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

preparation example Construction

[0023] The preparation method of described nano sustained-release carrier is:

[0024] (1) The silicon hydroxyapatite, attapulgite, hydrotalcite, montmorillonite, titanium dioxide, calcite, kaolin according to 35-45: 10-15: 10-15: 8-10: 8-10: 7-8 : 5-7 parts by mass are mixed, added to a mixed solution of 230 parts of dimethyl sulfoxide (DMSO) and 50 parts of methanol, stirred at 65°C for 60 hours, filtered, and washed with hot ethanol at a temperature of 60°C for 3 Remove excess dimethyl sulfoxide (DMSO) once, put it into a vacuum drying oven, dry at 60°C for 24 hours, grind and sieve to obtain a primary modified compound;

[0025] (2) Mix 1 part of primary modified compound, 15 parts of potassium acetate and 25 parts of distilled water, stir at 50°C for more than 10 hours, and disperse at 30°C for 3.5 hours under the condition of ultrasonic electric power 350W, and then in Disperse for 4 hours under the condition of ultrasonic electric power 250W. Filter, wash with distill...

Embodiment 2

[0029] The preparation method is the same as in Example 1.

[0030] 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 by Beijing Century Ames Biotechnology Co., Ltd.), the other pond does not put eel fertilizer (control 2), but puts the same amount of ordinary fish food, and the rest of the feeding amount is the same, and the cultivation environment is the same. After 2-4 months of breeding, comparing its output and the growth status of rice field eels, adding the compound microbial fertilizer of the present invention can promote the rapid growth of rice field eels, increase the EPA content, reduce the diseases of rice field eels, and reduce the number of sick and dead shrimps. Beneficia...

Abstract

The invention discloses a method for breeding finless eel by nano feeds. The method comprises the following steps: selecting a pond which is in east and west directions, has a length-to-width ratio of 3 to 2, an area of 2000-10000m<2>, a pond ridge height of 1.8-2.0m and a stable water level of 1.4-1.5m, and is provided with perfect water drainage facilities as a breeding pond; disinfecting the pond in 10-15 days before finless eel fries are put into the pond, draining off water in the pond, checking whether holes are formed, cleaning the pond by unslaked lime, and feeding the finless eel fries with multifunctional microorganism feeds. Through comparison, and by adding a compound microorganism fertilizer, the finless eel can be promoted to grow quickly, the EPA (eicosapentaenoic acid) content can be increased, the finless eel diseases are reduced, the fatality rate is reduced, meanwhile beneficial microorganisms in a water body are added, and the final quality is improved.

Description

technical field [0001] The invention relates to an aquaculture method, in particular to a method for cultivating rice field eels by using nano 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 manure, cow manure, a...
