“…Previous estimations of elasmobranch diversity in Bangladeshi waters have been significantly underestimated (35 to 81 in different studies) [ 34 , 35 , 71 , 74 , 77 , 80 , 83 , 84 , 86 , 91 , 92 ]. By recording artisanal catch, the study has raised the number of reported elasmobranch species in Bangladesh by thirteen.…”

“…Most significantly, they receive limited conservation actions due to data deficiency, lack of community awareness, facilitation in taking sustainable approaches, and finally, resource constraints. Bangladesh remains a conspicuous data gap regarding a comprehensive understanding of its elasmobranch diversity and catches despite being a highly fished region [ 41 , 50 , 70 , 72 – 74 ].…”

Evaluating artisanal fishing of globally threatened sharks and rays in the Bay of Bengal, Bangladesh

Sharks and rays are at risk of extinction globally. This reflects low resilience to increasing fishing pressure, exacerbated by habitat loss, climate change, increasing value in a trade and inadequate information leading to limited conservation actions. Artisanal fisheries in the Bay of Bengal of Bangladesh contribute to the high levels of global fishing pressure on elasmobranchs. However, it is one of the most data-poor regions of the world, and the diversity, occurrence and conservation needs of elasmobranchs in this region have not been adequately assessed. This study evaluated elasmobranch diversity, species composition, catch and trade within the artisanal fisheries to address this critical knowledge gap. Findings show that elasmobranch diversity in Bangladesh has previously been underestimated. In this study, over 160000 individual elasmobranchs were recorded through landing site monitoring, comprising 88 species (30 sharks and 58 rays) within 20 families and 35 genera. Of these, 54 are globally threatened according to the IUCN Red List of Threatened Species, with ten species listed as Critically Endangered and 22 species listed as Endangered. Almost 98% juvenile catch (69–99% for different species) for large species sand a decline in numbers of large individuals were documented, indicating unsustainable fisheries. Several previously common species were rarely landed, indicating potential population declines. The catch pattern showed seasonality and, in some cases, gear specificity. Overall, Bangladesh was found to be a significant contributor to shark and ray catches and trade in the Bay of Bengal region. Effective monitoring was not observed at the landing sites or processing centres, despite 29 species of elasmobranchs being protected by law, many of which were frequently landed. On this basis, a series of recommendations were provided for improving the conservation status of the elasmobranchs in this region. These include the need for improved taxonomic research, enhanced monitoring of elasmobranch stocks, and the highest protection level for threatened taxa. Alongside political will, enhancing national capacity to manage and rebuild elasmobranch stocks, coordinated regional management measures are essential.

This document outlines the importance of the coastal ecosystem, coastal resources, causes of species extinction, techniques to save the endangered species, governmental acts and policies, conservation trends and challenges in Bangladesh. Bangladesh has an extensive maritime boundary blessed with rich coastal and marine ecosystems. Coastal ecosystems have supported human communities for centuries by providing excellent services and influencing human well-being. As the human population of Bangladesh continues to grow, more fish, marine resources and other wildlife species have been put at risk by the loss and fragmentation of critical habitats, climate change, the introduction of non-native species and other environmental factors. Population increases the acceleration of the process of extinction of various marine resources. Out of 57 marine animals, 15 bony fish, 34 cartilaginous fish, five reptiles and three mammals (dolphin and porpoise) are found in the Bay of Bengal under different threatened categories prescribed by IUCN. The government of Bangladesh is aware of the species extinction and has adopted several laws and acts to conserve coastal and marine biodiversity. The success of conservation actions is highly dependent on various stakeholders such as governments, communities, the private sector, and academics. Differences in the interest of these stakeholders often lead to the failure of conservation programs. However, existing comprehensive actions, legislation and improved coordination among government, community, private sector, and academics will be improved significantly to overcome the upcoming conservation challenge.
