A re-examination of tigerfish growth rates in Lake Kariba

Growth rates of male and female tigerfish Hydrocynus vittatus were determined from length/frequencies of fish from the Sanyati Basin and Sinamwenda estuary, Lake Kariba. Growth rates were similar in both sexes for the first two years, after which females grew faster and reached a greater length. Fish from the Sanyati Basin appeared to grow slightly faster than those from the Sinamwenda Estuary.
