Length-weight relationships of five fish species in Epe lagoon, Nigeria

Length-weight relationship (LWR) of 320 fish populations covering 3 families, 4 genera and 5 species inhabiting Epe Lagoon, were studied. The fishes ( Clarias gariepinus (Burch), Illisha africana Bloch ), Chrysichthys nigrodigitatus (Lacepede), Chrysichthys walkeri (Gunther) and Ethmalosa fimbriata (Bowdich)) were obtained from fish landing site at Epe market from November 2001 to October 2002, and January to December 2003. The parameters a and b of the length-weight relationship of the form W=aL b and condition factor (c.f.)=W100/L 3 are presented for the five fish species. The c.f. values significantly (P African Journal of Biotechnology Vol. 4 (7), pp. 749-751, 2005
