Stereoscopic breeding method for small-size sea cucumber fries

[0040] (1) Select a three-dimensional sea cucumber culture area

[0041] In May 2020, a 30m*2m rectangular area was selected in the middle of the sea cucumber cultivation pond affiliated to Jinzhou Linghai Dalianhai Treasures Breeding Co., Ltd. as the cultivation area using the three-dimensional cultivation facility. The water depth of this area is 2m, which can be Change the water by natural tide; among them, the total number of algal cells in the water body of the sea cucumber culture area is ≥10 / mL;

[0043] ①Fix the stake

[0044] 7 wooden stakes were fixed at the two long sides of the breeding area, the distance between the wooden stakes was 5 meters, and the height of the wooden stakes was 3 meters;

[0045] ② Laying a sunshade net

[0046] After the stakes are fixed, lay three layers of shading nets (20 mesh) at the bottom of the breeding area and bind them to the stakes to prevent the shading nets fro

[0059] One, embodiment 1 and comparative example 1 sea cucumber culture situation

[0060] On the 10th day after seeding, the survival rate of sea cucumber larvae in the experimental area of ​​Example 1 was 90%, and the survival rate of sea cucumber larvae in the control experimental area of ​​Comparative Example 1 was 60%. On November 10 of that year, the average weight of sea cucumbers in the experimental area was 5.0±0.4g / head, while the size of sea cucumbers in the control experimental area was only 4.0±0.6g / head. The survival rate and growth rate of sea cucumber in the three-dimensional aquaculture area were significantly improved.
