Compound feeds are powdered or granular feeds that are formulated with a variety of feeds based on the nutritional needs of the fish. If vitamins and trace element additives are used in the formula, they are called full-price compound feeds. Formulated feeds can play a complementary role in the nutrition of various feeds, better meet the nutritional needs of fish growth and development, can promote fish growth and save feed resources. Practice has proved that squid can adapt well to compound feeds, and feeding squid with compound feed can generally achieve good results. It should promote the use of compound feed as much as possible.
1. Nutritional needs of carp: The culture of carp has a long history in China. Traditional culture mainly uses fertilization to cultivate plankton as a feed for carp. In recent years, compound feed has been used, but the nutritional needs of carp are still lacking. Enough research.
2. The formulation of squid compound feed: Because squid can obtain a certain amount of natural food in the water, its nutrition is not entirely from artificial feed, and the full price of feed is lower. In the current situation where there is insufficient research on the nutritional needs of squid, the formula for squid compound feed is more uncertain.
Practice has proved that, in the waters of the main trophozoites, the production of squid compound feeds based on the feed formulation of grass carp can get a good breeding effect. The mixed pond fish feed produced by the feed mill in the waters where the main fish is raised is also effective.
