CN1297678A - Pond aquaculture method using circulation water - Google Patents

Abstract

During aquaculture, sewage from culture pond is purified in circular tank and biological filtering tank for reuse. By combining the merits of both enclosed industrial circulation water culture and traditional pond culture, the method of the present invention is environment protective, water saving, low in cost and good in aquaculture effect.

Description

Carry out the method for pond aquaculture with cycle water

The present invention relates to a kind of method of aquaculture.

The pond culture of fishes and shrimps is with a long history, be still one of topmost breeding way in the world at present, the trend that further expansion is arranged in its scale of developing country, although pond culture already has vast potential for future development, but because some problems appear in himself characteristics: form competition with worker, agricultural aspect soil and water resource, the pond sewage discharge is more and more serious etc. to the pollution of water environment.Therefore at western developed country, advocate at present and encourage growth batch production closed circulation water cultural technique, but the energy that it need be more, higher administrative skill and a large amount of fund inputs, particularly the cost of product is higher relatively, and the developing country that falls behind relatively at economic condition is difficult to popularize.

The object of the present invention is to provide a kind of environmental protection, water saving, cost is low, culture efficiency is good carries out the method for pond aquaculture with cycle water.

Technical solution of the present invention is:

A kind ofly carry out the method for pond aquaculture with cycle water, itself and prior art solutions are: the circular treatment of in the breeding process culturing pool being carried out following steps:

1. will culture pond sewage and put into circulatory pool, culturing in the circulatory pool has benthic mollusca or water plants;

2. the water that will handle through circulatory pool is played back to culture in the pond and cultures aquatic products.

To put into the biological filter earlier through the water after 1. step is handled and handle, and be played back to again to culture in the pond and culture aquatic products, be furnished with the filler of growth bacterium in the biological filter;

The filler that lays in the biological filter is plastic products or coir rope, stone, and the processing time of water in biofiltration is: 0.1～24 hour.

Step 1. in, benthic mollusca is clam or Mactra veneriformis, freshwater mussel, water plants is rice grass or water peanut, water processing time in circulatory pool is 3～300 hours.

The present invention the batch production closed circulation water can be cultured and the advantages separately of traditional pond culture be got up, and environmental protection, water saving, cost is low, culture efficiency good.

The invention will be further described below in conjunction with embodiment.

Embodiment 1:

A kind ofly carry out the method for pond aquaculture, in the breeding process culturing pool carried out the circular treatment of following steps with cycle water:

1. will culture pond sewage and put into circulatory pool, culture in the circulatory pool benthic mollusca--clam (or Mactra veneriformis) is arranged, breeding density is 10～1000 every square metre (examples: 10,100,300,500,800,1000), and water processing time in circulatory pool is 3～300 hours (example 3,10,50,100,180,260,300 hours);

2. will put into the biological filter through the water that circulatory pool is handled, be furnished with the filler of growth bacterium in the biological filter--plastic products (or coir rope, stone), the processing time of water in biofiltration is: 0.1～24 hour (example 0.1,1,5,8,12,16,20,24 hour);

3. the water that will handle through the biological filter is played back to culture in the pond and cultures aquatic products.

Embodiment 2:

Put water plants in the circulatory pool in a suitable place to breed--rice grass (or water peanut), culture pond sewage after circulatory pool is handled, directly be played back to culture in the pond and culture aquatic products, all the other are all with embodiment 1.

Claims (4)

1, a kind ofly carry out the method for pond aquaculture, it is characterized in that: the circular treatment of in the breeding process culturing pool being carried out following steps with cycle water:

1. will culture pond sewage and put into circulatory pool, culturing in the circulatory pool has benthic mollusca or water plants;

2. the water that will handle through circulatory pool is played back to culture in the pond and cultures aquatic products.

2, method of carrying out pond aquaculture with cycle water according to claim 1, it is characterized in that: will put into the biological filter earlier through the water after 1. step is handled and handle, be played back to again to culture in the pond and culture aquatic products, be furnished with the filler of growth bacterium in the biological filter.

3, according to claim 2ly carry out the method for pond aquaculture with cycle water, it is characterized in that: the filler that lays in the biological filter is plastic products or coir rope, stone, and the processing time of water in biofiltration is: 0.1～24 hour.

4, according to claim 1 or 2,3 described methods of carrying out pond aquaculture with cycle water, it is characterized in that: step 1. in, benthic mollusca is clam or Mactra veneriformis, freshwater mussel, and water plants is rice grass or water peanut, and water processing time in circulatory pool is 3～300 hours.
