Description
Technical field
The present invention relates to cultural technique field more particularly to a kind of cultural methods of rainbow trout.
Background technique
Rainbow trout belongs to a kind of salmon that salmon shape mesh salmonidae Pacific Ocean salmon belongs to.Rainbow trout is favored due to delicious flavour and by people,
Usually contain helminth in wild rainbow trout, since rainbow trout is by the way of eating it raw, helminth can threaten people in rainbow trout
Health, although now also using artificial breeding rainbow trout, the either water of most of or lakes using nature
Stream, is still open cultivation, and birds droppings is easy to fall in aquaculture pond, increases the helminth in aquaculture pond, and the bait launched
The most small fish shrimps etc. to draw materials nearby of material, although improving yield, the edible safety of rainbow trout still cannot be guaranteed.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and a kind of cultivation side of the rainbow trout proposed
Method.
To achieve the goals above, present invention employs following technical solutions:
The cultural method for designing a kind of rainbow trout, includes how step:
The construction of S1, fishpond: being built into specification rectangle cement of the same size fishpond using concrete, cement fishpond
Depth is 80-110 centimetres, and multiple cement fishponds, according to matrix arrangement, cement fishpond bottom is arranged to the slope of 1/50-1/100
Degree；
The environmental requirement of S2, fishpond: fresh water is added into cement fishpond, and the depth of water is 20-40 centimetres, the requirement model of water temperature
Enclosing is 7-20 degrees Celsius, and the dissolved oxygen amount of water is 6-10 mg/litre, and water colour wants as clear as crystal, and the coloration of water will be lower than 30 degree, in water
Suspended matter be less than 15 mg/litres；
S3, fishpond protective device are built: bird-scaring unit being mounted equidistant around cement fishpond, and take on cement fishpond
Support frame is built, fixation is supported by transparent shading cloth on support frame；
The dispensing of S4, fry: it selects physical strong, neat specification, thrown without wound and disease-free Triploid Rainbow Trout fry
Put, and the breeding density of larval rainbow be 5000-10000 tail/square metre；
The preparation of S5, feed: the animal raw materials of fresh high protein are chosen after high-temperature sterilization treatment and coarse food grain
Bait is made in mixing, and animal raw materials in the different growth stages of rainbow trout, bait and coarse food grain ratio are appropriate
It is adjusted；
S6, daily aquaculture management: being directed to larval rainbow, feeds daily primary, for rainbow trout adult fish, feeds 2 times daily, often
It daily ration, feeding quantity is calculated with the weight of fish, and the daily daily ration, feeding quantity of larval rainbow accounts for the 3%-4% of own body weight, rainbow trout adult fish is every
It daily ration, feeding quantity accounts for the 1%-2% of own body weight；
S7, rainbow trout point pond raise: when the weight of larval rainbow reaches 0.5-2.5 grams (4-6 centimetres of overall length), need by
Larval rainbow is raised according to the difference point pond of Individual Size, breeding density at this time be 1200 tails/square metre, depth of water 40-60
Centimetre, when the weight of rainbow trout reaches 20-30 grams, need to carry out a point pond to rainbow trout again, at this time rainbow trout put in a suitable place to breed it is close
Degree be 500 tails/square metre, the depth of water be 60-80 centimetres；
The maintenance management of S8, fishpond environment: periodically clearing up cement fishpond, keeps the matter of water quality in cement fishpond
Amount finds that sick fish will take remedy measures immediately, and the dead fish in cement fishpond will be rejected in time.
Preferably, in step sl, it is equipped with connection water pipe between two neighboring cement fishpond, pacifies on each cement fishpond
Equipped with water-changing tube, the Aspect Ratio in rectangle cement fishpond is 1:5-8.
Preferably, in step s 4, larval rainbow will carry out disinfection processing before dispensing.
Preferably, in step s 5, the animal raw materials of high protein include small fish, shrimp, pluck, pig blood, silkworm
Pupa, earthworm etc., coarse food grain includes soya-bean cake, flour, corn, bran etc., and for larval rainbow, animal raw materials account for 60%, for rainbow
Trout adult fish, animal raw materials account for 50%, and minerals and vitamins are also added in bait.
A kind of cultural method of rainbow trout proposed by the present invention, beneficial effect are: the present invention is completely using artificial breeding
Method individually raises rainbow trout using individual cement fishpond, and high for the environmental requirement in cement fishpond, gives
The growth of rainbow trout provides a healthy growing environment, and the setting of bird-scaring unit and transparent shading cloth, can prevent bird dung from falling
It drops into cement fishpond, and then can prevent the helminth in bird dung from entering in cement fishpond, and the preparation of bait is to adopt
It is mixed with the animal raw materials of high protein and coarse food grain, wherein also added minerals and vitamins in bait, it can be effective
Raising rainbow trout nutritional ingredient, and animal raw materials still pass through high temperature process processing, can be good at preventing rainbow trout
In there is helminth, can effectively ensure that the safety that people eat.
