A REVIEW ON THE STATUS OF PROTEIN IN FEEDS OF ARGENTINE PENAEOID SHRIMPS.   Protein is the major and the most expensive ingredient in shrimp feeds and a growth limiting nutrient. This work reviews the results of investigations designed to understand the protein nutrition in the most abundant penaeoid species in the Argentine Sea, Pleoticus muelleri (Bate, 1888) and Artemesia longinaris Bate, 1888. One of the main obstacles to culture of these species is the inadequate knowledge of their nutritional requirements. The present review focuses on applied nutrition of protein, protein sources in feed; apparent and in vitro digestibility. It was also considered digestive proteinase activity in relation to developmental stages and molting cycle, amino acid requirements, and optimal protein levels measured by growth responses. These results are compared with those obtained with other penaeoid species. The present review will allow a better understanding of feeding preferences and the formulation of suitable feeds for shrimp, which is essential to optimize the use of nutrients and reduce costs.
