Problems solved by technology

In order to develop the pike perch farming industry, in recent years, some areas have also tried to domesticate pike perch with artificial compound feed. It is found that after domestication, pike perch can eat artificial compound feed. The lack of bait provides a new way, but at present, due to the lack of a complete set of mature zander domestication methods, its domestication rate is low, generally only reaching about 30%, so the successful establishment of zander domestication technology has become a technical problem for this fish breeding

Embodiment 1

[0046] A method for domesticating pike perch seed by using artificial compound feed, comprising the following steps:

[0047] 1) Stock the pike perch fry in the domestication pond, and stop feeding within 2 days after being put into the domestication pond. The domestication pond is a cement pond, a PE material pond or a glass tank pond, and the water temperature in the domestication pond is 19-23°C , the dissolved oxygen content is greater than or equal to 6.5mg / l, the diameter of the domestication pond is 2.2m, the average water depth is 0.6m, the water body exchange time is 2 hours / time, the average body length of zander fry is 3-6cm, and the fish put into the domestication pond The density is 800-1000 tails / m 3 , domesticated volume is about 2.28m 3 , the delivery volume is about 1824-2280 tails;

[0048] 2) From the third day, live bait was fed at fixed times at 8:00 am, 11:00 am, 14:00 pm and 17:00 pm respectively, and at the same time, the pond wall was tapped to give ...

Abstract

The invention discloses a method for domesticating zander fry by using artificial compound feeds. The method is implemented by adopting live baits, minced fillets, soft particle feeds and hard particle feeds. The method for domesticating the zander fry by using the artificial compound feeds provided by the invention has the beneficial effects of solving the problems of single bait source, instable bait quality and inconvenience in feeding caused by the throwing of fresh and alive or chilled and fresh wild fish, eliminating a difficult problem in establishing a zander artificial domestication technique, improving the domestication success rate to 73.4%, and building up a whole set of complete and mature method for domesticating the zander fry by using the artificial compound feeds.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for domesticating zander seedlings by using artificial compound feed. Background technique [0002] Zander (Luciopercalucioperca) belongs to the order Perciformes, family Percidae, and the genus Stizostedion. Also known as Jiudaohei, it was originally distributed in the rivers and lakes of the Aral Sea, Black Sea, Caspian Sea and Baltic Sea in Europe. In the early 1960s, it spread from Central Asia to the Ili River and Irtysh River systems in Xinjiang, my country. Sexually ferocious fish. [0003] Zander has fast growth, tender meat, few intermuscular spines, high nutritional value, and its protein content exceeds 20.53%. It is a rare cold-water fish in my country and the main consumer fish in many European countries. It has huge market prospects and export potential. At present, domestic pike perch farming mainly feeds fresh or chilled wild fish. After years of farming, vari...
