Title: Techno economic considerations of shark driftnet fishery off Lagos, Nigeria
Authors: Udolisa, R.E.K.
ASFA Terms: Fishing gear
Issue Date: 10-Nov-1982
Publisher: Lagos: NIOMR
Abstract: 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 driftnet as well as the fishing trails were undertaken b/w May 1977 and April 1978. Nine driftnets of equal panels have three different streched mesh sizes of 190.5mm, 228.3mm respectively. Six of the driftnets were baited while three were unbaited. Analyses were carried out on species composition of catches by weight and number, catch efficiency of the driftnet as well as the operating cost and financial returns.
