Description
Technical field
The present invention relates to aquaculture technical field, especially a kind of spot Of-digestive-tract cultural method.
Background technique
Spot Of-digestive-tract (Mystus guttatus) is subordinate to siluriformes, Chang section, Of-digestive-tract category, is commonly called as spot Of-digestive-tract, Zhi Ma Han, Bai Xu Han, west
Jiang Han, Hua Han, body are in yellowish-brown, and thorn is a little, and fish is similar to sword, are covered with the black splotch of sesame seed size with it, therefore and gain the name；
The fish is distributed in the water systems such as the Zhujiang River, Yuanjiang River, Jiulongjiang River, Han Jiang, the Qiantang River, has a sweet temper, and whole body is slided without squama, fine and tender taste, skin
Meat is refreshing, delicious, and nutritive value is high, is known as the hat of four big fishes of the Zhujiang River (spot Of-digestive-tract, flower perch, Met roller, mandarin fish), enjoys " light
The good reputation of water fish king ", the market price is up to 80 yuan/jin or more.In south, the domestic river in Yunnan Luodian County, Pearl River system Guangxi border
It is interior work in peace and contentment, the left rivers section in the Hongsuihe River between two county of Tiane and the town Yang Meigu produces wild spot Of-digestive-tract.
In recent years, due to the influence of the factors such as building of irrigation works, overfishing and water pollution, the habitat wild spot Of-digestive-tract
Environment is seriously damaged, and stock number sharply declines, and is distributed in scattered shape, and the market demand is being continuously increased, artificial breeding
It has been attracted people's attention that, and gradually had developed.Fatty acid and amino acid are the important nutrition of fish normal growth and development
Substance, spot Of-digestive-tract different developmental phases (juvenile fish stage, adult fish stage and parent population stage) to the demands of various nutritional ingredients and
There are difference, current spot Of-digestive-tract cultural method and single spot Of-digestive-tract feeds to cause spot Of-digestive-tract breeding efficiency lower for demand percentage, can not
Meet current spot Of-digestive-tract cultivation demand.
Therefore, it finds a kind of by being carried out to spot Of-digestive-tract different developmental phases (juvenile fish stage, adult fish stage and parent population stage)
Suitable cultivating condition control, and the feed that feeding is suitable, make the growth and development overall process of spot Of-digestive-tract that can obtain abundant environment
And nutritional support improves the spot Of-digestive-tract cultivation for promoting the development of spot Of-digestive-tract artificial breeding industry at fish crop to improve its trophic structure
Method is the task of top priority.
Summary of the invention
In order to solve the above technical problems existing in the prior art, the present invention provides a kind of spot Of-digestive-tract cultural method, specifically
It has the technical scheme that
A kind of spot Of-digestive-tract cultural method, comprising the following steps:
(1) fry rearing initial stage: length is selected to put into culture pond for the fry of (1 ± 0.2) cm, seedling density 250-
300 tails/m3；Feeding wheel animalcule and Copepods bait are cultivated, and feeding density is 5-10/ml；Wherein, feeding 4-5 times daily,
Each feeding weight is the 5-8% of fry weight；
(2) the fry rearing later period: when cultivation to fry length is 2-3cm, starting feeding bait, and is inflated to the water surface in micro-
Roll shape, soil pick-up, cultivates to fry length >=3cm, collects, obtains fingerling；
(3) initial stage is cultivated: according to 3000-3800 tail/m2Breeding density launch step (2) collect spot Of-digestive-tract fingerling carry out
Cultivation is fed after dispensing with initial stage spot Of-digestive-tract cultivation material, 3-6 times daily, cultivation to average body length >=20cm, the initial stage spot
Of-digestive-tract cultivation material is made of the raw material of following parts by weight: 16-24 parts of insect albumen powder, 8-12 parts of fish meal, 4-8 parts of corn flour, shrimp
5-9 parts of skin powder, 0.1-0.8 parts of lysine, 0.3-0.6 parts of methionine, 0.3-0.6 parts of cystine；
(4) it cultivates mid-term: being fed with mid-term spot Of-digestive-tract cultivation material, 2-4 times daily, cultivation to average body length >=40cm,
The mid-term spot Of-digestive-tract cultivation material is made of the raw material of following parts by weight: 30-36 parts of insect albumen powder, 12-16 parts of fish meal, corn
8-16 parts of powder, 11-15 parts of shrimp powder, 3-8 parts of chitin, 0.8-1 parts of methionine, 0.8-1 parts of cystine.
(5) it cultivates the later period: being fed with later period spot Of-digestive-tract cultivation material, 2-4 times daily, cultivation to average weight >=1kg, so
After catch, later period spot Of-digestive-tract cultivation material is made of the raw material of following parts by weight: 12-22 parts of insect albumen powder, fish meal 36-44
Part, 16-20 parts of corn flour, 8-10 parts of shrimp powder, 1-4 parts of chitin, 1-2 parts of methionine, 1-2 parts of cystine.
Preferably, the Copepods is to mix Copepods bait and the yeast extract of its weight 1.3%-1.8%.
Copepods is the palatable bait of fry, and yeast extract can improve the feeding of fish, and strengthen immunity promotes to digest and assimilate, maintains enteron aisle
Health.
Preferably, the step (1), is also inflated and soil pick-up, soil pick-up amount are the one third of water.Further preferably
, the inflation is every 0.3-1m in aquaculture pond2One No. 100 air stone is set, is used to be oxygenated for spot Of-digestive-tract aquaculture pond, gas
The speed of afrodite inflation is 1400-1500ml/min.In conjunction with air stone and miniflow water oxygenation, the molten of abundance can be provided for fry
Oxygen, and prevent oxygenation excessive, underwater bubble is excessive, and spot Of-digestive-tract fry can be made to suffer from bubble illness.
Preferably, the step (1), (2) fry rearing during to the dissolved oxygen of water in aquaculture pond, ammonia nitrogen, pH,
Water temperature is monitored, control dissolved oxygen amount be >=7.5mg/L, ammonia-nitrogen content be≤0.35mg/L, pH 7.1-7.7, salinity 0,
Temperature is 26-29 DEG C.This condition is more suitble to the cultivation of spot Of-digestive-tract fry, and the speed of growth of spot Of-digestive-tract fry is very fast at this time, disease rate
It is relatively low.
Preferably, the step (3), (4), (5) breeding process in the dissolved oxygen of water in aquaculture pond, ammonia nitrogen, pH,
Water temperature is monitored, and controls dissolved oxygen >=5mg/L, ammonia nitrogen≤0.45mg/L, pH7.2-7.6,22-28 DEG C of water temperature.This condition compared with
For the growth for being suitble to spot Of-digestive-tract, the speed of growth of spot Of-digestive-tract is very fast at this time, and disease rate is relatively low.
Preferably, the bait, the bait plants of food organisms, 25-35% containing 35-55%, 20-30% dried small shrimp
Powder.
Preferably, the insect albumen powder, one of yellow meal worm powder, earthworm powder, termite powder, fly maggot powder, blood maggot powder
Or it is a variety of.Yellow meal worm powder, earthworm powder, termite powder, fly maggot powder, blood maggot powder are good insect protein feeds.
Preferably, the insect albumen powder is to mix earthworm powder, termite powder, fly maggot powder according to following parts by weight
After obtain: 6-8 parts of earthworm powder, 14-16 parts of termite powder, 10-12 parts of fly maggot powder.The nutrition in insect albumen powder under this proportion is taken
With the growth for being more suitble to spot Of-digestive-tract.
Compared with prior art, the technical effect of the invention is embodied in:
Method of the invention cultivates spot Of-digestive-tract at times, by the breeding process of spot Of-digestive-tract be divided into fry rearing early period,
The fry rearing later period cultivates 5 periods such as early period, cultivation mid-term, cultivation later period, and each period in strict control breeding process
Water body parameter and using each period it is corresponding do not have to cultivation material fed, obtain the growth and development overall process of spot Of-digestive-tract can
To abundant environment and nutritional support, to improve its trophic structure, improve into fish crop, and the method according to the invention cultivation
Spot Of-digestive-tract, more preferably, the present invention is a kind of spot Of-digestive-tract cultural method of development that can promote spot Of-digestive-tract artificial breeding industry to meat.
