The face of scientist: The female doctor 'dolphin'

After many contacts, she agreed to receive a journalist at the Vietnam - Russia Tropical Center (Ministry of Defense). Unexpectedly, she, a high ranking army officer, was much nicer than her age. She is the female scientist - Dr. Nguyen Thi Nga, deputy director of the southern branch of Vietnam - Russia Tropical Center, who gives farmers more options to trade golden triploid catfish. , using biochemical technology to treat seawater cleaning in Suoi Tien Tourist Area. And recently, she was named "Vietnamese female dolphin doctor ".

Wading pond ' to life ' yellow catfish

Dr. Nguyen Thi Nga

She said that normal fish have a double diploid chromosome (2n), if taken with thermal shock (a technique of biotechnology), there will be a triploid chromosome (3n). Triploid fish will have vitality, greater speed than diploid fish. Currently, in the market are commonly adopted three varieties of yellow catfish, on the ground, in the future. The advantage of these three varieties is that there is a short breeding cycle, the fish suffer from omnivorous feeding, so they are also " burdened " by some food sources, and the quality of the meat is quite good. But these three varieties also have limitations such as slow growth, high resistance to disease. The triploid yellow catfish, besides the advantages such as the three above mentioned catfish varieties, also avoid the limitations that these three breeds suffer .

The common mechanism for "giving life " to yellow catfish, it is not easy to hear. It took nearly three years, the " life " plan of gold catfish was completed. She recalled: "For nearly three years, the research team went out to the laboratory again . to wade the pond, to study and experiment with the nursery. When it was successful, it was to study the secret again. In order to stabilize the seed production process, then when the golden catfish has been released to the pond, it will continue to monitor their living process.

She said that, in the same culture conditions, the time of raising (4 months) yellow catfish usually harvested 27.66 tons / hectare, while the triploid yellow catfish was 34.01 tons / hectare. It is calculated that the productivity of golden triploid catfish is 7.35 tons / ha higher than the yellow catfish (about 21.61%). In terms of quality and taste of meat, in terms of sensory perspective, both common yellow catfish and triploid yellow catfish are the same. However, in terms of "weighing, measuring, measuring", the meat of triploid yellow catfish has lipid content, essential amino acids (except methionine), essential fatty acid . higher than fish. on normal gold.

Farmers - who directly raised the new researched fish - concluded that the golden trout catfish were "better" than regular yellow catfish. After 4 months of experimenting on the triploid catfish, Mr. Tran Viet Huy, in Long Duc commune, Long Thanh district, Dong Nai province, gave a brief comment: positive! Taking out one kilogram of gold trout, he sold from VND 16,000 to VND 18,000, while yellow catfish usually only sold VND 9,000 - VND 10,000.

Dr. Russia and Russian experts are tending dolphins.

Mr. Huy also said that compared to regular yellow catfish, triploid yellow catfish grew faster, less sick ., and "suggested some scientific brothers and sisters in Vietnam - Russia continue to provide I look like this golden catfish ". Not only Mr. Huy, but also other farmers in District 12, District 9, Thu Duc District . after initially experimenting, they also want to continue to invest in expanding the breeding of Golden Trout Catfish. Russian!

Out to sea for dolphins

In 1976 graduating from university of biology, Nga went on to master's degree and then taught at Hanoi Pedagogical University 2. From 1985 to 1989, she worked as a doctoral student and obtained a doctorate at the Korean Institute. Forest Science of Russia, then returned to work at the Vietnam - Russia Tropical Center.

From 1990 up to now, she has spent a lot of time and effort to study dolphins, once participated in catching dolphins in the East Vietnam Sea on domestication, adapting them in conditions of farming. Her topic was excellently evaluated by the Department of Science and Technology of Ho Chi Minh City and accepted by the Council to upgrade and implement state-level applied research. The domestication and training of Vietnamese dolphins by Russian doctor has opened a new possibility: Vietnamese people can now lure, train, nurture and educate dolphins . circus performances.

She said that first, the job pushed her to the dolphins, but then the dolphins were . mesmerizing her. She was passionate about the example of a dolphin catch in May 2002: "Dolphins have a good liking for fun. We let the ship race, play with them. When they were excited to come out of the water, it was tumbling. we tucked our tail and caught it. Because dolphins are so sensitive, my partners have to jump into the sea to embrace and talk to them . ".

A farm of catfish in gold

In that session, there were a total of 8 dolphins, but after choosing, the experts only caught one child to tame - train. It is easy to hear, but the work is not simple. As the project leader, she and her Russian and Vietnamese colleagues spent 5 months with more than a dozen floating trips on the coast of Kien Giang. Previously, they had spent a year and a half to survey the Binh Thuan sea but had no results. The success of capturing, domesticating - training dolphins in Vietnam for the first time is what makes the scientific community extremely excited.

Vietnamese experts, with the support of Russian experts, have been floating on the sea for 300 days to survey dolphins in some waters of Vietnam. Work is extremely difficult and hard. It was not until the beginning of 2003 that the survey team captured a pair of one-male dolphins, one at Kien Giang sea. However, during the transportation process, the experts found that the children were not sure, so they decided to drop the sea. And the male was transferred to the store, domestically adapted in rafts in the island of Kien Giang.

She said that the classification results based on morphology have identified this as Tursiops aduncus dolphin and named " Hero " (He is the name of a young researcher in the Vietnam - Russia Tropical Center and Hung is the name of the captain who helps the group to catch fish. " Hero " weighs 110kg, is 1.95m long and is about two and a half years old. Experts judged that the dolphin is very smart and emotional, friendly, especially adapted very quickly.

Ms. Nga confided: "But, no matter what I do, I always guide myself and improve myself, always learn and have to do well the work of my wife and mother. As a woman . "Women" are loved by everyone, Glorious to the extent that their children are not good, their families are not good, it is very miserable that the commune knows his work well, his two children are good at school. all have graduated from university and are studying at doctoral level, optimism and love of life in all situations are not only the virtues of people who do science but also the quality of women in life ".
