The ratio of fish meal to that of turtles is the closest. The addition of fish meal can ensure the rapid growth of various turtles. In the large-scale farming of turtles, fish meal which made the 紧凑型鱼粉机械 is the most important raw material in turtle feed, and the most important protein source in turtle feed. So far, no other raw materials can completely replace fish meal, so the quality of fish meal is of great significance in artificial turtle farming.
两种用于龟养殖的鱼粉
适合龟养殖的鱼粉饲料主要来自两种鱼粉：白鱼粉和红鱼粉。这两种鱼粉有什么区别？
1.White fish meal
白鱼粉主要由鳕鱼、鲶鱼等白鱼肉制成。制造白鱼粉的原鱼大多生活在深海中。鱼体较大，营养丰富，脂肪含量相对较低，鱼色较浅，易于保存。
The machine made white fish meal is currently the most high-grade feed raw material. It has the best effect and the highest efficiency when it is used to prepare feed for breeding animals. For example, white fish meal is indispensable in the compound feed at the seedling stage in turtle breeding.
然而，由于海洋资源的枯竭和需求的增加，白鱼粉的产量逐年下降，价格飙升。白鱼粉的主要产区在美国、俄罗斯和丹麦。近年来，新西兰的产量也显著增加。
- 红鱼粉
红鱼粉主要由沙丁鱼、鲱鱼和鲭鱼等红肉鱼制成。红鱼粉的原鱼大多生活在海洋上层，一般不适合直接食用。其资源比白鱼粉的原鱼丰富，因此年捕捞量较大。
The fish meal made by the 商业鱼粉机械 is darker in color, has a higher fat content and volatile base nitrogen value, and has lower nutritional value than white fishmeal. The main producing areas of red fish meal are in Argentina, Chile, Peru and other countries.
