“…This could largely be attributed to the short production chain as the catch is immediately sent to main market in the city without any post-harvest processing. A similar situation of male dominance in fisheries is reported from Bangladesh (Islam et al 2013;Galib et al 2016;Shalehin et al 2022). High dependence on fishing perceived as a cause of poverty (Bene 2006) especially when other profitable economic activities were absent.…”

World natural heritage sites (WNH) are those areas recognised for their unique natural resources and/or processes. The main objective of this study was to investigate the living conditions and diversity of livelihoods of coastal communities of the world natural heritage site of the Dungonab Bay-Mukkawar Island Marine National Park (DMNP-WNH). The fishing communities at Dungonab and Mohamed Gol villages were found to be deprived in water, electricity, education, health care, sanitation, flooring, cooking fuel and other livelihood assets. The expenditure of 82.9% of Dungonab and 91.2% of Mohamed Gol households exceeded their income. Accordingly, DMNP-WNH fishers were not able to invest in their livelihood assets and they used hook and line as the sole fishing gear. These conditions have restricted the access of respondents to fishing grounds. About 95% of Dungonab and 93.7% of Mohamed Gol respondents were experiencing extreme poverty. The quality of life at study sites was discouraging for human settlement, therefore, limiting the population growth and consequently the consumption of natural resources at DMNP-WNH. This has positively contributed to the environmental integrity. Access to clean water, electricity and diversification of fishermen livelihoods are of key importance to stimulate blue economy and sustain the environment of the DMNP-WNH.

“…Adverse effects on fishermen's livelihood (e.g. income and fish consumption), a vulnerable community in Bangladesh (Islam et al 2013;Galib et al 2016;Shalehin et al 2022), may be also expected. We recommend further studies to determine impacts of loss of wetland habitats on people's livelihood and biodiversity.…”

Despite positive role of aquaculture in food production, the practice may impact the environment negatively and it is difficult to quantify the loss. In this study, we assessed land use changes in four important wetlands (Hardoho Beel, Angrar Beel, Shaoil Beel and Gopalpur Beel) of Bangladesh through analysis of historical satellite images (1990 – 2020) to show how expansion of aquaculture activities threatens the existence of freshwater wetlands. Since 1990, the water area of all four wetlands decreased significantly over time (all p < 0.001). Mean yearly loss of 47.9 ± 79.3 ha, 99.2 ± 185.5 ha, 51.2 ± 61.9 ha and 2.6 ± 4.7 ha were recorded for Hardoho Beel, Angrar Beel, Shaoil Beel and Gopalpur Beel respectively. A decreasing trend in wetland area was recorded in all wetlands, primarily due to excavation of aquaculture ponds. In 2020, aquaculture ponds represented 72% of the core wetland areas. Two wetlands (Hardoho and Gopalpur) were almost totally lost and converted to aquaculture ponds and agricultural lands. This study concludes that the existence of freshwater wetlands in Bangladesh is at stake and recommends further studies to determine its impacts on people's livelihood and biodiversity.

“…. Respondents Data were collected from fishers, farias (mid-level actor in the distribution channel), commission agents, fish retailers and consumers, the key fisheries stakeholder groups in Bangladesh (Shalehin et al, 2022). Respondents (n = 485; Table 1) were identified at the local fishing sites (fishers and farias) or markets (farias, commission agents, retailers and consumers) randomly.…”

“…Fishery value chains usually consist of multiple groups of stakeholders (Hamilton-Hart and Stringer, 2016;Shalehin et al, 2022). These stakeholder groups may have widespread knowledge of general fish ecology (e.g., Pinto et al, 2013;Braga et al, 2017) but their understanding of threatened species is less clear.…”

IntroductionImproved conservation of exploited freshwater biodiversity is an increasing priority globally, but in developing countries there is often little insight of stakeholder attitudes within the value chains through which exploited species are passed, upon which to make informed management decisions.MethodsWe determined knowledge concerning threatened freshwater fishes in Bangladesh by key stakeholder groups (fishermen, faria agents, commission agents, retailers and consumers; n = 485 respondents) and their participation level in the threatened fish value chain. We also determined factors affecting local ecological knowledge and participation in the value chain.Results and discussionThe highest mean number of threatened fish species (4.8 ± 3.5% of species) was identified by the fishermen group, whereas consumers identified fewest (0.5 ± 1.1% of species). All respondent groups participated in the threatened fish value chain and their participation varied across respondent groups. 45.3% of the total number of threatened fish species appeared in the value chain. Participation level was highest for commission agents, involved in the trade of 21.5 ± 4.2% of threatened fish species, and lowest for consumers (7.4 ± 6.5% of threatened species). For fishermen, the principal component “experience-income-age” and the interaction between education and financial loan factors affected fishers' participation in the threatened fish value chain positively whereas, this was negatively affected by their knowledge level of threatened fishes. This study reveals the poor knowledge of stakeholder groups regarding threatened fishes, but establishes their active participation in the value chain of these species in Bangladesh. With limited resources for conservation of threatened species in many developing countries, it is very risky to implement commonly used in-situ conservation methods (e.g., habitat quality improvement) without fuller buy-in from the stakeholders.ConclusionsWe recommend specific protection laws for threatened fishes and awareness building campaigns for stakeholder groups to ensure minimum impact to threatened fish species. As overharvesting is a major cause of threatened fish species decline, such training programmes should be designed for fishers in developing regions. Education programmes on threats to ecosystems and biodiversity should be prioritized in schools and fishing communities. In addition, regular monitoring for protected species at harvesting sites and fishing markets should be ensured.
