Abstract

This review aimed to place crustacean research on in vivo protein synthesis into a broader context, assess its potential for providing
further insights into crustacean nutrition and physiology, and recommend future directions relevant to crustacean aquaculture. In
crustaceans the flooding dose measurement of protein synthesis is the only method that has been used, it is relatively complex, time
consuming and uses radioactive labels. Protein synthesis provides a subtle approach to assessing imbalances and deficiencies in
dietary amino acid and energy. In addition, the calculation of protein synthesis retention efficiency (SRE) is recommended in order
to understand and optimize parameters such as feeding regime and diet composition. For prawns, SRE was highest at optimum
dietary protein content and quality. Similarly the most efficient feeding regimes in juvenile lobsters were demonstrated by the highest
efficiency of retaining synthesized protein. Understanding how various abiotic and biotic factors influence protein synthesis has
great potential for improving different aspects of crustacean aquaculture but very few studies have done this; better knowledge of
how abiotic and biotic factors affect crustacean protein synthesis will contribute to optimising growth of crustaceans in culture.
