“…The histological slides were observed under a compound light microscope (Olympus BX43), and a digitalized camera (Olympus Xcam-Alpha, Germany) was used to capture microphotographs. Furthermore, the classification of various phases of oocyte development in the broodstock ovary was performed according to the method used previously [ 4 , 34 ]. In brief, this study involved the examination of ten ovarian oocytes histological slides from wild and captive broodfish under a light microscope (Olympus BX43).…”

“…Long-whiskered S. aor (Hamilton, 1822) is a large freshwater epibenthic teleost catfish with a wide range of geographical distribution which include Bangladesh, India, Pakistan, Nepal, and Myanmar [ 1 , 2 ]. This fish is a gonochoric species with asynchronous ovarian oocyte development and has several spawning times during the reproductive season [ 3 , 4 ]. Long-whiskered catfish has been deemed among the most favored edible fish due to its rapid growth, excellent flesh quality, low number of intramuscular bones [ 1 , 5 ], and great nutritional value with quality protein content [ 1 , 6 ].…”

“…Therefore, the aquaculture sector requires innovative and sustainable research for the development of hormone-induced breeding strategies to meet the larval requirement of that fish for large-scale industrial development. On the other hand, many previous studies reported that the reproductive performance and oocytes quality in broodstock are influenced by numerous factors, such as housing and tank bottom condition [ 4 ], stress, genetics, nutritional status, egg over-ripening, broodstock age, environmental and water quality factors [ 13 – 16 ].…”

“…Many studies exist on the comparative analysis of wild and captive broodstock reproductive performance [ 10 , 24 , 25 ], biochemical composition [ 10 , 26 – 30 ], amino acid profile [ 26 , 28 ], and ovarian histological investigation [ 4 , 10 ] in different species of fish. However, there is a lack of comparative analysis of reproductive development and tissue biochemical composition in the wild and captive S. aor female broodstock.…”

Long-whiskered catfish Sperata aor is a freshwater catfish known for its supreme flesh quality and fast growth, whose captive-reared broodstock denotes a difficult challenge for aquaculture. The reproductive dysfunctions in long-whiskered catfish raised in tank conditions were observed by comparing tissue biochemical composition and ovarian histology of wild female broodstock. Sixty (60) female broodstocks were used in the current study, consisting of 30 reared at sandy-muddy soil tank bottoms in captive conditions and 30 wild individuals collected from the haor basin during the breeding season. The fish reproductive state was investigated using the biometric and reproductive parameters, biochemical composition and levels of amino acids in the different tissues, and histological analysis of ovarian development. Results revealed that the biometrical parameters of wild and captive female broodstocks exhibited no remarkable difference (p > 0.05). Nevertheless, the wild fish had remarkably higher (p < 0.05) GSI (8.73%), oocyte weight (0.45 mg/egg), and ripeness (27.08%) in comparison with captive-reared broodstock. The total length and body weight, body weight and ovary weight, ovipositor diameter and ovary weight, and GSI and HSI displayed a positive relationship with R2 = 1, R2 = 1, R2 = 0.993, and R2 = 0.973, respectively, for wild broodstock, while R2 = 0.994, R2 = 0.806, R2 = 0.804, and R2 = 0.896, respectively, for captive broodstock. Additionally, the proximate composition in oocytes and liver tissues in both broodstocks did not differ significantly (p > 0.05). However, two essential amino acids (EAA), i.e., lysine and phenylalanine, and two non-essential amino acids, i.e., glutamic acid and glycine, were highly significant differences (p < 0.05) in the oocytes and liver of wild broodstock compared to the captive-reared broodstock. On the other hand, the EAA, e.g., isoleucine, threonine, leucine, and arginine, were highly dominated in both wild and captive female brood oocytes and liver. The ovarian histological slides from each fish group showed three oocytes developmental stages that indicated the asynchronous-reproductive ovarian oocytes of this fish. This study may be useful to fully understand the factors affecting the spawning and reproduction of S. aor broodstock, crucial for management in captive conditions as well as conservation and protection for sustainable aquaculture management of S. aor.

“…Bangladesh is the ground for many diverse and complex wetland ecosystem comprising with Beels (big depressions where water remains yearlong), seasonal wetlands (Oxbow lakes), Haors (large deeply flooded depressions), Rivers, Streams and vast seasonally inundated floodplains which are rich as well as possess global significance (Dutta et al 2021;Sumon et al 2022). Bangladesh floodplains are one of the world"s most important wetlands and support about 70 million rural households, including the very poorest which are critically dependent on wetlands (Sultana and Thompson 2017).…”

The diversified and complex wetland ecosystem in Bangladesh has global significance for the concern of many environmental issues. A study of two wetlands in northeastern Bangladesh examines the different outcomes produced by community-based management (co-management) and private management. The data and outcomes of the private management systems generated in the Kawadighi Haor were compared with those of the Hail Haor, where comanagement had been adopted. The results strongly indicated that, in comparison to the private management system, water bodies under comanagement adopt more ecological management approaches, resulting in greater sustainability of resources and a more equitable distribution of benefits. The National Wetland Policy (2009) in practice promotes a traditional shortterm leasing model that is highly susceptible to elite capture. The study also found that the biophysical condition and ecology of the Balla beel of Hail Haor were in decline before co-management began, then rapidly recovered during the co-management period, and quickly declined again when private management took control over the waterbody. The study further provides a set of recommendations for the sustainable management of wetland resources in Bangladesh and in a broader global context.
