摘要
用400Hz正弦波连续音对不同体长鲤Cyprinus carpio进行音响驯化，探讨声音对不同体长鲤的诱集效果。结果表明：体长30—40cm和20—30cm的鲤，驯化第8d聚集率达到100％；体长10～20cm的鲤，驯化第6d聚集率达到100％；体长5～10cm的鲤，驯化第5d聚集率达到100％。平均聚集时间，体长30～40cm的鲤为50．01S，20～30cm的鲤为49．37S，10～20cm的鲤为48．77S，5～10cm的鲤为47．25s。400Hz正弦波连续音对不同体长鲤均具有明显的诱集效果，但对体长较小的鲤的聚集效果相对好于体长大的鲤。
The 400 Hz sine wave continual sound was used to stimulate common carp Cyprinus carpio with different body length to evaluate the effect of sound stimulation on aggregation of the common carp. The results showed that the common carp with body length of 30 -40 cm and 20 -30 cm had aggregation rate of 100% in 8 day sound stimulation. The aggregation rate of 100% was observed in the common carp with body length of 10 - 20 cm acclimated by sound for 6 days. There was the aggregation rate of 100% in the 5 - 10 cm common carp in 5 day sound acclimation. The average aggregation time of the common carp with body length of 30 -40 em, 20 -30 cm, 10 -20 cm, and 5 - 10 cm was found to be 50.01 s, 49.37 s, 48.77 s, and 47.25 s, respectively. The 400 Hz sine wave continual sound was observed to have significant aggregation of the common carp, more aggregation in the larger common carp than that in the smaller fish.
