Problems solved by technology

[0004]However, the above scheme is not practical for carp. In the breeding habits of carp, early reproduction of carp needs to massage its abdomen. At the same time, the temperature suitable for carp reproduction must be ensured , therefore, we need to provide a method of raising fish fry with high survival rate to be suitable for carp early breeding

Embodiment 1

[0035] Basic as attached figure 1 And attached figure 2 Shown, a kind of fish fry raising method that survival rate is high, comprises: Step 1: choose one terrain flat outdoors, sunny, the place of water source is clear, pollution-free, builds an area of ​​10-12 mu, water depth 1.5-2 meters Spawning pool 3; Step 2: Get the body surface without trauma, normally eat the pregnant female carp; Step 3: Lay a protective film 4 with a rough surface at the bottom of the spawning pool 3, and the roughness of the protective film 4 is 6.3; Step 4 : Disinfect the spawning pool 3, then put the interior of the spawning pool 3 into water; Step 5: put the selected female carp into the built spawning pool 3;

[0036] Step 6: Tie the fish grass into a circle and place it inside the spawning pond 3; Step 7: Install an electric water heat pipe inside the spawning pond 3, and control the electric water heat pipe to 20-25°C to urge the female carp to spawn; step Eight: put feed in the spawning p...

Embodiment 2

[0043] Basic as attached image 3 As shown, different from Embodiment 1, the bottom wall of the spawning pool 3 is inclined, and the bottom wall of the spawning pool 3 is inclined to the middle, and the bottom of the spawning pool 3 is provided with a water outlet, and the water outlet is located in the spawning pool 3 the middle of the bottom wall, that is to say, the water outlet is the lowest point of the bottom wall. Just below the spawning pond 3 is provided with a dustbin 10 for collecting fish excrement. The dustbin 10 communicates with the water outlet through a feeding pipe 11. The feeding pipe 11 is provided with a filter screen 12, which can pass water and excrement, etc. , At the same time, it prevents the fry from passing through. In order to clean up the rubbish on the filter screen 12, the filter screen 12 is detachably installed inside the drop pipe 11, that is, the filter screen 12 both sides can be pasted (no pollution to water quality and fry) on the side w...

Embodiment 3

[0047] Basic as attached Figure 4 As shown, different from embodiment 2, the spawning pond 3 is provided with a first cylinder 15, and the left side wall of the first cylinder 15 is fixed on the left side wall of the spawning pond 3, and the first cylinder 15 is located on the spawning pond 3. At the upper left corner of the egg pool 3 and submerged by water, the inside of the first cylinder 15 is provided with a first piston 16 that is slidably connected, and the first piston 16 divides the inside of the first cylinder 15 from left to right into a first cavity and a second cavity. Cavity, the first spring 17 is arranged between the first piston 16 and the side wall of the first cavity, one end of the first push rod 18 fixedly connected is arranged on the right side of the first piston 16, and the other end of the first push rod 18 Fixedly connected with the slide rod 7, the first push rod 18 runs through the entire first cylinder 15, the slide rod 7 is provided with a plural...

Abstract

The invention belongs to the technical field of aquatic product breeding, and particularly discloses a high-survival-rate fry breeding method which comprises the steps that 1, a spawning pond is built outdoors; step 2, taking female carps which have no body surface trauma and are normally fed and fertilized; 3, laying a protective film with a rough surface at the bottom of the spawning pond; 4, disinfecting the spawning pond, and then putting water into the spawning pond; 5, the selected female carps are put into the built spawning pond; 6, binding the fish grass into circles, and placing the circles in the spawning pond; 7, installing an electric water heat pipe in the spawning pond, and controlling the temperature of the electric water heat pipe to be 20-25 DEG C to promote the female carps to spawn; 8, feed is put into the spawning pond, the weight of the feed put each time is 100-120 g, and the feed is put four times a day; 9, the fish grass with the fish eggs penetrates through a tree trunk, water is sprayed once every three hours and lasts for three days, the water needs to be sprayed thoroughly and evenly, and the fish eggs are prevented from being dried and dewatered and wait for incubation. According to the scheme, the early breeding rate of carps is high.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for raising fish fry with high survival rate. Background technique [0002] The natural breeding of fish means that after the beginning of spring every year, the temperature rises, and the female fish will lay eggs, and by hatching the eggs, they will reproduce and hatch new fry. Most fish farming enterprises rely on natural breeding to incubate new fry. For the fry bred through natural breeding, the time when the fry of each company is mostly on the market is not much different. In the early days, many other companies needed a large number of fry, which made the sales of fry that went on the market earlier the better, and the unit price of fry was higher. [0003] The Chinese patent with the publication number CN109349173A discloses a breeding method for improving the survival rate of grouper fish fingerlings, including indoor seedling cultivation and outdoor seed...
