Description
Technical field
The present invention relates to aquaculture technical field, especially a kind of rainbow trout cultural method.
Background technology
Rainbow trout, a kind of salmon of category salmon shape mesh salmonidae Pacific Ocean salmon category.Largest body is long：120cm, perches depth：0~5 meter,
It is described as " ginseng in water ".It is good at jump, fierceness is striven after rising to the bait.Draw from Western North America and grow to many countries.Dwell in lake and
Torrent, body colour is bright-coloured.Small blackspot is furnished with body, there is a red zone on side, such as rainbow, hence obtained one's name " rainbow trout ".
Rainbow trout originates in North America pacific rim, in the mountain stream in North America, river.Like to inhabit limpid, water temperature relatively low, molten
The waters that oxygen is more, flow is abundant.Rainbow trout belongs to carnivorous.Juvenile stage is with zooplankter.Zoobenthos, aquatic insect are
It is main；Adult fish is using fish, shell-fish, shellfish and terrestrial and aquatic insect as food, also drinking water plant leaf and seed
Rainbow trout delicious meat, consolidation are delicate, are pierced between no flesh, and protein content is high, cholesterol level is low, rich in abundant ammonia
Base acid and unrighted acid and deep liked by common people.Current rainbow trout industrialized cultivation method is also in primary rank
Section, water quality and temperature are often difficult to be protected, and feed nutrition is also unbalanced, so as to influence the meat of rainbow trout, causes rainbow trout
Fish tissue protein content declines, and survival rate declines, and flesh quality is undesirable, and exists in the feeding process of rainbow trout and survive
The problem of rate is relatively low, in order to improve its resistance against diseases and survival rate, often adds the chemicalses such as Multiple Classes of Antibiotics in feed,
It can cause the presence of many medicament residues in the flesh of fish, it is unfavorable to human body.Rainbow trout survival rate is put forward therefore, it is necessary to provide one kind
Height, and the rainbow trout cultural method of the good no chemical residues of flesh quality is kept, carried under conditions of rainbow trout is propagated artificially
The meat of high rainbow trout, promotes growth, improves grazing rate and immunity, creates higher economic benefit.
The content of the invention
In order to solve above-mentioned technical problem present in prior art, the present invention provides a kind of rainbow trout cultural method, tool
Body technical scheme is that：
(1) pond is built：Set up flowing water culture pond, it is desirable to without silt, more than depth of water 1m, a length of 20-30m in pond, a width of 3-
6m, depth is to fall path difference between 1-2m, Chi Yuchi for 0.8-1.2m, and high order end sets water inlet, and low order end sets out the mouth of a river, each mouth of a river
On be equipped with fence and screen cloth；There is path difference between Chi Yuchi；Connected between Chi Yuchi by solid stream of water；
(2) environmental requirement：Water temperature is controlled at 7-22 DEG C；It is 5-8 ‰ to control water salinity；Dissolved oxygen is controlled in more than 6mg/L,
The flow velocity for controlling water is 12-18 ms/min；Water cleaning is pollution-free without silt；Preferred ambient is control water temperature at 12-18 DEG C；
Dissolved oxygen is controlled in more than 8mg/L, and other are constant, and the activity of rainbow trout is more active in preferred ambient, and the speed of growth is faster.
(3) seedling is put：Xiang Shuizhong delivers larval rainbow, and the optimal selection raised as meat fish is to deliver Triploid Rainbow Trout fish
Seedling, Triploid Rainbow Trout fish is the gynoecy rainbow trout that tetraploid rainbow trout and the hybridization of common diploid rainbow trout are produced.With life
Long period is short, and cost is low, the characteristics of meat is good, is cultivated using complete female Triploid Rainbow Trout fish, can improve rainbow trout survival rate
10%, the speed of growth 10-20% can be improved and the excessive consumption because of gonad development to feed can be avoided, reduction is cultivated into
Sheet more than 5%, can improve overall economic efficiency 15%~20%；
(4) prepared by feed：Daily fed feed is the herbal health care addition that 5%-15% is added in common feedstuffses
Agent and 40%-60% insect protein additive are well mixed to be formed.The herbal health care additive is by following parts by weight
Raw material composition：Honeysuckle 30~40, the fruit of Chinese wolfberry 15~25, reed rhizome 20~30, reticulate millettia 15~25, the Radix Astragali 10~15, hawthorn
12~17, this herbal health care additive has the albumen synthesis promoted in serum, marrow, organ, resists free radical to body
The infringement of middle protein and fat, hinders protein in body content, improves its fish body immunity and promote effect of shoal of fish appetite.Institute
It is insect protein fresh goods or insect albumen powder to state insect protein additive.Such as maggot fly, yellow meal worm, Asiatic migrotory locust or silkworm chrysalis insect
Fresh goods is processed into insect albumen powder, substantial amounts of bioactivity " enzyme " is rich in insect protein, rich in chitin, lecithin etc..
Brain cell, nervous system, the thinking of the mankind, memory and control muscular movement etc. are all of great benefit to.Using insect protein as
The feed of rainbow trout, can convert it to the edible protein of most people receiving so that rainbow trout meat quality of fish and nutritive value are obtained
It must be lifted, and the same function with insect protein of the rainbow trout flesh of fish of coming out cultivation
(5) daily aquaculture management：During cultivation, feeding 4 times need to be thrown daily, daily total feeding amount of throwing is based on fish body weight 3%-15%
Calculate, fed with throwing to raise to arrive without striving food phenomenon i.e. stopping, should detecting that fish is heavy every 1-15 days, specifically feeding ratio can basis
Shoal of fish situation is adjusted.
Compared with prior art, the technique effect of the invention is embodied in：
The method fed using the addition Chinese herbal medicine in feed and insect protein mixing is cultivated to rainbow trout, to add
Medicinal herb componentses strengthen fish body immunity and promote shoal of fish appetite；Using insect protein as rainbow trout primary protein source, make
The rainbow trout build that must cultivate out is big, energetic, and meat fine and smooth lubricious, protein content are high and containing big in insect protein
Most nutritional ingredients.
