Inventory and Impact of Dominant Fishing Gear and Method in Eleyele Lake Oyo State, Nigeria | Chapter 11 | Current Perspectives to Environment and Climate Change Vol. 2
Gill nets fishery are potentially selective and therefore use as a sampling gear if mesh sizes are rightly chosen in order to conserve the young and developing fishes. The fishing potential of derelict passive gill net poses irreversible and economic loss on the aquatic ecosystem and fishermen respectively. There by contributing to biological assets loss and capable of causing navigational hazard. Precautionary approach towards Conserving and sustaining renewable aquatic resources is the best for exploitation of the cheapest sources of animal protein in sub-Sahara region. This paper gives inventory of the existing fishing gears and methods commonly in use, impacts of gill net fishery in terms of mesh sizes selectivity, catch per unit effort, fishing profitability index in Eleyele Lake Ibadan and artificial fish aggregating device potential of derelict gill net in Oyo State resident Waters . A total of 539 fishing gears were encountered in six sampled areas of two strata; gill n...
