Problems solved by technology

Although this method can better solve the problem of moss produced in the freshwater shrimp culture process, this method is more complicated, time-consuming and laborious, and has a higher cost, and this method is only aimed at the prevention of green shrimp pond moss, and it is not suitable for other species of shrimp culture. And the removal and control of the moss that has grown during the breeding process is not good
At present, methods such as manual salvage and chemical drug suppression are mostly

Example Embodiment

[0017] Example 1:

[0018] The pond area of ​​the Japanese shrimp high-level pond is 1 mu (length, width and depth are: 30m, 22m, 2m respectively, and the slope of the pond wall is about 60 degrees), and the water depth is 1.7m. During the breeding process, it was found that moss was growing on the wall of the high-level pond, and the water level of the pond was lowered to 1.2m in time, so that about 30% of the moss was exposed outside the water body.

[0019] Cut the black plastic film according to the size and specification of the high-level pond in this example, and roll up the edge of the cut black plastic film to make a cylindrical bag with a size of 2 cm directly. Finally, the treated black plastic film was spread on the pool wall of the high-level pool, and the black plastic film was fixed by the surface tension of water and the weight of fine sand. The black plastic film can protect from light, prevent the moss from photosynthesis, and inhibit its growth. The cylindri...

[0022] Example 2:

[0023] The pond area of ​​the Japanese shrimp high-level pond is 1 mu (length, width and depth are: 30m, 22m, 2m respectively, and the slope of the pond wall is about 60 degrees), and the water depth is 1.7m. During the breeding process, it was found that moss was growing on the wall of the high-level pond, and the water level of the pond was lowered to 1m in time, so that about 35% of the moss was exposed outside the water body.

[0024] The black plastic film is cut according to the specifications of the high-level pond in this embodiment, and the edge of the cut black plastic film is rolled up and made into a cylindrical bag with a size of 3 cm directly. The bag was sealed, and finally the treated black plastic film was spread on the pool wall of the high-level pool. The black plastic film can protect from light, prevent the moss from photosynthesis, and inhibit its growth. The cylindrical bag containing the gravel can not only fix the black plastic fil...

[0027] Example 3:

[0028] The pond area of ​​the Japanese shrimp high-level pond is 1 mu (length, width and depth are: 30m, 22m, 2m respectively, and the slope of the pond wall is about 60 degrees), and the water depth is 1.7m. During the breeding process, it was found that moss was growing on the wall of the high-level pond, and the water level of the pond was lowered to 1.2m in time, so that 32% of the moss was exposed outside the water body.

[0029] Cut the black plastic film according to the specifications of the high-level pond in this embodiment, and roll up the edge of the cut black plastic film and make a cylindrical bag with a size of 2 cm directly. The bag was sealed, and finally the treated black plastic film was spread on the pool wall of the high-level pool. The black plastic film can protect from light, prevent the moss from photosynthesis, and inhibit its growth. The cylindrical bag filled with fine sand can not only fix the black plastic film, but also preve...

Abstract

The invention relates to a method for controlling moss in a penaeus japonicas higher-place pond. The method comprises the following steps: (1) when mosses are found on pond walls of a higher-place pond in an intensive culture process, reducing water level of the higher-place pond, to make 30% to 35% mosses expose out of water; (2) fixing and paving black plastic films along the peripheral pond walls of the higher-place pond; (3) after that, putting amino acid fertilizer water paste in the water of the higher-place pond to make water rich every other 3-5 days; (4) after 7-10 d, after the mosses on the pond walls almost die, putting away the black plastic films on the pond walls; (5) filling water in the higher-place pond, and water level recovering to initial height, then putting aquaculture probiotics into the pond every other 3-5 days, to make water transparency of the water reach 30-40 cm, and pH value being stabilized between 7.8 and 8.2. The method is simple and easy to operate, and is environmentally friendly and economical, and effectively controls mosses by the method of removing the mosses in an earlier stage and restricting the mosses in the later stage. The method provides a stable ecological system for pond culture of penaeus japonicas in the higher-place pond, and thoroughly eliminates the mosses and controls growth of the mosses.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for controlling moss in high-level ponds of Penaeus japonicus. Background technique [0002] Penaeus japonicus, scientifically known as Penaeus japonicus, is widely distributed in the coastal waters south of the Yangtze River in my country. Because of its tender meat, delicious taste, and rich nutrition, it has become the best among many prawn species and is deeply loved by consumers at home and abroad. In recent years, on the basis of high-level pond culture of Penaeus vannamei in southern my country, a new high-level pond intensive culture model has been developed for the living habits of Penaeus japonicus. Practice has proved that the unit mu output of Penaeus vannamei can exceed 400kg, and the output value per mu It can reach more than 60,000 yuan. [0003] At present, the intensive culture mode of Penaeus japonicus in high-level ponds has been gradually populari...
