Short communication: Effects of different protein sources on growth performance and food consumption of goldfish, Carassius auratus

Protein is one of the most important components in a fish diet. In aquaculture, the primary dietary animal protein source is fish meal, but its availability is limited and supply varies because of reductions in fish stocks related to factors such as climatic phenomena, and overexploitation and decline of ocean fisheries stocks. This variability can seriously affect aquaculture sustainability and provability, and therefore research in identifying alternative dietary protein sources has increased. Fish nutritionists have tried to use less expensive plant protein sources to partially or totally replace fish meal. ... The purpose of this study was to investigate food consumption and growth performance of goldfish fed diets containing only plant, only animal and plant-animal (50%-50%) derived protein source
