Small Indigenous Fish  Species (SIFS) meal is made from small, pelagic Indigenous fish . Fish meals contain crude protein levels above 66%, fat content around 8 to 11%, and ash generally below 12%. It is sometimes produced after sun-drying and grinding, and can have very high levels of ash and relatively low protein levels. Fish meal is also a valuable source of minerals calcium, phosphorous, magnesium, potassium, of vitamins B1, B2, B6 and B12, and of trace elements, notably zinc, iodine, iron, copper, manganese, cobalt, selenium and fluorine. Fishmeal normally contains between 60% and 72% crude protein by weight. From a nutritional standpoint, fishmeal is the preferred animal protein supplement in the diets of farm animals and often the major source of protein in diets for fish and shrimp.
