Abstract

The invention provides a method for fishing artificially cultured copepods in a seawater pond, which includes: making a wingless trap net, which is 3.0m in opening width, 0.6m in height, 8.0m in body length and 80 in mesh number, and a cod-end 4.0m in length and 150 in mesh number; tying the whole opening of the net to a square frame which is made of plastic pipes 3cm in diameter and in 3.0m (upper edge and lower edge)X0.6m (left edge and right edge); driving two stakes 3m away from each other in the center of the pond; tying the square frame for the opening of the trap net to the two stakes; installing a 1.5kw double-wheeled waterwheel type aerator 4.0m away from the front of the opening; starting the aerator to generate water flow in the pond, which flows to the trap net, so that the copepods in the water are filtered in the cod-end of the trap net; operating the aerator for 2-4 hours every day so as to fish pure live copepods weighing about 5-15kg. The method is simple in process, can be operated by one person, and is laborsaving, timesaving and low-cost. Residual copepods, residual fertilizer, residual water and residual foundation feed in the pond can be fully used, and continuous cultivation and fishing of the copepods are guaranteed.

Description

Adopt the method for catching artificial culture copepoda in the sea pond

Technical field

The present invention relates to the aquatic product fishery technical field, particularly adopt the method for catching artificial culture copepoda in the sea pond.

Background technology

Adopt to throw the net in natural marine site and to catch copepoda and lean on trend, and do not have trend in the cultivating pool; In the pond, adopted in the past and catch copepoda and use light to lure collection, manual work to fish for, or drive trawlnet and drag and get with motor-driven canoe, these operations are loaded down with trivial details, will many people operate, the effort of taking a lot of work, and cost is also high; Taking of having opened a sluice gate and drawn out some water, thrown the net at the gate mouth and fish for, and this method can all be arranged light originally can be used for expanding numerous residual copepoda, rich water and foundation bait in the pond, not only wasted resource but also has been unfavorable for that continuous culture catches with adopting.

Summary of the invention

In order to overcome the above-mentioned weak point that exists in the prior art, the object of the present invention is to provide a kind of method of catching artificial culture copepoda in the sea pond of adopting.

In order to reach above-mentioned purpose, the present invention adopts following concrete technical scheme: adopt the method for catching artificial culture copepoda in the sea pond, it is characterized in that following steps:

(1) making of throwing the net: make wide 3.0 meters, the high 0.6m of network interface, the long 8.0m of body, mesh is 80 orders; The long 4.0m of net capsule, mesh is that 150 purposes do not have the chord net, and body is sewed with one section 70cm length, mesh 40 purpose rubbish filter screens with net capsule junction, and whole network interface is bundled on 3.0m (going up following) * 0.6m (right sides) square frame of processing with the plastic tube of diameter 3cm.

(2) laying of throwing the net: parallelly in the center in pond lay two and be longer than the dark timber in pond or bamboo stake, galvanized pipe; Two pilespacings are from 3m; Be bundled in two the 0.6m right sides of network interface of throwing the net respectively on two piles together with plastic tube, and carry out up-down adjustment during fluctuation in stage, make the top just expose the about 10cm of the pond water surface in the pond; Network interface is facing to the prevailing wind direction in pond.

(3) aerator configuration set: the two-wheel waterwheel aerator of a 1.5kw is installed at about 4.0m place in the network interface dead ahead; Hole, 4 vertical gardens on the oxygenation unit floating platform; Each is fixed at the bottom of the pond with steel pipe or round timber piles, and the oxygenation unit is gone up and down with the up-down of water level;

(4) operation of throwing the net: start aerator and in the pond, form and flow to the current of throwing the net, the copepoda in the water and the young thereof are filtered in the net capsule of throwing the net, and the 2～4h that starts shooting approximately every day can adopt the pure live body copepoda that catches the about 5～15kg of weight in wet base.

Compared with prior art, the present invention has following outstanding advantage and effect: this method operation is simple, single can operate, save labor, cost is low; Can also make full use of residual copepoda, rich water and foundation bait in the pond, guarantee its continuous culture and adopt to catch.

Embodiment

A kind of method of catching artificial culture copepoda in the sea pond of adopting is characterized in that following steps:

(1) making of throwing the net: make wide 3.0 meters, the high 0.6m of network interface, the long 8.0m of body, mesh is 80 orders; The long 4.0m of net capsule, mesh is that 150 purposes do not have the chord net, body is sewed with one section 70cm length, mesh 40 purpose rubbish filter screens with net capsule junction.Whole network interface is bundled on 3.0m (going up following) * 0.6m (right sides) square frame of processing with the plastic tube of diameter 3cm.

Operation of the present invention is simple, single can operate, save labor, cost is low; Can also make full use of residual copepoda, rich water and foundation bait in the pond, guarantee its continuous culture and adopt to catch.

Claims

1. adopt the method for catching copepoda in the sea pond for one kind, it is characterized in that following steps:

(1) making of throwing the net: make the wide 3.0m of network interface, high 0.6m, the long 8.0m of body, mesh are 80 orders, net the long 4.0m of capsule, mesh is that 150 purposes do not have the chord net; Be sewed with one section 70cm length, mesh 40 purpose rubbish filter screens in body and the net capsule junction; Whole network interface is bundled on 3.0m (going up following) * 0.6m (right sides) square frame of processing with the plastic tube of diameter 3cm;

(2) laying of throwing the net: parallel two timbers that can expose peak level or bamboo stake, the galvanized pipe of laying in the center in pond; Two pilespacings are from 3m; Be bundled in the right sides of two 0.6m of network interface that throw the net respectively on two piles together with plastic tube, and carry out up-down adjustment during fluctuation in stage, make the top just expose the about 10cm of the pond water surface in the pond; Network interface is facing to the prevailing wind direction in pond;
