“…It has also been noted that artisanal fishermen are more likely to be the worst affected as many (if not all) count on this as their livelihood source. This observation is compatible with that of [5], [26].…”

“…On the other hand, wetlands provide multiple multidimensional services within their environment, such as water purification, supporting natural resources that provide essential human and animal resources. Wetlands also offer multifunctions such as flood control, and water pollution, waste water treatment, farming activities and providing fishing ground sites with opportunities for fishing and sailing events [1], [5]. Wetlands offer people residing inside and around the buffer zone a chance to improve their livelihood [6].…”

Fisheries and aquaculture plays a significant role in the Nigerian economy by providing employment, diversifying livelihoods, providing animal nutrition, and earning returns on foreign exchange. Fish is an important economic factor for many nations, as serves as a staple diet in many countries. As evident, in many developed nations, fishing is a crucial source of livelihood, particularly for low-income families in rural areas, where it offer local jobs in many communities and is a key source of food for millions. Over the past few decades, fish populations have deteriorated dramatically, and species at risk have experienced growing environmental challenges. Dams, overfishing, pollution, erosion, soil loss and other human activities are main threats to fisheries ecology. The presents study aimed to analyze the decline in diversity of the fish, adaptive management of artisanal fishermen in the wetlands of Hadejia-Nguru, Guri local government area of Jigawa State and to explore the correlation of environmental factors for the decline in fish diversity. In this study the data were collected through questionnaire interview (QI), focus group conversation (FGD), and field data collection (FDC), and the test objectives were accomplished via the analysis workflow. Geostatistical software was used to analyze the information obtained from QI, FGD and other sources while other auxiliary data and field data were collected using GPS receiver. The research findings can be considered as a tools for decision-making, policy-making, management plan development, fish conservation strategies plan and ultimately help to achieve the UN's Sustainable Development Goals (SDGs) 1, 2, 8, 14 and 15 of the 2030 agenda.

One of the largest wetlands in Bangladesh's north‐east, Hail Haor supports a variety of aquatic habitats and has a diversified ecosystem. To ascertain the fish diversity indices of Hail Haor, this study was carried out month by month from December 2020 to June 2021. For this study, three sampling sites in the Moulvi Bazar district—Chiruadobi Beel, Gopla River and Balla Beel were chosen from which fish samples were collected. Twenty‐five different fish species were identified and 12,076 fish (individual numbers) were counted and categorized. The Shannon diversity index varied from 1.33 to 1.65. Hail Haor's species diversity index is moderate by the index standard. The Shannon evenness index (E) varied from .41 to .51. The Depressed Community is present in the Hail Haor species diversity index, as per the index standard. The Simpson dominance index fluctuated from .56 to .72. The species diversity index of Hail Haor contains moderate dominance, as per the index standard. With the help of local retailers, fishers, and other relevant stakeholders, the FGD identified factors that have an impact on the diversity index. The current study on diversity indices will be highly beneficial for formulating strategy and managing Hail Haor by strictly adhering to the recommendations.
