Abstract
The invention discloses a healthy breeding method of Chinese sturgeons. The healthy breeding method comprises the following specific steps: supplying water with clear water quality (with the transparency of more than 600cm) and sufficient dissolved oxygen (more than 6mg/l) for 1-12 days-old larva fish after birth, but no feeing; feeding the larva fish 12 days later in juvenile fish period, wherein tubificidae can be taken as main fodder, and water flea and fairy shrimp are taken as auxiliary fodder; feeding aquatic oligochaeta when the larva fish grows greater than 6cm in young fish period; feeding adult fish fodder when the larva fish grows grater than 30cm in adult fish period. Through the manner, the healthy breeding method of Chinese sturgeons provided by the invention adopts different fodder proportions at different periods according to high requirement of the Chinese sturgeons on protein, so that the Chinese sturgeons can be grown healthily in a pollution-free manner.
Description
Technical field
The present invention relates to aquaculture field, relate in particular to a kind of healthy aquaculture method of mandarin sturgeon.
Background technology
Mandarin sturgeon is a kind ofly in the Changjiang river, to breed, the large magical fish that grow up in the sea, and it has been survived nearly 100,014,000 years on earth, is one of the most ancient existing vertebrate, can be rated as " living fossil in water ".The individuality of mandarin sturgeon is very large, and body is brave and fierce, becomes fish length can reach 5 meters, and body weight reaches very heavy, and the life-span reaches at the age of one hundred years old, occupies the hat of the 27 kinds of sturgeons in the world, is the fish of individual maximum, longest-lived in freshwater fish.
Mandarin sturgeon has own exclusive life habit.All viable migration fishes of typical salt water, fresh water.Male mandarin sturgeon grows into more than 9 years old, long 1.7 meters of body, and body weight is more than 50 kilograms, and female mandarin sturgeon grows into more than 14 years old, and long 2.3 meters of body, more than body weight 120 kg, reaches first sexual maturity, just can bear children.In the annual autumn in summer, the mandarin sturgeon gathering in groups band together, by living in neritic zone outside entrance of Changjiang River the Changjiang river of migrating to, is gone through rich the hitting of the stream that traces back of more than 3000 kilometer, just gets back to " native place " Jinsha jiang River one of oneself and is with egg reproduction.Postpartum, treat that juvenile fish grows up to 15cm left and right, these " aliens " carry again sons and daughters, go downstream, and reside overseas.
Yet the quantity of mandarin sturgeon is rare, how keeps these " living fossils in water " and become the extremely urgent problem of brainstrust.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of healthy aquaculture method of mandarin sturgeon, the healthy aquaculture method of this mandarin sturgeon requires to have taked the different forage compounding of different times to the harshness of protein according to mandarin sturgeon, makes it can healthy free of contamination growth.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the healthy aquaculture method of mandarin sturgeon, and concrete steps comprise:
1) prelarva being just born 1-12 days do not need feeding, but need to keep water quality limpid (more than transparency 600cm) and sufficient dissolved oxygen (more than 6mg/l);
2) after 12 days, prelarva enters the postlarva phase, and feed can be take water earthworm as master, water flea and fairy shrimp are as auxiliary;
3) the postlarva phase throws initial two days that raise, throw something and feed every day 2 times, be respectively sooner or later respectively once, it is the 10%-20% of fry gross weight that day is thrown the amount of raising, water flea and fairy shrimp can be added 1 every day, and the postlarva phase is thrown rising to the postlarva of total length 6cm for the 3rd day of raising, and every day, the number of times of throwing something and feeding of water earthworm rose to 3-4 time, day, feeding volume was the 20%-30% of fish body weight, and water flea and fairy shrimp can be added 1-2 time every day;
4) postlarva grows to and while being greater than 6cm, enters young stage, when the appropriate to the occasion aquatic oligochaetes of throwing something and feeding of juvenile fish total length 5-15cm, as tubificid, water silk earthworm and cercobranchiate earthworm etc., when juvenile fish total length 15cm is above, can add and feed shrimp and fairy shrimp etc., the bait throwing in time is with comparatively suitable before and after 8 o'clock every days, 14 o'clock, 18 o'clock, 24 o'clock;
5) juvenile fish grows to while being greater than 30cm and enters the adult fish phase, can feed its adult feedstuff.
In a preferred embodiment of the present invention, the proportioning of described adult feedstuff is by weight percentage: fish meal 55%, AP301 hyperglobulinemia 8%, fish oil 3.5%, a-starch 5%, corn flour 5%, wheat flour 15%, brewer's yeast 5%, choline (50%) 0.5%, B B-complex 1%, complex inorganic salt catalyst 2%.
The invention has the beneficial effects as follows: the healthy aquaculture method of a kind of mandarin sturgeon of the present invention, the healthy aquaculture method of this mandarin sturgeon requires to have taked the different forage compounding of different times to the harshness of protein according to mandarin sturgeon, makes it can healthy free of contamination growth.
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: the healthy aquaculture method of mandarin sturgeon, and concrete steps comprise:
