Assessment of the capture efficiency of the artisanal fishing gears employed at upper Benue Basin, Nigeria


Author(s): Amadu SO

Abstract: The study was carried out to assess the capture efficiency of the artisanal fishing gears employed at Mayo Ranewo and Lau fishing point of the Upper Benue Basin, Nigeria. Water samples were collected the fishing points twice monthly and subjected to physicochemical parameters analysis. Sampling of gear types and fishes captured by the gears was by direct observation. Coefficient of Variation was used for the assessment of variability in the Catch Per Unit Effort (CPUE) by gear types. The mean water temperature recorded is 25.375. The water pH of the water from the dam were most basic (pH = 6.2). Transparency was 0.730. Dissolved Oxygen levels is 3.82mg/L. Alkalinity level is 571.8mg/L while Conductivity is 438.84μmhos/cm, Ammonia level is 0.032mg/L while CO2 level is 5.20mg/L. A total of 5 different gear types were identified to include: Malian trap – Gura/Malia; Longline – Rincha; Gill net –Taru; Lift net – Akauji; Cast net – Birgi. The result further indicated that Coefficient of Variations (C.V) differ with the gear used. The study therefore recommends that further investigation on the efficiency of the nets over a longer period (for at least 2 seasons) should be carried out.
