Importantes aspectos da nutrição do Zebrafish (Danio rerio) em biotérios

Abstract

Research carried out with animals has increasingly required the possibility of reproducing the experiments and comparing the results obtained, one of the factors of great importance and influence on the quality of research animals is nutrition. The nutrition of laboratory animals is very relevant when we consider that animals need a diet that meets all their requirements, taking into account that they are in a controlled environment and contained in limited spaces with access only to the diet offered. When in the wild, animals select what to feed on, thus having a varied diet that meets their nutritional needs. An even greater challenge arises when we approach the nutrition of Zebrafish (Danio rerio), as they have a wide possibility of food sources and, being an omnivorous fish, the food sources of this species are very vast and still have few commercial options for food defined formula feeds for research animals. In addition, there is also concern about the interference of this diet correlated with diseases and even the quality of the water where the animals live. This review aims to outline a current overview of Zebrafish nutrition and the need to define rations with a standardized formula in order to improve research results.
