Description

The fresh-water fishes breeding and catching net case

The utility model relates to a kind of fresh-water fishes breeding and catching net case, belongs to a kind of instrument of feeding the fishing class.

The breeding and catching net case of existing fresh-water fishes, unreasonable structure, the one, be netted at the bottom of the fish box, put into the fish food of net cage, meet the fish food of pigmentization especially, at the bottom of net cage, drain to the case external water area greatly, cause the waste of fish food, do not have the purpose of feeding fishing; The 2nd, before and after the exit of fish food interstation guiding net do not have closed door, make the fish that enters in the front eating table also can swim back rear eating table and enter the case external water area, the fishing output minimizing.

It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and the fish food does not spill net cage, the fresh-water fishes breeding and catching net case that fishing is many.

The purpose of this utility model reaches by the following technical programs.This fresh-water fishes breeding and catching net case comprises the receipts fishnet, front eating table, rear eating table, forward and backward guiding net, the anti-net of escaping, at the bottom of framework and the netted case, its special character is, laid a substrate again at the bottom of the netted case, and a valve is established in the exit of front guiding net between front eating table, rear eating table, receive the horn-like little net of establishing two opening in the fishnet, the big mouth of this little net is connected as a single entity with receiving the fishnet inlet, fish can only be found enter the inlet of receiving fishnet, can not find the outlet of running away from the receipts fishnet.Substrate at the bottom of the netted case can be a Polypropylence Sheet, nylon cloth, diablement fort etc.The net bottom that the utility model is received fishnet can be made of net and the metal frame (ring) of fixedlying connected with it; Also can and be fixedly connected on its bob all around by net constitutes.Back guiding net and receipts fishnet can be one, also can be two.If guide net after one, a receipts fishnet, it is bigger then to receive fishnet, and retractable is not too convenient.

A kind of embodiment preferably of the utility model is, described back guiding net, receive fishnet and be two, and the guiding net is horn-like that its osculum is connected as a single entity with the inlet of receiving fishnet.It is less to receive fishnet like this, and retractable is convenient.

The utility model another preferably embodiment be, the net bottom of described receipts fishnet, by net and with net around want that the net that connects weighs down and constitute.Receipts fishnet retractable with this net bottom is convenient, has guaranteed that promptly net bottom fully opens, and is beneficial to entering of fish, again can be laborsaving when hauling.Convenient in order to receive net, also can on four angles of receiving the fishnet network interface, respectively establish a cleek, hang over by this cleek on the framework of net cage.

Because the utility model has adopted above-mentioned technical solution, it is had do not waste the fish food, when receiving fish, fish enters in the rear eating table can not go to waters outside the net cage, and fishing is many, receives net characteristics easily.This net cage is fixed on the dark about 3 meters place of reservoir, feeds fish in this domestication throughout the year and make them get used to regularly eating food, after domestication after a while at this, fish just can enter in groups and look for food, close valve, make them enter the receipts fishnet, reach the purpose of fishing for by rear eating table.This catching method, economy, convenient.This net cage promptly can be used for artificial intensive culture waters, throws in the domestication of fry feeding, makes fish from little just food when this net cage is decided at the higher level but not officially announced, to catching season, valve can be closed, and they are caught.Also can be used for unartificial intensive culture waters, in this net cage, tame fish, through after the domestication it being caught after a while with fish meal.

Provide embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying the utility model.
