Small-Scale Fisheries in Lagos State, Nigeria: Sustainable Yield Determination

By O.O. Jinadu

ABSTRACT

The objective of the study was to determine the seasonal sustainable yields of the small-scale fisheries in Lagos State of Nigeria. Between January and December, 113 mechanized and 43 non-mechanized small-scale fishing units in 21 purposively chosen coastal villages were surveyed on a bi-monthly basis through questionnaire administration. Input and output data collected included the physical variable inputs and the landings of five fish families of prime economic importance, namely: Sciaenidae, Ariidae, Polynemidae, Clupeidae and Carangidae. Multiple linear regression and Cobb-Douglas technique were employed to determine the physical sustainable yield of the fish families by the mechanized and non-mechanized categories.

The economies of scale for the two categories in the two seasons were positive, meaning that there were possibilities of increased production by the artisanal fishing fleet evaluated with some external intervention. The advantages of outboard engine ownership showed during the study. It was therefore proposed that the Lagos State Government should rejuvenate the defunct subsidy scheme to optimize the future catches and the fishing operators advised to adopt the reinforced fiberglass boat for easier beach launching and landing in areas where surf conditions are heavy and dangerous. Other policy measures considered were those that could stimulate investments into the fisheries so that fishing operations will on the long run be optimal.
