Abstract:Gillnet selectivity of Coptodon zillii was estimated in this study to determine the appropriate mesh size for the exploitation of the fish in Asejire dam. Holt’s indirect method of estimation was used to estimate gillnet selectivity of C. zillii in Asejire dam. Three mesh sizes 50.8mm, 63.5mm and 76.2mm were used for the estimation. The result shows that these mesh sizes caught C. zillii that were significantly different in sizes and abundant (P < 0.05). The 63.5 mm mesh size of gillnet was the most efficie… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
