Changes of lipid components in midgut gland and muscle of penaeid prawns, Metapenaeus monoceros and Penaeus indicus exposed to phosphamidon

Abstract

Changes in lipid levels in midgut gland and muscle tissues of prawns, Metapenaeus monoceros and Penaeus indicus were studied following exposure to sublethal levels of phosphamidon. Total lipids and glycerol significantly decreased while lipase activity in phosphamidon exposed tissues increased. Increase in fatty acids and total cholesterol suggest elevated cellular lipolysis indicating lipid breakdown and utilization to meet higher energy demands. Variations were tissue specific and more pronounced in midgut gland especially in P. indicus
