In Turkey, it is known that, wastes of fisheries processing plants released to the environment and only a bit of that assessed as fish meal or fish feed by a few plant. It is expected that with the evaluation of these wastes which rich in nutrient content by converted to the various commercial products (chitin, protein hydrolyzate, carotenoprotein and pıgment extraction etc.) to be beneficial i...

Beyond the technical and technological advances in the conversion of marine by-products into useful products, the economic, social, political and environmental parameters, are to be taken into account to understand why and how bioconversion technologies of fish by-products are applicable. The fish sector is facing several issues such as wild fish stocks reduction while in the same time the cult...
