Description
Technical field
The technical field of finishing device is the utility model is related to, is caught more particularly, to a kind of natural fry of yellowfin spine porgy
Drag for device.
Background technology
Yellowfin spine porgy is also known as Sparus Latus, is under the jurisdiction of Perciformes, porgy section, spine porgy category, popular name Huang wall, and yellow pin is stood, red wing etc., extensively
It is general to be distributed in China's southeastern coast, it is common shallow sea water warm demersal fishes, its Fresh ＆ Tender in Texture, few spinelet, and it is nutritious,
Thus deep love consumers in general welcome, and are important marine products economic fish, are released as South Sea Fishery Resources Enhancement in recent years
In one of important kind.Therefore, sea-farming, enhancement releasing etc. are increasingly vigorous to the demand of yellowfin spine madai seedling.
The fishing of natural fry is with a long history in China, and appropriate artificial fishing does not interfere with its benefit to Natural Population
Fill.Although yellowfin spine porgy artificial propagation techniques are ripe, by contrast, catch natural fry and can not only reduce and be produced into
This, can also save the area shared by the auxiliary devices such as parent fish pond needed for artificial propagation, spawning pond, storage pond, holding pond；It is in addition, natural
Fry individual life power and survival rate are higher, the purification and rejuvenation to fingerling, avoid causing individual to degenerate what is diminished because of " inbreeding "
Phenomenon has certain meaning.So in actual production, it is an indispensable link to catch natural fry, and ensures fish
The survival rate of seedling is the most important point.
At present, fry fishing mainly has two methods：
（1）Method one is manual fishing, specifically in harbour, coastal shoaling, catches a kind of simple hand fork of the Miaos' held by both hands
Net device, promote hand fork net forward in water, the eyes moment watches the water surface attentively, lifts net after catching fry, fry is loaded
In fry collecting vessel with hanging over.
The subject matter of the method：Fry amount of fishing is very limited, and labour cost is high（Take time and effort）.
（2）Method two is trawl fishing, and specifically using there is wing trawlnet netting gear, towing fishing is carried out by motor-driven ship,
Net is received after certain time, fry is collected and temporarily supported.
The subject matter of the method：Though improving many than traditional manual catching rate, trawlnet makes the intensive collection of fry
In in net capsule part, easily mutually extruding, collision and cause mechanical injuries, reduce survival rate of fish fry.
In summary, a kind of natural fry finishing device of efficient yellowfin spine porgy is needed badly, preferably to utilize and protect day
Right fry resource.
The content of the invention
The utility model is to overcome at least one defect described in above-mentioned prior art, there is provided a kind of yellowfin spine porgy is natural
Fry finishing device.

In the utility model, in fishing link, the ebb principle that rises of seawater is made full use of, the sea designed is caught automatically
Dragging for natural fry device has the advantages that quantity of the catch is big, cost is low, fry survival rate is high.
Further, described fish-catching apparatus is a prismatic table shape body, and respectively there are an opening, the opening of narrower one end in its left and right
It is connected with fish-aggregating device.Above-mentioned Stability Analysis of Structures, and the effect fished is good.
Further, described fish-catching apparatus includes body, wing, wing rope, timber, and body is by upper and lower, left and right
Four ladder net blind stitchings form；It is two panels rectangle net that the wing, which includes, is distributed in the left and right sides of wider one end open；It is described
Wing rope includes wing top and bottom rope, and wing is strutted as rectangle；The timber is connected with wing rope, by timber
Insert and marine fix the device.
Further, described fish-aggregating device is a circular cylinder cage, including bottom steel ring, middle and upper part steel ring, top steel
Circle, side steel bar, bottom etting, side etting, reel rope, anchor line, sinker；
Described side steel bar connects bottom steel ring, middle and upper part steel ring, top steel ring, and the side steel bar is symmetrical,
From bottom, steel ring is continuously connected to top steel ring, is furnished with side etting thereon；Bottom etting is fixed on the steel ring of bottom, it is described to reel
Rope is continuously connected to the overthe openings of fish-catching apparatus from top steel ring, and anchor line is connected with sinker.
Further, several sinkers are uniformly fixed on described bottom steel ring, the intersection for having cross-fixing inside steel ring
Steel bar, the middle and upper part steel ring uniformly fix several floats.
Further, described anchor line one end is connected on the intersection steel bar of bottom steel ring, and the other end is connected with sinker；
The opening blind stitching for having narrower one end of an opening and fish-catching apparatus on etting between middle and upper part steel ring and bottom steel ring connects.
Compared with prior art, beneficial effect is：Not only quantity of the catch is big for the utility model, labour cost is low, and can be with
Fry survival rate is improved to greatest extent.The standardization of fishing and other natural fry resources suitable for yellowfin spine madai seedling
Investigation and stock number are assessed etc. in terms of scientific research, effectively reduce mortality in natural fishing and caused by fry resource wave
Take, be that standardized operation, stock assessment, sustainable use of natural fry resource investigation etc. provide substantial technical support.
