Seasonal abundance, distribution, and catch per unit effort using gill-nets, of fishes in the Sundays estuary
Abstract
Catch per unit effort was obtained for the fish of the Sundays estuary by means of gill-netting. Fifty-five gill-net catches were made in which 1258 fish were caught in the mouth, middle and upper reaches of the estuary. Sea catfish, Tachysurus feliceps dominated catches numerically and kob Argyrosomus hololepidotus In terms of weight (31% of total). CPUE was 21 kg/standard net. Mean body weight of fish was 894 g. It seems that the food web in the Sundays estuary is based largely upon phytoplankton and dependent zooplankton grazers.
