Semi-dry rice field for imitating eel cultivating system and cultivating method thereof

Abstract

The invention discloses a semi-dry rice field for imitating eel cultivating system and a cultivating method thereof, wherein the semi-dry rice field comprises a rice field body; an external circle fence and an internal circle fence are set inside the rice field body; a field-surrounding fish ditch and a separating fish ditch are set inside the internal circle fence; the rice field body is divided by the separating fish ditch into a plurality of rearing units; an outer side of the rice field body is provided with a maggot auto generating collector; after the rice field body is disinfected and tested with water, rice is planted on each of the rearing units according to the semi-dry planting technology; in addition, aquatic plants and aquatic animals are put in the field-surrounding fish ditch and the separating fish ditch; and eels are cultivated while intercropping fish, escargots and loaches, thus providing rich live bait fodder; and maggots are also cultivated for providing fodder for the eels. By adopting the semi-dry rice field for cultivating eels, the beneficial effects are that the mutual beneficial relationship between the aquatic plants and the aquatic animals is fully utilized; various waste material can be used in circulation; and the quality of the produced eels and fish is the same with that of the wild eels and fish, thus the whole cultivating system and cultivating method are ecological and environmental-friendly and the economic benefits are high.

Description

technical field [0001] The invention relates to the technical field of agricultural breeding, in particular to a semi-arid paddy field imitation wild eel breeding system and a breeding method thereof. Background technique [0002] Swamp eel is a famous freshwater fish widely distributed in my country. It is a delicacy and health food loved by consumers at home and abroad. It is very popular in domestic and foreign markets. According to the survey, the current annual demand in the domestic market is about 3-4 million tons. Japan and South Korea need to import 200,000 tons per year. The main source of goods in the market comes from wild fishing, but the over-fishing of wild rice field eels has been decreasing day by day. The kilogram has dropped to the current 1.5 kilograms, and many areas are on the verge of extinction. The increase in demand and the decrease in resources have made the supply of rice field eels increasingly tight, and the price even exceeds that of eels. In ord...

Problems solved by technology

[0003] In the early 1980s, China started the artificial breeding of rice field eels, mainly in small-scale ponds or gardens. In the end, due to the difficulty in controlling water quality and improper baiting, eel diseases frequently occurred, and the size of rice field eels was very different, which led to mutual cannibalism. However, the success of breeding was less, which seriously dampened the enthusiasm of the masses to raise ricefield eels; in the early 1990s, methods such as paddy field eel breeding, running water eel and vermicomposting, and running water farming appeared successively, but due to low catch rate, large investment, and disease Reasons such as the high rate have not been promoted in a large area in production; at present, a Chinese patent application w
