Abstract

Assessment of length-weight relationship and condition factor of a commercially important mollusc species, Periwinkle, Tympanotonus fuscatus, from Okrika estuary was conducted from October, 2015 to February, 2016. A total of 120 samples of the species were hand-picked from the mangrove ecosystem of Okrika. The results obtained showed that the gastropod species had negative allometric growth patterns with a growth exponent, b value of 2.18. This value was confirmed as negative allometric, because it was significantly different (p<0.05) from 3 when a t-test was carried out. The mean condition factor, K of the species was18.9, which indicated that they were in good condition during the sampling period. This study recommends that further research needs to be conducted because it is the first of its kind in this estuary and that the sampling duration was one-third of a year (4 months). Also efforts should be taken to reduce the pollution load in order to safe-guard this valuable resource for the local population.
