Feeding the whole material not only makes the fish grow faster, but it can also get a good price early.

“Last year, I spent a total of 6,000 yuan on a total of 30 acres of fish ponds, and one fish had no disease.” Huang Huaijin, a tilapia farmer in Maling, Xiaojinkou Town, Huizhou, told reporters. Compared to some farmers around it, they spent more than 10,000 yuan to buy fishery medicines. Not only did they spend more money, but they also suffered from fish. Huang Huaijin was very grateful for his choice. In addition, due to the full feed, the long-term speed of farmed fish is fast, not only the main tilapia production is high, and the benefits are good. The polyculture of freshwater whitefish and grass carp also gain good short-term economic benefits.

It is understood that in Xiaojinkou and even Huizhou as a whole, most tilapia farmers are from the village of Zhejiang Jinyun. They use a three-dimensional breeding model of fish-duck breeding. They started seedlings at the beginning of the year and the Qing pond at the end of the year. Huang Huaijin is one of them.

Feeding tilapia through the whole feeding process “In the surrounding area, there are not many feeds like me.” Huang Huaijin introduced that most farmers are all feeding pre-all duck dung and only feed some of them at a later stage. Few breeders have started feeding their feed. "I am worried that the cost of feeding the whole process is high. In fact, it is not very high. In addition to the other polyculture varieties, the feed cost is about 2.3 yuan/kg." Huang Huaijin said.

Huang Huaijin introduced that the last fish was cast after Qingming last year. The fry was about 3cm in size, with a density of 1300-1400 tails/mu, and the fish was fed with submerged materials. In the lunar month of June, tilapia specifications reached 2.5 two-tails. At this time, selling nearly 20,000 pounds of fish such as the big head, white plague and freshwater pelicans in the fish ponds began to raise tilapia. Since selling fish freed up space for 10,000 kilos of fish, it began to increase the amount of feed, feeding it in accordance with the amount of 100 kg of fish fed with 3 kg of feed, and the amount of feed at the peak reached 5 packets per day. In just two months, the size of the fish body increased from 2.5 to 2.5 pounds per tail.

Huang Huaijin pulled the fish out of the net for the first time last year on September 15th of the Lunar Calendar. “Only a pond corner has 14,000 kilograms, and 1 kilogram and half account for more than 60%.” He told reporters that the lunar calendar had pulled back in early October. Once on the net, until the end of the lunar calendar in late Qing Dynasty, the total fish was 32,000 kilos in three rounds, with an average size of 1.7-1.8 pounds per tail.

The polyculture of other breeds has different benefits compared to the high-density pure-cultivation model. The polyculture model is to make full use of space such as land and water to maximize the benefits. However, Huang Huaijin believes that since it is the main culture of tilapia, other species serve tilapia.

In the polyculture model of fish and ducklings, there are not many ducks raised by Huang Huai, and only 2,500 ducks are raised on 30 mu of water. “The main reason for raising ducks is to use fertilizer.” When the semi-digested duck dung is used in the pond for secondary use, it provides planktonic algae and other biological feeds for the tilapia in the water, which promotes the growth of the fish.

At the same time, Huang Huaijin also made full use of the water space and mixed other varieties of fish. There were 4,200 freshwater whitefish, 1,000 silver carp, and 2000 silver carp that were released before the Qingming period. In the Lunar Calendar, 2000 fish grasses were released in June.

Different from others, Huang Huaijin’s freshwater white plover is a seedling with a specification of only 200 tails/kg, and is fully fed. From the time of the investment, the fish can be sold after 3 months, and the specifications can be up to 1.3 pounds/tail. According to its introduction, the surrounding farmers have all released about 4 freshwater whitefish fry in the same period. However, because they only feed ducks, the growth rate is slow. It is difficult to achieve the same specifications for three months of feeding.

As the tilapia feed was fed throughout, the speed of other fish was also accelerated, and most of the lunar calendar had reached the specifications by the end of June and could be sold. Huang Huaijin believes that the short-term profits of freshwater whitefish and grass carp in the polyculture pool are relatively high. “At the end of June of the lunar calendar, I will sell all of the freshwater whitefish, big heads, and grass carp in the pond, nearly 20,000 pounds.” , On the one hand, the fish can be used to feed on the feed for tilapia cultivation; on the other hand, the corresponding water space can be released for the growth of tilapia. At this time, the feed amount of tilapia can be increased and the tilapia can be accelerated. The growth.

Paying attention to water quality management Huang Huaijin also knows the truth of “fish farming and water conservation”. In particular, in recent years, the disease of tilapia has been serious every year. It is also focusing on daily water quality regulation and disease prevention.

In the hot season of hot diseases, Huang will kill insects and disinfect first, and then use Bacillus, Motherwort, etc. to transfer water. "After the lunar calendar June, when tilapia is raised purely, water is transferred almost once a month." Huang Huaijin told reporters that last year a total of four transfers of water had not only no dead fish, but only 6,000 yuan for water transfer.

In addition, Huang Huaijin's years of breeding experience has concluded that before and after the sale of fish on the pull-net, it is also necessary to pay attention to the key moments of water quality management. "Last year, tilapia was not done well before pulling the net for the first time. A few hundred pounds of fish died within a few days after pulling the net." Huang Huaijin recalled that he was still sorry. With the first lesson, the water bodies were first sterilized and then some anti-stress drugs were spilled before the nets were pulled twice. This not only regulates the water quality, but also enhances the anti-stress ability of the fish and ensures the fish. Not damaged.

Although Tilapia Huang Huaijin has already established a set of models, he still told reporters that "Last year's profits were not high and we still continue to explore and need continuous improvement to find the highest profits."
