Embodiment 1

[0020] Adopt the method for regulating water quality in the prawn high-level pond culture of the present invention by utilizing Pterococoons, cultivate Pterococoons to regulate water quality according to the following steps:

[0021] (1) Cement pond cultivation of Pteropycodonoid algae: The area of ​​the cement pond for cultivating Pteropterosa cocoonoid algae is 20m 2 , the pool is 1.2m deep. After the cement pool is cleaned, add 1.0m of filtered seawater, then disinfect the pool water with 200g of strong chlorine, and then neutralize it with 80g of sodium thiosulfate after 24 hours and continue to aerate for 8 hours. After all the residual chlorine in the water disappears, add NaNO 3 640g, NaH 2 PO 4 100g, Na 2 SiO 3 240g and FeCl 3 9g, 240mL of boiled fish sauce. Then inoculate the cement pond with the algae grown indoors.

[0022] (2) Cultivation of cocoon-shaped algae high level pool: the area of ​​high level pool is 2000m 2 , the depth of the pond is 1.85m, and ...

Embodiment 2

[0025] Adopt the method for regulating water quality in the prawn high-level pond culture of the present invention by utilizing Pterococoons, cultivate Pterococoons to regulate water quality according to the following steps:

Abstract

The invention relates to a method for cultivating amphiprora alata used for regulating water quality in higher-place pond prawn cultivation, and belongs to the technical field of aquaculture. According to the features of a long growth period and stable cultivation water quality of the amphiprora alata, before shrimps are put into a higher-place pond, the amphiprora alata is cultivated directionally in the higher-place pond, the method includes the specific steps that the amphiprora alata is cultivated in a laboratory firstly, then is cultivated in an outdoor cement pond and is inoculated into the higher-place pond to be cultivated finally; after being cultivated in the higher-place pond for 7 days to 8 days, the amphiprora alata becomes dominant species, and the shrimps can be put into the higher-place pond. The method is simple and convenient to operate, the technology is easy to master, the mode that the cultivation water ecological balance is sustained through large-scale discharge and large-scale irrigation in traditional higher-place pond prawn cultivation is avoided, the cultivation pond water is tawny, the transparency is moderate, the ecological system can be kept in a stable state for a long time, the usage amount of chemicals and diseases are reduced obviously, the rate of successful cultivation is increased, the cultivation cost is reduced, the economical benefit is remarkable, and the body colors of obtained prawns are good.

Description

technical field [0001] The present invention relates to a method for adjusting the culture environment by cultivating microalgae with wide salinity, stable population and strong adaptability in the high-level pond culture of prawns, and specifically relates to a method for cultivating cocoon-shaped algae in the high-level pond culture of prawns to regulate water quality , belongs to the field of aquaculture technology. Background technique [0002] Intensive culture of prawns is a culture mode that uses modern engineering, chemistry, biology, electromechanical, automation and the use of environmentally friendly feed and other latest technological means to carry out high-density culture of prawns under artificial control conditions. In recent years, in order to pursue high yield in the process of shrimp farming, a large amount of artificial feed has been put in while increasing the breeding density, causing a large amount of residual bait, shrimp feces and dead biological deb...
