Resumo: The increase in demand for fish production drives the search for food strategies to maximize productivity. In this review, the nutritional implications of the use of exogenous proteases on fish growth were described. Exogenous proteases help in digestive processes, acting in the hydrolysis of macromolecules and in the release of smaller particles, such as amino acids and peptides. Dietary supplementation improves fish growth, mainly due to the availability and greater use of nutrients. The action of proteases is directly linked to better intake, feed efficiency and protein synthesis. On the other hand, enzyme activity depends on substrate and dietary composition as there are limitations on digestibility. Furthermore, in feed processing, thermal stability and the form of inclusion of the protease influence its efficiency. However, the increase in fish weight gain can offset the cost of including the enzyme in the diet. However, there are still gaps regarding the effects of protease in fish feeding, for example, enzyme: specific substrate and enzyme: digestive system ratio; and, stabilization technologies (mainly extruded diets), so further studies are needed.

Nesta revisão foram descritas as implicações nutricionais do uso de proteases exógenas sobre o crescimento dos peixes. As proteases exógenas auxiliam nos processos digestivos atuando na hidrólise de macromoléculas e na liberação de partículas menores, como aminoácidos e peptídeos. A suplementação dietética melhora o crescimento dos peixes, principalmente pela disponibilidade e maior aproveitamento dos nutrientes. A ação de proteases está ligada diretamente a melhor ingestão, eficiência alimentar e síntese de proteína. Por outro lado, a atividade da enzima depende do substrato e da composição dietética já que há limitações na digestibilidade. Além disso, no processamento de rações, a estabilidade térmica e a forma de inclusão da protease influenciam na sua eficiência. Contudo, o aumento no ganho em peso dos peixes pode compensar o custo de inclusão da enzima na dieta. No entanto, ainda existem lacunas quanto aos efeitos da protease na alimentação de peixes, como exemplos, relação enzima: substrato específico e enzima: sistema digestório; e, tecnologias de estabilização (principalmente, dietas extrusadas), por isso, são necessários estudos adicionais.  Departamento de Diagnóstico e Pesquisa Agropecuária.
