Partial Substitution of Fish meal with a Mix of Animal and Vegetable Feedstuffs for Rainbow Trout in Argentina

摘要

Fhmeal continues to be one of the main protein sources used in commercial feeds for trout and salmon, although its availability is not expanding and its cost is increasing (Figueiredo-Silva and Lemme 2014). Toward sustainable aquaculture, Naylor etal.(2000) proposes a reduction of fishmeal and fish oil input in feed and promotion of environmentally sound aquaculture practices. Many investigators have replaced partially or totally replaced fishmeal with several animal or plant protein sources for different fish species. Previous experiences carried out at CENADAC with pacii and South American catfish (both omnivorous species) demonstrated that it is possible to totally substitute fishmeal with animal and plant feedstuffs (Wicki and Luchini 2004, Wicki et al. 2008).
