A kind of cultural method of ecological fish, it is to prepare plant source feed with bean dregs, fishbone dust, yeast fermentation with the one or more in the discarded edible mushroom after crushing, using the earthworm of waste edible fungus chaff for breeding as animal sources feed, the one or more in grass carp, silver carp, variegated carp, carp, crucian are raised with this, and feed quantity is added by control in breeding process, refreshed the water periodically, the quality of the periodically measure such as sterilization and Air Exposure raising fish.
Description
Technical field
The invention belongs to technical field of aquaculture, and in particular to a kind of cultural method of ecological fish.
Background technology
With the rapid rising of fishery industry, increasing people begins to focus on freshwater aquiculture.Common pond since most
The pool cultivates, a variety of breeding way such as industrialized fish pond till now, family's courtyard pool, rivers and canals reservoir, and yield is not yet
It is disconnected to rise.According to data, China's Fish-water Fish Farming yield in 2015 is up to 30,000,000 tons.But China's cultured freshwater fish
Veriety is single, and the major class yield of grass carp, silver carp, carp, bighead, crucian, Tilapia mossambica etc. six accounts for China and cultivated fresh water fishes total output
78%.Kind it is single, not only cause fish market dog-eat-dog, cultivation profit falls sharply.Especially with social development, people
To the demand of fish from quantity to mass shift.If the fresh-water fishes price that the preferable large reservoir of water quality cultivates is apparently higher than general
The garden cultivation of long and deep friendship between two families front yard, and supply falls short of demand.Therefore, following development of fresh water fishery is the quality for how improving fish.
The content of the invention
It is an object of the invention to provide a kind of method for breeding of ecological fish, and in particular to a kind of ecology rich in amino acid
The cultural method of fish.
The purpose of the present invention is realized by following technical measures：
A kind of cultural method of ecological fish, specifically includes following steps：
（1）Pond desilting, shine the pool and disinfect；
（2）Select one kind in grass carp, silver carp, variegated carp, carp and young crucian similar in physical strong, disease-free and injury-free, size
Or several launched；400~500 tails of grass carp/mu, fish weigh 0.2~0.3kg/ tails, 100~150 tails of silver carp/mu, fish during dispensing
Weighing 0.1~0.2kg/ tails, 20~30 tails of variegated carp/mu, fish weigh 0.1~0.2kg/ tails, and 50~100 tails of carp/mu, fish weigh 0.05~
0.1kg/ tails, 800~1000 tails of crucian/mu, fish weigh 0.05~0.1kg/ tails；It is to fit to launch one of which or 2~3 kinds of fries
Degree increase fry mantissa；
（3）Feed intake 2 times daily, 8 a.m. and at dusk 6 points of each throwings are once；Feed is divided into plant source feed and animal sources feed, throws
Plant source feed and animal sources feed are alternately launched when putting feed；Plant source feed dosage is the 10%~15% of fish body weight, is moved
Material resource feed dosage is the 5%~10% of fish body weight, and winter injected volume halves；
（4）To ensure the quality of fish, it is necessary to ensure that pond quality of water, therefore require that pond is refreshed the water periodically（Refresh the water periodically the time
For 1~2 month）, or using flowing water culture；
（5）Pond is periodically carried out disinfection processing using lime water, quick lime dosage is every square metre of 10~20 grams of water surface, is disappeared
Full pool spilling head 1~2 time after quick lime is dissolved with water when malicious；Periodically sterilization can change water with pond and be combined, and lime water is noted
Enter in changed water；
（6）Further to improve pond waters quality, so as to improve grass carp quality, periodically it is aerated 1~2 hour daily.
The feed launched for reduction, which remains in, destroys Water quality in water, so as to influence the quality of fish, the throwing of the feed
Put place to fix, and the food-residue for remaining in water bottom was periodically removed every 15 days.
Plant source feed is the mixed fodder prepared using the fermentation such as discarded edible mushroom and bean dregs, fishbone dust, and edible mushroom has
Body is mushroom, mushroom, coprinus comatus, Stropharia rugoso-annulata, straw mushroom, agaric, russule, Trichotoma matsutake（Matsutake）, it is dried mushroom, high in purple ganoderma lucidum etc.
One or more in shelves edible mushroom.
The plant source feed preparation process is as follows：
（1）The discarded edible mushroom of collection is crushed to 1~2cm of particle diameter；
（2）By the edible mushroom after crushing, bean dregs, fishbone dust, feed inorganic salts, yeast in mass ratio 40~50:30~50：10
~15：1~5：1~3 ratio mixes, and is fermented 5~6 days under the conditions of 20~30 DEG C；Mixture water content is controlled during fermentation
50%~60%；
（3）It after fermentation ends, can directly launch to fishpond, granulated meal can also be made using adhesive and launch again.
Animal sources feed is to utilize mushroom, mushroom, coprinus comatus, Stropharia rugoso-annulata, straw mushroom, agaric, russule, Trichotoma matsutake（Pine
It is fine and soft）, the earthworm raised with biogas slurry after spontaneous fermentation of dried mushroom, the medium-to-high grade edible fungi residue such as purple ganoderma lucidum.
In summary, using the technical program, it is remarkably improved the quality for raising grass carp.This is primarily due in edible mushroom
Rich in multiple nutritional components such as amino acid, protein, carbohydrate, lipid, vitamin, mineral element, nucleotides, have high protein,
Low sugar, low fat, several amino acids and the characteristics of deposit, also containing substantial amounts of protein, crude fibre, crude fat, reduction in bean dregs
The nutriments such as sugar, total reducing sugar, breeded fish, substantially can increased in grass carp using discarded edible mushroom, bean dregs and fishbone dust tunning
The nutrition contents such as amino acid, protein；And in the technical program, grass carp, silver carp, variegated carp, carp, crucian symbiosis can
The utilization ratio for launching feed is significantly improved, and is purified water using silver carp therein, variegated carp, carp, crucian.
Embodiment
The present invention is specifically described below by embodiment, it is necessary to it is pointed out here that be that following examples are only used
It is further described in the present invention, it is impossible to be interpreted as limiting the scope of the invention, person skilled in art can
So that some nonessential modifications and adaptations are made to the present invention according to foregoing invention content.
