Abstract
The invention discloses a kind of cultural method of crab, pass through the primary condition and ecological environment of reasonable construction crab cultivation, select natural animal and plant feed collocation, the nutritional need reasonable disposition bait of different phase is grown according to crab, nutrition needed for crab growth is fully ensured so that survival rate, the yield and quality of crab are all significantly increased.
Description
Technical field
The present invention relates to mariculture field, and in particular to a kind of cultural method of crab.
Background technology
Crab is a kind of limnobios, has higher nutritive value, rich in abundant protein and trace element, crab
Though body it is small, the five internal organs are various, deep to be welcome by broad masses as the cuisines on dining table.But the crab grown naturally
Crab much can not meet the eating requirements of people, therefore rely on artificial breeding just to fill up gaps in market.
The key technology of crab cultivation is the side such as the foundation of aquaculture pond, feeding management, water quality management, anti-escape, anti-harmful animal
Face.The cultivation of crab needs good technology, such as growth environment, the requirement to food, water quality, water temperature and daily management side
Face.Cultivate bait that crab needs in different stage it is different, it is necessary to growing environment it is also different, many poultry feeders are cultivating
Ignore the scientific offering of crab cultivation ecological environment during crab, using industrial fits feed, cause the destruction of crab ecological environment,
Cause crab survival rate low, quality decline.
The content of the invention
The present invention selects natural animal and vegetalitas by the primary condition and ecological environment of reasonable construction crab cultivation
Feed arrangement, there is provided a kind of survival rate for effectively improving crab and yield and the cultural method of natural environmental-protective.
The present invention is realized by following steps：
(1) the good pool pollution-free, bottom of pond is smooth of water quality is selected, area is 2~3 mu, and depth is 1~1.5m, cultivation
Pool surrounding installation, which is put, escapes device；
(2) water in pool is allowed to dry, removes the excessive mud in pool bottom, stay the mud of 8~10cm depths, then disappear
Poison is handled, and or so two weeks is placed under natural conditions；
(3) water filling into pool, the depth of water are controlled in 30~40cm, are oxygenated using aerator into pond, then in water
Water plant is planted in the pool；
(4) juvenile crab is put into the pool, injected volume is 500~800 per acre, and first juvenile crab is put into pool in launch process
Immersion 2~3 minutes, further takes out and puts back to bank 5~10 minutes, 3~5 times repeatedly；
(5) observed in breeding process and adjust cultivating condition, to control pool coolant-temperature gage be 10~30 DEG C, dissolved oxygen content 6
~10mg/L, and the water of half is changed weekly；
(6) periodically feed bait sooner or later daily, each injected volume is the 5% of crab weight, and remove the plant in the pool or
Animality enemy.
It is anti-escape network, anti-escape film or put is escaped plate to be inserted into culture pond surrounding to be less than that putting in step (1) of the present invention, which escapes device,
Ground 55cm, and it is laid with securing plate in bottom.
Disinfecting in step (2) of the present invention carries out full pool spilling head using quick lime, and dosage is 80 kilograms per acre.
Water plant in step (3) of the present invention is one in hydrilla verticillata, duckweed, hornwort, eel grass, waterweed, water peanut
Kind is a variety of.
Bait in step (6) of the present invention according to the different phase that crab grows be divided into juvenile crab bait, early stage young crab bait,
Young crab bait, into crab bait, wherein juvenile crab bait be Micro Algae, artemia, duckweed press 1:3:1 ratio is mixed, early stage children
Crab bait is cyclops, water earthworm, water hyacinth, soybean residue, wheat bran press 1:1:1:2:0.5 ratio is mixed, young crab bait
3 are pressed for fishes and shrimps slurry, duckweed, corn, wheat, peanut cake:0.5:1:1:2 ratio is mixed, and is fish meal, soya-bean cake into crab bait
Powder, corn flour, multi-vitamins, sesbania powder press 2:1:1:0.1:0.2 ratio is mixed.
The present invention grows the nutritional need reasonable disposition bait of different phase according to crab, has fully ensured that crab grows institute
Need nutrition so that survival rate, the yield and quality of crab are all significantly increased.
