Abstract

The invention relates to fish meal comprising at least 74% by weight of protein, up to 10% by weight of ash and up to 1.5% by weight of phosphorous. The invention further relates to use of the fish meal as a feed for fish, shrimp, cats, dogs, pigs and poultry. The invention further relates to feed for fish and shrimp comprising the fish meal. The invention further relates to a process for producing a fish meal which comprises: (i) providing a fish composition comprising raw fish meat and bones, and optionally skin and/or fins; (ii) subjecting the fish composition to mechanical separation which comprises squeezing soft components of the fish composition through perforations of a perforated drum to obtain a fraction enriched in raw fish meat, whereas a fraction enriched in fish bones, and optionally skin and/or fins remain outside of the drum; (iii) subjecting the fraction enriched in raw fish meat to cooking, then drying, and optionally grinding. The invention further relates to a process of treating a raw fish composition to increase its content of protein, reduce its content of ash and/or reduce its content of phosphorous, wherein the process comprises: (i) providing a fish composition comprising raw fish meat and bones, and optionally skin and/or fins; and (ii) subjecting the fish composition to mechanical separation to separate the fish bones, and optionally skin and/or fins from the raw fish meat which comprises squeezing soft components of the fish composition through perforations of a perforated drum to obtain a fraction enriched in raw fish meat.
