How to prepare carp feed?

Scholars at home and abroad have done a lot of research on the nutritional requirements of carp feed. The results show that the protein requirement of carp is lower than that of carnivorous fish such as rainbow trout and higher than that of plant fish such as grass carp, and its suitable amount is 38.5% (Ogino). Starch can also be well utilized. The requirements and utilization rate of protein in feed of carp are also different in different growth stages, different water temperature and water quality, as well as different culture methods. The crude protein content of Japanese carp feed is generally more than 39%. At present, the protein content level of carp formula feed in China is also different due to different regions and culture methods. In general, the crude protein content of formula feed in adult fish culture stage is 28%-35%, and that in fish culture stage is 35%-40%. When the pond is not closely reared or the temperature is low, the crude protein content of the feed is lower. On the contrary, the feed contains less crude protein. According to the data obtained by some scholars on the nutritional requirements of carp word feed, and combined with the existing feed resources and feed cost in China, the standard of compound feed for carp at different growth stages has also been established. The nutritional composition index is shown in Table 49.

Summary: the above content is for you to sort out the introduction of what carp to eat, hoping to help the needy partners.
