Male olfactory cues may guide aggregation on spawning reefs, mate evaluation, and synchronized gamete release in lake trout Salvelinus namaycush, but a lack of information on the source and identity of the cues precludes direct tests of their function. Using a two-channel flume, we found ovulated female lake trout increased time spent in the channel treated with spermiated male-conditioned water, urine, and bile but not synthesized prostaglandin F2α . We suggest future efforts to characterize male olfactory cues focus on urine and postulate that bile acids contribute to its behavioural activity. This article is protected by copyright.

雌性湖鳟 Salvelinus namaycush 对雄性化学刺激和前列腺素 F 2α 的行为反应

雄性嗅觉线索可能会指导湖鳟 Salvelinus namaycush 的产卵礁聚集、配偶评估和同步配子释放，但缺乏关于线索来源和身份的信息，无法对其功能进行直接测试。使用双通道水槽，我们发现排卵的雌性湖鳟鱼在用精子处理的雄性条件水、尿液和胆汁处理的通道中花费的时间增加，但未合成前列腺素 F2α。我们建议未来将男性嗅觉线索的特征集中在尿液上，并假设胆汁酸有助于其行为活动。本文受版权保护。版权所有。
