Length-Weight relationship and condition factor of Protopterus annectens (Owen) in Idah area of River Niger, Nigeria
A total of 62 samples of Protopterus annectens (Owen) were examined for this study from Idah area of River Niger between August and November 2008. The length-weight relationship calculated for species gave a b-value of 2.55 which is indicative of negative allometric growth. It attained a length of 59cm and weight of 397g. The condition factor varied from 0.23 to 0.76 with a mean of 0.39 + 0.08 and showed that the fish was well and in good environment for growth and survival.
