Several sounds are produced by minnows. Only one is not of purely mechanical origin, and it is classed as a "biological" sound. This sound is variously produced by males when fighting and chasing as well as during courtship. Females emit a similar sound. Testosterone injections and elevated temperatures result in an increased rate of biological sound emission.
几种声音由小鱼产生。只有一种不是纯粹的机械起源,它被归类为“生物”声音。这种声音在雄性争斗、追逐和求偶时都会发出。雌性也会发出类似的声音。睾酮注射和高温会导致生物声音发射率增加。
