Formulated hatch feed of young penaeus

Abstract

The invention discloses formulated hatch feed of young penaeus, which consists of the following components by weight percent: 30 percent to 65 percent of excellent white fish meal, 7 percent to 5 percent of fish oil, 10 percent to 20 percent of steam fish meal, 3 percent to 10 percent of cuttlefish visceral meal, 2 percent to 10 percent of soybean meal, 0.5 percent to 3 percent of vitamin mixture, 2 percent to 10 percent of peanut meal, 0.5 percent to 3 percent of mineral substance mixture, 10 percent to 30 percent of flour, 0.2 percent to 2 percent of astaxanthin, 0.2 percent to 2 percent of phospholipid and 0.1 percent to 2 percent of ecdysone. Aiming at the growing and physiological digestion characteristics of the young penaeus larvae during hatching period, the formulated hatch feed selects feed materials with high utilization rate, is prepared through ultramicro-pulverization technology, promotes rapid growth of the young penaeus effectively, improves survival rate of transformation of the young penaeus, and strengthens the resistance ability of the young penaeus. The formulated hatch feed has reliable material source, stable quality and low price.

Description

technical field [0001] The invention relates to a prawn seedling feed combined with an open mouth. Background technique [0002] Prawns (litopenaeus.sp) are mainly cultivated in China, including Litopenaeus mondon and Litopenaeus vannamei, especially the latter. The annual output in my country has reached nearly 1 million tons, and gradually formed from A huge industrial chain of broodstock introduction, seed cultivation, ecological breeding, processing and export, the development of the industry is inseparable from the improvement of its technical level. In view of the fact that prawns have become the most important species of prawn farming in my country, and the scale of their farming is gradually expanding, the problem of prawn seedlings has increasingly become a key issue for the development of the industry. High-quality shrimp seedlings with neat specifications, fast growth speed and no germs are the necessary guarantee for the development of the industry. The growth o...

Problems solved by technology

[0003] In China, the current bait for cultivating prawn seedlings is mainly Artemia and other feeds prepared by existing technologies. Artemia is generally produced in Salt Lake City, the United States and Qinghai, China. The price is expensive, and the key is that it seriously damages resources and the environment. Moreover, the supply of Artemia worms is getting less and less, which greatly increases the cost of seed cultivation; other feeds prepared by existing technology cannot accurately select the growth and physiological digestion characteristics of shrimp larvae at the opening stage , and the manufacturing process is relatively rough, therefore, the utilization rate of these feeds is not high, and the remaining materials are left in the aquaculture water body, resulting in serious pollution and eutrophication of the water body, all of which seriously threaten the sustainable development of the shrimp aquaculture industry
