Abstract
  • This study was conducted between January 2017 to December 2018 in two fishing communities of Bayelsa and Rivers States, Nigeria. The choice of Imibikiri in Brass local government area, of Bayelsa State and Finima in Bonny Island local government, of Rivers State, was based on accessibility, security, fish production intensity, incidental catch of cetacean through drift net fishery. In these community’s artisanal fishery, though rudimentary, constitutes the main stay of the fisher folks. This study investigated catch composition, catch per unit effort during peak and slack seasons as well as the effects of the fishing methods on incidental catches. Their target species are sharks, sail fish and Yellow fin tuna. In this work half dugout boat (Ghana boat) powered by 40 horsepower engines were more efficient in this communities. The total number of cetaceans caught during this period was 315. The economic analysis of this aspect of fishery reveals that in 2017 a kilogram of shark fin goes for N20,000 which is $59.93 at the rate of ($333.71). An assessment of these fisheries operations in the study areas provide useful information on the ways to manage artisanal fisheries for sustainability and the socio-economic problems of artisanal fisher folks.
