Abstract

The utility model relates to an intertidal pond for cultivating aquatics, which is provided with a pond composed of water stop sheets mutually connected. The inner side or the top of the pond is provided with a plurality of upright rods provided with surrounding nets whose upper parts overtop the top surface of the pond. The pond is below the sea level on the tide, and can be filled with sea-water after ebb; the surrounding nets can cause sea-water and bait of marine organisms to enter on the tide to oxygenate and add bait, and prevent enemy from invading; the surrounding nets can block off the culturing organisms after ebb to prevent running off, which can provide a good ecological environment for the survival of cultured organisms.

Description

Pond for cultivating aquatics

The utility model belongs to a kind of aquaculture facility, particularly a kind of on the intertidal zone aquatic product culturing pond at intertidal zone of aquaculture product.

The mariculture of prior art mainly contains deep water culture and mudflat aquaculture dual mode.Deep water culture is mainly based on raft culture and cage culture, promptly subtidal zone than deepwater field in throw in cage or the chest that is covered with fishnet, aquaculture product therein, aquaculture organism is a food with the biological feed in the seawater mainly.Save advantages such as bait, daily management expense are lower though this cultural method has, because cage is thrown in seawater, therefore, management difficulty is bigger, and the investment cost of breeding facility is also very high, also is subjected to the influence of storm wind and wave easily.

Mudflat aquaculture is exactly to build the pond on the supratidal zone in sea, then seawater is introduced the pond and comes aquaculture product.Aquaculture organism is a food with the artitificial food of throwing in mainly.This cultural method is compared with deep water culture, and the daily management expense is higher, and the quantity that bait is thrown in is big, and is difficult to grasp, and bait is thrown in few, can not satisfy the growth needs of aquaculture organism, causes poor growth; Bait is thrown in many, then pollutes Chi Shui easily, and anoxic in the water causes the water quality corruption, and aquaculture organism is raised the nose above water to breathe, even large quantities of death; The introducing of pond maritime interior waters or discharge main water pump or the ditch of relying on, when changing water, consumes energy not only, and mass rate of emission is also very slow, and the pond maritime interior waters can not often be changed, so, be difficult to the good water quality of maintenance, therefore, the input density of mudflat aquaculture is little, one mu of shrimp pond is thrown in the shrimp seedling and is no more than 20,000 tails, 5,000 to 10,000 of scallops, and survival rate is also lower, generally have only about 50%, thereby the output of mudflat aquaculture is lower, and 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.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and existing aquaculture facility is improved, and provides that a kind of cultivation density is big, output is high, cost is low, manageable aquatic product culturing pond at intertidal zone.

The utility model is achieved in that

It has a pond that is interconnected to constitute with water-stop sheet, installed inside in the pond has some vertical rods, and purse seine is housed in vertical rod, and the top of purse seine is higher than the top in pond, select suitable pond and purse seine height, it is provided with on the correct position of intertidal zone, can utilizes the exclusive characteristics of intertidal zone to carry out aquaculture, at the incoming tide, the pond is hidden under the sea, and in tide, firmly stand upright, after the ebb, hold full seawater in the pond; And purse seine can allow seawater and marine organisms enter at the incoming tide, and oxygenation increases bait, and prevents the intrusion of harmful animal, can block aquaculture organism at ebb tide, prevents to run off, thereby provides a good ecotope for aquaculture organism.

Another technical solution of the present utility model is, adopts concrete slab to be interconnected to constitute the pond, and some vertical rods are installed on the pond, and purse seine is housed in vertical rod, and the base of purse seine and the end face in pond link together.

The utility model compared with prior art has following advantage:

1, can utilize the exclusive characteristics of intertidal zone to carry out aquaculture, 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; Support the shrimp per mu yield and can reach more than 300 kilograms, 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 aquaculture organism has a good ecotope of ingesting 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.
