Length-weight, Length-length Relationship and Condition Factor of Synodontis robbianus at Idah Area of River Niger, Kogi State, Nigeria
Abstract
The length-weight, length-length relationship and condition factor of Synodontis robbianus in the lower Niger River (Idah), Nigeria was carried out. One hundred and fourteen (114) fish samples of total length ranging from 8.8-16.0 cm and weight between 4.3 g and 43.4 g collected between January and August, 2008 were analyzed. Results showed allometric growth for the sampled fish with regression coefficient (b-value) of 2.9926, 2.7620 and 2.8355 for males, females and combined sex respectively. The regression coefficient (b-value) for the length-length relationship was 0.9418, 0.9602 and 0.9510 for males, females and combined sex while the condition factor of all the sampled population varied from 1.57-3.83. The Idah area of River Niger in Kogi State is a good environment for growth, reproduction and survival of the fish species.
