Microsporidian Impacts Shrimp Production: Industry Efforts Address Control, Not Eradication

摘要

Enterocytozoon hepatopenaei (EHP), a microsporidian parasite widely found in Asia and other areas, is impacting aquaculture by severely retarding the growth of cultured shrimp. EHP infects the tubules of the hepatopancreas in shrimp, which damages theorgan's ability to gain nutrition from feed. Fighting EHP entails improved biosecu-rity in the hatchery and proper pond preparation and growout management. Total elimination of microsporidians may not be possible. The best approach is to lessen the loads coming into ponds and control their levels.
