| 摘 要： | 在实验室饲养的条件下，研究了正颤蚓在15℃、20℃、25℃水温的生长发育和繁殖过程。结果表明正颤蚓从其受精卵在蚓茧内发育，孵出生长到产卵，在15℃水温需100—123d，在20℃水温需70—90d，在25℃水温需48—64d。蚓自蚓茧内孵出后的165d生长期内，其15℃、20℃、25℃水温的体重生长回归方程分别是W=6.87/［1+136.48

| Abstract: | The growth and reproduction of Tubifex tubifex have been studied in laboratory cultures at different water temperatures (15℃,20℃,25℃). The life cycle of T. tubifex, takes 100 to 123 days in experimental culture at 15℃,70 to 90 days at 20℃ and 48 to 64 days at 25℃. During the experimental period (165 days as maximum observed), the regression formula describing the growth of weight of animals at 15℃ is :W=6.87/［1+136.48*exp(-0.0612t)］,at 20℃: W=5.99/［1+118.8*exp(-0.0918t)］ and at 25℃: W=6.82/［1+135.28*exp(-0.1389t)］. The regression formula describing the growth of length of animals at 15℃ is: L=58.3/［1+13.58*exp(-0.0384t)］, at 20℃: L=51.3/［1+11.83*exp(-0.0566t)］ and at 25℃: L=54.4/［1+12.6*exp(-0.0872t)］. The regression formula describing the relationship between weight and length of animals at 15℃ is: W=3.1072L1.9486, at 20℃: W=2.9228L1.9781 and at 25℃: W=2.6725L1.9875. In addition, the relationship between growth of animals and water temperature was discussed. |
