Are there any senior fish farmers who share how to play with all aspects of seedling medicine?

Fry and feed are the two most important elements of Huang Guosheng's cultivation. I believe that seed is the foundation of breeding, good seed can produce high-quality breeding performance, fish physique, growth rate and weighing have a lot to do with fry. "It looks like a fish of the same size, different fish species can produce a difference of 1 tael, if it is 10,000 fish, it will be 1,000 catties, and a pond will be a few thousand catties, which is not a small amount.

Therefore, in the course of many years of breeding, I have developed the habit of tracking the fry and the nursery master's seedling technique, the seed should be good, the master's seedling technology should also be solid, and then through my own and friends' breeding tracking, and finally select the right tilapia fry.

In addition to seeds, feed is also a key part. Good feed can give seedlings a good physique. According to his own experience, the difference in feed is mainly reflected in the meat of the back of tilapia, before he used a certain brand of tilapia feed, the body grew long, but the back meat was not thick enough, the meat yield was low, and it was not on the scale.

After using the "Yihai" brand tilapia feed of Zhanjiang Yuehua Aquatic Feed of Hengxing Co., Ltd., Huang Guosheng's tilapia has changed significantly. He introduced that when feeding, tilapia fish grabbing food is more powerful, the fish growth rate is faster, and more importantly, the back meat of tilapia is very thick and shiny, and it looks very good. "After raising tilapia for so many years, I feel obviously different when I use Yihai feed.

Huang Guosheng said. Breeding is a meticulous job, and if you don't do it yourself, you don't know many details. "Huang Guosheng likes to do it himself, from feeding during the day to patrolling the pond at night, everything has to be done in person to be practical.

He feeds two meals a day, the first meal at 8-9 a.m. and the second meal at 4-6 p.m. At night, Mr. Wong became more vigilant, fearing that the lack of oxygen in the water would cause a mass mass of dead fish. Every morning at 2-3 o'clock, he will get up to patrol the pond to observe whether there are fish floating heads and the operation of the aerators, and adjust the number of aerators.

3-5 tael size tilapia is a critical stage in farming. Huang Guosheng told the reporter of "Agricultural Treasure Book" that at this time, tilapia grows faster, and it is necessary to ensure its intestinal health, so that tilapia can feed normally and grow healthily. To this end, Huang Guosheng will mix some Chinese herbs in the feed according to the weather conditions to ensure intestinal health.

As the feed began to increase at this stage, the excrement such as bait and tilapia feces also increased, the nutrients in the water accumulated rapidly, and the water quality was prone to change. In the high temperature season, in order to reduce the digestive burden of the fish, the feed should be controlled appropriately. As soon as you find that the fish is sluggish or there are other things wrong, stop the feed immediately and increase the amount of water exchange.

You can use feed and medicine to blend, and you can also mix with water, you must pay attention to the ratio, but also pay attention to the appropriate amount of taste, but also pay attention to some flavor enhancers in the feed.

Seed is the foundation of breeding, good seed can produce high-quality breeding performance, fish physique, growth rate and weighing have a great relationship with the seed. Then a good feed can give the seedlings a good physique. Breeding is a meticulous work, do not do it yourself, many details are not known, you need to do it yourself.

The feeding habits of summer flowers of the red-billed catfish change with the age of the day, and the specific changes are shown in Table 2.

Table 2 Changes in the feeding habits of summer flowers of C. chinensis with age.

According to the changing characteristics of the eating habits of the warped red catfish, in the specific production practice, the cultivation method based on soybean milk is usually adopted, the quality of soybeans and soybean cakes should be good, and the soaking time should be appropriate. Splash soybean milk evenly, try to achieve more and less times, and strive to eat the fry evenly. If the fertilization-based cultivation method is adopted, an appropriate amount of concentrate feed should be supplemented according to the growth of the fry.

Soybean milk or silkworm pupal pulp is fed at 9 a.m. every day, and the amount of feed depends on the number of zooplankton in the water.

Timing: In the past, concentrate feed was generally required to be fed twice at 8 10 a.m. and 2 4 p.m. The purpose of timing is to make the fish make reasonable use of the feed, so that the feed can achieve the best utilization effect after feeding.

In July and August, the water temperature of the pond is high, the fish grow fast, and the amount of feed is more per day, so it needs to be fed 3 or 4 times, so that the amount of feed can be fed less at one time, prolong the residence time of bait in the digestive tract, and improve the digestion and absorption of feed.

Positioning: In order to reduce the waste of feed settling at the bottom of the pond when splashing, the fish breeding pond must be set up with a food table, according to every 3000 fish fingerlings set up 1 meter 2 food table, concentrate feed should be put on the feed table. The feed table and field should be cleaned and disinfected regularly.

Qualitative: concentrate feed shall not be mildewed and deteriorated, and should be finely ground during processing, and it is best to prepare pellet feed or full price feed according to the needs of the fish body.

Quantitative: No matter what kind of feed is fed, it should be reasonably quantified according to the needs and intensity of fish feeding, not too much or too little. It is advisable to eat concentrate in 1 2 hours after each feeding.

In short, the amount of bait should be appropriate and uniform. However, it should be reduced as appropriate during rainy days and abnormal weather changes and fish disease seasons.

Out of the pond: Fish fry are cultivated to about 35 days, and when they grow to centimeters, after pulling the net for 3 times, they are ready to go out of the pond and transfer to fingerlings.
