Description
Technical field
The present invention relates to marine fishery fishes for apparatus technical field, and in particular to a kind of receipts of Wild Rhubarb fish live body germplasm
Collection netting gear.
Background technology
Large yellow croaker, also known as yellow croaker, cucumber, yellow croaker, were once one of China's famous " four Large Marine Ecosystem economic fish ", its product
Amount is only second to hairtail and pelagic fishes.It is distributed to the Lezhou Peninsula at the South Sea on the south the Shandong Peninsula of China's Huanghai Sea.
Since the sixties in 20th century, because artificial catching intensity is excessive and the reproductive growth environment of the spawning of suitable large yellow croaker and forage meets with
It was once that the large yellow croaker of one of four big fishing seasons has faced the condition of extinction to heavy damage.At present, 3 wild species of large yellow croaker
Group also has fragmentary distribution in each sea area, but its market price is 20-30 times of cultured population price, therefore large yellow croaker is artificial foster
Grow and seem increasingly important.The key that large yellow croaker is propagated artificially is to set up large yellow croaker live body Germplasm Bank, and storing in Germplasm Bank has numerous
The alternative parent of difference proterties is the key link of large yellow croaker industry healthy and sustainable development.Wild Rhubarb fish is due to its proterties
The features such as variation is big, available degree is strong, genetic diversity is abundant, is the primary source of Germplasm Bank live body parent.Due to wild
Large yellow croaker is mainly distributed on the middle lower floor marine site of 30-60m isobaths, and because of scarcity of resources, is difficult to collect with conventional method
Live body Wild Rhubarb fish.Along with large yellow croaker anti-stress ability is weaker, easily dead from water, that is, allow to fish for and by its therefrom under
Layer life marine site is promoted to topmost surface, and because the mutation of hydraulic pressure causes its internal pressure to increase suddenly air bladder spalling or stomach are made
It is dead outside capsule is exported from Esophageal Pressure, therefore a great problem for being collected into the sector of Wild Rhubarb fish live body germplasm.Therefore,
A kind of collection netting gear dedicated for Wild Rhubarb fish live body germplasm of exploitation is extremely urgent.
The content of the invention
It is an object of the invention to provide a kind of collection netting gear of Wild Rhubarb fish live body germplasm, overcomes and lacks in the market
The weary collection netting gear dedicated for Wild Rhubarb fish live body germplasm, the defect for causing its live body germplasm collection difficult, there is provided a kind of
Simple structure, low cost, fish for that accuracy is high, be greatly improved live body germplasm collection survival rate dedicated for Wild Rhubarb fish
The collection netting gear of live body germplasm.
The collection netting gear of the Wild Rhubarb fish live body germplasm that the present invention is provided, it is described to fish for net including net and hawser is fished for
Dredger two ends end to end are connected to by two first hawsers, the sieve bottom of fishing for is provided with a Minitype underground video camera, institute
The camera lens top for stating Minitype underground video camera is provided with a red eye that can constantly flash, and the Minitype underground video camera connects
The LED display being connected on dredger；The mesh for fishing for net taper off from top to bottom formula diminution, fish for sieve bottom and be provided with one
Individual slip-knot outlet, the slip-knot outlet surrounding bolt plummet, fishes for net and fishes for net including epimere nylon wire and hypomere plastic cement cloth,
The nylon wire and plastic cement cloth are fished for Netcom and cross fixed cover connection, and the lower end of the nylon wire and plastic cement cloth fish for the equal ring of net
It is placed on fixed cover, the fixed cover is the annulus of stretchable its diameter of control, the stretching end of the fixed cover is by the
Two hawsers are connected with dredger.
Used as preferred, the dredger is connected by the 3rd hawser with cargo ship, and cargo ship is equipped with running water oxygenation keep-alive
Facility, in time can be transported the live body Wild Rhubarb fish fished for bank by cargo ship.
The using method of the collection netting gear of the Wild Rhubarb fish live body germplasm, comprises the following steps：
（1）Put net：The slip-knot for fishing for sieve bottom is exported and is tightened up, the length of first hawser at fore tail two ends of controlling fishing
Degree, elongates the second hawser, makes to fish for net and sinks in the sea water layer with Wild Rhubarb fish, fishes for online fixed cover in diameter
Maximum rating；
（2）Fish for：Start Minitype underground video camera, red eye and LED display, Minitype underground video camera is by water body
In situation be sent to LED display, when Wild Rhubarb fish enter fish for net nylon wire when, red eye constantly flashes suction
Draw Wild Rhubarb fish to plastic cement cloth fish for network game move, when Wild Rhubarb fish into plastic cement cloth fish for net after, tense the second cable
Rope, it is 0 that the diameter of fixed cover is drawn；
（3）Receive net：Pull the first hawser to carry out receipts net, fish for net and often raise 5m 10 ~ 20min of pause.
In the art tool has the advantage that the present invention：（1）The cooperation that the present invention passes through the second hawser of pulling and fixed cover
Half part off the net can be fished for freedom retractable, and notice that ought fish for net often raises 5m 10 ~ 20min of pause when net is received, to allow
Wild Rhubarb fish progressively adapts to the pressure of the water level, prevents visceral rupture, the phenomena of mortality from occurring such that it is able to for Wild Rhubarb fish
The foundation of live body germplasm provides the Wild Rhubarb fish of high-quality；（2）Can be timely by water-bed situation by Minitype underground video camera
The LED display being sent on dredger, so as to more accurately be fished；（3）That what is designed fishes for off the net section of plastic cement cloth
Because its quality is soft, Wild Rhubarb fish can be protected in network process is received, and keep certain moisture to subtract after netting gear surfaces
The harm such as few large yellow croaker stress beat, scale comes off, scratch, further increase the collection survival rate of its live body germplasm.
