Abstract

During the present investigation, laboratory experiments were conducted to study the changes in biochemical contents such as carbohydrates, proteins, lipids, and energy levels after 96-hour exposure to Vibrio parahaemolyticus, in flower shrimp, Penaeus semisulcatus, post-larvae. The sampling was done at intervals of 24-hours, 48-hours, 72-hours, and 96-hours. The caloric concentrations as well as biochemical constituents except protein showed a decrease in infected post-larvae. In contrast, protein showed an increase in infected post-larvae. A decrease in the ratios of carbohydrate/protein and carbohydrate/lipid was observed in infected post-larvae. The differential responses of biochemical constituents might be due to triggering of compensatory mechanism under stress conditions due to V. parahaemolyticusinfection.
