Single Cell Proteins: a Novel Approach in Aquaculture Systems

摘要

The rapid growth in aquaculture and scarcity of fishmeal contribute to the high prices of aquafeeds. Currently fishmeal and soybean meal are the most common feed ingredients in aquafeeds, representing 40-60 percent of total variable costs. A serious challenge remains in reducing input costs through reducing the level of fishmeal in feeds and palliating pressure on natural fish populations.Aquaculture producers are seeking alternatives to reducing input costs to enhance profitability. Furthermore, consumers have become more health conscious. The practice of organic farming in aquaculture is one-current response to these drivers. Amongvarious alternative strategies available today, the exploitation of microorganisms in aquaculture minimizes the use of antibiotics and represents a source of high-quality protein at low cost.
