Abstract


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.
