Abstract
The invention discloses a pearl mussel breeding method. The pearl mussel breeding method includes steps of 1) breeding in a pond which is 2-2.5 meters in depth, 6.5-8 in pH (potential of hydrogen) value and 4-8mg/l in dissolved oxygen; 2) fertilizing the pond in 3-5 days before pearl mussels are placed into the pond; 3) breeding non-carnivorous fishes such as grass carps, breams, bighead carps and crucians in the pond; 4) drilling small holes on the shells of the pearl mussels so as to string the pearl mussels by ropes; 5) feeding proper food organisms, applying rare-earth nutrient sources once in the peak period of growth of the pearl mussels so that the concentration of the pond is 0.1mg/l; 6) subjecting all pregnant mussels to pregnancy examination in three to four months before collecting the pearl mussels, and classifying according to fetal development. The pearl mussel breeding method adopts mixed breeding technology, and the bred pearl mussels are bright in pearl luster, high in yield and low in cost.
Description
Technical field
The present invention relates to aquaculture field, relate in particular to a kind of nacreous cultural method.
Background technology
Pearl freshwater mussel claims again pearl oyster pearl freshwater mussel, is commonly called as clam.Because of its voluminous natural peral pearl freshwater mussel of gaining the name, pearl shell is large, thick and solid, is oblong, shell length can reach 180mm, the high 70mm of shell, the wide 40mm of shell, two shells expand, shell face dark brown, or nearly black, and be furnished with the spot with gloss, move in river and brook, in China, be mainly distributed in the province such as Heilungkiang, Jilin, in the part section in Dalian, also have the distribution of some, also there is distribution Japan and the former Soviet Union area all brings out fresh water pearl.
Hokkaido, Japan once had pearl freshwater mussel artificial culture pearl successfully to report, and pearl matter is good, exactly like the natural sea-water pearl that the Persian Gulf produces, and pearl freshwater mussel is not yet applied to pearl production at present in China, this is a kind of novel pearl culturing clam resource that awaits exploitation.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of nacreous cultural method.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of nacreous cultural method, and concrete steps comprise:
1) select 2 ~ 2.5 meters of the depth of waters, the pH value of water is 6.5～8, and the pond of dissolved oxygen amount 4 ~ 8mg/l cultivates, and pond area is according to circumstances determined, and size is 5 ~ 50 mu;
2) pearl freshwater mussel is put into pond and apply fertilizer to pond for first 3 ~ 5 days, make to keep in water body Ca
2+ content is more than 15 mg/litre, also with elements such as magnesium, silicon, manganese, iron;
3) in pond, raise together with the non-predacious fishes such as grass carp, bream, flathead, crucian, breeding density is 50～100 tail/mus again;
4) on pearl shell, beat an aperture, stringed together with restricting, carry out hanging culture according to female-male proportion 1:1,50 centimetres of left and right of spacing between male and female, put 300 ~ 400 in a suitable place to breed for every mu;
5) feed its suitable food organisms, monthly apply rare earth nutrient source once in the pearl freshwater mussel growth busy season, make Chi Shui be the concentration of 0.1mg/l;
6) 3 ~ 4 months before collecting seedling every year, the female freshwater mussel of all becoming pregnant is cooked to the inspection of once becoming pregnant, carry out classification processing according to mold development degree, mold is grown and is substantially completed, and maturity more than 80% is divided into the first order, and mold is grown general, maturity more than 70% is divided into the second level, it is poor that mold is grown, and maturity is divided into the third level lower than 60%, and cultivate at different positions, waters according to the different rank cultivation of becoming pregnant.
In a preferred embodiment of the present invention, the food organisms in described step (5) comprise the organic debrises such as diatom, chrysophyceae, green alga, Euglena, microzooplankton and bacterium.
In a preferred embodiment of the present invention, the rare earth nutrient source in described step (5) is nitric acid type.
The invention has the beneficial effects as follows: a kind of nacreous cultural method of the present invention adopts mixed culturing technology, the pearl color and luster that cultivation pearl freshwater mussel out produces becomes clear, output is high, and cost is low.
Embodiment
Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
The embodiment of the present invention comprises: a kind of nacreous cultural method, and concrete steps comprise:
