Problems solved by technology

[0005] The above existing technologies all stay at the stage of experimental results, and are cultivated in an incubator. The bait is rotifers and small cladocerans. This is only suitable for small-scale seed cultivation, and the cultivation cost is high, so it cannot adapt to large-scale production at all. need

Embodiment 1

[0031] Embodiment 1: the artificial seedling raising method of pedunculus and the application in large-scale cultivation of pedunculus, include but not limited to the following steps:

[0032] a. Preparation of the cultivation pond: first clean and disinfect the cultivation pond;

[0033] b. Fertilization water quality: before the fry enter the pond, the water body in the cultivation pond is fertilized;

[0034] c. Putting in the seedlings: put the artificially hatched fry into the breeding pond when they start to have the ability to swim;

[0035] d. Breeding pool management: According to the growth needs of fry, add fertilizer to the breeding pond and adjust the water level of the breeding pond in time;

[0036] e. Divide ponds: When the fry grow to 3-5 cm, divide them into ponds;

[0037] f. Fry out of the pond: When the fry grow to 7-8 cm, they come out of the pond and enter the cage for adult fish breeding or free-range breeding.

Embodiment 2

[0038] Embodiment 2: the artificial nursery method of pedunculus and the application in the large-scale cultivation of pedunculus include but not limited to the following steps:

[0039] a. Site selection for breeding ponds: select ponds in the plains or lakes downstream of the origin of the horse mouth fish as the breeding ponds;

[0040] b. Cultivation pond preparation: first clean and disinfect the cultivation pond;

[0041] c. Fertilization water quality: Fertilize the water body in the cultivation pond before the fry enter the pond;

[0042] d. Putting in the fry: put the artificially hatched fry into the breeding pond when they start to have the ability to swim;

[0043] e. Breeding pool management: According to the growth needs of fry, add fertilizer to the breeding pond and adjust the water level of the breeding pond in time;

[0044] f. Divide ponds: When the fry grow to 3-5 cm, divide them into ponds;

[0045] g. Fry out of the pond: When the fry grows to 7-8...

Embodiment 3

[0047] Embodiment 3: the artificial seedling raising method of larvae and the application in the large-scale cultivation of larvae comprise the following steps:

[0048] a. Cultivation pond preparation: choose the field mud pond as the cultivation pond, the depth of the pond is 1.5m, first remove the sundries and sludge in the cultivation pond, and then disinfect it with quicklime.

[0049] b. Fertilization water quality: Fertilize the water body in the cultivation pond before the fish fry enter the pond, and sprinkle 10 kg of fermented livestock fertilizer per mu.

[0050] c. Put in the fry: put about 500 fry per cubic meter of water body when the artificially hatched fry start to have swimming ability, and control the water depth in the breeding pond at 30-40cm.

[0051] d. Nurturing pond management: According to the growth needs of fish fry, increase fertilizer and adjust the water level of the cultivating pond in time; said fertilization: when the plankton in the cultivati...

Abstract

The invention provides an artificial Chinese hooksnout carp breeding method and application in large-scale Chinese hooksnout carp breeding, relates to an artificial wild river fish breeding method, in particular to a Chinese hooksnout carp fry breeding method. The method includes but is not limited to the following steps that (a) a breeding pond is prepared, wherein the breeding pond is cleaned and subjected to disinfection treatment; (b) water is fertilized, wherein a water body in the breeding pond is fertilized before fry is put in the pond; (c) the fry is put, wherein the artificially hatched fry is put in the breeding pond when having the swimming ability; (d) the breeding pond is managed, wherein a fertilizer is added to the breeding pond according to the demand for fry growth in time, oxygen increase is performed, and the water level of the breeding pond is adjusted; (e) pond separation is performed, wherein the pond separation is performed when the fry grow to reach the length of 3-5 cm; (f) the fry is taken out of the pond, wherein the fry is taken out of the pond and put in a net cage for adult fish breeding or free ranging when the fry grow to reach the length of 7-8 cm. The breeding method is simple and practical, the survival rate of the fry is high, the breeding cost is low, large-scale production can be performed, the bred Chinese hooksnout carp yield is high, the quality is good, and an ecological system of a mountainous area river can be rapidly restored.

Description

technical field [0001] The invention relates to a method for artificially breeding wild river fish, in particular to a method for cultivating larvae fry. Background technique [0002] The horse mouth fish is commonly known as May Red or Red Chegong in the south. It is a wild fish that lives in small rivers and streams with good water quality. It inhabits the upper layer of the water area and likes low temperature water quality. Small fish and aquatic insects feed on them. Although the largest individual is only 20cm, they are rich in nutritional value and delicious in taste, and are very popular with consumers. Now, wild fish are becoming less and less, and it is difficult to see them in the market. Therefore, people have seen the economic value of artificial breeding of horse mouth fish from the gradual disappearance of natural resources, and various research results have also emerged from time to time. [0003] For example, Jiang Jingtian, Experiments on Artificial Propag...
