recorded in the Ologe Lagoon, South-West Nigeria. Adult stages of 12 of
them were freshwater (48%), 4 were estuarine (16%) and 9 were near-shore
marine species (36%). The slight seasonal variation in the catch composition
of the fish fauna of the lagoon was attributed to the slight seasonal
fluctuation in salinity marked with higher rainfall volumes in the rainy
season than in the dry. Availability of food organisms was also noted
for the seasonal distribution of some of the fish species. Temperature
and pH varied slightly, while DO was higher in the dry season but lower
in the rainy season. Distance from salt water influence and much river
influx with the associated reduced salinity appear to be the major meteorological
forcing operating in the lagoon. The lagoon is very low brackish water.
The highest species richness was observed in September with 13 species,
while the lowest with least abundance was observed in August (when there
was a break in rains) with 7 species. The most abundant species during
their occurrence were T. mariae (10.1%), C. senegalensis (9.84%)
and M. electricus (7.51%). Species richness and total abundance
were found to increase slightly during the rainy season than the dry season.
Availability of much juvenile forms indicated that the lagoon forms a
good nursery ground for many fish species.]]>Albaret, J. and R. Lae,20031619Bates, D.E., K.A. Fanning and J.J.
