Changes in Biochemical Constituents and Energy Levels of Flower Shrimp,Penaeus semisulcatus,Infected with Vibrio parahaemolyticus

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.
