Freshwater crayfish farming
Freshwater lobster, originally native to the United States, was introduced to Japan during World War II and later brought to China. Today, it is widely found in the middle and lower reaches of the Yangtze River. This tropical freshwater shrimp is known for its strong adaptability, high reproductive rate, omnivorous diet, rapid growth, disease resistance, and tolerance to high temperatures. It can survive in low-oxygen environments for several hours, making it a hardy species for aquaculture.
The shrimp is not only tender and delicious but also highly nutritious, containing eight essential amino acids for the human body and low fat content. It is rich in tropomyosin and paramyosin, which enhance its edibility and make it a popular choice among consumers. With growing domestic demand and increasing export volumes, the market price has been on the rise, making freshwater lobster farming a promising and profitable industry.
Shanghai Tengxing Aquatic Technology Co., Ltd., in collaboration with the Chinese Academy of Fishery Sciences and the East China Sea Fisheries Research Institute, has developed the "Jingjia No. 3" strain of freshwater lobster. This improved variety addresses previous issues such as aggressive behavior, low breeding rates, and excessive burrowing. The new strain offers the following advantages:
1. Gentle temperament
2. High egg production
3. Fast growth rate
4. Larger body size
5. High yield and efficiency
6. Strong resistance to both low and high temperatures
7. Wide adaptability to water salinity and pH levels, allowing cultivation across all regions of China
With these enhanced traits, the "Jingjia No. 3" freshwater lobster is becoming a preferred choice for farmers and consumers alike, paving the way for sustainable and profitable aquaculture development.
