Problems solved by technology

[0005] The purpose of the present invention is to select artemia of appropriate size after indoor artificial cultivation and nutritional strengthening of Artemia, and keep 24h light during the opening period to realize the use of non-live bait fish under controllable conditions for opening the mouth of mandarin mandarin fish, which makes up for the supply of bait fish It not only solves the problem that the supply of bait fish for mandarin fish with upturned mouth in aquaculture is limited by factors such as season, nutrition, price, etc., but also solves the difficulty of feeding live bait fish in the fry stage of mandarin fish. Infecting pathogens and causing subsequent disease outbreaks during the mandarin fish domestication stage contributes to the green and healthy development of mandarin fish farming

Embodiment 1

[0027] The effect of halochidia on the feeding and survival rate of the tipping of the tipped blender:

[0028] 1) The rooms of the tipped fish are controllable manual hatching and cultivation: squid is placed in a year after aeration, the density is 300-500 pieces / L, full aeration makes the squid affair eggs in the water body. Change water once a day and draw the dead eggs and impurities to ensure water quality. After the fisherna out of the film, a large amount of oil film will be generated. At this time, 3 times should be treated 3 times a day, and the ovasses and impurities should be absorbed to ensure water quality. After the fishermen is limited, the impurities and flocs in the water body must be removed in time to avoid death.

[0029] 2) Incubation and expansion of haloquis: Take commercialized halide eggs, incubation in a water body having a salinity of 10-12 ‰. After incubating the hatchilla, it is placed in a water body having a salinity of 20-25 ‰, and the density of...

Embodiment 2

[0035] The effect of lighting on the hair of the halves of the tipped fish:

[0036] The squid in the fourth day of the removal film was divided into 2 groups. The light and dark time ratio of the control group was 12 h: 12h, the experimental group was 24h light, and the two groups were 800-900μm, and 3 repetitions per group. The cultivation method of the squid is carried out in Example 1. Feeding the haloctorma once a day, 8:00 and 18:00, the water temperature is 23-25 ​​° C, and the bait and feces are taken out before the feed, and the water is 1 / 3, and the water is fresh. The method and survival rate of the tipped bisquis were statistically statched according to Embodiment 1. Result analysis: Image 6 As shown, the lighting can significantly improve the food rate of the warpone to the haloquin and the survival of the survival after the feeding, and the food group of the 24h light group is 63.33% ± 3.33, while the probiotikisi of the control group The food rate of insect is 53.33...

Embodiment 3

[0038] A gentle tubular fishing method of indoor controllable non-live bait fish, which includes the indoor controlled manual cultivation and nutritional reinforcement of the halogency, and the halocetis is used in the fisherd feeding, the specific method is as follows:

[0039] 1) Chamber-controlled artificial cultivation and nutrient enhancement of halide

[0040] 1.1 The haloquinum is incubated in a salinity of 10-12 ‰ Hydrostation, and the water salinity of the cultivating halide is controlled at 20-25 ‰, and the salt must be sea salt, the halide density is 50-80 / ml;

[0041] 1.2 The length of the haloctis in the artificial cultivation can reach 400-900 μm, which is to discover the halide and eat;

[0042] 1.3 After the shell of the haloctormidium, the nutrient reinforcement is started, and the content of EPA and DHA in the fatty acid composition of the halide in 16-24 h are strengthened, and the content of DHA is significantly higher than that of unopened halide.

Abstract

The invention provides an indoor controllable non-live bait fish opening method for cultivating cocked mandarin fish. After the 4th day after the cocked mandarin fish emerges from the film, artemia with a length of 700-900 μm that has undergone nutrition fortification is used as mandarin fish The opening bait of the mandarin fish was kept open for 24 hours, and the salinity of the breeding water was 3‑5‰ during the period when the mandarin fish opened its mouth to eat Artemia. The present invention is the first time that non-live bait fish is used for open mouth feeding of mandarin fish with cocked mouth under indoor controllable conditions. Artemia with enhanced nutrition and a length of 700-900 μm is beneficial to feeding and digestion and absorption of mandarin fish. 24 h light treatment is adopted After that, the survival rate and feeding rate of mandarin fish can be significantly improved. This method not only improves the survival rate of mandarin fish with cocked mouth when they open their mouths, but also reduces some diseases caused by bait fish. reliable technical support.

Description

Technical field [0001] The invention belongs to the field of aquaculture fry frying, and in particular, the present invention relates to a method of cultivation of open bait (halochi) for warping of non-live bait fish. Background technique [0002] The squid is naturally distributed only in East Asia (Russia, Japan, South Korea, China and Vietnam (Honghe)), which is the main farming known fish. The main breeding variety of the bold fish is a nose, and the supply of the opening bait is insufficient or delayed to make the survival rate of the early developmental stages of the squid and slow growth. Therefore, in artificial breeding, how to provide nutritious and well-equipped bait for rumizers, is the key to the success of cultivation. Although the artificial reproduction and breeding of squid have been initially successful, the production of squid seedling has little production, and is mainly based on the production of bait fish (squid, squid, squid and squid). And the supply of b...
