Digestive Enzymes in E.suratensis (Pearlspot) & O.mossambicus(Tilapia)

The book deals with the study of digestive enzymes in Etroplus suratensis (Pearlspot) and Oreochromis mossambicus (Tilapia). Both of these fishes can survive in brackish as well as fresh water ecosystems. Once introduced in to a habitat, tilapia can be a threat to native species. Such adaptive ability could be the reflection of their capacity to explore different feeds available in the habitat. Thus, the information on digestive enzymes can provide basic knowledge to understand the nutritional status and helps in comparison of digestive capabilities of fishes. Tilapia has a remarkable specific activity throughout their digestive tract than that of Pearlspot. It is noted that Tilapia has a higher values for various physiological indices in comparison with Pearlspot and indicates its dominant adaptive physiology. The study suggest that live probiotic microorganisms like Micrococcus and Bacillus may be incorporated while formulating the cost-effective, nutritionally balanced diet for better growth performance and nutrient utilization of these fishes. Fish digestive enzymes can be used as biochemical tools to study and develop various industrial and therapeutical applications.
