Two small earth ponds (surface area 170 m2, depth 80 cm) on Lake Trasimeno (central Italy) were stocked at two different densities (2.8 and 7/m2) with juveniles of Macrobrachium rosenbergii weighing an average of 10.5 g. Water exchange was 60 1/sec/ha, and water temperature ranged from 17 to 28°C. The prawns received 5% of their live weight in pellets for catfish, twice daily for 120 days (June to October 1987). At the lower stocking density, survival rates of 91.2% and average final weights of 65.9 g were obtained; at the higher density, these rates were 87.3% and 49.1 g respectively.

Abstract

Two small earth ponds (surface area 170 m2, depth 80 cm) on Lake Trasimeno (central Italy) were stocked at two different densities (2.8 and 7/m2) with juveniles of Macrobrachium rosenbergii weighing an average of 10.5 g. Water exchange was 60 1/sec/ha, and water temperature ranged from 17 to 28°C. The prawns received 5% of their live weight in pellets for catfish, twice daily for 120 days (June to October 1987). At the lower stocking density, survival rates of 91.2% and average final weights of 65.9 g were obtained; at the higher density, these rates were 87.3% and 49.1 g respectively.
