Abstract

The invention discloses a water quality ameliorant for pond culture turtle and a water quality improvement method, and belongs to the technical field of the aquaculture. The water quality ameliorant is formed by 18.2-20% of photosynthetic bacteria stoste, 0.4-1% of photosynthetic bacteria culture medium, 0.3-0.6 of yeast extractive, 1.5-1.7% of salt, 0.01-0.02% of selenium and the balance of water. The mode of applying on the bottom of the pond is used, the turtle amount and water volume in the pond are combined, and the application frequency and the application amount of the water quality ameliorant are rationally controlled, so not only the water quality condition can be effectively improved, the generation of the harmful bacteria is inhibited, and the oxygen content in the water is improved, but also the turtle diseases can be prevented, and the water quality ameliorant has special growth promoting function for the growth of the turtle.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and more specifically relates to a water quality improving agent and a water quality improving method for culturing soft-shelled turtles in ponds. Background technique [0002] Soft-shelled turtle has another name called turtle, foot fish, water fish, and its scientific name is Chinese soft-shelled turtle. It is a secondary aquatic reptile widely distributed in my country. Turtle is rich in fat, various amino acids, vitamins and minerals needed by the human body. Its meat is tender and delicious, and is deeply loved by consumers. Especially the wild soft-shelled turtle has very high nutritional value and excellent quality. The country with the most developed soft-shelled turtle farming abroad is Japan. The soft-shelled turtle aquaculture industry started in the middle of the 19th century, and was almost extinct after the defeat of World War II. It did not recover until 1955. After the 1970s...
