Acoustic communication is vital across many taxa for mating behavior, defense, and social interactions. Male oyster toadfish, Opsanus tau, produce courtship calls, or “boatwhistles,” characterized by an initial broadband segment (30–50 ms) and a longer tone-like second part (200–650 ms) during mating season. Male calls were monitored continuously with an in situ SoundTrap hydrophone that was deployed in Eel Pond, Woods Hole, Massachusetts, during the 2015 mating season. At least 10 vocalizing males were positively identified by their unique acoustic signatures. This resident population was tracked throughout the season, with several individuals tracked for extended periods of time (72 hours). Toadfish began calling in mid-May when water temperature reached 14.6 °C with these early-season “precursor” boatwhistles that were shorter in duration and contained less distinct tonal segments compared to calls later in the season. The resident toadfish stopped calling in mid-August, when water temperature was about 25.5 °C. The pulse repetition rate of the tonal part of the call was significantly related to ambient water temperature during both short-term (hourly) and long-term (weekly) monitoring. This was the first study to monitor individuals in the same population of oyster toadfish in situ continuously throughout the mating season.

牡蛎蟾鱼的季节性和日常交配模式，Opsanus tau

对于交配行为、防御和社会互动，声学交流对于许多分类群至关重要。雄性牡蛎蟾鱼 (Opsanus tau) 会发出求偶叫声或“船笛”，其特征是在交配季节的初始宽带段 (30-50 毫秒) 和更长的类似音调的第二部分 (200-650 毫秒)。在 2015 年交配季节，部署在马萨诸塞州伍兹霍尔的鳗鱼池的原位 SoundTrap 水听器持续监测雄性的叫声。至少有 10 只发声的雄性通过其独特的声学特征得到了肯定。整个季节都对这些常住人口进行了跟踪，对几个人进行了长时间（72 小时）的跟踪。蟾鱼在 5 月中旬水温达到 14 度时开始鸣叫。6 °C 与这些季节早期的“先驱”船笛声相比，与季节后期的叫声相比，持续时间更短且包含更少明显的音调片段。八月中旬，当水温约为 25.5°C 时，栖息的蟾鱼停止鸣叫。在短期（每小时）和长期（每周）监测期间，呼叫音调部分的脉冲重复率与环境水温显着相关。这是第一项在整个交配季节连续原位监测同一种群牡蛎蟾鱼个体的研究。在短期（每小时）和长期（每周）监测期间，呼叫音调部分的脉冲重复率与环境水温显着相关。这是第一项在整个交配季节连续原位监测同一种群牡蛎蟾鱼个体的研究。在短期（每小时）和长期（每周）监测期间，呼叫音调部分的脉冲重复率与环境水温显着相关。这是第一项在整个交配季节连续原位监测同一种群牡蛎蟾鱼个体的研究。
