Abstract
The invention belongs to the field of animal cultivation, and particularly relates to a cultivation method for crabs. The cultivation method for the crabs is high in survival rate of the crabs, growth speed and quality of the crabs. The cultivation method for the crabs comprises the following steps that a water area with good-quality pollution-free water and with a smooth bottom of a pool is chosen, a fence is arranged around the water area, and the pool is constructed; excessive sludge on the bottom of the pool is cleaned up, then thorough disinfection is carried out, water is completely exchanged after the disinfection, a hose provided with multiple air outlets is arranged in a 5-10cm portion of the sludge, the hose is connected with an aerator, and oxygen is inflated into the pool through the aerator and the hose to protect the crabs against suffocation; water plants are planted in the pool; juvenile crabs are placed into the pool, and the breeding density is appropriately 400-500 crabs per mu; in the crab cultivation process, cultivation conditions are frequently observed and regulated; in the crab cultivation process, bait throwing is carried out twice a day in the morning and at evening; and merchandise crabs can be caught to appear on the market through crab cages in October.
Description
Technical field
The invention belongs to the animal-breeding field, especially relate to the cultural method of a kind of crab.
Background technology
Crab claims again river crab, is the fresh water crustacean, in fresh water, grow up, and crab delicious, nutritious.Crab is at present by Chinese and the overseas universally recognized cuisines of people, at present owing to still take and fish for as main in the source of crab, it is less that artificial culture work is carried out, the crab of self-sow can not meet people's eating requirements far away, although rely in recent years the cultivation of small size to supplement the needs in market, equally also do not alleviate the demand in market.
At present, the technology of propagating crab artificially is a lot of not enough after also, and people are to artificial experience of supporting crab imperfection also.The bait difference that the cultivation crab needed in the different stages, the growing environment needed is also different, a lot of technical staff ignore the science setting of crab cultivation ecotope when the cultivation crab, use industrial manufactured feed, blindly medication, cause the destruction of crab ecotope, cause the crab survival rate low, quality descends.
Summary of the invention
The present invention is exactly for the problems referred to above, provides that a kind of crab survival rate is high, the cultural method of fast growth and the high a kind of crab of crab quality.
To achieve these goals, the present invention adopts following technical scheme,
The cultural method of crab comprises the following steps:
(1) select pond; Select that water quality is well pollution-free, at the bottom of pond smooth waters, places fence, builds up pond; Fence inserts the low 60cm in pond and is advisable, and lays gusset plate in the fence bottom, prevents the crab flight;
(2) build and support the crab environment; Remove the too much mud of pond bottom, stay the mud that 12cm is dark to be advisable, then thorough disinfection, water is thoroughly changed one time in sterilization later, in mud, 5～10cm place is provided with the flexible pipe of a plurality of gas outlets, flexible pipe is connected with aerator, by aerator and flexible pipe, in pond, fills oxygen, in order to avoid crab is suffocated; Plant pasture and water in pond, pasture and water are the food of crab still not, and can purify water, and the principal item of pasture and water is eel grass, waterweed and hydrilla verticillata;
(3) juvenile crab is put into to pond, while throwing in juvenile crab, water temperature is advisable at 10～12 ℃, in launch process, first juvenile crab is put into to pond water 3～4 minutes, putting back to bank 30～35 minutes, 2 times repeatedly, allow juvenile crab adapt to water temperature, cultivation density is that every mu of 400～500 crabs are advisable;
(4) in the process of cultivation crab, often observe and regulate cultivating condition, the pond water temperature is at 10～32 ℃, and pH value is 6～8, and dissolved oxygen content is advisable at 5～9mg/L;
(5) in cultivation crab process, within every 7 days, change one time water, respectively throw in one time bait every day sooner or later, each injected volume is 4%～5% of crab body weight, and 3～April, main bait was small fish, screw, mussel meat, wheat, corn etc.; Mainly throw in 5～July such as pasture and water, Ipomoea batatas, pumpkin, potato etc.; Be the crab weightening finish stage 7～October, mainly throws in small fish, screw and granular bait for fish;
Water temperature rising in (6) 5～July, 22～23 o'clock nights of every day are opened aerator, to next day 3～5 o'clock, close;
(7) can will become crab to fish for listing by the crab cage October.
Further, throw in a collection of screw before throwing in juvenile crab in pond, screw not only can be edible for crab, also can purify water.
Further, described aquaculture water hardness is less than 350mg/L.
Again further, the depth of water in pond remains on 0.8～0.9m.
Beneficial effect of the present invention:
The present invention throws in by pond environment setting and the bait of science, makes the survival rate of crab high, and growth rate is fast.When it is hot, by aerator, be oxygenation in pond, reduced the death of crab.
