New developments in aquatic feed ingredients, and potential of enzyme supplements por W. Hardy, Ronald

“…Suitable alternative feed ingredients will have to beenutilized to provide the essential nutrients and energy needed to fuel the growth of aquaculture production.Rendered products, seafood processing waste, including by-catch, and grain and oilseed by-products are themost likely candidate feed sources to carry aquaculture forward to higher production levels. Worldwide,annual production of rendered products is roughly equivalent to annual fish meal production, with meat andbone meal and poultry by-product meal making up 80% of total production. …”
