Description

A kind of novel artificial snakeheaded fish lay eggs case and laying nest
Technical field
The utility model relates to a kind of novel artificial snakeheaded fish lay eggs case and laying nest, belongs to aquaculture field.
Background technology
Snakeheaded fish Channa argus (Cantoor) is the economic fish of Perciformes, murrel section, Ophiocephalus.Because of snakeheaded fish fine and tender taste, nutritious, and have myogenic and enrich blood, convergence, promote the effect of wound healing, it is a kind of high-class healthy food of high protein and low fat, is the delicious food that is subjected to domestic and international consumer deeply and is liked.
The present snakeheaded fish method of laying eggs mainly contains: (1) Tu Chi method of laying eggs, generally adopt 100-200m 2The Tu Chi of size will have depth two parts at the bottom of the pond, depths 1m, and about the shallow 0.3m of place, dykes and dams build up with earth, plant water lettuce etc. in the pond, and it is right to throw in the parent population 50-100 of laying eggs, and lays eggs to water lettuce.The advantage of this method of laying eggs is that to build the pond cost low, egg laying amount is big, shortcoming is the weeds place that snakeheaded fish may produce ovum at pool side, also may bite the pasture and water that lay eggs into pieces, causes laying nest to destroy, waste parent population resource, in addition, the staff will repeatedly patrol the pond every day, and workload is huge, in case find to lay eggs, will in time fish for, fertilized egg will be moved in the incubator, if untimely, hatch prelarva, (Xu Zaikuan, the nuisanceless breed emphasis of snakehead, difficult point and example, scientific and technical literature publishing house are easy to be eaten by other snakeheaded fish, in July, 2005, the 67-68 page or leaf); (2) hatching cylinder and the little cement pit method of laying eggs, depth of water 0.4-0.8m, each container of laying eggs is only put a pair of parent population, and fishing net or fence on the container upper cover of laying eggs, jump out with shading and when preventing that snakehead from oestrusing, cause this group reproductive failure, this method advantage of laying eggs is a flexible operation, is suitable for family workshop type and lays eggs, and shortcoming is to be difficult to form bigger egg laying amount, just need to prepare dozens or even hundreds of hatching cylinder or little cement pit if lay eggs in a large number, management difficulty big (Xu Zaikuan, the nuisanceless breed emphasis of snakehead, difficult point and example, scientific and technical literature publishing house, in July, 2005, the 75-79 page or leaf); (3) Chinese patent: (Zou Jixing; Zhuo Xiaolei; Speak out the peak; Lin Yonghe, application number 200910040169.9, the breeding of hybridized snakehead fish and cultural method) a kind of breeding and cultural method of hybridized snakehead fish disclosed; (4) Chinese patent: it relates to marine culture and stock enhancement equipment (aquaculture is with artificial octopus nest for Cai Houcai, application number 200720303223.0), and particularly a kind of aquaculture is with artificial octopus nest; (5) Chinese patent: (Xing Kezhi; Cai Zhonghua; Chen Chengxun; Guo Yongjun; Liu Maochun; Ma Jingfu, application number 200420029298.0, Hatching fish net) it relates to a kind of Hatching fish net.Hatching fish-egg layer structure arranged, and its Hatching fish net outside is a frame structure, is stratum reticulare shape structure in the framework.The long 40-120cm of Hatching fish net lateral frame, wide 30-100cm.Framework Intranet layer structure is the polythene net sheet.(6) Chinese patent: (Ling Qufei, application number 200810108046.X, the fish nest that a kind of artificial propagation loach is used) the fish nest that a kind of artificial propagation loach is used is disclosed, comprise open-topped net cage and palmae bark, described net cage is a double-decker, be fixed with the separate mesh of 10~15 millimeters of meshes between the levels, be provided with at the middle part of described separate mesh upper surface and induce fish nest, described palmae bark to be laid on described inducing on the fish nest; (7) Chinese patent: (Tang Zuopeng; Zhang Guoqiang, application number 01138822.6, large-scale artificial breeding technology for yellow cartfish) it relates to large-scale artificial breeding technology for yellow cartfish, and the fish nest is set: put into a rectangle wall with 6 bricks in the bottom, pond, at two ovum frames of wall inner bottom part lay, mutual group adult fish nest; The related method of these patents all has advantage separately, but owing to be not at the design that snakeheaded fish lays eggs and the scale breeding is done, so they are not suitable for the breeding physiology characteristic of snakeheaded fish.
Therefore, need searching a kind of easy to operate, be suitable for the instrument of snakeheaded fish scale breeding.
The novel artificial snakeheaded fish lay eggs case and laying nest be a kind of method easy, save work, the workable snakeheaded fish device of laying eggs, and, it is little to have the snakeheaded fish damage, hatching can be operated in the case of laying eggs, characteristics such as breeding quantity is big, cost is low, therefore, its exploitation uses the breeding as China snakeheaded fish that new approach is provided.
Summary of the invention
The utility model mainly is at the existing in prior technology problem, and a kind of novel artificial snakeheaded fish lay eggs case and laying nest are provided.Be suitable for snakeheaded fish scale breeding, damage little, prelarva survival rate height; In addition, can hatch in conjunction with net cage, operation is simple, with low cost.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of novel artificial snakeheaded fish lay eggs case and laying nest is characterized in that: comprise that lay eggs case, snakeheaded fish laying nest and fixed part of snakeheaded fish form.
(1) the snakeheaded fish case of laying eggs: do not have tubercle net sheet by polyethylene and make long 2.0m, wide 3.0m, high 1.2m rectangle net cage is provided with dead lever around the upper opening, net cage, net cage is provided with upper and lower opening guiding principle rope, and with net cage upper and lower opening guiding principle rope bolt jail on dead lever, the mesh size of net cage is in 9 orders.
(2) snakeheaded fish laying nest: make circular configuration with iron wire, diameter is 1.0m, bondage live body water peanut on iron wire, and in the gap of water peanut bondage willow fibrous root, circular void is left in the centre of laying nest, water peanut 1g/m 3Bleaching powder sterilization back use, use after the willow fibrous root need be placed on and be exposed to the sun under the sunlight three days, be put into snakeheaded fish after laying nest is carried out immediately and lay eggs in the net cage, and be fixed on the dead lever around the net cage with rope.
As preferably, net cage does not have tubercle net sheet with polyethylene to be made, and like this, also is not easy scratch during snakeheaded fish breeding ovulation fertilization aggravating activities.
As preferably, the mesh size of net cage is in 9 orders, and bigger mesh can make things convenient for the exchange of the inside and outside water body of net cage, and the prelarva after the breeding also can be swum out of net cage easily, comes among the Da Chi and cultivates.
As preferably, circular void is left in the centre of snakeheaded fish laying nest, can guarantee snakeheaded fish the carrying out smoothly of activity that lay eggs, and increases the ovulation space.
As preferably, bondage willow fibrous root in the gap of snakeheaded fish laying nest water peanut, because of the willow coring can be used as the important carrier that fertilized egg is adhered to, snakeheaded fish is in the process of laying eggs, because adding, violent activity bites the live body water peanut into pieces, the deficiency that may cause water plants to adhere to nest, but its not fragile willow fibrous root, therefore, it can be used as its important replenishing.
