| Popis | Complete sample examined for presence of metazoan and selected protist parasites consisted of more than 700 fish individuals from 41 species. Main results: A total of 47 fish species of 19 families were observed at three sites in Turkana Lake. The most common parasites found on 41 investigated fish species were Crustaceans parasitizing on the gills and body surface of 31 fish spp. Likewise, heavy loads of Monogeneans were recorded on the body surface, fins, and gills and rarely in the stomach of 27 fish spp. Other groups of parasites were represented by both larval (Contracaecum sp. in 6 fish spp.) and adult stages of Nematodes in 25 fish spp., larval and numerous adult Cestodes in 19 fish spp., Digeneans in 18 fish spp., Myxosporidians in 7 fish spp., Acanthocephalans in 6 fish spp., Hirudineans in 3 fish spp. and Pentastomids in 2 fish spp. Conclusion: Two of fourty seven fish species determined were considered as new records for Turkana-Omo basin. Significant proportion of parasite species, especially Monogeneans, were found as new for science. |
