| Sumario: | Changes in production technology and marketing and changes in feed ingredients are key structural transformations necessary for the aquaculture sector to grow. Today, with improved genetic techniques novel genetic lines are being bred for maximum efficiency over a shorter production period with lower feed conversions. Thus, the correct amount of micro-nutrients present in their diet is crucial. Fishmeal has always been the main source and the preferred choice of nutritionists for quality protein, above all in the formulation and especially in feeds for the youngest ages. Though, with the market volatility of fishmeal, the aquaculture feed industry is looking for cheaper sources of protein to substitute the fishmeal and this has become a priority. Additional renewable and sustainable protein alternatives are needed. Animal byproducts are well accepted as aqua feed ingredients these days due to short supplies and escalating cost of fishmeal. Protein content in animal byproducts is higher and their complement of indispensable amino acids is superior to those of plant origin. In addition, animal Co-Product Hydrolysates (ACPH) can meet the many nutritional needs of aquaculture worldwide as a protein alternative in aqua feeds. ACPH's can help reduce pressure on natural fisheries stocks and provide sustainability to the growing demand for aquatic products.
