Artificial compound feed for perca fluviatilis and feeding method

Abstract

The invention discloses an artificial compound feed for perca fluviatilis. The artificial compound feed comprises the following components in percentage by weight: 8.0 to 51.5 percent of fish meal, 1.00 percent of fish oil, 1.00 percent of corn oil, 0.24 percent of choline chloride, 1.1 percent of vitamin premix, 1.9 percent of inorganic salt premix, 0.55 percent of calcium dihydrogen phosphate, 0.18 percent of lysine, 0.45 percent of methionine, 8.2 to 15.46 percent of bran, 21.2 to 26.6 percent of wheat middling, 6.01 to 12.82 percent of rapeseed dregs, 0.88 to 2.65 percent of globin powder, 14.87 to 16.79 percent of bean pulp, 10.23 to 12.47 percent of cottonseed pulp and 2.5 to 5.8 percent of yeast; and the components are puffed into a floating granular feed by a conventional method. The invention also discloses a perca fluviatilis feeding method. According to a culture mode of mainly feeding the perca fluviatilis and matching carp, bighead carp, silver carp, tincaeus, grass carp and pelteobagrus fulvidraco Richardson, the perca fluviatilis can be completely domesticated to take the compound feed in 7 to 15 days by adopting the compound feed and a unique intake domesticating method; the feed problem is solved, the water layer and the bait resource of a culture water area are fully utilized, and the growth speed and the yield of the perca fluviatilis are improved; and the compound feed can be used for large-scale culture of the perca fluviatilis.

Description

technical field [0001] The invention belongs to the field of aquaculture, and specifically relates to an artificial compound feed and a feeding method for Eurasian perch. Background technique [0002] Eurasian perch (Perca fluviatilis) belongs to Perciformes, perch family, perch genus, also known as perch, five black, colorful grouper and red perch. It is widely distributed in the cold temperate zone of Europe and northern Asia. In my country, it is only produced in the waters of the Irtysh River, Ulungu River and Bosten Lake in Xinjiang. Thorn, rich in essential amino acids, rich in protein, low in fat, is a treasure among freshwater fish. There is a saying that "you can't think of fish after tasting perch", and is favored by consumers; it has wide salinity and Wide temperature, fast growth, especially suitable for breeding in reservoirs with low water temperature all year round, and strong disease resistance. Because Eurasian bass is gluttonous and easy to catch, it is also...

Problems solved by technology

[0003] According to the nutritional value, good adaptability, disease resistance and market price of Eurasian perch, it can be promoted in pond culture and reservoir cage culture. Copepods, copepods and other plankton are the main bait, and sometimes aquatic insects and small crustaceans are also eaten. Adult fish feed on small fish and shrimps. However, in large-scale breeding, natural fresh bait fish and chilled fish are difficult to supply adequately. , they kill each other when there is a shortage of feed. The fish species purchased on the market are all fish species that have been fed with bait fish. They have a certain resistance to ingesting artificial compound feed, which adds a certain degree of difficulty to domestication, so artificial compound feed is ingested. and domestication of Eurasian seabass is the bottleneck of its culture
