Abstract
The invention discloses a breeding method of crabs. The breeding method of crabs comprises the followings steps of (1) selection of a pool, wherein a pool made of clay or sandy oil and with good ventilation performance is selected; (2) preparation of food organisms, wherein aquatic plants are planted in the pool, and the aquatic plants are one or more types of duckweeds, azoila imbricate, water hyacinth, water lettuce, hydrilla varticillata or alternanthera philoxeroides; (3) offspring seed distribution, wherein purchased offspring seeds are firstly soaked in water for 2-3 minutes, then taken out for 20 minutes of standing, and finally put into the pool after young crabs gradually absorb water and adapt to the water temperature; (4) bait feeding, wherein 40% of baits are fed from March to June, and 60% of baits are fed from July to October; and (5) regular disease treatment, wherein calcium oxide is mixed with water and sprayed to the whole pool to achieve 15PPM. The breeding method of crabs has the advantages of improving the survival rate that zoeas are changed into megalopas, being high in offspring seed growth rate, being tidy in growth, and being high in offspring seed survival rate.
Description
Technical field
The present invention relates to aquaculture technical field, specifically the cultural method of a kind of crab.
Background technology
Crab (p á ngxie): the animal kingdom, Arthropoda, Crustachia, Decapoda, Reptantia.Crab is shellfish (crustacean), and their health is being protected by duricrust.Crab is by gill respiration.In biosystematics, crab and shrimp, lobster, hermit crab be similar animal at last.The crab of most kinds lives in the sea or near ocean, also has the crab of some dwell in fresh water or stay in land.They are by female crab little crab in next life, and each female crab all can produce a lot of ovum, more than quantity can reach millions of grains.Crab is to rely on earth's magnetic field to judge direction.
Summary of the invention
The cultural method that the object of this invention is to provide a kind of crab.
Technical scheme of the present invention is achieved in that 1) pond selects: select clay or sandy soil, air capacity of soils Hao pond; 2) preparation of food organisms: plant pasture and water in pond again, described pasture and water are one or more in duckweed, Azolla imbricata, weter hyacinth, water lettuce, hydrilla verticillata or water peanut; 3) put seedling: the seed of buying back is first soaked 2-3 minutes in water, take out into putting 20 minutes, after young crab progressively suctions moisture and adapts to water temperature, drop in pond; 4) bait throwing in: divide 40%, 7-October 60% 3-June; 5) regularly except sick: be watered full pool spilling head with quicklime and be 15PPM.
Beneficial effect of the present invention is: it is the survival rate of megalops larva that the cultural method of crab of the present invention improves zoea metamorphosis, and seed fast growth is grown neatly, plants shoot survival percent and reaches height.
Embodiment
The cultural method of a kind of crab: 1) pond is selected: select clay or sandy soil, air capacity of soils Hao pond; 2) preparation of food organisms: plant pasture and water in pond again, described pasture and water are one or more in duckweed, Azolla imbricata, weter hyacinth, water lettuce, hydrilla verticillata or water peanut; 3) put seedling: the seed of buying back is first soaked 2-3 minutes in water, take out into putting 20 minutes, after young crab progressively suctions moisture and adapts to water temperature, drop in pond; 4) bait throwing in: divide 40%, 7-October 60% 3-June; 5) regularly except sick: be watered full pool spilling head with quicklime and be 15PPM.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; according to technical scheme of the present invention and inventive concept thereof, be equal to replacement or changed, within all should being encompassed in protection scope of the present invention.
