Fontes proteicas na criação de peixes: alimentos alternativos

Abstract

Food represents the highest cost in the production of fish farming, where rations represent about 60% to 70% of this cost, which its preparation contains more ingredients of both animal and vegetable origin, being an expensive protein item in the production of rations. Alternative foods are an option for replacing the most expensive raw material with others with greater availability and lower economic cost. The objective of the work was to analyze possible alternatives for the replacement of fish meal, an ingredient of animal origin, in diets in fish farming. Plant-based foods can be used as alternative sources for better utilization of alternative food sources for alternative food of fish flour and flour. The work carried out through the exploratory fish research path, developed from elaborated material, was used scientific articles, dissertations, books and theses. The material used was accessed in the databases Scielo, Science Direct, Google Scholar, Capes, Instituto de Pesca, Aquaculture Brasil and Revista Ciência Agroómica, published in the last 22 years (2000 to 2022) in Portuguese and English. A study was carried out with the purpose of summarization according to information contained in the sources studied. In this way, the work emphasized the use of alternative foods as a function of supplying the protein content necessary for feeding fish products, relating potencies with their specifications and potential. Thus, it is up to the fish farmer to analyze the best option to be used.
