摘要
结合投饵用声音驯化鲫 (CarassiusauratusLinnaeus)幼鱼 ,结果表明鲫幼鱼对40 0Hz正弦波连续音反应敏感。音响驯化 5d后 ,鱼群在放声的同时迅速游向声源 ,在声源区密集并做回旋状游动 ;鱼群在 36～ 60s时间内聚集率达 90 %以上 ,这表明投饵前声音刺激不宜过长 ,30～
The behaviors of \%Carassius auratus\% Linnaeus juvenile were studied by means of sound taming with baiting. It was found that the fish were sensitive to sound of 400 Hz after 5 days taming. The fish ran toward the source of sound quickly as the sound rang and then swam around the source. It took about 36 to 60 seconds for the fish coming together. It shows that before giving bait the sound stimulating should not be too long.
