Abstract: We investigated the incidences of juvenile fishing according to fishing practices in Freetown peninsular. Theindustrial trawl fishing sector, despite its technology is not fully selective to avoid by-catch of juvenile fish, andartisanal fishing is so less for economic reasons. Ineffective enforcement of fishing regulations is a major cause tothe catch of both targeted and non-targeted juvenile fish. We collected data on the quantity of juvenile fish and thedaily duration of fishing trips in four landing sites over a two-week period Bernoulli random variables and propertiesof uniform distribution were used to analyze the data. Catch rates of juveniles Ethamatosa fimbriata, Sardinellamaderensis, and Brachydeuterus auritus around the Freetown peninsular were 170.8, 212.4 and 194.60 kg per hourper day, respectively. This rate revealed that the current trend of juvenile fish landings is a threat to thesustainability of fishery capital, revenue, and biodiversity.
