Abstract
The invention discloses a sturgeon feeding method, belongs to an aquatic product breeding method, and aims to provide the sturgeon feeding method which is high in survival rate and rapid in growth. The method comprises fry stocking: subjecting fries to disinfection and water temperature adaptability processing before stocking, and then, placing the fries into a fishpond simulating the aquatic environment according to a certain density; feeding: feeding the fries everyday according to timing, regular and quantitative principles; and daily management: performing daily management and disease control according to life habits of sturgeons. According to the sturgeon feeding method, the simulated aquatic environment accordant with natural life habits of sturgeons, a scientific feeding method and a daily management method are adopted, so that effects of whether and human activities on sturgeons in the natural environment are avoided effectively, the survival rate and the growth rate of the sturgeons are improved, and the method is a commercialized sturgeon feeding method.
Description
Technical field
The present invention relates to a kind of aquaculture method, relate in particular to a kind of method of raising sturgeon.
Background technology
Sturgeon is the famous-particular-excellent treasure of China, have the title of " panda in the water " and " living fossil in the water ".Have high edible, medicinal, view and admire and economic worth.Sturgeon is other parts (containing bone) edible all except the body surface hone lamella, and nutritive value is high, is listed in high tonic.Sturgeon promotes brain development to softening cardiovascular and cerebrovascular, improves IQ, and the prevention senile dementia has favorable effects; Cartilage and marrow (being commonly called as " rail ") contain the anticancer factor, and saying of " shark fin, sturgeon bone " arranged; Therefore sturgeon has high medical value again.In addition, sturgeon is the cartilage ganoid, belongs to the fish in time immemorial, and the title of living fossil is arranged; Because its form uniqueness, sights a kind of deep and serene, simple and unsophisticated, unique sensation arranged, so in areas such as Southeast Asia, Hong Kong, Macao and Taiwan it is considered as first-class pet fish.Sturgeon also has higher economic value, and the sturgeon skin is the good raw material of making high-grade leather and fur products, and tear resistance, wearability, pliability can match in excellence or beauty with crocodile skin.
Yet owing to reasons such as environmental pollution and overfishings, the sturgeon ecotope has suffered heavy damage, causes some sturgeon kind endangered.In order to save these endangered species, number of research projects has been done in aspect such as countries in the world are bred sturgeon, released, breed.At present, though sturgeon cultivation plays certain success, survival rate is low, growth is slow, still can not meet the need of market.
Summary of the invention
At the above-mentioned defective that exists in the prior art, the present invention aims to provide a kind of method of raising sturgeon, and this method can overcome the defective that present artificial feeding sturgeon survival rate is low, growth is slow.
To achieve these goals, the present invention by the following technical solutions: it comprises fry put in a suitable place to breed, throw something and feed feed and daily management; Its method is as follows:
1) fry is put in a suitable place to breed, with fry put into be equipped with concentration be the plastic sack of 2~3% salt solution sterilize 10~15 minutes will; Then the above-mentioned plastic sack that fry is housed being immersed flow velocity is 0.1m
3/ s, water temperature be 19~23 ℃, transparency greater than 30 ㎝, oxygen dissolved greater than 5 ㎎/L, ammonium ion less than 0.0125 ㎎/L, pH value be 7.5~8.5, nitrite is less than the Chi Shuizhong of 0.2 ㎎/L, treats that water temperature and the pond water temperature in the plastic sack approaches the back by hybridization sturgeon 100~300 tails/m
2, amur sturgeon 30~50 tails/m
2Density fry is put into pool wall for being the fishpond of pan bottom shape at the bottom of oval, the pond;
2) feed of throwing something and feeding, dawn every day or period at the dusk feed of throwing something and feeding in the following manner in the fixed position: fry weight is less than 50g, and 5 time, day feeding volumes of throwing something and feeding every day are 10% of fry weight; Fry weight is at 50~200g, and 4 time, day feeding volumes of throwing something and feeding every day are 6% of fry weight; Fry weight is greater than 200g, throw something and feed every day 4 times, every day feeding volume be 4% of fry weight; The time of throwing something and feeding is 40~60 minutes at every turn, feeding volume is 25% of day feeding volume at every turn;
3) daily management, blowdown and cleaning fishpond are 2~3 times weekly, and each quantity of wastewater effluent is 1/2 of Chi Shui; Should reduce discharge when throwing something and feeding feed at every turn, close oxygen increasing pump, recover again after 30 minutes; Throw something and feed at every turn and answered blowdown 5 minutes and reduced water level before the feed; The sturgeon of Different Weight should be carried out the branch pond in per two months and raise, tackle before the branchs pond that the pond body carries out disinfection, sterilization treatment.
Compared with the prior art, the present invention has taked to disinfect with salt solution and the water temperature adaptive processes when fry is put in a suitable place to breed owing to adopted technique scheme, therefore can improve the survival rate of seedling; Owing to changed the fishpond wall into ellipsoidal structure, therefore not only be conducive to Chi Shui and flowed, but also can avoid the fish body easily by the defective of pool wall scratch.In addition, owing to adopted the simulation aquatic environment that meets sturgeon self-sow habit, the feeding method that has adopted science and daily management method, therefore avoid sturgeon in natural environment, to be subjected to the influence of weather and mankind's activity easily effectively, improved sturgeon survival rate and growth rate.
Embodiment:The invention will be further described below in conjunction with specific embodiment:
1) fry is put in a suitable place to breed, with fry put into be equipped with concentration be the plastic sack of 2~3% salt solution sterilize 10~15 minutes will; Then the above-mentioned plastic sack that fry is housed being immersed flow velocity is 0.1m
3/ s, water temperature be 19~23 ℃, transparency greater than 30 ㎝, oxygen dissolved greater than 5 ㎎/L, ammonium ion less than 0.0125 ㎎/L, pH value be 7.5~8.5, nitrite is less than the Chi Shuizhong of 0.2 ㎎/L, treats that water temperature and the pond water temperature in the plastic sack approaches the back by hybridization sturgeon 100~300 tails/m
2, amur sturgeon 30~50 tails/m
2Density fry is put into pool wall for being the fishpond of pan bottom shape at the bottom of oval, the pond;
2) feed of throwing something and feeding, because sturgeon is feared high light, fry goes into Chi Houying at dawn every day or period at the dusk feed of throwing something and feeding in the following manner in the fixed position: fry weight is less than 50g, and 5 time, day feeding volumes of throwing something and feeding every day are 10% of fry weight; Fry weight is at 50~200g, and 4 time, day feeding volumes of throwing something and feeding every day are 6% of fry weight; Fry weight is greater than 200g, throw something and feed every day 4 times, every day feeding volume be 4% of fry weight; The time of throwing something and feeding is 40~60 minutes at every turn, feeding volume is 25% of day feeding volume at every turn;
3) daily management needs blowdown weekly and cleans the fishpond 2~3 times, and each quantity of wastewater effluent is 1/2 of Chi Shui; Should reduce discharge when throwing something and feeding feed at every turn, close oxygen increasing pump, recover again after 30 minutes; Throw something and feed at every turn answer blowdown before the feed 5 minutes, water level is reduced; Every raising should be carried out the sturgeon of Different Individual weight the branch pond in two months and raises, and tackled at every turn that the pond body carries out disinfection, sterilization treatment in branch the pond before.
In the above-described embodiments, when the fry in the step 1) was the hybridization sturgeon, fry breeding density was 100~300 tails/m
2When fry is amur sturgeon, fry breeding density is 30~50 tails/m
