Abstract

An analysis was made on the stocking density, survival, growth and production of Penaeus monodon in semi intensive (SI) and modified extensive (ME) shrimp culture ponds located in East Godavari district of Coastal Andhra Pradesh, India. Survival of shrimp in the ME systems with low stocking densities is higher (56 - 88%) than in the SI systems (12.3 – 52%) with higher stocking densities. Growth of shrimp is dependent not only on the stocking density but also on the management practices. Although the percent survival is more in ME system the growth is much faster in SI system owing to better management practices. Weight gain of shrimp was more rapid in the SI system than in the ME system initially up to 90 days of culture (DOC) but the trend was reverse in the later age of culture period. The optimum stocking density for achieving maximum production in the area is suggested as 10-15 individuals / m2 in SI ponds and 3-5 individuals / m2 in ME ponds.
