Food Restriction Programs and Their Applications in Fish Aquaculture

Abstract

Food restriction is a strategy to improve the productive efficiency of some aquatic organisms. It is expected with the implementation of food restriction programs to first reduce the feed consumption by the cultivated species and consequently reduce the waste load in the water. In addition, there is a lower employment of labor during periods of food restriction. However, the efficiency of the feed restriction and the compensatory gain of weight by the organisms cultivated will depend on the adaptation and the characteristics of the species in question. Several methodologies have tested forms of food restriction applied to fish farming. Some of them are addressed in this review, as well as results and comparisons made with several authors on the subject in question. The purpose of this paper was to describe the main reasons for using food restriction, its implications on fish organism and to compare results from previous studies
