Formula feed for feeding sepiella maindroni

Abstract

The invention belongs to the technical field of mariculture, and particularly relates to a formula feed for feeding sepiella maindroni. The formula feed is prepared from the following raw materials in percentage by weight: 20-25 percent of wheat flour, 8-10 percent of corn DDGS, 15-18 percent of dried-powder of housefly larvae, 12-14 percent of albumen powder, 3-5 percent of beer yeast, 1-2 percent of DHA microalgae oil, 1 percent of spirulina, 2 percent of fish oil, 1 percent of licorice root powder, 5-8 percent of dried cabbage powder, 1-2 percent of black soybean meal, 0.1-0.2 percent of choline chloride, 0.2 percent of sodium chloride, 0.04-0.05 percent of L-carnitine, 2-4 percent of isomaltooligosacharide, 0.3 percent of compound bacillus, 0.05-0.06 percent of a mildew-proof agent, 1-3 percent of compound adhesive, 1-2 percent of compound mineral, 0.5-1.5 percent of vitamin complex and the balance of dregs of codonopsis pilosula. The formula feed is reasonable in ingredient formula, sufficient in raw material source and rich in nutrition of raw material ingredients, the resource utilization rate is greatly improved, and the survival rate and weight gain rate of sepiella maindroni are remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of mariculture, in particular to a compound feed for raising squid. Background technique [0002] Mansoni squid was once one of the famous "four major fisheries" in my country. In the 1950s and 1970s, the total annual catch reached about 70,000 tons. In the 1990s, the resources of Squid mansonii declined severely, and were even nearly exhausted. In 2005, more than 70,000 seedlings of Mansoni squid were fully artificially bred, of which 35,000 were artificially released, 1,130 were released in the test pond, and 536 were caught. The survival rate of breeding was 47.4%, and the maximum size was 400g. , Man's needleless cuttlefish pond culture has achieved breakthrough success. [0003] With the development of squid breeding industry in China, the compound feed that meets its nutritional needs has become one of the main factors restricting the development of squid breeding industry in my country. According to...

Problems solved by technology

In addition, the current artificial culture of Mansoni squid still mainly uses chilled small miscellaneous fish, which not only has high cost and is difficult to preserve, but also has low utilization rate and is easy to pollute water quality.
