A Novel Body Mass Index (sfbmi) Approach To Fish Health Assessment In Fisheries And Aquaculture: Prototype Framework And Species-specific Considerations
Assessing the health and condition of fish is essential in Fisheries and Aquaculture, as it reflects nutritional status, ecological well-being, and environmental quality. Traditional indices such as Fulton’s condition factor (K) and relative condition factor (Kn) have been widely used by fisheries scientists and environmentalists. Still, these often assume...

Jaw Tags Do Not Impact Adult Rainbow Trout Oncorhynchus Mykiss (walbaum, 1792) Growth Or Physiology
Metal tags secured to the jaw of fish have long been used in fisheries management to collect data on fish behavior and growth. This study was undertaken to evaluate the possible effects of these jaw tags on relatively large rainbow trout Oncorhynchus mykiss growth and physiology. A total of 160 rainbow trout, initial weight 1134 ± 19 g (mean ± SE)... Continue here
Effect Of Sex Reversal Hormone (17ᾳ-methyltestosterone) On Growth Performance And Survival Rates Of Heterobranchus Longifilis Fry
The study aimed at determining the effect of sex reversal hormone (17α-methyltestosterone) on the growth performance and survival rate of Heterobranchus longifilis. The experiment consisted of five treatments replicated three times in a completely randomised design. Mature and gravid broodstocks of H. longifilis were purchased and bred in the laboratory...

Assessing Sustainable Fishing Strategies In Nigeria’s Artisanal Fisheries
Artisanal fisheries are vital to Nigeria’s food security, livelihoods, and socio-economic stability, supplying over 80% of domestic fish and employing millions across coastal and inland communities. Despite their importance, the sector faces significant challenges, including overfishing, weak governance, climate change, pollution, and limited adherence to... Continue here
