Globally, interactions between fishing activities and dolphins are cause for concern due to their negative effects on both mammals and fishermen. The recording of acoustic emissions could aid in detecting the presence of dolphins in close proximity to fishing gear, elucidating their behavior, and guiding potential management measures designed to limit this harmful phenomenon. This data descriptor presents a dataset of acoustic recordings (WAV files) collected during interactions between common bottlenose dolphins (Tursiops truncatus) and fishing activities in the Adriatic Sea. This dataset is distinguished by the high complexity of its repertoire, which includes various different typologies of dolphin emission. Specifically, a group of free-ranging dolphins was found to emit frequency-modulated whistles, echolocation clicks, and burst pulse signals, including feeding buzzes. An analysis of signal quality based on the signal-to-noise ratio was conducted to validate the dataset. The signal digital files and corresponding features make this dataset suitable for studying dolphin behavior in order to gain a deeper understanding of their communication and interaction with fishing gear (trawl).
全球范围内，渔业活动与海豚之间的相互作用引起了人们的关注，因为这些相互作用对哺乳动物和渔民都有负面影响。记录声学排放物可以帮助检测到海豚在靠近渔具的地方的存在，阐明它们的行为，并指导旨在限制这种有害现象的潜在管理措施。本数据描述符提供了一个在亚得里亚海，在常见宽吻海豚（Tursiops truncatus）与渔业活动相互作用期间收集的声学记录（WAV 文件）数据集。该数据集的特点是其曲目具有很高的复杂性，其中包括各种不同类型的海豚发射。具体来说，发现一群自由游动的海豚发出调频口哨、回声定位点击和爆发脉冲信号，包括觅食嗡嗡声。根据信噪比进行了信号质量分析，以验证数据集。信号数字文件和相应的特征使该数据集适合于研究海豚的行为，以便更深入地了解它们与渔具（拖网）的通信和相互作用。
