Abstract

Short Communication on an Economic Burden of Infectious Diseases to Indian Shrimp Farming

Infectious diseases especially, Enterocytozoon Hepatopenaei (EHP), White Spot Syndrome Virus (WSSV) infections and are the major constraints in the development of shrimp farming in India. A questionnaire-based survey covering an area of 7259 ha in 23 coastal districts based on multistage stratified sampling (n=909) was conducted to estimate the Probability of Disease Occurrence (PDO) and the economic loss due to diseases was estimated. Loss of production (t ha-1 crop-1) due to WSSV and EHP was 2.58 ± 0.32 and 1.80 ± 0.24 respectively. Additionally, the total employment loss due to diseases was estimated at 1.65 M man-days worth US$ 7.07 M. The results of the study revealed 49% as the overall probability of infectious disease occurrence in the country leading to an annual loss of 0.14 M ton of harvest worth US$ 1.02 B. Prioritizing the research and implementation of specific policies would help in reducing the losses due to infectious diseases in Indian shrimp farming.
