Abstract:
Thirty-two fish species belonging to 27 families were collected from Epe Lagoon between December 2010 and July 2011. The physico-chemical parameters, air temperature ranged from 27-30.1°C; water temperature ranged from 28.7-31.5°C; pH ranged from 7.4-7.5 while salinity was 0‰, throughout the sampling period. The most occurring fish species were the elephant fish, Monodactylus sabae (100%); the sole, Cynoglossus senegalensis (87.5%), the schilbid catfish, Schilbe mystus (87.5%) and Tilapia guineensis (87.5%), respectively. From the biometric description, using fin count of each species, mouth type, no new species not occurring on the electronic database were discovered in the samples collected. The seasonal occurrence of fish species in this lagoon was not salinity influenced but probably from influences of adjacent water bodies. From length-weight relationship, b values obtained ranged from 0.28-4.37, where 40.6% exhibited negative allometric growth 36.9% showed isometric growth while 12.5% showed positive allometric growth. Condition factor (K) of species ranged from 0.20 to 5.92 with 78.12% of species having condition factors greater or equal to one, which suggested that the lagoon was suitable for most species. The lagoon is rich in fish species resource which can be properly exploited for maximum sustainable yield.

Soyinka Olufemi O.:
Thanks Sir for youur compliment. On your request, I suggest you consult Literatures on the methodology of the work; also I can suggest to you a colleague who specialises in Plankton studies and could probably have carried out research on d five cowrie creek. You may wish to contact him
Best regards |
