    abstract = {One year (January,  December, 1999) length-frequency data sampled from catches of five randomly selected artisanal fishers that use unmotorized canoe were analyzed using FiSAT (FAO-ICLARM Fish Stock Assessment Tool) to obtain exploitation ratio of eleven fish species. Under exploitation was evident in 27.30% cases (3fish species) viz, Galeoides decadactylus: E (exploitation ratio) was O. 2000; Chrysichthys nigrodigitatus (E = O.2500) and Sarotherodon melanotheron (E = 0.5240). In 63.70% cases i.e. seven species namely Ethmalosa fimbriata (E = 0.5240); Eucinostomus melanopterus (E = 0.4589); Ilisha africana (E = 0.5540) Liza grandisquamis (E = 0.4560), Lutjanus goreensis (E = 0.740), Pomadasys jubelini (E = 0.5290) and Tilapia guinensis (E = 0.4820) the fishery can be described as being under optimum exploitation. Only Pseudotolithus elongatus (9%) is overfished. Conservation strategies include establishment of grow out brackish water fish ponds, propagation by natural seeds, control of pollution and environmental degradation.}
