Abstract

The invention relates to fish catching equipment. The equipment comprises a net cage, wherein stabilizing piles (2) are respectively arranged at the four corners of the net cage to serve as supports; three diagonal drawing ropes (1) are tied in the upper middle parts of the stabilizing piles to be used for stabilization; the lower parts of the diagonal drawing ropes are fixed at the water bottom along with ground piles (9); fixed pulleys (5) are arranged on the stabilizing piles; one end of each of lifting ropes (6) is tied on a floatage frame (4) and the other end of each of the lifting ropes is gathered by the fixed pulleys through turning and then is connected with a pulling rope (7); the pulling rope is finally tied on a windlass (11) to be convenient to stretch; an electrified (10) insulated wire is connected on the upper parts of the stabilizing piles which are diagonal to each other; a 400w lamp (3) with a shade is added in the position above the middle part of the opening surface of the net cage, of the insulated wire to attract insects; and a net cage peripheral netting (8) is arranged on the underwater part of the net cage. The equipment has the following advantages: the fish fries grow fast; the caught fish bodies are free from injury; the input is less; the manpower is saved; and the equipment is beneficial to agricultural production.

Description

A kind of device for use in fishing trawl

Technical field

The present invention relates to a kind ofly both can breed fish, again the equipment that can fish.

Technical background

Fishing is the long-term work taken up of numerous fishermen, and in fish production, Fishing tool is particularly important.Instruments such as the hook of Shi Yonging, bamboo weir, net, card are along with development of times in the past, and be difficult to suitable or backward relatively, because the extensive use of new science and technology new material, ultrasonic fishing device, electrical network, electricity have occurred and Fishing tool such as dragged, though production efficiency has improved, they have very big destruction to fishery resources.I have createed a kind of both time and labour saving by the long-term observation and research, do not influence the device for use in fishing trawl of fishery resources again.

Summary of the invention

Purpose of the present invention is exactly to utilize the phototaxis of insect, and to the specific bodies of water, fish sees the characteristics that insect falls over each other to prey on insect attractant, and a kind of device for use in fishing trawl that provides.

In order to realize that purpose of the present invention adopts following technical scheme:

A kind of device for use in fishing trawl, it is characterized in that it comprises a net cage, be provided with 4 anchor spikes (2) outside the turning of net cage, three oblique ropes (1) lie in the anchor spike middle and upper part, the oblique rope bottom is connected with pile (9), the anchor spike bottom is provided with 4 fixed pulleys (5), halliard (6) is connected in buoyancy framework (4) and passes through fixed pulley downwards, gather after turning to pull rope (7) and be connected, 2 anchor spike tops are provided with insulated electric conductor (10) and connect power supply, insulated electric conductor is positioned at top, net cage actinal surface middle part and is provided with 1 400w Capped electric lamp (3), and pull rope is connected on the winch (11).The net cage underwater portion is a net cage external network sheet (8).

For the ease of using, the actinal surface of net cage with square for well, rectangle also can, the actinal surface length of side of net cage is in 8-25 rice, the underwater portion of net cage is advisable with dark 1.5-2 rice.The spacing of anchor spike and net cage should be in 0.5-2 rice scope, and the 400w Capped electric lamp should be in 1-3 rice scope apart from water surface elevation, and pile should be lower than water-bed ground.In use apart from pull rope every halliard far away as being suspended on the net cage, can also will add two fixed pulleys apart from the near anchor spike of pull rope, make apart from pull rope every halliard far away through two fixed pulleys, thereby can not be suspended to net cage.The fixed pulley of anchor spike bottom should be installed on the centre position on net cage bottom and water-bed ground.The width of mesh of net cage external network sheet is according to circumstances decided, with 1 * 1 centimetre-3 * 3 centimetres.

Effect benefit fruit: 1, pull winch at dusk, pulling traction rope sinks under water net cage, and the winch spanner fixed, open the 400w Capped electric lamp night, because the phototaxis of insect, can assemble a lot of insects at the light place, the insect that has falls into water accidentally, fish assemble a large amount of fish because there has been a large amount of insects to fall over each other to go and episite to light place travel for predation under light, when the shoal of fish gathers certain amount, the winch spanner is loosening, and net cage emerges under the buoyancy of buoyancy framework automatically, and the shoal of fish also just is loaded into net cage.

2, the buoyancy framework of net cage being connected in anchor spike with rope makes it stable.Put into fry in the net cage, open the 400w Capped electric lamp night, insect becomes light to the gathering of light place, and the part insect falls into water and just in time preyed on by fry, and behind the long-term episite feed of fry, its growing way is higher than the fry that eats plant feed far away.

Advantage of the present invention: 1, fishing is fished the time and labour saving with this equipment, and cost is little, and the fish body of being caught does not have hurt, and is fresh and alive, the commodity value height, and the small fish of being caught can also be from newly putting in a suitable place to breed.

2, breed fish, the fry episite is the carnivority feed, and it is than plant feed nutrition height, thereby promotes long fast of fry, and less investment is in addition saved artificial.

3, breed fish with the fishing of this equipment and can reduce number of pest, thereby reduce crop pests, useful agricultural production.

Embodiment

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of device for use in fishing trawl provided by the invention, it is characterized in that it comprises a net cage, around net cage, do an anchor spike (2) respectively as supporting with four turnings of net cage, three oblique ropes (1) are lain in the anchor spike middle and upper part be used to stablize, the oblique rope bottom is fixed on the bottom with pile (9).Also have fixed pulley (5) on anchor spike, an end of halliard (6) ties up on the buoyancy framework (4), and the other end passes through fixed pulley, gathers after turning to pull rope (7) to be connected, and pull rope ties up at last to be convenient on the winch (11) stretch.Two become the anchor spike top at diagonal angle to connect the insulated electric conductor (10) of switching on therein, add 1 400w Capped electric lamp (3) at insulated electric conductor by the place above the net cage actinal surface middle part, are used for attracting insect.The net cage underwater portion is a net cage external network sheet (8).For the ease of using, the actinal surface of net cage is used square more, rectangle also can, the actinal surface length of side of net cage is in 8-25 rice, the underwater portion of net cage is advisable with dark 1.5-2 rice.The spacing of anchor spike and net cage should be in 0.5-2 meter scope, and the 400w Capped electric lamp should be in 1-3 rice scope apart from water surface elevation, and pile should be lower than water-bed ground.In use apart from pull rope two halliards far away as being suspended on the net cage, can also will add two fixed pulleys apart from the near anchor spike of pull rope, make apart from pull rope every halliard far away through two fixed pulleys, thereby can not be suspended to net cage.The fixed pulley of anchor spike bottom should be installed on the centre position on net cage bottom and water-bed ground.The size of the mesh of net cage external network sheet is according to circumstances decided, as suitable 2 * 2 centimetres of spring, and suitable 3 * 3 centimetres of summer, suitable 1 * 1 centimetre of winter.Annotate: this equipment fishes that catch are the fish of water body at the middle and upper levels more.In the above-mentioned material, buoyancy framework, anchor spike are made of mao bamboon, and pile is with 16 reinforcing bar, and oblique rope, halliard, pull rope all use plastic ties.
