温度、盐度和pH值对疣荔枝螺耗氧率的影响

Influences of temperature, salinity and pH value on oxygen consumption rate of Thais clavigera

以疣荔枝螺(Thais clavigera)为材料,用碘量法测定温度、盐度及pH变化对疣荔枝螺耗氧率的影响.结果表明:温度、盐度及pH值对疣荔枝螺的耗氧率有明显影响.在13~28 ℃范围内,疣荔枝螺的耗氧率随温度的升高而增大,但当温度达到32 ℃时,耗氧率反而下降.疣荔枝螺的耗氧率在自然盐度和pH值时均最大,随着偏离自然盐度(28 ℃)和自然pH值(7.5)的逐渐增大,其耗氧率均逐渐下降.水利论文b8_`P6P3gJ }
