Embodiment Construction

[0015] a breeding pond such as figure 1 Shown, construct mud smear district 9 on three sides with embankment, reserve a rectangular pond in the middle, a short side of rectangle is open. The middle of the pond is vertically separated by a dividing wall again, and only at one end of the short side surrounded by the mud-smeared area is an isolation fence-4, which separates the left and right sides of the pond. The left and right sides are respectively separated from the front and back by the horizontal separation fence 2 6 and the water diversion dam 2 . A water-air mixing device is installed in the water diversion dam. The side of the water diversion dam facing the open short side has a water inlet, and the other side is provided with an array of water-air mixture spray outlets. From the diversion dam, according to the ejection direction, it is the main breeding unit 3 first, and it is the omnivorous fish unit 5 that turns after the separation fence one, and then the pond filt...

Abstract

The invention provides a large-density seawater culture device which is a seawater pond.A main culture unit (3), an omnivore fish unit (5), a pond filter feeding shellfish unit (7), a mud flat filter feeding shellfish unit in a mud flat area (9) and a kelp unit (10) are distributed in the pond in the seawater flow direction.A water and gas mixing device is installed at a water inlet of the main culture unit, and a water inlet of the kelp unit is connected with a mud flat water outlet.Compared with the prior art, various organisms are combined to co-exist in one seawater system, plankton is freely propagated in the system, feed residues, excrement and nutrients such as dissolved N and P are directly digested and absorbed by the cultured organisms or converted by the plankton and then digested and absorbed by the cultured organisms, and thus the seawater system in the culture device is basically purified.Meanwhile, the content of water dissolved oxygen in the water system of the culture device is increased by mixing water and gas.Thus, self-circulation of the water system in the culture device can be achieved, and no solid pollutant is discharged.

Description

technical field [0001] The invention relates to a seawater high-density culture device. Background technique [0002] Currently used mariculture ponds usually use a single species of organisms to breed, and in order to improve the utilization rate of bait, three-dimensional multi-species cultures are used, such as fish and shellfish combined culture, that is, both fish and shellfish are cultured in one pond , shellfish feed on fish leftover bait. The above-mentioned various breedings all produce a large amount of waste water, which contains various feed residues and fish excrement, which increases organic pollution such as N and P, and causes eutrophication of the water body. The higher the breeding density, the more serious the pollution, and increasing the breeding density is one of the directions of aquaculture technology. In order to solve this problem, people have proposed a variety of mariculture methods to solve water pollution. [0003] China's invention patent ap...
