Abstract
The utility model provides a lamp light trapping device of larval fishes. The lamp light trapping device of the larval fishes solves the problem that due to the fact that fry can be hurt by a fry distributing device of fishes in the prior art easily, the fry survival rate is reduced. The lamp light trapping device of the larval fishes comprises a hollow container (1) used for containing the larval fishes and a light source (3). An opening is formed in the upper portion of the container. A bottom board is arranged on the lower portion of the container. The lamp light trapping device of the larval fishes further comprises a bottom frame (2). The light source is fixed on the bottom frame. A seat ring used for placing the bottom board of the container is arranged on the bottom frame. The position of the light-emitting end of the light source is higher than the seat ring. A hole corresponding to the light-emitting end of the light source is formed in the bottom board of the container and the hole is larger than the light-emitting end. A cover board (4) enabling the hole to be opened and closed is hinged to the portion, at one side of the hole, of the bottom board. The cover board is led to the upper opening of the container through an operating rope (8). A pulling handle (5) is arranged on the upper portion of the container. The lamp light trapping device of the larval fishes has the advantages of being simple in structure, low in cost, small in fry damage rate and high in survival rate and fry distributing rate.
Description
Technical field
The utility model belongs to the cultural technique field, relates to the lamp light trapping device of a kind of trapping device, particularly a kind of young postlarva.
Background technology
In the fish hatching process,, along with growing up of fry, usually need reduction to cultivate density and divide pond, method commonly used is to lure collection with light at present, then with the string bag or bucket, fishes for.Due to the young postlarva stage fry scale not yet grow, if misoperation is very easily damaged fry, thereby reduce the survival rate grow seedlings.And, utilize the string bag to fish for efficiency higher, but easily damage is grown seedlings; Fish for not easy damaged fry with bucket, but efficiency is too low.
, owing to there being this problem,, through retrieval, find that there is Chinese patent literature and disclose a kind of lamplight drop net [patent No.: ZL 201110217910.1 that is provided with minute fish device and silver carp bighead seedling safe escape channel; Granted publication number: CN102349478A].This lamplight drop net that is provided with minute fish device and silver carp bighead seedling safe escape channel, comprise fishing net, the fishing net string bag and light supply apparatus, is provided with one deck fry separate mesh sheet in fishing net inside, and the mesh of described fry separate mesh sheet is greater than the mesh of described fishing net; Described fry separate mesh sheet center is provided with closed the second outlet; Be provided with the 3rd outlet at described fishing net near bottom position; Be provided with the passway for escaping that is surrounded by the net sheet between described fishing net bottom and described fry separate mesh sheet, described the second outlet of the upper port docking of described passway for escaping, described the 3rd outlet of the lower port docking of described passway for escaping.First by the fry safe escape channel, silver carp bighead seedling is freeed when lamplight drop net is fished, then silver carp grown bighead carp and the classification of reservoir small fishes are captured in the light net string bag.Utilizing the lamp light trapping fish to lift net carries out the seizure of finished product fish and reservoir small fishes and silver carp bighead seedling is not damaged.
But there is complex structure in this lamplight drop net, and therefore the high in cost of production shortcoming, invents a kind of practicality, and is efficient, and easy lures acquisition means for improving fry minute pond efficiency, reduces the fry damage probability and extremely is necessary.
