<p>The potential of fisheries resources is still massive as well as the challenges.  One of the challenges faced in the fisheries sector is climate change occurring massively. Climate change that occurs disrupts the productivity and activities of fishermen. Fishermen live with uncertainty because their livelihoods are directly related to nature. So that fishermen are required to be able to adapt and mitigate to climate change that is occurring rapidly. Information innovation and communication are widely developed to help fishermen in sea activities. The technology created is available in various forms, such as android-based applications, SMS broadcasts, Whatsapp groups, GPS, Fishfinder, etc. The objective of this study is to identify fishermen's perception of the benefits of technology and service communication used, ICT relationship with fishermen's income, and stakeholder role strategies in the use of ICT. The mix-method approach is used to acknowledge study objectives using the software SPSS 23 and Atlas. Ti 8. The result shows that fishermen's perception of the benefits of ICT namely facilitating communication, reducing production costs, improving safety, increasing fishermen's knowledge, and increasing income. There is a relationship between the use of ICT and fishermen's income, as well as stakeholders who have an important role in the use of ICT in the fishing community.</p>

Co-management has been promoted as an alternative approach to the governance of small-scale inland fisheries resources and has been implemented in many African countries. It has, however, not proven to be a simple solution to improve their governance; hence, most African inland fisheries are still experiencing unsustainable overexploitation of their resources. As such, there is a need for reassessing the application of governance strategies for co-management that should strive to strengthen the participation of stakeholders, primarily the local fishers, as they are fundamental in the governance of fisheries resources. Therefore, this study set out to explore the prospects of a co-management governance approach at a Lake Itezhi-Tezhi small-scale fishery in Zambia. Focus group discussions with fishers and semi-structured interviews with other stakeholders were used to collect data. This study revealed that the stakeholders perceive co-management as a feasible approach to governance of the Lake Itezhi-Tezhi fishery. However, the feasibility of the co-management arrangement would be dependent mostly on the stakeholders’ ability to address most of the ‘key conditions’ criteria highlighted in the study. This study also identified the need to establish a fisheries policy to provide guidelines for the co-management, coming with decentralisation of power and authority to the local fishers.

This study considers the Old Brahmaputra River, Bangladesh, as a case study regarding community perceptions on urban pollution and its impact on rural communities. In doing so, in-depth individual interviews (n = 195), key informant interviews (n = 7), and focus group discussions (n = 7) were conducted by emphasizing different perspectives on urban pollution and its effects on people related to losses of fisheries resources, agricultural production, human health, and livelihood transformation. The findings illustrate that poor urban solid waste management and direct sewage discharge degrade rivers daily. The most vulnerable rural communities are directly dependent upon the river, including fishermen, farmers, and boatmen. Specific measures such as an effluent treatment plant should be established near the river, and households and commercial drains should be cut off from the direct connection with the river. Alternative income-generating activities for the stakeholders are suggested to safeguard the river from urban pollution and the wellbeing of the stakeholders.

Bagarius bagarius (Hamilton, 1822) is widely distributed in South and Southeast Asian countries, including Bangladesh. This species is economically important as a game and food fish. The abundance of this fish is declining around the world, especially in Bangladesh, due to a variety of meteorological and mostly anthropogenic factors, which is potentially generating concern among the conservationists. Therefore, this species has already been declared a critically endangered species by IUCN Bangladesh. Although there is no specific conservation initiative for B. bagarius in Bangladesh, various measures are there to conserve fisheries resources, which may have an impact on conserving B. bagarius in this country. This study reviews the biology and ecology with its distribution throughout the country as well as the world, threats, conservation measures, and finds out the gaps in research on this fish. Moreover, this review suggests a suitable conservation framework to improve the conservation strategy for this critically endangered fish that can be replicated in other countries for the same purpose.

While pressure on marine ecosystems leading to declines in global fish catches have been attributed to excessive fishing and to unregulated and unreported fishing, existing management practices have yet to fully address these declines. Estimation of spatial and temporal distribution of fisheries resources and the extent of fishing impacts on marine ecosystems using vessel trajectories has become central in recent studies. This study proposed the use of trajectories of 771 Korean coastal and offshore fishing vessels and one-year fish landing data to estimate variations in commercial fish species, vessel, and fishing gear activity distributions in the waters around Jeju island. A set of standards were applied to identify individual fishing tracks of major gears and uniformly distributed catch to fishing segments of trajectories to produce spatio-temporal distributions of catch, fishing activities, and vessel reliance on fishing grounds at a fine spatial scale. The method identified reference points that can inform management at local and regional scales. We discuss the opportunities of combining larger datasets collected over a longer period and applying predictive modeling techniques in making extensive assessments, including climate change impacts on fishing activities that can inform resource management and marine spatial planning.

<p>In the Pacific, customary marine tenure-ship and management has been practised for centuries. Community based marine resource management (CBMRM) initiatives have seen governments, local communities and non-government organisations adopt various management tools to improve coastal fisheries. Despite these efforts, there are growing concerns over the decline of fisheries resources and the subsequent social-ecological problems that affect coastal communities.  In the last three decades, Fiji, has implemented various forms of CBMRM initiatives with varying social-ecological successes. Marine management and conservation efforts across the 410 qoliqoli areas (fishing grounds) are predominantly driven by Indigenous Taukei communities and non-government conservation organisations (NGOs). Over the past two years local communities, NGOs, and government have led and supported new management efforts to improve fisheries sustainability in the country.  Non-Indigenous resource users are limited by social and political policies to access and participate in coastal resource management. Fijians of Indian descent (Indo-Fijians) represent the second-largest ethnic group in Fiji and are engaged in both subsistence and artisanal fisheries. Their involvement and participation within the broader socio- economic and socio-political aspects of coastal fisheries is considerable, however, remains hidden. Using a qualitative approach, this study explores the issues, challenges, and opportunities that Indo-Fijian communities experience in the coastal fisheries sector in Ba Province, Fiji.  Findings from the research illustrate the informal yet complex nature of socio-economic and socio-cultural community relationships between customary Taukei qoliqoli owners and Indo-Fijian people. The role of Indo-Fijian women within the coastal fisheries sector is notable. The success of contemporary CBRMN in Fiji is dependent upon a re- imagined, re-adapted, diverse approach. Most importantly, this research provides an opportunity to foster discussion within contemporary community based marine management and conservation efforts currently in place by customary Taukei qoliqoli owners, conservation organisations and the government.</p>

Fisheries conflict is an underappreciated threat to the stability and health of communities. Declining fish populations, rising demand for seafood, and efforts to reduce illegal fishing are increasing the risk that conflict over fisheries resources will undermine stability and peace. Here, we investigate the frequency, causes, and consequences of fisheries conflict in six countries around the Horn of Africa and East Africa (Tanzania, Kenya, Somalia, Djibouti, Eritrea, and Yemen) between 1990 and 2017. Fisheries conflict events were cataloged from news reports, and events were characterized by the date, location, actors, consequences, and drivers of the conflict. We found the rate of fisheries conflict is gradually increasing in the region, with spikes in conflict driven by the arrival of foreign fishing boats or international naval vessels. Conflict was caused primarily by illegal fishing, foreign fishing, weak governance, limits on access to fishing grounds, and criminal activities including piracy. Two-thirds of all conflict events occurred in Kenyan and Somali waters, with areas of high conflict intensity in the Lake Victoria region, near the Somali coastline, and in the southern Red Sea. During this period, 684 fisheries conflict events in the region resulted in over 400 fatalities, nearly 500 injuries, and over 4,000 arrests.

Ichthyoplankton is the cluster of planktonic organisms that consists of fish eggs and larvae. These planktonic stages belong to the temporary zooplankton, representing future exploitable stocks. The study of the early ontogenesis of fish plays a key role in the understanding and evaluation of these populations through the study of their abundance and their spatio-temporal distribution. To better understand and protect these fisheries resources, it is essential to identify the different stages of fish embryonic development. This identification is usually performed using the classical method, based on morphological criteria under a binocular magnifying glass; however, this methodology is not always sufficient and is time consuming and, therefore, it is necessary to rely increasingly on molecular tools. The major problem with these tools is the yield and quality of the nucleic acids extracted from ichthyoplankton, especially in the case of eggs, which are small. Several methods have been used for DNA extraction from ichthyoplankton, either automated or manual, but very often from larvae or adults. In the present work, five fish egg DNA extraction protocols were compared based on their DNA yield and extraction quality, verified by agarose gel electrophoresis and quantitative PCR amplification. The results showed that extraction by our heat-protocol for direct PCR (Hp-dPCR) presents the simplest and cheapest protocol of all the kits used in this study, providing a sufficient quantity and quality of nucleic acids to be used for PCR amplification, and being within the reach of third world laboratories that often do not have sufficiently large budgets to obtain automated kits.

Abstract Southwest Sumba water is part of the Indonesian fisheries management region (WPP573). Marine fisheries resources are influenced by oceanographic phenomena such as an upwelling event. This study aims to describe characteristics of seasonal Ekman upwelling by analyzing oceanographic parameters from the validated INDESO model output (2008-2014). It shows that upwelling event in the study area occurs during the Southeast Monsoon period, which creates an Ekman drift of 0.26 Sv towards offshore. This transported water mass is then replaced by an upwelled vertical flow of sub-surface colder and nutrient-rich water at the velocity of the order of 10−4 m/s. Surface features of the upwelling event are seen from a minimum temperature (24.3 °C), sea level anomaly (0.34 m), but the maximum of chlorophyll-a (3.02 mg/m3). During this time, an uplifted isotherm of 25.5 °C is found from sub-surface to 10 m depth, but it is outcropped at the sea surface in the centre of upwelling area. Interestingly, during upwelling event, salinity stratification revealed an isohaline of 34.10 psu is much deeper at 40 m depth, and much fresher water mass from the Ombai Indonesian Throughflow water is dominant. Averaged temperature-based upwelling index between June-September is about 0.3 °C.
