Problems solved by technology

Existing single-type fish fertilizers and compound-type fish fertilizers also have a common shortcoming, that is, they cannot kill harmful bacteria and insects, so they lack the effect of effectively preventing and controlling fish diseases
The microbial compound fish fertilizer can increase the content of beneficial bacteria in fish ponds and effectively reduce the occurrence of fish diseases. At present, there is no report on the special use of this compound microbial fish fertilizer

Embodiment 1

[0018] A method for cultivating rice field eels by using a multifunctional compound feed, comprising the following steps:

[0019] 1) Construction of the breeding pond: the Yao breeding pond is oriented east-west, with an aspect ratio of 3:2, and an area of ​​2000-10000 m 2 , the height of the pond ridge is 1.8m-2.0m, the water level can be stabilized at 1.4-1.5m for a long time, and the ponds with perfect drainage facilities are; If there are no loopholes, then use quicklime to clear the pond. When the depth of the pond is 7-10cm, use quicklime 1125-2250kg / hm 2 , if the pool water cannot be drained, clear the pond with bleaching powder, inject new water 7 days after clearing the pond, filter the injected new water, apply base fertilizer after water injection, and cultivate water quality. The method is to pile up chicken manure, pig manure, etc. on the four corners of the pool Organic fertilizer, dosage 2250~ 3000kg / hm 2 , after 5~7 days of fertilization, rice field eels can...

Embodiment 2

[0025] The preparation method is the same as in Example 1.

[0026] In the juvenile stage of growing rice field eels, pull them out and raise them separately in five pools, 300 in every pool, put in the microbial rice field eel fertilizer and common rice field eel in the embodiment of the present invention 1 respectively in the four pools according to the dosage of 200kg per mu Fertilizer (control 1, produced from Beijing Century Arms Biotechnology Co., Ltd. ), the other pond did not put ricefield eel fertilizer (control 2), but put in the same amount of common fish food, and the rest of the feeding amount was the same, and the cultivation environment was the same. After 2-4 months of breeding, the production and the growth status of ricefield eel were compared , specifically as shown in Table 1 and Table 2:

[0027]

[0028]

[0029] Through the comparison of Table 1 and Table 2, it can be found that adding the compound microbial fertilizer of the pre...

Abstract

Disclosed is a method for breeding finless eel by utilizing multifunctional compound feed. A culture pond trends eastwards to westwards, is 3:2 in the ratio of length to width, 2000-10000 square meters in area and 1.8-2.0m in pond bank height, has a water level stabilized at 1.4-1.5m for a long time, and is a pond with complete water inflow and water drainage facilities; 10-15 days before the finless eel is put into the pond, the pond is sterilized, water in the pond is pumped out, loopholes are detected, the pond is cleaned with quick lime, and the finless eel is fed with the multifunctional compound feed. Discovered by comparison, by the aid of the multifunctional compound microorganic feed, quick growth of the finless eel can be facilitated, EPA (eicosapentaenoic acid) content is increased, illness of the finless eel is decreased, shrimps died of disease are decreased, beneficial microorganisms in the water are increased, and quality and mass are increased finally.

Description

technical field [0001] The invention relates to an aquaculture method, in particular to a method for cultivating rice field eels by using multifunctional compound feed. Background technique [0002] Field eel, belonging to Cyprinidae and Loachidae, is a small economic fish and belongs to warm water fish. The growth water temperature is 15~30℃, the optimum water temperature is 22~28℃, and the water temperature is higher than 32℃. Drilling into the mud, the water temperature It dives into the mud and hibernates below 7°C. Loach can not only use gills to breathe, but also use skin and intestines to breathe. It has strong adaptability to the environment and strong hypoxia tolerance. It usually lives at the bottom of the water, has the habit of drilling mud, and likes neutral and slightly acidic clay soil. Field eels are omnivorous fish that often feed on daphnia, silkworms, aquatic plants, and microorganisms in the water. They are often used to breed bait by stacking chicken m...
