Abstract
The invention belongs to the field of seawater cultivation engineering and particularly discloses a big fixed net cage for cultivating seawater fishes and a using method thereof. The big fixed net cage for cultivating the seawater fishes and the using method thereof solve the problems of poor anti-typhoon capability, more diseases, high making cost and the like of the current net cages. Piles of the net cage are distributed along the periphery; a net encloses the piles to form a cage structure; the upside and the lower side of the net are coiled by an upper net cable and a lower net cable; the tops of the piles are connected with diagonal tension cables II; the upper parts of the piles are connected with diagonal tension cables I; and the tops of the corresponding piles are connected by transverse cables. By piling piles under the sea and providing the transverse cables, the diagonal tension cables, the upper and lower cables of the nets to fix the big nets, the cultivating capacity of the net cage is improved, the cultivating cost is reduced, the quality of the cultivated fishes is improved and the cultivating environment is protected. The big fixed net cage for cultivating the seawater fishes and the using method thereof make a full use of and maintain a good ecological environment for cultivation, produce the highly qualified seawater fishes, prevent the cultivating area from being polluted and prevent the occurrence of diseases in the aquaculture, improve the living environment for the cultivated fishes and reduce losses due to natural disasters.
Description
Technical field
The invention belongs to mariculture engineering field, is a kind of big fixed net cage for cultivating seawater fishes and using method thereof specifically, and it is by the fixedly etting of post of driving piles in the seabed, increases the large cage method for designing of fish culture water body.
Background technology
Fish culture in net pen is a kind of breeding way of big waters intensification, and it freely exchanges by the inside and outside water body of net cage, forms the ecotope of a suitable fish growth in net cage, and carries out a kind of method of high-density breeding.Characteristics such as it has the waters that makes full use of natural waters and bay, do not account for arable land, land, yield per unit area height, the culture-cycle is short, food conversion is high, culture that object is wide, convenient operation and management, efficiency height, intensification degree height and remarkable in economical benefits.The fish culture net cage that China adopted can be divided into offshore small-sized net cage and deep water wind wave resistance net cage according to its suitable marine site.Small-sized net cage is essentially square or rectangle floating cage, generally based on 3 * 3 * 3m and 3 * 6 * 3m; The main type of deep water wind wave resistance net cage has the latent formula net cage of gravity type net box (comprising floating and elevation (over-and-under) type), drift line type net cage and dish, and wherein the ability of resisting stormy waves with HDPE gravity lifting net cage and the latent formula net cage of steel construction dish is the strongest.But the cost of deep water wind wave resistance net cage reaches more than 1,000,000 yuan, and general raiser and enterprise are unaffordable.Maximization, the large of the development trend net cage of external net cage cultured fishes, this cultures the marine site for expanding, and reduces aquaculture cost, and near natural, ecological, it is highly beneficial to improve the fish quality.
Summary of the invention
The big fixed net cage for cultivating seawater fishes and the using method thereof that the object of the present invention is to provide cultivating seawater fishes to use solve the existing Anti-Typhoon ability of net cage, disease problems such as many, cost height take place.
For achieving the above object, the technical scheme taked of the present invention is:
A kind of big fixed net cage for cultivating seawater fishes, this net cage be provided with etting, pile, tiltedly draw guiding principle I, headline, tiltedly draw guiding principle II, laterally guiding principle, infraclass, pile is along distributing all around, pile outer cover etting surrounds case structure, etting is raised to the higher plane of principle and the etting infraclass around etting respectively up and down, the pile top is connected with tiltedly drawing guiding principle II, and pile top is connected with tiltedly drawing guiding principle I, and the top of corresponding pile connects by horizontal guiding principle.
Described big fixed net cage for cultivating seawater fishes, etting upper edge have the door of the etting of coming in and going out, and it is slip-knot that door place etting is raised to the higher plane of principle.
Described big fixed net cage for cultivating seawater fishes, the pile top is connected with an end that tiltedly draws guiding principle II, tiltedly draws the other end of guiding principle II to fix by anchor III, and pile top is connected with an end that tiltedly draws guiding principle I, tiltedly draws the other end of guiding principle I to fix by anchor I.
Described big fixed net cage for cultivating seawater fishes, pile top are apart from 1/3 place, pile top.
Described big fixed net cage for cultivating seawater fishes is provided with drift net around net cage.
Described big fixed net cage for cultivating seawater fishes is provided with bait table in net cage, bait table is fixed by anchor II.
The using method of described big fixed net cage for cultivating seawater fishes is selected suitable sea area, and fixedly pile is fixed on etting on the pile, and in the periphery of net cage affiliated facility is set.
Described suitable sea area is meant the inner bay that stormy waves is less, trend is unimpeded, and substrate is sandy or husky mud substrate, the subtidal zone marine site of silt content 60%～80%.Shallow water deeply should be more than 3 meters in the net cage during spring low water; Flow to straight, flow velocity at 1～1.5 meter per second, flow velocity is 0.2～0.5 meter per second in the net cage after baffle.Seawater water temperature: 8～30 ℃; Seawater salinity: should be 15～30; Seawater transparency: 0.5～1.5 meter.
Described fixedly pile is meant that cage netting fixes with the method for beating the soldier piles post.The pile height should exceed spring tide tide face 1-3 rice.Pile is diameter 4-15cm, long 15-16 rice, squeezes into seabed mud 2-3 rice, and 2-3 rice surfaces on the high water time.Each net cage 100-200 pile post, spacing is made a call to 1 pile post for about 2 meters.The etting of net cage is installed up and down by the etting infraclass and etting is raised to the higher plane of principle, and draws horizontal guiding principle between corresponding pile, to increase the pile fastness.Etting is raised to the higher plane of principle to strain etting is opened naturally, is fixed on pile top, etting headline height 1 meter on high water spring tide; Tiltedly draw guiding principle in soldier piles column top and place, top bundle, piling post in tension back is fixed on the seabed.
