Method for culturing rice field eel

Abstract

The invention discloses a method of culturing eels, comprising the steps of: firstly adopting places with abundant water source of a pond, a pool, a ditch, a rice paddy and the like as a culture pond; secondly, arranging a species complementary culturation platform, throwing in angleworms; thirdly, preparing the pecies complementary culturation platform, which is arranged in a cinquefoil form, the platform is higher than water surface, the culturation platform is mixedly stacked, stacking time is decided on air temperature, the angleworm are inoculated at 1 cm near the water surface after retting, the eels can freely ingest after 20 days, added for one time according to diet consumption of the culturation platform. The invention method is simple, convenient in operation, wide in material source, low in cost of investment, low in labor intensity, high in producing efficience.

Description

technical field [0001] The invention belongs to the field of ecological eel breeding, and more specifically relates to a method for eel breeding. Background technique [0002] At present, there are the following kinds of rice field eel feed at home and abroad: one is to use paddy fields to breed rice field eels, which is an effective way for farmers to win two birds with one stone. One is to heighten and reinforce the ridge on the basis of the original field to achieve no water seepage; the other is to dig a set of ditches around the field with a width of 5m and a depth of 1m, and in the middle of the field dig "ten" or The "well" shaped small ditch is 50cm wide and 30cm deep, and communicates with the surrounding ring ditch; the third is to improve the inlet and drainage system, and install fast fish blocking facilities at the inlet and outlet to prevent fish from escaping. The method yield is low, and economic benefit is relatively poor. The other is natural feed, such a...

AI Technical Summary

Problems solved by technology

One is to heighten and reinforce the ridge on the basis of the original field to achieve no water seepage; the other is to dig a set of ditches around the field with a width of 5m and a depth of 1m, and in the middle of the field dig "ten" or The "well" shaped small ditch is 50cm wide and 30cm deep, and communicates with the surrounding ring ditch; the third is to improve the inlet and drainage system, and install fast fish blocking facilities at the inlet and outlet to prevent fish from escaping. The method has low yield and poor economic benefit

The other is natural feed, such as small miscellaneous fish, shrimp, earthworms, etc., affected by resources and seasons, these feeds are often not supplied normally; the other is to use eel or soft-shelled turtle feed instead of natural feed to feed eels, such as Zhou Tianyuan Wang Yufeng (1996) published the feed formula disclosed in the paper "Development of Full-price Compound Feed for Rice Field Eel". Although these formula feeds have solved the feed outlet for large-scale artificial breeding of rice field eels, the cost of feeding High, the quality of rice field eels is low, and the taste is quite different from natural eels, which seriously restricts the healthy development of rice field eels production
