Nigeria institute for oceanogaphy and marine research annual report 1997.
Few publications on the Fisheries of Nigeria focus on the non-penaeid decapod stocks, and in general, reports discussing artisanal coastal and estuarine shrimp landings have been based largely on ad-hoc observations. Presumably as a consequence, only the big penaeid Penaeus notialis and Parapenaeopsis atlantica are identified, and that, only occasionally. More often than not, artisanal crustacean catches are usually lumped together as if they consist of a single taxon and treated under such group name as Caridae. The exception is that of Scott (1966) who estimated 1125 tons as the annual landings of filter traps fishing in the Bonny River to Forcados area, about 40kg per man per day. Tracing the abundance of white shrimp Nematopalaemon hastatus, Marioghae (1980) recorded catch per trip for filter traps ‘Iseke’ and Stow nets ‘Nkoto’ as 1.25 and 6.67 kg respectively. Enin et al (1989) examined shrimp seasonality in the stow net Nkoto trap fishery in Cross River Estuary. But seaso.....
