The knowledge of length-weight relationship parameters has numerous practical applications in fishery research and management. However, there is currently dearth of information on the growth pattern and state of well-being of Parachanna obscura in Eleyele Reservoir. This study therefore investigates the allometry and condition factor of P. obscura inhabiting the Eleyele Reservoir, Southwestern Nigeria. 688 specimens of P. obscura were collected from artisanal fishers’ at their landing sites on a bimonthly basis for 24 months. Standard Length (SL, cm), and Body Weight (BW, g) were measured. Length-Weight Relationships (b>3 or <3-allometric; b=3-isometric), and condition factor (K) were calculated using standard formula. Data were analysed using descriptive statistics and ANOVA at α0.05. The SL and BW of P. obscura ranged from 10.6 to 39.2 an.. Read More»
