Abstract: The growth characteristics of Selene dorsalis in Forcados River estuary, Delta State, Nigeria was studied from April 2012 to March, 2014. The Length-weight relationship (LWR) of the fish was evaluated using the equation: W = a Lb while determine the condition factor of the fish using the equation; K a= 100W Lb. The intercept (a) ranged from 1.74-1.82 showing high heterogeneity among the species. The growth exponent (b) ranged from 2.59-3.01 indicating negative allometric to isometric growth. The r value ranged from 0.7013 - 0.8240 for the three different categories showing good relationship between length and weight. The condition factor ranged from 1.39-2.83. The male recorded the highest value. The research findings indicated that the fish were in good condition. Thus, their seeds can be used for aquaculture purpose.
