Release date: 20 10-05-08

In Xincheng Formation, Sichong Village, cheung chau island, in a sparkling fish pond, four or five farmers are carefully fishing for fry ... Two cars are waiting by the fish pond, ready to transport fry to Guilin and Hezhou. At the end of spring, near the fish pond in Sichong Village, cheung chau island, fry trading scenes like this can be seen everywhere. It is reported that cheung chau island will sell 1 100 million fry this year, and the variety has increased from four or five in previous years to more than ten now. The sales scope has expanded from Wuzhou and surrounding areas to Guigang, Yulin, Guilin, Zhaoqing, Yunfu and other places in Guangdong.

Changzhou is famous for its technology of breeding freshwater fish fry.

On April 30th, the reporter went to Sichong Village, the main fry producing area in cheung chau island, and saw that many local fish farmers were busy harvesting and loading cars and motorcycles. It is understood that at present, there are about 500 fry farmers in cheung chau island * * *, mainly concentrated in Sichong Village, which has formed a considerable industry. Zhu, who just got the first fry from the fish pond this year, said that he has sold more than 200,000 fish this year and earned more than 20,000 yuan. Now he is disinfecting the fish pond with the dregs left after oil extraction from tea seeds, and preparing for the second round of culture. "Generally, five batches of fry can be cultivated every year, from 65438+February to August of the following year."

Why are Cheung Chau fry so popular? According to reports, this is mainly because Changzhou is famous for its technology of cultivating freshwater fish fry and its quality is reliable. The fry produced not only meet the needs of the city, but also are sold to other places. According to records, Cheung Chau has been breeding fry for more than 300 years. 195 1 year, Changzhou accounts for 60.9% of the total fry production in Guangxi. From 1950 to 1956, Changzhou became an important distribution center for fry in Guangxi.

Deng, an old fish farmer with many years of experience in fry breeding in Sichong Village, said that in the past, the fry were mainly grass carp, herring, silver carp and bighead carp. Now, in addition to these four species, there are four kinds of fry, namely Luo Fei, wild carp, cuttlefish carp, cuttlefish carp, pomfret and bighead carp. Big waves wash sand, and some fry varieties with bad taste are gradually ignored. The snapper, which was loved by people in the 1990s, has already been eliminated. At present, the best-selling varieties are white pomfret, fork tail and so on.

Application of new technology in fry culture

The high fry yield in Changzhou is mainly due to the fact that local fish farmers abandon traditional practices and adopt polyculture and polyculture with high density.

With the progress of aquaculture technology, the technology of cultivating high-quality fry has reached the point of perfection. In recent years, fish farmers in cheung chau island have carried out benign circular farming and mastered the prevention and treatment methods of fish diseases. With the extensive use of aerators in fish ponds, the long-standing problem of fish fry floating head death has been solved, and the fish fry yield has been greatly improved. For example, a fish farmer named Deng explored and mastered the indigenous immunization technology of grass carp. Now more than 300,000 immune fry are injected by him every year, and the survival rate of immune fry is high.

In order to solve the problem of fry overwintering, fish farmers built overwintering plastic greenhouses in fish ponds to effectively protect fry overwintering, which laid a solid foundation for fry to go on the market in advance in the next spring and won time. For example, Deng Tingjian, a fish farmer in Sichong Village, successfully bred overwintering fry for many times, and built a greenhouse of more than 300 square meters, which solved the problem of safe overwintering of pomfret fry and easily solved the problem of relying on nature to breed.

Next to the green vegetable field, there are more than ten acres of standardized seedling ponds. As soon as the fry swim in the pond, waves appear, and dense black spots jump up and down. This is the first batch of carp fry cultivated by Li Mingjun, a fish farmer in Sichong Village this year. On April 30, Li Mingjun learned by phone that several old buyers arrived as scheduled, and the opening price was not shocking: "9 cents per tail, 2 cents higher than last year." There are more than 500,000 carp fry cultivated in Li Mingjun, which were snapped up by several merchants on the same day.

At the edge of the fish pond, I saw Deng throw handfuls of feed into the pond, and the water began to make waves-koi fish, graceful and colorful, rushed up to eat, and koi fish danced like a butterfly. He said that this is his new species-long fin koi fish, and each tail is about 1.6 yuan. He said that this koi fish has a good body shape and is a new variety promoted by the state, with a bright market prospect.

Huang Rongjun, a big fish fry seller in Sichong Village, sells 3 million fish fry every year and supplies them to Hezhou aquatic products market at fixed points. ...

According to reports, the reasons for the popularity of fry this year are as follows: First, the scale of fish farming has been continuously expanded in various places, especially in river cage culture; Second, there is demand for high-quality fry, such as koi fish, pomfret and fork tail, which are often in short supply; Thirdly, the reputation of cheung chau island fry spread far and wide, attracting many farmers from other places to buy it.

At present, although there are more than 500 fry breeders in Changzhou, there is still a big supply gap, so there is a great market to accelerate the development of fry industry in cheung chau island.

Looking forward to the establishment of a fish hatchery

In the interview, the most talked about by fish farmers in cheung chau island is that they want to set up a fish hatchery in Wuzhou to solve the problem that fish farmers have to travel long distances to buy hatched fish and come back for breeding.

It is reported that the sales momentum of fry in cheung chau island is very strong. Unfortunately, there is no fish hatchery in Wuzhou. Chen, a fish farmer in Sichong Village, knows the history of fry breeding in cheung chau island like the back of his hand: the local fry hatchery in Wuzhou was originally located in Gaowang area on the south bank, but unfortunately it was destroyed by the flood of 1994 and never recovered. In recent years, fish farmers in cheung chau island have to go to Guangzhou, Jiangmen and other places in Guangdong to buy fish as big as newly hatched hair, and then breed them into fry when they come back, which invisibly increases the cost and the quality may not be guaranteed, which has become a heart disease for fish farmers.

"I hope we can restore and establish a local fish hatchery in Wuzhou to meet the needs. Only in this way can the recovery of cheung chau island fry industry distribution center be just around the corner. " Fish farmer Deng said earnestly. (
