Techno-economic considerations of shark driftnet fishery, off Lagos coast, Nigeria
Experimental fishing operations with driftnets were conducted in Lagos coastal waters with a view to finding out appropriate gear for effective exploitation of sharks and other pelagic fish species that are not normally caught in trawls. The design and fabrication of the driftnets as well as the fishing trials were undertaken between May, 1977 and April, 1978. Six baited driftnet sets of equal panels with three stretched mesh sizes of 190.5mm; 228.6mm and 241.3mm were used. Analysis were carried out on species composition of catches, weight and number of species/group of fish, catch efficiency of the driftnets as well as on operating costs and financial returns
