In the laboratory of the College of Biological and Food Engineering of Changshu Institute of Technology, there is such a rare prehistoric creature: the translucent "small shrimp" sticks out a lot of tentacles, and in the water "backstroke" posture "follow the flow", the elegant form makes people look The child understood the meaning of the name "fairy shrimp".
However, "fairy shrimp" is not a shrimp, but an aquatic zooplankton under the arthropod. Because its parallel appearance is indeed a bit like shrimp, the color is also quite beautiful, and the water posture is also like "Flying Fairy", so it is called "Fairy Shrimp".
"'Fairy Shrimp' is not for human consumption, but mainly as an 'open feed' for aquaculture." The school's sophomore Yang Yiwen explained that this aquatic zooplankton can be eaten by the farmed fry. Improve the survival rate and quality of fry.
The ancient creature "Fairy Shrimp", which was contemporaneous with dinosaurs, has survived for 200 million years in nature. Due to its short life cycle, strong seasonality, and high requirements for living environment, "fairy shrimp" is rare in the wild natural environment. There are not many related academic researches in China, and artificial breeding is in the blank. status.
Recently, Changshu Institute of Technology has successfully realized the artificial breeding of this ancient aquatic organism.
"In the field surgery, I accidentally discovered the 'fairy shrimp' and began to pay more attention to the research. But there are very few wild animals, and later I read the media reports. As long as I found the 'fairy shrimp', I will collect the specimen." Changshu Institute of Technology Han Xiaolei, the instructor of the Aquaculture Association, said: "We used different environments to stimulate, stimulate the hatching of shrimp eggs, and went wrong thousands of times. When we almost gave up, we found the right direction."
Each organism can survive and reproduce in the natural environment with its inevitability and special "skills", while the special features of "fairy shrimp" are concentrated in the shrimp eggs.
"Fairy Shrimp" eggs can withstand long-term high-temperature baking and freezing soil test, and can still survive in boiling water, so it has a strong vitality, and can sleep for tens of millions of years, once the right conditions are met, A new life is available, which is a miracle in the biological world. It is also because of this magical "skill" that "fairy shrimp" can be proliferated for 200 million years, but although the shrimp eggs have strong viability, their hatching characteristics are extremely complicated.
"At present, we have mastered the relevant characteristics of its biomolecules and realized artificial hatching." Han Xiaolei took out a test tube filled with shrimp eggs, this dried shrimp eggs will not die, can be stored at room temperature for a long time, very convenient for transportation. It is very beneficial for later farming.
At present, the team has successfully completed the high-density culture pilot test of “Fairy Shrimpâ€, and harvested nearly a hundred tails of “Fairy Shrimp†in different periods and a considerable number of shrimp eggs. The river network in southern Jiangsu is densely populated, with a lot of fresh water resources and a large number of aquaculture. As a kind of open bait, “Fairy Shrimp†will have considerable and mature market demand prospects. (Correspondent Wang Ren)
