Soilless propagation method of monopterus albus Zuiew

Abstract

The invention discloses a soilless propagation method of monopterus albus Zuiew. The soilless propagation method comprises the following steps: setting an opened net cage which is not less than 15m<2> in area in a pond or a greenhouse, putting a pile of round myriophyllum aquaticum in the net cage every 1.5m, putting two parent monopterus albus Zuiew in each pile of the myriophyllum aquaticum, feeding mixed bait every 2 to 3 days, and moving monopterus albus Zuiew fries attached to roots of Pistias tratiotes out of the net cage for independent breeding in 15th to 30th days after bubbling and spawning of the monopterus albus Zuiew. According to the soilless propagation method disclosed by the invention, the area of a monopterus albus Zuiew propagation net cage is enlarged, the myriophyllum aquaticum is utilized to replace soil so as to be used as a monopterus albus Zuiew nest, the number of parent monopterus albus Zuiew in the net cage is increased, the pairing success rate of the parent monopterus albus Zuiew is greatly increased, and meanwhile, a parent stress reaction is relieved by utilizing rich roots of the myriophyllum aquaticum, so that the influence of adverse weather is cast off, the propagation frequency is increased, and the soilless propagation method has the characteristics of convenience in operation, wide application range, high germination quantity per unit area, high economic benefit and the like.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a soilless propagation method for rice field eels. Background technique [0002] Field eel (Monopterus albus Zuiew) has high nutritional and medicinal value, and is one of the few traditional agricultural products that are in short supply. In the world, especially in Japan and South Korea, there are rumors of "medicine eel, longevity turtle, and loach ginseng". The annual export volume of rice field eel in my country has been growing steadily, approaching 200,000 tons; the annual demand in the domestic market is nearly 3 million tons. The huge imbalance between demand and production has made the phenomenon of blocking purchases, panic buying, and direct purchases in rural areas unabated, and the unit price has risen year by year. In addition, the large-scale use of chemical fertilizers and pesticides in agricultural production and the aggravation of water pollution and hard w...

Problems solved by technology

However, due to the special pairing habits of ricefield eels, there are few parents in small cages, many ricefield eels cannot be paired and reproduced, and are greatly affected by the weather, so the risk of stress response to parental eels is relatively high, so the spawning rate is unstable
