A review on the status of protein nutrition of Argentine penaeoid shrimp: Comparison and contrasts within the Penaeidae

Abstract

Protein is the major and the most expensive ingredient in shrimp feeds, as well as a growth limiting nutrient. This paper 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 these species is the inadequate knowledge of their nutritional requirements. The present review focuses on applied nutrition of protein, protein sources in feed, and apparent digestibility. Also considered are 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 for other penaeoid species. This review provides a better understanding of feeding preferences and the formulation of suitable feeds for shrimp, which is essential to optimize the use of ingredients and reduce feed costs.Pleoticus muelleri Bate, 1888 and Artemesia longinaris Bate, 1888.
