The importance of water masses, natural or otherwise, in supporting fisheries, and the importance of fish as human food, cannot be overemphasized. The inland waters of Kenya act as habitats for fish, harbouring many different fish species. It has been observed with interest that certain fish species have decreased in numbers over the years within the inland waters. The decline has been at a rate which, if left unchecked, will eventually cause total disappearance of the species concerned. Thus those species have been correctly termed "endangered". Among them are Labeo, Schilbe, Alestes, Clarias and Barbus spp. |
