Juvenile Penaeus monodon (body weight=10–20 g) were exposed to a commonly used organophosphate pesticide, Gusathion A, in ponds for 96 h. Prawns exposed to 1.5–150 ppb Gusathion A had 27–53% shell softening, with a 96 h LC50 of 120 ppb. Histopathological changes in the gills and hepatopancreas included slight hyperplasia of the gill epithelium, delamination of the hepatopancreatocytes, and general necrosis and degeneration of these tissues.
