In order to clarify cardiac arrest and restart mechanisms during gamete release in salmon, carbocyanine fluorescent dyes (DiI) was used to observe electrical conduction system of the chum salmon heart. It was found that the vagus nerve (parasympathetic nervous) was innervated from the visceral branch to the cardiac branch. During sperm release of male rainbow trout, which is a multiple spawner species, the ventricular fibrillation was recorded by electrocardiogram data-logger suggesting that the cardiac arrest occur not only semelparous species but also polytelic species. The cardiac arrest during gamete release in salmon was considered to the similar phenomena of the vasovagal response in human being that was caused by strong pain stimulating the vasomotor center in the brain via the afferent branch of the vagus nerve, and then decreased the heart rate.

为了阐明大马哈鱼配子释放过程中心脏骤停和重启的机制，采用碳氰荧光染料（DiI）对大马哈鱼心脏电传导系统进行了观察。发现迷走神经（副交感神经）受内脏支至心脏支的支配。虹鳟鱼是一种多产卵鱼类，在雄性虹鳟鱼的精子释放过程中，通过心电图记录仪记录到心室颤动，提示心脏骤停不仅发生在半产卵种类，也发生在多产卵种类。鲑鱼释放配子时的心脏骤停被认为是类似于人类血管迷走神经反应的现象，即强烈的疼痛通过迷走神经传入支刺激大脑的血管舒缩中枢，从而使心率降低。
