Appraisal of the current fish composition, abundance and operative fishing gears in Tomas Dam Danbatta, Kano State and Daberam Dam Daura,Katsina State
The current study explores information on fish diversity and fishing gears used in Tomas Dam Danbatta, Kano State and Daberam Dam Daura, Katsina State. From the results 5 different species belonging to 3 families were found in Tomas dam, and these are; Tilapia zilli, Oreochromis niloticus and Sarotherodon galilaeus belonging to the Family Cichlidae, Clarias gariepinus from the Family Claridae and Lates niloticus from the Family Centropomidae. Whereas in Daberam Dam, 6 species belonging to 5 families were observed and these are: Oreochromis niloticus, Hemichromis bimaculatus (Family Cichlidae), Clarias gariepinus (Family Claridae) and Eutropius niloticus, Hyperopiss bebe and Alestes beramoze from the Family Shilbeidae, Mormyridae and Alestidae respectively. The research also revealed that, Cichlidae were the most dominant fish type in these two Dams with Oreochromis niloticus leading specie in Tomas dam, with 61% percentage abundance, while Hemichromis bimaculatus is the most abundant species in Daberam Dam having 85% percentage abundance. The types of fishing gears used in both Tomas and Daberam Dam are similar with triggered trap dominating the fishing site in each dam.
