Embodiment 1

[0027] Such as figure 1 shown.

[0028] A kind of opening domestication method of mullet fry or yellow catfish fry, it comprises the following steps:

[0029] First, put the newly hatched fry into an acclimatization pond with a width of no more than 40 cm and a length of no more than 6 meters (such as figure 1 shown), control the water depth to no more than 15 cm, and control the flow rate of water in the acclimatization pool so that the fry attached to the pool wall will not be washed away by the water; it is best to install the acclimatization pool in a greenhouse, and control the ambient temperature of the greenhouse at the same time. Between 28-30°C; the stocking plan for each domestication pond is 20,000 to 100,000 fish, the longer the length, the number of tails that can be stocked will increase accordingly; the water in the domestication pond should be purified and disinfected with earthen pond water, so that it can be compared with fry In order to prevent the lack of...

Embodiment 2

[0035] Such as figure 1 shown.

[0036] A fish fry opening acclimation device, which includes several supports 8 installed in the thermal insulation greenhouse 9, the thermal insulation greenhouse 9 is preferably equipped with a temperature control device to ensure that the temperature of the greenhouse is 28-30 ° C, and the number of brackets 8 installed in each greenhouse can be Calculate and determine based on production. Several domestication pools 1 are installed from top to bottom on each support 8, the width of the domestication pool 1 is no more than 40 cm, the length is no more than 6 meters, the height is no less than 20 cm, and the water depth is between 10-15 cm. Between, one end of acclimation pool 1 is provided with drainage groove 2, is provided with retaining seedling net 3 (mesh diameter should be able to stop fry to pass through) on drainage groove, one end of drainage groove 2 is airtight, and the other end is connected with drainage pipe 12, and drainage p...

Abstract

The invention relates to a method and device for acclimatizing opening of fish fries. The method is characterized by comprising the following steps: firstly, putting just-hatched fish fries into acclimatization pools, of which the width does not exceed 40cm and the length does not exceed 6m, and controlling water depth not to exceed 15cm, and controlling the flow velocity of water in the acclimatization pools in a manner that the fish fries attached to pool walls are not washed away by the water; and meanwhile, controlling the environmental temperature of the acclimatization pools to 28 DEG C to 30 DEG C, wherein the stocking density of each acclimatization pool is 100,000 to 200,000 tails; secondly, feeding the fish fries by taking rotifer or Artemia salina as feedstuff for opening 2 to 3 days after the fish fries come out, wherein the feeding amount of the rotifer or Artemia salina is 5g per 10,000 tails; thirdly, taming to feed on artificial feed 2 to 3 days after the rotifer or Artemia salina is fed; and fourthly, ending acclimatization one week after the artificial feed is fed, and carrying out culture on the fish fries in culture ponds. The method disclosed by the invention is simple, and the survival rate is high. A basis for industrialized fry rearing is laid.

Description

technical field [0001] The invention relates to an aquaculture technology, in particular to a fish fry culture technology, in particular to a fish fry opening domestication method and a domestication device. Background technique [0002] As we all know, mullet, yellow catfish and perch are carnivorous fish. Due to the lack of corresponding bait in nature, the survival rate of fry is low, and they are not suitable for large-scale factory farming. Therefore, their feeding habits must be changed from an early age , in order to change the feed during the growth process, so as to realize the cultivation in the round pond of the greenhouse. For this reason, people have carried out a lot of explorations, but cause domestication rate is not high because of lacking suitable domestication device and method for a long time, after entering culture pond, because do not adapt to feed and survival rate is not high, have a strong impact on the development of aquaculture. Therefore, inventi...
