Problems solved by technology

In recent years, the breeding and aquaculture of tongue sole has been rapidly developed in the coastal areas of my country. The nutritional requirements and physical properties of tongue sole for feed are quite different from those of flounder and turbot, and the existing various feeds are not suitable for them. Growth requirements of tongue sole

Abstract

The invention relates to a fish feed, in particular to compound feed for cynoglossus semilaevis gunther. The compound feed for the cynoglossus semilaevis gunther comprises the following ingredients in parts by weight: 23-25 parts of fish powder, 30-38 parts of housefly larvae powder, 5-10 parts of shell mussel powder, 10-15 parts of astragalus root dregs, 6-8 parts of yeast powder, 0.02-0.05 part of Vitamin C, and 0.01-0.02 part of Vitamin E. A plurality of ingredients are effectively mixed, proper housefly larvae powder can improve the palatability for the cynoglossus semilaevis gunther, the contents of protein and fat of the feed can satisfy the growth for the cynoglossus semilaevis gunther, the added astragalus root dregs, Vitamin C and Vitamin E can effectively reduce the infection risk of the cynoglossus semilaevis gunther, during use, a certain amount of complex feed can be added into the feed to increase microelement and basic nutrient.

Description

technical field [0001] The invention relates to a fish feed, in particular to a compound feed for tongue sole. Background technique [0002] As the main protein source of aquafeed, fishmeal has been widely used in aquaculture because of its high protein content, balanced amino acid composition, good palatability, and low anti-nutritional factors. The scale of aquaculture in the world is growing at an annual rate of 11%, but the annual output of global fishmeal is declining. In recent years, the annual output of fishmeal has only been maintained at 6-7 million tons, resulting in an imbalance between the supply and demand of high-quality feed protein sources. Therefore, finding high-quality fishmeal substitute raw materials and studying the addition ratio of alternative protein sources have become key issues for the sustainable development of aquaculture. Soybean meal has been widely studied as a high-quality fishmeal substitute because of its high protein content, reasonable...
