THE GROWTH OF TURTLE(TRIONYX SINENSIS)UNDER ARTIFICIAL FEEDING CONDITION

The temperature controlled at 25--30℃ is suitable condition for tur-tle growth. The period of growth form juvenile turtle (4.2--4.5g of body weight)to adult turtle (308.40--342.30g of body weight)need for 365--414 days. The survi-val rate is 80.66--87.5%. Population yield of turtle obtained 141.2--198.5kg in66.7m~2 pond. The young turtle body weight is under 50g and the daily gain is veryslow, while the body weight is over 50g, it grows fast. Under the same feeding co-ndition and of same batch of juvenile turtles, the individual growth rate is differe-nt. The sex ratio is approximtely 1:1. Under artificial feeding condition, the maleturtle grows faster than that of the female.
