ARIS dataset: Three fish species

Imaging Sonar data collected using ARIS Explorer 1800 sonar using 1.8 MHz frequency. The sonar data were collected in an experimental pond (width: 6.5 m, length: 46 m, depth: 0.8 m). The velocity regime of the experimental pond was slow and relatively constant (0.08 – 0.14 m/s: measured using a SonTek FlowTracker). An imaging sonar (ARIS Explorer 1800, Sound Metrics Corp.; www.soundmetrics.com) was set facing across the pond and perpendicular to the current. The transducer was mounted 0.05 m below the water surface. Three fish species were in the pond at separate times: Atlantic salmon (number of fish in the pond n=43), striped bass (n=100), and American shad (n=13).

本数据集为采用ARIS Explorer 1800声呐以1.8 MHz频率采集的成像声呐（Imaging Sonar）数据。数据采集于一处实验池塘，该池塘尺寸为宽6.5米、长46米、深0.8米。实验池塘内水流流速缓慢且相对稳定，流速范围为0.08–0.14 m/s，测量仪器为SonTek FlowTracker流速仪。本次实验使用的成像声呐为ARIS Explorer 1800（Sound Metrics公司；官网：www.soundmetrics.com），其布置方向为横跨池塘且与水流方向垂直。该声呐的换能器安装于水面下0.05米处。池塘内分阶段投放了三种鱼类：大西洋鲑鱼（池内鱼群数量n=43）、条纹鲈（n=100）以及美洲西鲱（n=13）。更多详细信息可参考https://doi.org/10.1002/tafs.10318。注意：作者可应请求提供更多原始数据，但受限于文件体积，本次公开的仅为20 GB的样本数据集。
