Length-weight relationship and condition factor of Leuciscus niloticus (De Joahhis, 1853) from Epe Lagoon, Lagos State, Nigeria

Leuciscus niloticus samples were obtained from Epe lagoon, Lagos state, Nigeria. The fish samples were designated into pooled, male and female sex respectively. Length-weight relationship was carried out to investigate the correlation value, growth pattern and the condition factor (k) of pooled, male and female Leuciscus niloticus. In this study, the growth pattern of pooled, male and female Leuciscus niloticus from Epe lagoon shows that the "b" values were 2.56, 2.62 and 2.38 respectively, showing that all the fish sampled exhibited negative allometric growth pattern. The overall length weight regression equation for pooled was (Log W = -1.679 + 2.559 log TL), (r = 0.898), and also the length-weight equations of males and females (Log W = -1.759 + 2.618 log TL) (r=0.919), (Log W = -1.449 + 2.384 log TL) (r=0.870) respectively. The mean condition factor (k) of Leuciscus niloticus was 0.55 ± 0.08 for pooled, 0.54 ± 0.08 and 0.55 ± 0.09 for both male and female respectively indicate poor adaptation of the fish in the Epe lagoon.
