Description
Technical field
The utility model belongs to Fishing tool technical field, particularly relates to a kind of fry harvesting purse seine device.
Background technology
In fish hatching is produced, seed harvesting and the general purse seine that adopts of screening carry out drawing in the net operation, and fry often slips away from fishing net edge and bottom; Especially in grouper seedling raising process, because grouper is in the seed phase, dorsal fin and pectoral fin fin spine are hard thorn, and it is outstanding open-shaped, in the process of drawing in the net, fry is often too concentrated, thus causes mutually extruding to cause stabbing, injured fry very easily falls ill when harvesting and transport, finally causes nursery failure.Traditional approach needs to drive piles at the bottom of the pool in advance to enclose an interim net cage before results, then by drawing in the net fry to catch up with into interim net cage, wastes time and energy.Therefore be badly in need of one at present can effectively prevent escaping, avoiding fry injured, improve the purse seine device of fry harvesting efficiency.
Utility model content
For the problems referred to above, the utility model provides a kind of fry harvesting purse seine device, to solve problems of the prior art.
Technical solutions of the utility model are as follows:
A kind of fry harvesting purse seine device, it is characterized in that, described purse seine device comprises fishing net and floating net cage, and described fishing net is provided with wing, and described fishing net is communicated in described floating net cage by described wing.
Preferably, described wing is provided with a clasp, and opening described clasp can separate described fishing net and described floating net cage.
Preferably, described fishing net comprises etting, headline and ground rope, described headline is suspended with ball float, described ground rope is hung with plummet, described headline is positioned at described fishing net upper end-face edge, described ground rope is positioned at described fishing net lower edge, is connected with etting between described headline and described ground rope.
Preferably, described wing is connected to described fishing net centre, described wing both ends open and described both ends open has a shaping ring respectively.
Preferably, described wing flare, it is large that described wing connects described fishing net one end open, connects described floating net cage one end open little.
Preferably, described floating net cage is square structure, and described floating net cage end face surrounding has been provided with floating frame.
Preferably, described floating net cage size specification is 1.5m × 1.5m × 1.0m.
The beneficial effects of the utility model are: be connected with floating net cage by fishing net by wing, and fry is just difficult to escape after entering floating net cage by wing, also can effectively avoid fry to extrude injured; Clasp simultaneously due to wing being set up, tightens cuff between floating net cage and clasp, takes clasp and separable fishing net and floating net cage apart and carry out gathering in the crops or sieving seedling, without the need to making interim net cage in addition; The fishing net of floating net cage of dismantling also can connect other floating net cage and again draw in the net fishing operation; Use the utility model purse seine to carry out the operation of fry harvesting, convenience and high-efficiency, can labour intensity be reduced, save working time.
Accompanying drawing explanation
Fig. 1 is the utility model using state vertical view.
Embodiment
For the ease of the understanding of those skilled in the art, be described further technical solutions of the utility model below in conjunction with embodiment and accompanying drawing, the content that embodiment is mentioned is not to restriction of the present utility model.
With reference to Fig. 1, a kind of fry harvesting purse seine device, purse seine device comprises fishing net 1 (comprising 4,5 and 6) and floating net cage 2, and fishing net is provided with wing 3, and fishing net 1 is communicated in floating net cage 2 by wing 3; Wing 3 centre position is provided with a clasp 10, and opening clasp 10 can separate fishing net 1 and described floating net cage 2; Fishing net 1 comprises etting 4, headline 5 and ground rope 6, headline 5 is suspended with ball float 7, ground rope 6 is hung with plummet 8, and headline 5 is positioned at fishing net 1 upper end-face edge, and ground rope 6 is positioned at fishing net 5 lower edge, is connected with etting 4 between headline 5 and ground rope 6; Wing 3 is connected to fishing net 1 centre, wing 3 both ends open and both ends open has respectively a shaping ring 9, facilitates fry to enter; Wing 3 flare, it is large that it connects fishing net 1 one end open, connects floating net cage 2 one end open little; Floating net cage 2 is square structure, and floating net cage end face surrounding is provided with floating frame 11; Floating net cage size specification is 1.5m × 1.5m × 1.0m.
The fry harvesting purse seine fishing process of the utility model embodiment is as follows: after fishing net 1 drawout of the present embodiment, under in nursery pond, the clasp 10 buckled in the middle part of wing 3 connects fishing net 1 and floating net cage 2, the pull rope 12 that operator pulls fishing net 1 advances, finally receiving net catches up with into floating net cage 2 by fry in fishing net 1 by wing 3, tighten the wing 3 of contiguous floating net cage 2 end, untie clasp 10, namely fry gathers in the crops in floating net cage 2, move floating net cage 2 to bank, can screen and packing and transporting fry; As operation again need be drawn in the net, fishing net 1 can be connected other floating net cage 2, repeat aforesaid operations.
Be more than better embodiment of the present utility model, but embodiment is not for limiting the utility model, not departing from the spirit and scope of the utility model, any equivalence change done or retouching, belong to the protection domain of the utility model equally; Therefore the content that protection domain of the present utility model should define with the claim of the application is standard.
