First record on size at sexual maturity and optimum catchable length of 10 marine fishes from the Bay of Bengal (Bangladesh) through multi-models approach: a key for sound fisheries management

Size at sexual maturity estimation for 36 species captured by bottom and mid-water trawls from the marine habitat of Balochistan and Sindh in the Arabian Sea, Pakistan, using maximum length (Lmax) and logistic (L50) models

“…In the estimation of L m of fishes using this logistic equation, some studies have reported low accuracy, but its accuracy for short life cycle species is under investigated. However, it was highly prejudiced to use the proportion of Sexual maturity of 36 species in Arabian Sea mature females as an indicator of population reproduction (Mawa et al, 2021). The size at first sexual maturity of fish species might be differed due to feeding rate, sex and gonadal development, behavior, season, flow of water, populations density, water temperature and foods (Hossain et al, 2006(Hossain et al, , 2012Tarkan et al, 2006;Muchlisin et al, 2010).…”

Life‐history traits of Guntea loach, Lepidocephalichthys guntea (Hamilton, 1822) in the Payra River, southern Bangladesh

“…The optimum catchable length (L opt ) is the length above which utmost fishes would be acquired (Froese et al, 2018). L opt assists in selecting mesh sizes of fishing gear and for avoiding the capture of fish underneath the catchable size for the desired fish species (Mawa et al, 2021). Since the present study is also the first research on this biological aspect, no comparisons can be made.…”

Reproductive biology of Heteropneustes fossilis in a wetland ecosystem (Gajner Beel, Bangladesh) in relation to eco-climatic factors: Suggesting a sustainable policy for aquaculture, management and conservation

“…In addition, maturation size of fishes is broadly used as a sign of minimum-allowable capture size ( Lucifora et al, 1999 , Hasan et al, 2021 ). Estimation of spawning/breeding season in fish is essential mainly for the conservation of adult or mature individuals from heavy fishing pressure ( Templeman, 1987 , Mawa et al, 2021 ). The condition factor indicates the level of wellness of the fish in their natural environment.…”
