Abstract
The length-weight relationships and condition factor ‘K’ of 200 specimens of
Cynoglossus cynoglossus and Caranx hippos of Epe lagoon conducted for 6 months (May- October,2015) showed that their growth patterns were described by the formula: Log W = - 0.679+2.02 log TL and log W = -2.49+3.467 logTL respectively. A high positive correlation coefficient ’r’ of 0.97 exists between the length and weight of Cynoglossus cynoglosus that of
Caranx hippos was 0.95. The b value of 2.02 observed for C.cynoglossus showed its growth pattern was negatively allometric while that of Caranx hippos was positively allometric at 3.47 (T-test showed there was significant difference from 3.0 at P< 0.05). K factor of 0.48 was recorded for C.cynoglossus while that of Caranx hippos was 2.24.. The fact that K value
of Caranx hippos was higher than that of Cynoglossus cynoglossus shows higher suitability of Epe lagoon for the former. There is therefore a need to conduct a more indepth research on the physiochemical parameters of the lagoon in view of the nearness to industrial areas of Epe and Ikorodu coupled with the highly anthropogenic activities around the lagoon. Future
study on length-weight relationships should span not less than 12 months to cover the two hydrological cycles.
