Problems solved by technology

In most cases, powdered feed is pressed into soft granules for feeding. The processing is cumbersome, the amount of feeding is not easy to grasp, and it is easy to cause feed waste and pollute the breeding water. The comprehensive utilization of residual bait and feces in the water body There is no better solution

Embodiment 1

[0024] The present invention provides a kind of mandarin fish culture method that throws something and feeds puffed compound feed, comprises the following steps:

[0025] (1) Select a pond with an area of ​​5 mu, a water depth of 2.6 meters, convenient water inlet and drainage, and good water quality. Before the pond is flooded, 100 kg of quicklime per mu is used to sprinkle the whole pond. After 7 days, the water is filled to a depth of about 1m, and EM bacteria are applied per mu. Liquid 2.5L / mu, yeast paste 2kg / mu, then gradually add water to 2.5m;

[0026] (2) Set up 10 net cages (total area 360m2) in the center of the pond with a length × width × height of 6m × 6m × 2m (into the water depth of 1.5m). 2 ), the mesh size of the net cage is 2cm, and it is suspended for 7 days before the mandarin fish species are stocked, and the fish can only be released after the net cage is smooth, so as not to cause scratches, and the net cage is connected with the pond stalk with a float...

Embodiment 2

[0033] The present invention provides a kind of mandarin fish culture method that throws something and feeds puffed compound feed, substantially with embodiment 1, difference is: described pond area is 10 mus, and described net cage is 20 (total area 720m2) 2 ), the mesh size of the net cage is 4cm; the mandarin fish puffed compound feed is made up of the raw materials of the following mass parts: 45 parts of Peruvian fish meal, 13 parts of soybean meal, 7 parts of peanut bran, 5 parts of meat and bone meal, and 3 parts of hemoglobulin powder 15 parts of high-gluten flour, 2 parts of squid paste, 2 parts of yeast paste, 1 part of calcium dihydrogen phosphate, 2 parts of fish oil, 2 parts of soybean oil, 2 parts of soybean lecithin, 0.1 part of vitamin premix, 0.3 parts of choline chloride 0.1 part of glycine, 0.2 part of taurine, and 0.3 part of yeast nucleotide.

Abstract

The invention provides a mandarin finish breeding method with a puffed compound feed. The mandarin fish breeding method with puffed compound feed comprises the following steps: selecting a pond with an area of 5-15 mu, a water depth of above 2.5m, convenient water intake and water drainage, and good water quality; erecting net cages in the center of the pond, and the net cages are connected with the pond banks through floating bridges; two nano -microporous oxygenation aerators and one feeding area are arranged in each net cage, and 2-4 sets of waterwheel type oxygenation machines are arrangedat the outside of the net cages; adding mandarin fish fry in domestication net cages for domestication until the mandarin fish fry is domesticated to eat the puffed compound feed; 40-60 g of the mandarin fish fry which is adapted to eat feed is sorted into breeding net cages, and are fed with the mandarin fish puffed compound feed; and the outsides of the net cages are matched with aristichthys nobilis fry, silver carp fry, fingerling fry and giant freshwater prawns. The mandarin finish breeding method with the puffed compound feed through erecting net cages in the center of the pond has theadvantages of fast growth rate, neat specification of finished product breeding, low fixed input, easy conditioning of water quality, conveniently catching, and conveniently feeding and the like, cansignificantly improve ecological, economic, and social benefits for the mandarin finish farming industry.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a mandarin fish culture method of feeding extruded compound feed. Background technique [0002] There are more than a dozen varieties of mandarin fish in my country. Among them, the cocked mandarin fish is favored by consumers because of its fast growth rate, strong adaptability to the environment, and fresh and tender meat. It has high economic value and is the most important mandarin fish cultured species. Mandarin fish is a ferocious carnivorous animal. It feeds on live fish and shrimps all its life from the larvae, and the bait coefficient is usually above 4. It usually needs to be equipped with live fish bait breeding facilities that are more than 4 times that of mandarin fish, and the live fish bait will carry Various viruses cause mandarin fish to be extremely susceptible to disease, which greatly limits the large-scale production of mandarin fish. [0003] The existi...
