In order to raise the level of standardization of pond culture and accelerate the development of efficient fisheries facilities and modern fisheries in the province, the Maritime and Fisheries Administration of Jiangsu Province formally issued the “Code for the Standardization of Aquaculture Pond Construction”.

I. Specification for the construction of freshwater aquaculture ponds 1 . The pond is contiguous with more than 300 acres, with convenient transportation, reasonable layout and regular shape.

2. The shape of the pond: In line with local conditions, it is generally rectangular with an aspect ratio of about 3:2.

3. Pond area: a single culture pond area is generally 10-20 acres is appropriate, according to the needs of aquaculture species and models, Tangkou can be adjusted, but generally does not exceed 30 acres.

4. Pool width: the width of the main dome is not less than 3 meters, and the width of the support dome is not less than 1.5 meters.

5. Ikeji slope: Yanpo ratio 1: 1.5-3 (stone masonry, except for the cement slab slope protection).

6. Pond depth: The average pond depth is not less than 2 meters, and the effective water storage is not less than 1.8 meters. The effective storage capacity of the culture ponds such as crabs and shrimps is not less than 1.5 meters, and the silt thickness at the bottom of the pond does not exceed 0.2 meters.

7. Pond revetment: In line with local conditions, it can be protected by a polyethylene mesh sheet, or by stone blocks, base stones, cement boards, etc.

8. Management houses: The breeding areas for the construction of management houses shall be constructed in accordance with the principles of beauty and practicality. Each management house shall have an area of ​​15 square meters or more and an altitude of 2.6 meters or more. Living, storage, and feed areas shall be separated.

9. Supporting facilities: Intake and drainage systems are separated, and supporting facilities such as roads, electricity, and breeding machinery are perfect. The power lines are safe and reliable.

10. Environmental requirements: A solid waste collection cylinder is installed for every 100 mu of ponds, collected and transported out of the culture area. Keep the environment green, clean and free from weeds and sundries.

II. Specification for the construction of mariculture ponds 1. The aquaculture ponds are contiguous with more than 500 acres, with convenient transportation, reasonable layout and regular shape.

2. The shape of the pond: In line with local conditions, it is generally rectangular with an aspect ratio of about 3:2.

3. Pond area: a single culture pond area is generally about 30 acres is appropriate, according to the needs of aquaculture species and models, Tongkou can be adjusted, but generally does not exceed 100 acres.

4. Pond ponds: The width of the main surface is not less than 3 meters and the width of the support surface is not less than 2 meters.

5. Tanggu slope: Inner slope ratio 1:2.5-3 (stone masonry, cement slab slope except).

6. Aquaculture pond depth: The average pond depth is not less than 2 meters, the effective storage is not less than 1 meter, and the silt thickness at the bottom of the pond does not exceed 0.2 meters.

7. Rehabilitation of the intake and drainage system in the aquaculture area: Inlet and outlet systems are independent. With the natural pond-feeding culture pond system, the total water intake capacity can fill the pond under its jurisdiction during a large tide period. The depth of the total drainage channel is 0.5 meters below the depth of the culture pond, and can be basically drained, with the maximum depth of water not exceeding 0.3 meters.

8. Aquaculture water purification treatment tank transformation: The contiguous aquaculture area above 3,000 mu shall be equipped with aquaculture water purification treatment tanks with an area not less than 5% of the total cultured area.

9. Management house: The management and breeding area needs to be built. The area of ​​each management house is more than 20 square meters, the height is more than 2.6 meters, and the living, storage and feed areas are separated.

10. Supporting facilities: roads, electricity, breeding machinery and other supporting facilities are perfect, and the power lines are safe and reliable.

11. Environmental requirements: Set up a solid waste collection cylinder for each 200-mu pond, transport it out of the culture area after centralized collection, keep the environment green and clean, and have no weeds or debris in the culture area.

III. Specification for the Construction of Recirculating Aquaculture Demonstration Project in Pond 1. The aquaculture pond is contiguous with more than 100 acres, with convenient transportation, reasonable layout and regular shape.

2. The shape of the pond: In line with local conditions, it is generally rectangular with an aspect ratio of about 3:2.

3. Pond area: a single culture pond area is generally about 10 acres is appropriate, according to the needs of aquaculture species, Tangkou can be appropriately enlarged, but generally not more than 30 acres.

4. Pool width: the width of the main dome is not less than 3 meters, and the width of the support dome is not less than 1.5 meters.

5. Pool slope: Tangpo inner slope ratio 1:1.5-3 (stone masonry, cement slab slope except).

6. Pond depth: The average pond depth should not be less than 2 meters, and the effective storage should be no less than 1.5 meters. The effective storage of the ponds such as river crabs and lobsters should be no less than 1 meter, and the silt thickness at the bottom should not exceed 0.2 meters.

7. Pond slope protection: In line with local conditions, the use of polyethylene mesh slope protection can also be used stone masonry, base stone, cement boards and other slope protection.

8. Purification pond construction: After the transformation of the scale of the farm should be used to clean the purification of aquaculture ponds, ponds planted aquatic plants, stocking water purification fish, shellfish, water purification. The area of ​​purification ponds is determined according to the species and mode of cultivation, and is generally not less than 8% of the aquaculture water surface.

9. Into the drainage system: the farm should build a separate inlet and drainage system that is compatible with the pond. The water inlet is located upstream of the drainage outlet and away from the drainage outlet. The culture tail water should be treated by purification ponds or water treatment equipment to achieve discharge or recycling.

10. Supporting facilities: The supporting facilities such as roads, electric power, aquaculture machinery, etc. are perfect, the power lines are safe and reliable, and small instruments and equipment such as water quality analyzers are arranged.

11. Management house: The area to be managed for the management of the use of breeding areas, each management room area of ​​15 square meters or more, the height of more than 2.6 meters, living, storage, feed areas are separated.
