The purchase of about 150 grams of young turtles is characterized by high investment efficiency and low risk. Temperature-controlled culture experiments showed that hatchlings grew slowly under 150 grams, and then the growth rate was significantly increased: the daily weight gain was 50 grams or less and the daily weight gain was 0.6 grams; 50 grams to 150 grams daily weight gain was 0.85 grams; 150 grams to 250 grams Daily gain of 1 g; 250 g or more daily gain of more than 1.5 grams. After growing to 1000 grams (female), the growth rate slows down. Moreover, hatchlings grow from 4 grams to 150 grams, and the survival rate is about 85%, while 150 grams of young turtles raise 500 grams of commercial turtles, and the survival rate can reach 98% or more. Therefore, the purchase of about 150 grams of young turtle breeding, the investment cycle is short, the risk is small, the benefits are obvious.
