Description
Technical field
The present invention relates to fish culture technical field more particularly to a kind of high yield cultural methods of fresh-water fishes.
Background technique
Fish is one of animal common in people's daily life, some breedings have ornamental effect, and some fingerlings are often made
It is all normal on dining table that the good merchantable brand, such as crucian, grass carp, silver carp, perch, catfish in fresh-water fishes etc. of dish are made for people
Product.But we when buying fresh-water fishes, it can be seen that its price of the fresh-water fishes of same breed is there is also certain difference, size
Different, meat differences will affect the price of fresh-water fishes.And the most important influence factor that the size of fish, meat have differences
It is exactly the breeding environment and cultural method of fresh-water fishes.Reasonable breeding environment and cultural method can accelerate the growth of fish, improve
Flesh quality improves the yield of fish.Based on this, the present invention proposes a kind of high yield cultural method of fresh-water fishes.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and a kind of high yield of the fresh-water fishes proposed
Cultural method.
A kind of high yield cultural method of fresh-water fishes, comprising the following steps:
S1, fingerling select: select an age fish physical strong, neat, disease-free, that motoricity is strong as fingerling, it is spare；
S2, improvement crawl: first carrying out sterilizing to crawl, while uniformly installation water pump and heater, and sterilizing 2~
After 3 days, according to silt soil, laterite and turfy soil mass ratio be 40~60:15~25:10~20 weigh silt soil, laterite and
Turfy soil, and weighed silt soil, laterite and turfy soil are uniformly mixed, improvement silt soil is obtained, then puts down improvement silt soil
Crawl bottom after being laid on sterilizing, laying depth are 15~20cm, then apply compound fertilizer, overlay film 1 to improvement silt soil surface
Film is taken after~2 days, water plant is added into crawl, adding water to the depth of water is 1.2~1.5m, is added using heater to water temperature
Heat, controlling the water temperature in crawl is 18~23 DEG C, completes the improvement of crawl；
The dispensing of S3, fingerling: the fingerling that step S1 chooses is launched into the crawl after step S2 improvement, and according to daily 6~8
It is secondary to carry out feeding fish meal, and it is standard that the injected volume of fish meal, which eats up migration according in crawl 75%~80% fish, to fish
Daily 4 fishes of dispensing are gradually decreased to according to the impressions for reducing by a fish meal weekly when kind weight length is to 2 times when launching to raise
Material, and the standard for launching 4 fish meals daily to fresh-water fishes is kept to harvest；
Maintenance in S4, breeding process: a water pump is opened every 5~8h, is patrolled daily crawl, and every 30~35
It is shed worm for fishing to crawl and kills star, and dosage is 20~30ml per acre, while salvaging excessive water plant and sick fish, periodically to breeding fish
Pond is filled the water, winter every water of 10~15 days notes, summer every water of 5~10 days notes, until the fingerling in crawl
Maturation can harvest, and complete the high yield cultivation of fresh-water fishes.
Preferably, the type of the fingerling be crucian, carp and silver carp in any one, and fingerling be crucian when fingerling
The a length of 5~6cm of body, fingerling be carp when fingerling a length of 3~4cm of body, fingerling be silver carp when fingerling a length of 2~3cm of body.
Preferably, the compound fertilizer includes the raw material of following parts by weight: 50~60 parts of the decomposed excrement of people and animals, decomposed stalk 20
~30 parts, 4~8 parts of urea, 1~2 part of ammonium hydrogen carbonate, 2~4 parts of monoammonium phosphate, 0.5~1.5 part of mineral composition, EM bacterium
0.02~0.03 part, 50~60 parts of water.
Preferably, the compound fertilizer includes the raw material of following parts by weight: 55 parts of the decomposed excrement of people and animals, 25 parts of decomposed stalk,
6 parts of urea, 2 parts of ammonium hydrogen carbonate, 3 parts of monoammonium phosphate, 1 part of mineral composition, 0.025 part of EM bacterium, 55 parts of water.
Preferably, the usage amount of the compound fertilizer is 460~520kg per acre.
Preferably, the throw-in density of the fingerling is according to crucian 800~900 tails, carp 1000~1200 tail per acre per acre
Or silver carp per acre launched by 1200~1400 tails.
Compared with prior art, the invention has the benefit that
1, the cultural method that this law invention proposes, is picked up since fingerling, to guarantee that high yield harvests fresh-water fishes；
2, crawl is improved, is respectively controlled from breeding fish with the amount of oxygen in soil, temperature of breeding fish, crawl, to protect
The growing environment that card fingerling is suitable in the breeding process, accelerates the growth of fingerling, the yield of fresh-water fishes is improved, with rational proportion
Silt soil, laterite and turfy soil are fingerling cultivation soil, then cooperate the adjustment of the compound fertilizer of rational proportion, to improve soil fertilizer
Power provides nutrient for the growth of fingerling, then cooperates the addition of water plant, can also both may be used to provide certain oxygen in crawl
To consume the carbon dioxide in water, crawl water body environment is purified, provides guarantee for fingerling growth；
3, the regular of water pump opens the content that can have both improved dissolved oxygen in crawl water body in breeding process, while can also promote
The fingerling of crawl is moved, and to improve flesh of fish matter, improves the mouthfeel of fish, makes tasty mouthfeel, the smooth and tender meat quality of adult fish, into
And improve the selling price of fish；
4, feed feed and maintenance work, it is ensured that the environment of fingerling growth reduces injury of the sick fish to healthy fingerling,
And then improve the yield of fresh-water fishes.
