Fishmeal is a high protein feed obtained from the whole fish or its offal after being processed by cooking, pressing, drying and crushing. It can be divided into white fishmeal and red fishmeal based on different wild species of raw material。

1. Varieties of Fishmeal
White fish meal is generally produced with the trimming of processed white fish raw material, including the POLLOCK, HOKI, HAKE, BLUE WHITING, COD etc. The crude protein content  can be reached above 68%-70%. In recent years, as the yields of fillets and surmmi is relative high, the protein of fishmeal declines to 60%-65% in general. Because of its high freshness and good nutrition, the nutritional value of white fishmeal is far higher than other steam dried fish meal. Besides with its high absorption and utilization, it can be used as special aquatic feed, such as eel and soft-shelled turtle. There’re 2 kinds of processing methods for white fish meal: factory vessels  processing and onshore processing. The former means to process the fish meal on vessels at the first time when wild fish were caught, therefore it has higher freshness and better quality. White fishmeal has good viscoelasticity, however, since it was produced with the offal of processed fillets, the ash in it is relative high. In some sea area such as New Zealand and Argentina, the heavy metal in the processed fish meal has exceeded the standard level.>>>TOP

Red Fishmeal: The main raw materail of red fishmeal is anchovy, jack mackerel, sardines etc and the offal of small trash fish and shrimp being processed, which is mainly used as aquatic feed and livestock feed. The crude protein of red fishmeal is normally above 65%, and some can even reach to 68%. The pure jack mackerel fishmeal is produced in south Chile, processed with nearly 100% of raw material of jack mackerel. With its biggest advantage of good viscoelasticity, high protein and conversion rate close to white fishmeal and good lysine balance, jack mackerel fishmeal is a kind of excellent raw material used for producing powder feed. >>>TOP

2. Processing Technology
Currently, China imports fishmeal mainly from Peru and Chile, where the wild caugh fish species are processed with breitlingshow advanced processing technology, thus coming out red fishmeal of high quality with stable supply. At present, most producers are adopting steam dried technology, but Peru still remains flame dried processing technic. According to the level of each index, fishmeal can be divided into different grades, including: Super Prime, Prime, Taiwan Grade, Thailand Grade, Standard Grade and FAQ (Peru flame dried fishmeal).>>>TOP
