Tilapia (Oreochromis niloticus) is one of the most cultivated freshwater fish. The problem that is often faced in fish farming is diseases caused by parasitic attacks (ectoparasites) which can cause a decrease in fish production levels. To overcome these problems, research is needed on the intensity and prevalence of ectoparasites in tilapia (Oreochromis niloticus) to determine the density of ectoparasite attacks and the percentage of ectoparasites in tilapia. Tilapia (Oreochromis niloticus) samples were taken from the Floating Net Cage (KJA) of Lake Batur, Songan Village, Kedisan and Trunyan.

Abstract:

This study was designed to determine the size variations of the family of Cichlids in lower river Benue. The fish samples were collected bimonthly in batches for a period of three months (September- November, 2023). A total of 120 fishes comprising 60 each of Tilapia zilli and Oreochromis niloticus were sampled from fishermen at the Wadata landing site during this period. The fish sampled were transported in an ice-parked plastic container to the Fisheries laboratory in order to keep the integrity of the sample intact prior to analysis. The species were identified using taxonomic keys and morp
