecological drivers that can influence individual association patterns are infrequently considered in wildlife management, although they are essential aspects affecting animals’ responses to both human-related pressures and conservation strategies. In common bottlenose dolphins (Tursiops truncatus), sex-specific social dynamics and interactions with anthropogenic activities may affect grouping and induce changes in relationships between individuals. Out of a total of 347 individuals, we assessed the level of association among 68 bottlenose dolphins that have been sighted more than five times near the Roman coast (central Mediterranean Sea, Italy). The half-weight index (HWI) of dyadic associations, their network relations, and stability over time were investigated by using the SOCPROG software. Outcomes showed that females were more strongly associated than other individuals, with both preferred constant short-term associations and random long-term associations, possibly resulting in greater success in rearing young. Individuals interacting with the bottom trawl fishery showed weaker and short-term associations. Temporary disruption of individual associations during interaction with fishery and the relatively low number of females with calves participating in depredation seem to denote both the opportunistic nature of interactions with fishing vessels and the offspring-related protection strategy. The results show that the dolphins in this region maintain a complex but flexible social structure that varies with local biological requirements and is resilient to anthropogenic pressures.

Resumen

Abstract In 2020 and 2021, fish-kills events occurred in the Tiber river in the city of Rome. These events, which caused the death of thousands of fish of different species (e.g., Barbus spp., Cyprinus carpio, Squalius spp.), were preceded the days before by severe flash-storms. Heavy rains in urban areas in recent years are linked to climate change and fish-kills events. With the aim to investigate the causes of these events, effect-based methods (EBMs) and targeted chemical analyses have been performed on a specific site of river Tiber in the center of the city. Additionally, examination and classification of the floating dead fishes have been performed. The chemical analysis performed on several groups of contaminants showed the presence of some pharmaceuticals, insecticides, and PFAS at up to ng/L. Results with the Fish Embryo Toxicity (FET) test confirmed lethal and sub-lethal effects, while acute effects were not detected with the Daphnia magna acute test. The fish-kills events probably can be generated by several factors as a consequence of an increasing human anthropization of the area with the contribution of different stressors together with chemical releases and emissions. This study shows that in multiple stressor scenarios characterized by heavy rainfall, droughts, and strong anthropogenic pressures, the application of EBMs, chemical analysis, and fish assemblage examinations can represent a useful support in the investigation of the causes of extensive fish-kills events.

Resumen

The parliamentary control of executive power in foreign affairs in Germany suffered two severe blows last November; one may wonder whether it will ever recover. First, on 16 November 2001, Chancellor Gerhard Schröder transformed one of the most important foreign policy debates in the Bundestag (Parliament) into a more general policy debate by combining the decision regarding the provision of German troops to the American-led, so-called “War on Terrorism” in Afghanistan with a vote of confidence with respect to his government, pursuant to Article 68 of the Grundgesetz (GG – Basic Law). With the fate of the Red/Green coalition government hinging on the vote, and the very existence of the Green Party at stake, it was not surprising that Foreign Minister Joschka Fischer (Greens), in his speech on the issue, took a tone more suited for a party convention than for a foreign and security policy debate. And although deploring that posture, most of the opposition speakers followed suit. It was a sad day for German parliamentary democracy. The failure of the Bundestag to live up to its responsibilities is even more apparent in the declarations that accompanied the vote, which show that a considerable number of members of the Bundestag voted for the government in spite of their continuing opposition to the provision of Bundeswehr (German Army) forces, the very conjunction rendered impossible by the use of Article 68. The use of this Article both quashed the existing strong parliamentary backing for the provision of German troops to the anti-terrorism effort in Afghanistan and elsewhere, and denied the Bundestag, and the German public, a serious debate about the first German military operation outside Europe since World War II, excepting the humanitarian contributions to UN missions in Cambodia, East Timor and Somalia.
