Climate Change Impacts on a Tropical Fishery Ecosystem: Implications and Societal Responses

The present study aimed to map out the current threats and anticipated impacts of climate change on the most important hilsa shad (Tenualosa ilisha) fishery and the associated fishing communities based on fieldwork in six coastal fishing communities. To collect empirical data, individual interviews, focus group discussions, oral history, and key informant interviews were conducted. To supplement the empirical findings, time-series data of cyclones and sea-borne depressions in the Bay of Bengal were also analyzed. Analysis of secondary data regarding climate change-induced events and regional studies suggested that the biophysical conditions of the Bay of Bengal are likely to be aggravated in the future, potentially causing more frequent extreme events and affecting the livelihoods of coastal fishing communities in Bangladesh. The fisher respondents revealed that the main target hilsa shad fishery is particularly vulnerable to climate change in terms of alterations to migration patterns and breeding and growth performance. The fishers reported constant climate-related risks because they live in seafront locations, exposed to extreme events, and their occupation entails risky sea fishing. Fishers claimed that they often need return to the coast due to unsuitable weather conditions related to cyclones and frequent tropical depressions, which can cause financial losses or even causalities. Such events negatively affect fishers’ livelihoods, and wellbeing. To cope with the impacts of climate change the fishers have adopted various strategies at both sea fishing and household levels. However, these strategies only support the fishers in terms of immediate survival; they are not enough for long-term resilience. To improve the resilience of the hilsa fishers, the study argues for the implementation the Small-Scale Fisheries Guidelines (SSF Guidelines), which call for longer-term development goals, including in the immediate relief phase, and rehabilitation, reconstruction, and recovery to reduce vulnerabilities to climate and anthropogenic risks

Assessing Fisheries Policies of Bangladesh: Need for Consistency or Transformation?

With the aim to enhance production, alleviate poverty, meet animal protein demand, earn foreign currency and maintain ecological balance, the Bangladesh government has formulated the National Fisheries Policy 1998. Over the last two decades, this policy for safeguarding fisheries is still in practice but gets little attention by researchers and policy makers to assess its effectiveness. This study analyzes the fisheries policy frameworks and evaluates how policy changes affecting fisheries production with certain ecological balance. The paper describes elements in the historical process of the development of the national fisheries policy related to the issue of equal or restricted access to the fish resource. The findings suggest that changes in policy only could not offer solutions to prevent over exploitation and overcapitalization that presently exists in conventional open access fishery. In addition, key constraints underlying in between policies and in implementation of laws includes ignorance of conservation laws, overwhelmingly top-down decision-making, lack of appropriate policy goals, inadequate enforcement, outdated policy and bogus action strategy, lack of enforcement regulations against pollution, poor coordination and technical know-how of the personnel concerned. For achieving inclusive growth in the fisheries sector, the UN Sustainable Development Goals and the government stated the Vision 2021, fisheries policy reform is recommended with special emphasis on marine fisheries sub section formulation, socio-economic development of relevant communities, updating of existing governance, and strengthening institutional capacity to appropriately manage this potential sector. Moreover, the existing regulations should be amended accordingly with clearly defined reliable enforcement authority

Coastal Ecosystem Services, Social Equity, and Blue Growth: A Case Study from South-Eastern Bangladesh

By employing empirical and secondary data (qualitative and quantitative), this study demonstrates how social equity (with its three dimensions) can meaningfully address the conservation of the coastal social–ecological system (SES), without losing diverse ecosystem services (ES) in south-east coastal Bangladesh. Based on this proposition, this study assesses the available ES and identifies the drivers responsible for ES changes, arguing for the application of social equity for resource conservation. The findings show that communities along Bangladesh’s south-eastern coast use several ES for food, medicine, income, livelihoods, and cultural heritage. However, this valuable ecosystem is currently experiencing numerous threats and stressors of anthropogenic and natural origin. In particular, large-scale development activities, driven by the blue growth agenda, and neoliberalism policy, pose a risk to the local communities by degrading coastal ecosystem services. Escaping this situation for coastal natural resource-dependent communities in Bangladesh will require a transformation in the governance structure. Implementing the Small-Scale Fisheries (SSF) Guidelines that call for initiating policy change to deliver social justice to small-scale fisheries would help to address coastal ecosystem service conservation in Bangladesh

Application of Length-Based Assessment Methods to Elucidate Biological Reference Points of Black Pomfret Stock in the Bay of Bengal, Bangladesh

The black pomfret (Parastromateus niger) is one of the high-income-generating carangid fish species and the only known member of its genus. This study aims to identify existing gaps in stock status and population demography of this species and provide viable management recommendations to enhance the sustainability of this fishery. Therefore, three methodological approaches have been used in this study; TropFishR to present the current exploitation status, the length-based spawning potential ratio (LB-SPR) to quantify stock spawning biomass, and Froese’s sustainability indicators (LBI) to establish a basic standard for sustainable management of the fishery. In the length-weight relationship of black pomfret, an allometric growth pattern (b = 2.19) was found. The VBGF life history parameters for black pomfret were L∞ = 55.25 cm, K = 0.54 year−1, and based on LCCC analysis, the total mortality (Z = 1.61 year−1), natural mortality (M = 0.69 year−1) and fishing mortality (F = 0.91 year−1) are calculated. The result reveals that this fishery is currently suffering from overexploitation and the stock’s spawning biomass (SPR = 13%) is below the limit reference point because most of the catch (82%) was found to be under the maturity level. Based on the results, this study recommended strictly maintaining the mesh size of the net to ensure not to catch immature fish with a length smaller than 30.63 cm, recommended the length to catch be between 29 and 35 cm, and reducing fishing pressure by one-third to ensure the sustainability of the black pomfret fishery

Fisheries-Based Ecotourism in Bangladesh: Potentials and Challenges

Recreational fishing trips constitute a significant part of the tourism business in many countries. Linking fisheries to tourism can be both a response to the need to create innovative tourism products and the need to find new sources of income for fisheries to make them more profitable and sustainable. This leads to the question of whether Bangladesh can be developed as a Fisheries-Based Ecotourism (FbE) destination. Though several types of research have been done concerning the prospects of ecotourism in Bangladesh, the feasibility of FbE specifically remains under-studied. Based on a literature review and stakeholder interviews, this study explores the concept of FbE in a Bangladeshi context and its potential impacts on socio-economic community life as well as on the environment. This paper makes the case that the diversified topography of Bangladesh—including the riverine flat alluvial plains, hills and valleys, deciduous and evergreen forests, lakes, seashores, and beaches—is ripe with potential for FbE development. With its focus on the prospects and challenges of FbE development in Bangladesh, this paper could provide a useful reference point for future discourse on these sorts of cultural and economic strategies

Ocean governance in Bangladesh: Necessities to implement structure, policy guidelines, and actions for ocean and coastal management

After the permanent demarcation of Exclusive Economic Zone boundaries with Myanmar and India through the International Tribunal for the Law of the Sea and the United Nations Convention on the Law of the Sea, Bangladesh has exclusive rights to exploit and to explore marine resources across 118,813 km(2) in the Bay of Bengal. To reap economic benefits from maritime space, the government of Bangladesh recently emphasized the development of a blue economy. Maritime economic activities, including shipping, trade, fishing, fishing industries, mineral extraction, exploitation of hydrocarbons, salt production, production of renewable energy, and marine and coastal tourism, are key elements of the maritime interests of policymakers. However, the safety of maritime activities also raises concerns that include shipping accidents, smuggling, and illegal fishing, which pose threats to maritime interests. Enhancing blue economic growth and protecting marine and coastal environments are essential to ensure maritime security. Therefore, in the framework of a comprehensive ocean governance approach, we suggest establishing a separate Ministry of Ocean Affairs with essential functions to formulate an integrated coastal and marine strategy, to address the policy guidelines, and to implement action plans for coastal management in Bangladesh.

Fishery-Based Ecotourism in Developing Countries Can Enhance the Social-Ecological Resilience of Coastal Fishers—A Case Study of Bangladesh

The importance of recreational fishing, in many coastal areas and less developed nations, is increasing rapidly. Connecting fisheries to tourism can create innovative tourism products and provide new income sources. The present study is the first to explore the concept of coastal fishery-based ecotourism (FbE) to enhance the social–ecological resilience of coastal fishing communities in a specific tourist spot in Bangladesh. A combination of primary (quantitative and qualitative) and secondary (literature databases) data sources were used in this study. It applied a social–ecological system (SES) and social–ecological resilience (SER) concept to collect quantitative and qualitative data (120 in-depth individual interviews, four focus group discussions, and strengths, weakness, opportunities, and threats-SWOT analyses) and frame their interpretation. The study found that Bangladesh needs to adopt a firm policy to utilize tourism’s potential in national economic development and societal progress. The findings show the considerable potential of the concept that integrates business, education, and an environmental conservation perspective in Bangladesh, specifically for Saint Martin’s Island: 32% of interviewees expressed that increasing employment opportunities and the Gross Domestic Products (GDP) is the primary potential, whereas 31% said it would attract fishing tourists and 23% believed it would develop the local infrastructure and facilities for fishing and tourism. Similarly, most of the respondents (31%) thought that the lack of awareness and promotional activities is the main limitation preventing this initiative from being well accepted. Moreover, based on the findings, specific measures for strengthening the social–ecological resilience of the coastal fishers via FbE at the local level were suggested, including building communal links, developing community infrastructures, revising prevailing rules and regulations, offering alternative means of generating income for fishers during disaster periods, and more active sharing of responsibility between stakeholders and government for the management of FbE. Finally, with its focus on the prospects and challenges of coastal FbE development on Saint Martin’s Island, this article provides a useful reference point for future discourse on similar social and economic strategies. While this study focuses on Bangladesh’s coastal fishing villages, the results are possibly applicable more broadly in similar contexts and developing countries worldwide

Mud crab (Scylla serrata Forsskal 1775) value chain analysis in the Khulna region of Bangladesh

Publisher Copyright: © 2021 Shanghai Ocean UniversityA value chain analysis is a detailed description of all the activities and services needed to turn a raw product into a marketable good for delivery to final consumers. The mud crab business is considered by most marketing operators to be a profitable and viable business due to the high demand in the international market. Despite the importance of mud crab fishery, there is no structured marketing facilities in Bangladesh. This research aim to analyze the socioeconomic condition of actors, the profitability of farming, mapping the institutional and non-institutional barriers, and provide a better understanding of the possibility of technological interventions in the value chain. Qualitative and quantitative data were collected through participatory rural appraisal tools that include 200 individual interviews, 16 focus group discussions, and 24 key informant interviews conducted in south-west Bangladesh from July to December of 2019. The mud crab value chain analysis revealed that the chain started with crab collection (cultivated and wild harvest), before sale to local vendors, and ended with exporters through several intermediaries. Results noted that most (±95%) exportable crab came from natural sources, with rest (±5%) from aquaculture sector. The average price (USD/kg) ranged from $10.59−14.12 and$12.94−19.42 for male crabs (grade: XXL), followed by $10.00−11.77 and$11.77−17.06 for female (grade: FF1) in domestic and international markets, respectively. Despite the high profitability of these sectors, the livelihood of these stakeholders has remained relatively hard. Multi-pronged approaches, like a nursery or increasing farming and backyard seed production, and possible value addition at the farm level may help farmers.Peer reviewe
