Abstract：In order to promote water-saving aquaculture, the effects of three aquaculture water levels on the growth of 2-year-old Asian yellow pond turtle Mauremys mutica were investigated. One turtle was reared in a box (16.9 cm×10.5 cm×7.4 cm), 30 animals in each water level group including 1 control group and 2 test groups, which were 350 mL (high water level), 260 mL (medium water level), and 110 mL (low water level). Under the same conditions of feeding and management, the growth index and morphological characteristics were measured after 7 months at water temperature of 20.7—30.1 ℃. The results showed that the body weight was significantly higher in turtle in the middle and high water levels than that in the low water level (P<0.05). Turtle carapace length, carapace height, plastron length and carapace bridge length were significantly higher in the high and middle water levels than those in the low water level at the later stage of the test (P<0.05). The final carapace width of the turtles was significantly lower in the high water level test group than that in the low water level test group (P<0.05). The flatness of the middle and high water level groups was shown to be significantly lower than that in the low water level group (P<0.05). In this article, low water level significantly affected the weight, traits and body shape of the tested turtles, while the medium water level did not significantly affect the weight, traits and body shape of the tested turtles. It can be seen that the low water level significantly affects the body weight, morphological characteristics and flatness index of the tested turtles. The low water level group can macroscopically showed the adjustment mechanism of the turtle′s body growth in the absence of water, which had a significant water-saving effect. The mid-water level group was considered to be both water-saving efficiency and growth advantages. There was only significant growth advantages in high water level group. After comprehensive consideration of perspective of growth performance and water saving efficiency, it is concluded that the middle water level is suitable for water-saving aquaculture of the Asian yellow pond turtle.
