Description

Aquatic product culturing pond at intertidal zone

The invention belongs to the mariculture technology field, particularly a kind of on the intertidal zone aquatic product culturing pond at intertidal zone of aquaculture product.

At present, because world ocean is fished for technology rapid development, living marine resources are more and more poorer, and therefore, mariculture industry also just more and more is subject to people's attention.Existing mariculture mainly contains deep water culture and mudflat aquaculture dual mode.

Deep water culture is mainly based on breed such as raft formula or net cages, promptly subtidal zone than deepwater field in throw in the cage be covered with fishnet, aquaculture product therein, aquaculture organism mainly by the biological feed in the seawater for food, during culturing, also need according to circumstances manually to throw in bait, because cage is thrown in seawater, therefore, the management difficulty of this cultural method is bigger, the investment cost of facility is also very high, also is subjected to the influence of storm wind and wave easily.

Mudflat aquaculture is exactly to build to culture the pond on the supratidal zone in sea, seawater is introduced the breed pond again and is come aquaculture product.Because culturing the pond builds on supratidal zone, therefore, the pond maritime interior waters will lean on water pump or ditch to introduce or discharge, when changing water, need to consume a lot of energy, thereby, during culturing, the pond maritime interior waters can not be changed everyday, so, being difficult to make the good water quality of maintenance in the pond, this has not only limited the input density of aquatic products, also be unfavorable for growing of aquaculture organism, simultaneously, this cultural method can not make full use of big marine abundant biological feed, and the bait of aquatic products mainly solves by throwing in artitificial food, and the quantity that drops into bait is difficult to grasp, bait is thrown in few, can not satisfy the growth needs of aquaculture organism, and bait is thrown in many, then pollute Chi Shui easily, cause the water quality corruption, anoxic in the water, aquaculture organism is raised the nose above water to breathe, even large quantities of death, therefore, the input density of mudflat aquaculture is little, and one mu of shrimp pond is thrown the shrimp seedling and is no more than 20,000 tails, 5,000 to 10,000 of scallops, survival rate is lower, generally have only about 50%, thereby the output of mudflat aquaculture is lower, the per mu yield of shrimp pond generally is no more than 200 kilograms, and the scallop per mu yield is no more than 300 kilograms.

Above-mentioned said deep water culture is that the subtidal zone in the sea carries out, and mudflat aquaculture is to carry out on the supratidal zone in sea, and the zone-intertidal zone between supratidal zone and the subtidal zone is vast, a undeveloped zone still then, and flood tide in the intertidal zone comes water, full of vitality; Ebb water is done, and marine organisms are difficult to existence, and many characteristics different with supratidal zone and subtidal zone are arranged, tiding, and one day twice, endless, both cultured and brought very big difficulty to aquatic products, also culture the very favorable condition of having created to aquatic products.

The objective of the invention is to make full use of the exclusive characteristics of intertidal zone, improve existing aquaculture facility, provide that a kind of cultivation density is big, output is high, cost is low, manageable aquatic product culturing pond at intertidal zone.

The present invention is achieved in that

It has a pond that is surrounded by the latent dam that is embedded on the intertidal zone, and the top in pond is lower than sea at the incoming tide; Inboard in the pond is provided with purse seine, and the bottom of purse seine is imbedded in the silt particle, and the top of purse seine is higher than sea at the incoming tide; Latent dam is being hidden under the sea at the incoming tide, and firmly stands upright in spring tide, but can hold a full pond seawater after the ebb; And purse seine can allow seawater and marine organisms bait enter at the incoming tide, and oxygenation increases bait, and prevents the intrusion of harmful animal, can block aquaculture organism at ebb tide, prevents loss, thereby the good ecotope of an existence is provided for aquaculture organism.

In order to prevent in the outside in pond the bigger protecting wire net of porose order to be set also the destruction of rising, purse seine suffers macro-organism and other foreign objects at ebb tide, the bottom of protecting wire net is imbedded in the silt particle, and the top of protecting wire net is higher than sea at the incoming tide.

The present invention compared with prior art has following advantage:

1, make full use of the intertidal zone exclusive characteristics, high tide changes the water oxygenation for the breed pond, one day twice, fundamentally solved the problem of water quality corruption, make and remain good water quality in the pond, both helped growing of aquaculture organism, also help to improve the survival rate of aquaculture organism, simultaneously, also increased substantially cultivation density, shrimp seedling 3～40,000 tails can be thrown in one mu of pond, and scallop is more than 150,000, the culture shrimp per mu yield can reach more than 300 kilograms, and scallop and other shellfish per mu yields can reach more than 5000 kilograms.

2, at the incoming tide, there are a large amount of marine organisms to enter in the pond in the seawater thereupon, for aquaculture organism provides multiple high-quality bait, ensured that material culture has a good ecotope of ingesting for a long time and surviving, not only promoted growing of aquaculture organism, also be particularly suitable for the mixing three-dimensional culture of multiple fish, shrimp and shellfish, make it share a pond seawater, with being subjected to the preferential of morning and evening tides, absorb different bait, each is in his proper place, simultaneously, also can save artitificial food greatly, reduce aquaculture cost, obtain good economic benefit.

3, after the ebb, anhydrous outside the breed pond, be convenient to throw seedling, Qing Chi, results, observation and management, grasp the growing state of aquaculture organism in the pond at any time, it is accurate, convenient that bait is thrown in, and needn't worry to run off and corrupt water quality.

4, pond structure is simple, easy construction is rapid, material can be gathered materials on the spot, suit measures to local conditions, if with 100 mu be a pond (260 meters * 260 meters), then build length and be about 10 meters/mu, if join near many ponds, then build length and can contract to 6 meters/mu, the one-time construction expense is no more than 2000 yuan/mu, only is 667 yuan of/year mus by depreciation in 3 years.
