Embodiment 1

[0027] like figure 1 Indicated.

[0028] One kind or black catfish fry seedlings domesticated opening method, comprising the steps of:

[0029] First, the newly hatched fish into a width not exceeding 40 cm and a length of not more than 6 meters pool domesticated (e.g. figure 1 Shown), controls depth of not more than 15 cm, and controlling the flow rate of water in the pool so that domesticated fry deposited on the wall is not washed away; is preferably mounted in the greenhouse acclimatization cell while controlling the temperature in the greenhouse between 28-30 deg.] C; stocking density of 2-10 per ten thousand domesticated cell, the longer the length, a corresponding increase in the mantissa can be stocked; application of soil water pond water purification and disinfection acclimation tank, so that the fish the emergence adapt to the environment, in order to prevent hypoxia acclimation pool, water aerobics should be added, so that the oxygen content in water is not less than t...

Embodiment 2

[0035] like figure 1 Indicated.

[0036] One kind of domesticated fry opening means, which comprises a plurality of brackets mounted on the insulation shed 8 9, temperature control device 9 is preferably attached to heat greenhouses, guaranteed greenhouse at a temperature of 28-30 deg.] C, each number of sheds mounting bracket 8 may be The calculated yield is determined. Each bracket 8 is mounted from top to bottom with a plurality of acclimation tank 1, the width of the domesticated cell 1 does not exceed 40 cm and a length of not more than 6 meters, a height of not less than 20 cm, the depth of 10-15 cm Room cell 1 is provided with an end domesticated drainage grooves 2, disposed on the drain stopper groove 3 seedlings net (mesh diameter can be prevented by fry), the closed end of the drainage grooves 2, and the other end connected to a drain pipe 12, drain the height of the outlet 12 is adjustable to adjust the height of the pond water level domesticated, drain water discharged...

Abstract

A fish fry opening domestication method and domestication device are characterized in that the method includes the following steps: first, put the newly hatched fish fry into a domestication pond with a width of no more than 40 cm and a length of no more than 6 meters, and control the water depth to no more than 6 meters. over 15 cm, and control the flow rate of water in the acclimation pond so that the fry attached to the wall of the pond are not washed away by the water; at the same time, the ambient temperature of the acclimatization pond is controlled between 28‑30°C; the stocking plot of each acclimation pond is 10 ‑200,000 fish; secondly, rotifers or Artemia are used as opening bait 2‑3 days after fry emergence, and the feeding amount of rotifers or Artemia is 5 g / 10,000 fish; thirdly, rotifers are used Or feed the artemia for 2-3 days and then domesticate and feed the artificial feed; fourth, after feeding the artificial feed for one week, the domestication can be completed, and the fry will be sent to the breeding pond for breeding. The method of the invention is simple and has high survival rate. It laid the foundation for industrial seedling cultivation.

Description

Technical field [0001] The present invention relates to a technique for aquaculture, in particular a fish farming techniques, in particular to a method and domesticated domesticated fry opening means. Background technique [0002] As we all know, mullet, catfish and perch is a carnivorous fish, nature due to lack of appropriate food which led to lower survival rate of fry, not suitable for large-scale factory farming, it is necessary to change its feeding habits from an early age , during the growth process in order to change to feed the feed, in order to achieve a circular greenhouse ponds. For this reason, a lot of people to discover, but the long-term due to the lack of suitable devices and methods which led to the domestication domesticated rate is not high, into the pond and feed due to not meet the survival rate is not high, seriously affecting the development of aquaculture. Accordingly, invent a mullet, perch and catfish opening acclimatization method and apparatus is the...
