Embodiment 1
[0018] (1) Select the breeding frame: select the breeding frame made of plastic material, the specification is length × width × height equal to 60 × 45 × 50 cm, the upper part of the breeding frame is open, surrounded by fences, and the distance between the fences is 5 mm , the bottom is covered with uniform round holes, the diameter of the round holes is 5 mm, and a 20-mesh screen leak-proof film is laid on the bottom of the culture frame, and 20 cm thick sea sand with a particle size of 2.5 mm is laid on the leak-proof film, and then Lay 30 cm thick sea sand with a particle size of 1.5 mm;
[0019] (2) Seed selection, delivery, management and harvesting: select 210,000 medium seedlings with a size of 1.0-1.5 cm, transport them to the seedling field with oxygen in shrimp seedling bags, and put about 20,000 seedlings in each bag, and put them in the Shallow sea culture is carried out in 500 breeding boxes, and 400-500 seedlings are placed in each box. During the period, the se...
Embodiment 2
[0021] (1) Select the cultivation frame: select the cylindrical cultivation frame prepared by plastic material, the diameter of the cultivation frame is 50 cm and the height is 45 cm, surrounded by fences, the distance between the fences is 10 mm, and the bottom is covered with uniform A round hole with a diameter of 10 mm. A 20-mesh screen leak-proof membrane is laid on the bottom of the breeding frame. 20 cm thick sea sand with a particle size of 2.5 mm is laid on the leak-proof membrane, and a 30 mm thick sand is laid on it. Sea sand with a particle size of 1.5 mm;
[0022] (2) Seed selection, placement, management and harvesting: select 2.8 million seedlings in the pond, with a size of 1.0-1.5 cm, transport them with oxygen in a bag of shrimp seedlings, put 15,000-20,000 seedlings in each bag, and put them in 6000 Shallow sea culture was carried out in 3 breeding boxes, and 450-500 seedlings were placed in each box. After 51 days of breeding, the size of the seedlings reac...
Embodiment 3
[0024] (1) select the breeding frame: same as embodiment 1;
[0025] (2) Seed selection, placement, management and harvest: 80,000 seedlings in the selected sea area, with a size of 3-4cm, transported with oxygen in shrimp seedling bags, 300-400 seedlings per bag, and stocked in 1,000 breeding boxes During the shallow sea culture, the breeding frame was cleaned once every 2-3 months. When the culture reached five months, it encountered the influence of large marine algae Sargassum, which caused red tides in some ocean areas, which affected the giant otter. For the cultivation of clams, at this time, the whole cultivation frame was hoisted and moved to an unaffected sea area to continue cultivation. The cultivation time was 9 months, and 4716 kg of adult clams were harvested, and the survival rate of cultivation was 94.3%.
