Single cell protein in aquaculture: A comprehensive review

Single cell protein (SCP) represents a promising remedy for the worldwide need for protein-rich foods of high quality. SCP products consist of protein meals derived from microbial or algal biomass, offering a promising solution to meet the demand for a sustainable and renewable protein source in the field of aquaculture. In this review, we identify novel SCP strains and feedstocks, discuss new feeding trial results on significant aquaculture species, including Atlantic salmon, rainbow trout, and white leg shrimp and highlight prospective sources of SCP strains and their corresponding production procedures. Sustainable production of SCP flours can be achieved by using algae or microbial biomass, utilizing waste materials from food, agriculture and cities.The use of SCP is a prominent substitute for fish protein in aquaculture diets.Protein that has been extracted from pure or mixed cultures of microorganisms, such as fungus, bacteria, yeast, or microalgae, is referred to as SCP and can be utilized in place of more traditional protein sources.The potential of SCP as a sustainable supply of protein for the aquaculture industry is thoroughly examined in this paper. It provides important information on the nutritional value of this substance and how it affects fish development and health.
