Abstract
The invention discloses an eel reproduction net cage and an eel reproduction method. The eel reproduction net cage comprises a cage body. The eel reproduction net cage is characterized in that meshes are formed in the cage body, the cage body is filled with soil, aquatic plants are planted in the soil, a support is arranged in the cage body, the support is composed of longitudinal rods which are arranged in sequence, the longitudinal rods are fixed through cross rods respectively, the aquatic plants are planted, the support is placed, the soil is loosened in time, a plastic sheet is arranged on the periphery of the cage body, the surface of the plastic sheet is smooth, and the plastic sheet is used for preventing lobsters and crabs in a pond from crawling into the cage body. The eel reproduction method comprises the steps that the reproduction net cage containing eels is placed in the pond in April, an opening of the net cage is higher than the water surface of the pond, eel fries are attached to the loose soil and the aquatic plants and grow, the reproduction net cage is moved out of the pond in June, incubation and reproduction of the eel fries are completed between April and June, and companion culturing of aquatic products such as the lobsters and the crabs can be conduced all year round at the same time. By the adoption of the reproduction net cage and the eel reproduction method, space utilization and time utilization of the breeding pond are maximized, and the aquatic products such as the lobsters and the crabs are attached to the aquatic plants to grow, and the aquatic plants can improve the water quality.
Description
Technical field
The invention belongs to cultivation fishery field, particularly relate to a kind of yellow eel hatching breeding net cage and propagation method.
Background technology
Eel cultivation has formed larger industry in aquaculture fishery field at present, the cultivation general little Chi of employing in fishing ground breeds yellow eel, each little pool side has a rule ridge, ridge takies larger vacant lot, but because breeding pond is less, water is more shallow, the more difficult control of water quality, breeding yellow eel is higher to the requirement of breeding water body, when little Chi water quality is poor, it is more difficult changing tank water.
The hatching breeding of existing yellow eel is all to breed by net cage, the net cage that breeding yellow eel seedling is housed is placed in pond, in net cage, carry out the breeding of nothing soil, eel fry hatching breeding whole structure is not good, and hatching reproductive output is lower, then on this basis, carries out having soil to breed in net cage, breeding yellow eel seedling is placed on the interior soil of net cage, only have soil breeding net cage more single, in net cage, soil knot is with regard to unfavorable yellow eel hatching breeding growth, and yellow eel breeding hatching survival rate is lower.
According to characteristic and the time of yellow eel hatching breeding, improve the reproductive survival rate of yellow eel, need good water quality to be beneficial to eel cultivation, consider to improve little pool cultivated be pond culture, yellow eel hatching repoductive time is 4 annual-June, if pond culture only for yellow eel breeding closely at three months, larger waste the room and time of cultivating pool.Thus, utilize usage space and the time in pond, improve and breed pond water quality, improve yellow eel reproductive survival rate, making yellow eel breed pool cultivated utilization maximization is also to need at present the problem of solution.
Summary of the invention
Object of the present invention is just to provide a kind of yellow eel breeding net cage and propagation method, by plantation pasture and water and placing rack, loosens the soil in time, improves yellow eel hatching reproductive survival rate, is conducive to yellow eel seedling and enters the large batch of cultivation in pond, improves output, increases the benefit.
Another object of the present invention is just to provide a kind of yellow eel propagation method, little Chi breeding is improved to the breeding of large pond, adopt the yellow eel hatching breeding of large pond to overlap aquatic products such as supporting lobster, crab simultaneously, make cultivating pool space and time utilization realize maximize utility, and plant pasture and water and be beneficial to cultivation lobster, crab and can improve water quality again.
Technical scheme of the present invention: a kind of yellow eel breeding net cage, comprise casing, be mainly on casing, to be provided with mesh, in casing, be filled with soil, in soil, plant and have pasture and water, in casing, be provided with support, described support is ordered arrangement vertical pole, and vertical pole is fixed by cross bar respectively, and the outer surrounding of casing is provided with Polypropylence Sheet.
A propagation method, its step is as follows:
1) prepare: yellow eel breeding little Chi, cut out each ridge of little pool side, Jiang little Chi is modified into large pond, in large pond plantation pasture and water, in net cage, be filled with soil, in soil, plant and have pasture and water, in casing, be provided with support, the external surrounding of net cage is provided with Polypropylence Sheet, and yellow eel seedling is put into net cage;
2) cultivation: at aquatic products such as the annual cultivation in large pond lobster, crabs, put into pond by the breeding net cage that yellow eel is housed April, net cage mouth is higher than the pond water surface, promotion support loosens the soil, yellow eel seedling adheres to loosen the soil grows with pasture and water, and the breeding of yellow eel seedling survived and grew up June, yellow eel is bred to net cage and shift out pond, from casing, pull yellow eel seedling out to bringing up the pool, the 4-6 month in large pond, complete yellow eel hatching breeding and overlap aquatic products such as supporting lobster, crab simultaneously;
3) water purifies: the aquatic products such as lobster, crab adhere to pasture and water growth, and pasture and water are improved water quality.
The present invention compared with prior art also has advantages of:
1, yellow eel breeding net cage of the present invention, casing is provided with mesh, puts into the net cage in pond, water enters by mesh, making has water in case, the outer surrounding of casing is provided with Polypropylence Sheet, can prevent that the aquatic products such as shrimp in pond, crab from climbing into casing because plastics cloth cover is comparatively smooth.
2, yellow eel of the present invention breeding net cage can be filled with soil according to the characteristic of the yellow eel of hatching breeding in casing, in soil, plants and has pasture and water, and yellow eel seedling can hygrometric water root growth, and pasture and water can improve water quality, is beneficial to yellow eel hatching breeding environment.
3, yellow eel breeding net cage of the present invention, adopt in casing and be provided with support, support is by the fixing vertical pole of ordered arrangement of cross bar, prop up and be placed in soil, with hand, slightly promote rack cross-bar, can drive vertical pole to rotate in soil is slight, reach the effect of loosening the soil, the yellow eel seedling that is beneficial to hatching breeding is grown in more loose soil.
4, the method for yellow eel breeding of the present invention, is modified into large pond by yellow eel breeding from little Chi breeding, takes full advantage of ridge vacant lot, and in pond, plant pasture and water, purification of water quality is beneficial to hatching breeding yellow eel and survives and grow, and breeds yellow eel in pond between April to June, and annual time cover is supported the aquatic products such as lobster, crab, improve cultivation availability, thereby cut the waste, the other plantation of yellow eel net cage successively high, eat the pasture and water such as unbeaten, not only can improve water quality, and can cultivate lobster, make maximizing the benefits.
Accompanying drawing explanation
