Problems solved by technology

However, the biological composition of the cement pool is relatively simple, the conversion rate of matter and energy is slow, and its water quality fluctuates greatly. It is necessary to maintain the goodness and stability of the water quality by changing the water continuously
More importantly, the cement has no bottom quality at the bottom of the pond, which makes it very difficult to cultivate aquatic plants, which affects the ecological service function of aquaculture.

Embodiment Construction

[0023] 1. Pond preparation

[0024] Choose a cement pool without a soil substrate, and disinfect it with bleaching powder at a dosage of 20g / m 3 , add water to dissolve the whole pool and splash.

[0025] 2. Production of Elodea colonization cages

[0026] The cage body is made of 1×1cm net mesh, the specification is 60cm×20cm×5m, and the cage body is fixed in the cage with 10 equal intervals of 60cm×20cm wire frame for support, and the middle part of each distance is 5cm×15cm square entrance and exit. The prepared cage is also sterilized with the above-mentioned disinfection method.

[0027] 3. Elodea colonization

[0028] Collect Elodea algae from the wild or from ponds where Elodea algae species are specially grown.

[0029] Use 1 / 10,000th of Promoteril to soak the Elodea algae in a medicinal bath for 15-20 minutes to kill all kinds of pathogenic bacteria and ciliates.

[0030] Put Elodea into the cage body from the side opening of the cage body, and place each ...

Abstract

The invention discloses a method for planting elodea muttallii in the concrete pond without oil. The method comprises the steps of pond preparing, elodea nuttallii planting cage body making, eloda nuttallii planting and daily maintenance. Elodea nuttallii cultivation in a cement pond without bottom materials such as soil is achieved by combining the culture practice of crustaceans such as shrimps and crabs according to the growth characteristic of the elodea muttallii. The elodea muttallii which is planted through the method has the advantages that the elodea muttallii growth is fast, the operation is easy, the material cost is low, and the ecological effect is good, and the method for planting the elodea muttallii in the concrete pond without the the oil has an important meaning on cement pool ecological cultivation of aquatic animals.

Description

technical field [0001] The invention relates to a method for soilless cultivation of Elodea in cement pools. In practical application, the method has the characteristics of fast growth of algae body, simple operation, low material consumption, good ecological effect and the like, and belongs to the application field of aquaculture technology. Background technique [0002] Shrimp and crabs and other crustaceans are important aquaculture objects in the world, and my country is the largest shrimp and crab breeding country in the world. In 2013, my country's crustacean breeding volume reached 3.77 million tons, of which the output of Chinese mitten crab reached 729,900 tons, with an output value of nearly 40 billion yuan (compiled by the Fishery Administration Bureau of the Ministry of Agriculture, 2014 China Fishery Statistical Yearbook, p. 30). At present, in the breeding process of shrimp and crabs (such as Chinese mitten crab, giant river prawn, and Procambarus clarkii), aqu...
