The aim of the project is to produce hydrolysed proteins or fish protein hydrolysates (FPH) from side streams from mackerel processing, and evaluate the feasibility of using them in starter feed for salmon farming, as well as for human consumption.

A lot of emphasis has been placed on value creation in the fishing industry in recent years and much has been done regarding the utilization of side currents from pollock fish, but less is applicable to the same currents from pelagic species. Mackerel is one of the most important pelagic species off Iceland, and more than 100,000 tonnes are processed in the country every year, with the corresponding amount of by-products, such as heads, guts and trimmings. These side streams have so far only been used for the production of fishmeal and fish oil, and there is therefore great potential for increasing their value.
