Embodiment 1

[0025] A kind of mixed cultivation method of loach rice field eel, the operation steps of its concrete cultivation method comprise as follows:

[0026] (1) The building pond area is 2 mu, and the bottom surface of the pond and the wall are paved with cement after being paved with stone slabs, and the net depth of the pond is 1.2m. The slope of the wall of the pond is set to 45°, and paved on the wall 7-12cm thick fine sand and 0.32m thick retting silt are spread at the bottom of the pool, and 10% lime water is used for disinfection. At the same time, there is a water inlet on one side of the wall and an outlet on the other end. The corners on both sides of the water inlet are provided with 50cm high feeding platforms;

[0027] (2) The pond stores water, and its depth of water storage is 1m. Then, after 15 days of spreading 160kg of decomposed poultry manure and 2kg of urea in the pond, carry out strong water and sedimentation treatment, and then cultivate 6 pieces of 5m each. ...

Abstract

The invention discloses a mixed aquaculture method of loaches and rice field eels. The mixed aquaculture method comprises the following steps: constructing a pond with a water inlet and a water outlet, paving sludge in the pond, storing water, cultivating water, feeding aquatic plants, putting in disinfected fish fries, then specially quantitatively feeding baits at fixed time regularly, and performing water changing and disease prevention. The method is simple and practical, easy to operate, low in aquaculture cost, sufficient in dissolved oxygen of a water body and multiple in nutrients of the water body; fat and strong loaches can be beneficially cultivated by matching feeding of livestock offal; the 'three fixed' fed baits can meet the growth demands of loaches; and in addition, the additives in the baits can prevent the occurrence of epidemic diseases with the efficiency of up to 95%, the yield per mu of loaches can be increased by 6-8% after loaches are normally cultivated for seven months, each loach is 15cm long, the yield per mu of rice field eels is increased by 5-7%, the average weight of each rice field eel is above 80g, and the economic benefits can be increased by 15%.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a mixed culture method of loach and eel. Background technique [0002] Loach belongs to Cypriniformes, with a slender body, a slightly rounded front end, and a flat back end. Body gray and black, head small. Mouth small, inferior, horseshoe-shaped. Eyes small, no undereye thorns. Must be 5 pairs. The scales are extremely small, round and buried under the skin. Body color often varies due to different living environments. There are also many black spots on the head and each fin, the spots on the dorsal and caudal fin membranes are arranged in rows, and there is an obvious black spot at the base of the caudal peduncle. The other fins are grayish white. Loach likes to inhabit the bottom of still water, often appearing in the silt surface rich in plant debris at the bottom of lakes, ponds, ditches and paddy fields, and has strong adaptability to the environment.
