Diversity of fish fauna in major lakes of Mandya, Karnataka.

Abstract

A study was conducted to ascertain the diversity of fish fauna in three major lakes of Mandya District in Karnataka. They were Maddur lake, Malavalli lake and Marenahalli lake. Fish community in these lakes was studied every month. Fishes were collected overnight for 12 hours using gill nets at the littoral zone at right angle to the bank. Fishes were identified. Totally 29 fish species were recorded in all the three lakes. The diversity of fish fauna in these lakes is attributed to the introduction of exotic variety, water pollution and increased anthropogenic activities.
