Abstract

Found in the major South American river basins, the surubim (Pseudoplatystoma sp) is Pimelodidae family fish and have great economic importance. It possesses nocturnal characteristics and carnivorous alimentary habits. It is one of the freshwater fish with bigger commercial value. Surubim has a great production potential and its meat is of excellent quality. The reduction of the natural reserves is stimulating its farming, but there is still not available a complete technological package for that yet. The main limitations for the surubim farming are the reproduction and the nutrition mainly of the young phase fish. Aspects of importance, production, reproduction, nutrition and strategies of evaluation of foods and determination of nutrition requirements of surubim are approached in this article.
