温度对宽体金线蛭生长的影响
Effect of Water Temperature on Growth of Leech (Whitmania pigra)
摘要
Abstract
[Objective] The paper aimed to study effects of different water temperature on growth of leech (Whitmania pigra) and provide a scientific basis for breed culture. [Method] The experiment animals were divided into 4 groups at random, and bred in 20 days under different temperature conditions (15,20,25,30 ℃), weighted interval 2 days, the average daily gains of leech in each groups were compared. [Result] Average daily weight increased 2.04%,2.99%,3.23%,0.62% under the 15, 20, 25,30 ℃. When the temperature raise from 15 ℃ to 20 ℃, the growth of leech increased became faster (P<0.05). Rates of average daily gain of leech became highest when achieved 2.99%-3.23% under range of 20-25 ℃,no significant difference (P>0.05). When the temperature was higher than 30 ℃, the growth and the livability of the leech significantly reduced(P<0.05), survive rate was 55%. [Conclusion] The range of the optimal temperatures for leech growth is from 20 ℃ to 25 ℃.关键词
