High-efficiency ecological three-dimensional breeding method for rice field eels and pseudobagrus fulvidraco

Abstract

The invention relates to the technical field of breeding of rice field eels, in particular to a high-efficiency ecological three-dimensional breeding technology. The high-efficiency ecological three-dimensional breeding technology mainly comprises a set of complete ecological three-dimensional breeding mode for the rice field eels. The technology comprises contents such as site selection, net cage arrangement, aquatic plant planting and matching of fish species, wherein the matching of fish species is the core; a pool of about 10 mu is selected; micro-pores are arranged for oxygenation; knotless polythene net sheets are adopted by net cages; the area of each net cage is 6 m<2>, the depth is 1 m, and the depth of the part of the net cage immersed in the water is 0.5 m; the net cages are fixed by using brackets and are arranged in a straight line at an interval of 1 m and a row spacing of 2 m; the total area of the net cages does not exceed 50 percent of the total area; alternanthera philoxeroides are planted in 50-60 percent of the area of the net cages; after water is sterilized for 15 days, 5,000 pseudobagrus fulvidracos, each of which has the weight of 10 g, 1,000-2,000 loaches, each of which has the weight of 3-5 g, 100-500 silver carps, each of which has the weight of 100-500 g and 50-200 spotted silver carps, each of which has the weight of 50-500 g are bred per mu; 2 kg / m<2> of eels, each of which has the weight of 20-50 g, 5 loaches / m<2> and 1-2 toads, each of which has the weight of 10-100 g are bred in each cage; the eels seeds are soaked with 2 percent salt solution for 10-20 minutes before being put in the cages so as to prevent the occurrence of saprolegniasis.

Description

technical field [0001] The high-efficiency ecological three-dimensional cultivation technology of ricefield eel and yellow catfish developed by the invention relates to the technical field of ricefield eel cultivation, especially the aspect of healthy and efficient farming of ricefield eel and yellow catfish, especially the farming mode of ricefield eel. Background technique [0002] Swamp eel is a famous and precious freshwater fish with tender meat and rich nutrition. It has high edible and medicinal value. It is very popular in domestic and foreign markets. It is understood that the annual output of wild eels in my country is 40-50 tons, while the annual demand for rice field eels in the domestic market is more than 1 million tons. It is also more than 200,000 tons, so there is a big gap in the production of rice field eels, and the price has been high, and there is a trend of rising year by year. Therefore, regardless of the current production and sales situation or the ...

Problems solved by technology

[0005] Because the food thrown in cannot be eaten by rice field eels and yellow catfish in a timely manner. Over time, the water quality in the culture pond will be corrupted, and the occurrence of diseases and insect pests will be induced, so that the success rate of culture cannot be improved.
