Problems of diseases in prawn projects.

Abstract

A major factor that influeces the success of production in the prawn industry is the occurrence of disease. Early stage of prawn in hatchery-nursery systems are subject to attacks of viruses, bacteria, fungi and protozoan pathogens. Although these microbial disease agents may also invade prawn juveniles and adults, nutrition and environmental diseases appear to play more important roles in grow-out ponds. Control of diseases involves correct diagnosis, prevetion and treatment. Rigid sanitay practices in hatchery followed by effective management through dietary and environmental manipulation in grow-out ponds are highly recommended
