Abstract:

The length - weight relationship and condition factor of Callinectes amicola from Okpoka Creek in the Niger Delta area of Nigeria was studied for a period of one year. The exponent b values for all the sexes ranged from 2.336 and 2.56 (males), 2.367 and 2.536 (females) and 2.352 and 2.548 (combined sexes) respectively. Growth generally exhibited a negative allometry in all the sexes as shown by the mean exponents (b=2.448) for male, female (b=2.451), combined sex (b=2.449). Generally, the regression equations revealed high correlation in all the sexes as the correlation coefficient (r) values for male (0.951), female (0.971) and combined sexes (0.961) are very close to r = 1. The monthly K values of the males ranged from 0.0984 and 0.1503 (mean = 0.1214). The estimated K value for both sexes combined was 0.1260. Similarly, estimated K values for the females ranged from 0.0889 0.1524.The overall mean K value for the females was 0.1229. The minimum K value (0.0984) for the male was observed in February. The female C. amnicola minimum K value (0.0889) and Kmax (0.1580) values were obtained in November.
