– What is fish meal?

65% – 72% PROTEIN CONTENT FISH MEAL (FEED GRADE). !!.   In the UK & Turkey the term fish meal means a product obtained by drying and grinding or otherwise treating fish or fish waste to which no other matter has been added. The term white fish meal is reserved for a product containing not more than 6 per cent oil and not more than 4 per cent salt, obtained from white fish or white fish waste such as filleting offal.  These are semilegal definitions, and for convenience fish meal can be defined as a solid product obtained by removing most of the water and some or all of the oil from fish or fish waste. Fish meal is generally sold as a powder, and is used mostly in compound foods for poultry, pigs and farmed fish; it is far too valuable to be used as a fertilizer.

-What raw material is used?

65% – 72% PROTEIN CONTENT FISH MEAL (FEED GRADE). !!.  Virtually any fish or shellfish in the sea can be used to make fish meal, although there may be a few rare unexploited species which would produce a poisonous meal. The nutritional value of proteins from vertebrate fish differs little from one species to another; whole shellfish would however give a nutritionally poorer meal because of the low protein content of the shell. Most of the world’s fish meal is made from whole fish; the pelagic species are used most for this purpose. Where a fishery catches solely for the fish meal industry, it is known as an industrial fishery.

– Preservation of the raw material

65% – 72% PROTEIN CONTENT FISH MEAL (FEED GRADE). !!.    All fisheries experience periods of glut and scarcity, leaving the fish meal factory at times with no raw material to process and at other times with too much. Large amounts of unprocessed material cause storage and odour problems; moreover spoiled material becomes difficult to process and gives a lower yield.

No cheap, completely safe method of preservation has yet been found. Refrigeration is not usually economic, and the known chemical methods of preservation have some disadvantages. Sodium nitrate with formaldehyde is very effective, but unless its addition is very carefully controlled poisonous nitrosamines can be formed when the nitrite reacts with small amounts of trimethylamine in the fish; for this reason nitrite is not used in the UK and also in Turkey. Formaldehyde alone is quite effective in keeping the fish firm enough for processing; it is most useful for species like sand eels that rapidly become semiliquid soon after catching. Although the addition of about 0-2 per cent by weight of formaldehyde is often enough to provide the required toughening effect, the preservative effect is small at this dilution, and more formaldehyde may make the fish too tough to process.

–Storage and transport of fish meal

65% – 72% PROTEIN CONTENT FISH MEAL (FEED GRADE). !!.     Fish meal is not readily spoiled by bacterial action because of its low water content, and it has a very small bulk compared to the fish from which it is made; indeed, these are two of the main reasons for making fish meal. There is no need to refrigerate the meal in storage.

Fish meal is usually stored and transported either in sacks made of paper, hessian or plastics, or in bulk. Fish meal in bulk is sometimes pelletized to make mechanical handling easier, since it does not flow readily as a powder.

Fish meal is best kept in a cool dry place protected from rodents and birds. Spoilage is normally very slight even after excessively long periods of storage; fish meal will keep for several years without detectable change in its nutritional value.

– Composition and nutritional value

65% – 72% PROTEIN CONTENT FISH MEAL (FEED GRADE). !!.    The composition of the final product depends both on the kind of raw material and on the type of process. A whole meal made from fatty fish like herring might contain about 71 per cent protein, 9 per cent fat, 8 per cent water and 12 per cent minerals, whereas a meal made mainly from white fish and white fish offal and dried to the same extent will contain about 66 per cent protein, 5 per cent fat, 8 per cent water and 21 per cent minerals

– Nutritional value

65% – 72% PROTEIN CONTENT FISH MEAL (FEED GRADE). !!.     Fish meal is valuable not only for the quantity but also the quality of its protein. By this is meant that the amino acids which make up the protein are present in just the right balance for animal or human nutrition. The amino acid composition of typical samples of herring meal and white fish meal is as follows:
