Description:
A 14-day quick appraisal fisheries survey of the Brass River area was conducted from 8th-21st June 2005 to collect information on fish species, fish catch and fishing craft. Total fish catch was estimated to be 11,086.12kg. Out of a total of 15 families and 43 species caught in the area, the Sciaenidae (Pseudotolithus typus, P.elongatus, P.senegalenensis) contributed 37%, the Polynemidae (Polydactylus quadrifilis) 26%, and Bagridae (Chrysichtyes nigrodigitatus) accounted for 17% of the total fish landings. The landings at the Coastal Marine Waters were about 66 % while the catch from gill nets constituted 68% of the total fish landings, followed by traps with 15%, hooks and lines landed 11 % while seine nets and cast nets contributed 5% and 1 % respectively to total fish landings. Four types of crafts were used in the Brass River Fisheries including the Ghana boat, plank boat (with or without engine), fiberglass speed boat and the dug-out canoe. In view of high industrial and commercial activities and especially threats from oil and gas pollution, it is recommended that the fisheries of the Brass area be properly investigated.
