Detailed Description

The following is a description of the preferred embodiments of the present invention, and it should be understood that the preferred embodiments described herein are merely illustrative and explanatory of the invention, and are not restrictive thereof.

In addition, if a detailed description of the known art is not necessary to show the features of the present invention, it is omitted.

Example 1

The invention provides an oxygen-increasing feeding method for prawn culture, which comprises the following steps:

1. firstly, the medicine which can kill or inhibit protozoa is splashed in a whole pool, and a mixture of copper sulfate and ferrous sulfate (5:2) is recommended to be used, wherein the concentration is 1 ppm;

2. spraying oxygen increasing agent (such as calcium peroxide, 3ppm for the first time, and increasing the amount and frequency of application depending on prawn condition) one hour later, wherein the powder and water can be used alone;

3. adding fresh water in a proper amount, wherein the total water content is about 20 percent generally, if the water quality (harmful substances such as ammonia nitrogen and the like exceed standards), water can be changed, and the water is usually 1/4-1/3 of the total water according to the situation;

4. on the day or the next day, the rich aquatic product is used for culturing algae, and 3ppm of nitrogen fertilizer and 0.5ppm of phosphate fertilizer are recommended to be used, and a proper amount of organic fertilizer (chicken manure, soybean meal, rice bran and the like containing probiotics) is added;

5. calcium and microbial agents are supplemented appropriately. The calcium product is mainly calcium chloride with the concentration of 5ppm, and the microbial preparation recommends using EM bacteria or photosynthetic bacteria with the concentration of 5-10 ppm; bacillus is recommended for middle and late stage prawn, and the concentration is 2-5 ppm.

The above steps can be completed within one or two days.

Such conditions are water quality algae (oxygen producers are absent), protozoa multiply (dead algae provide large amounts of food) and become the main oxygen consumers in the water, and protozoa must be killed or inhibited to enable various oxygenation measures to work.

The feeding step comprises the following steps:

like the oxygenation device of the small stool, the tube is made into the stool, but is longer, the length is 5-10 meters, the width is one meter, the height is about forty centimeters, the stool surface is a left and right 80-mesh net, sand is filled in the tube, the purpose is to make the stool sink and place around the pond, because shrimps basically feed at the peripheral edge of the pond, the feeding is just fed on the stool at ordinary times, the advantage of doing so is that the shrimps do not need to go mud and eat, the fodder can not pollute, and can wash; moreover, the shrimps can inhabit on the feeding platform at ordinary times without contacting bottom sludge, so that the risk of germ infection is reduced.

In addition, an improved version is tested, namely the pipe is changed into a micro-filtration pipe which is also an oxygen increasing pipe and is connected with an air pump, and two methods are also tested, namely the brick is bound, and the steel wire is threaded into the pipe and fixed at the bottom of the pond.

The invention kills or inhibits protozoa, reduces main oxygen consumption in water, uses aquatic products to cultivate algae to form oxygen, and adopts the method of oxygen increasing agent to increase oxygen, thereby ensuring oxygen supply for prawns, ensuring that the prawns can eat without mud removal and craving, preventing feed pollution, cleaning and reducing the risk of germ infection without contacting bottom mud.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
