Data from: Multi-beam sonars for monitoring the distribution and welfare of fish reared in sea cages - strengths and challenges

This dataset contains the data of the 3D distribution of Atlantic salmon in a commercial aquaculture sea cage in Norway monitored by a multi-beam sonar, at 45 different time points. The data is in MATLAB Figure (.fig) format. For more details of the data, readers are referred to the open-access article titled "Multi-beam sonars for monitoring the distribution and welfare of fish reared in sea cages - strengths and challenges" which has been published in Aquaculture journal. The article can be downloaded at the following link: https://doi.org/10.1016/j.aquaculture.2025.742553. The file names show the date and time when the data was created (when the distribution of salmon was captured by the multi-beam sonar) (YYYYMMDD_HHMMSS_3D.fig).

本数据集收录了经多波束声呐（multi-beam sonar）监测得到的挪威某商业养殖海笼内大西洋鲑鱼的三维分布数据，共计45个不同时间节点的采样内容。数据以MATLAB图形（.fig）格式存储。如需了解该数据的更多细节，读者可参阅发表于《Aquaculture》期刊的开放获取论文《多波束声呐用于海笼养殖鱼类分布与福利监测——优势与挑战》（Multi-beam sonars for monitoring the distribution and welfare of fish reared in sea cages - strengths and challenges），该论文可通过以下链接下载：https://doi.org/10.1016/j.aquaculture.2025.742553。文件名标注了数据采集时刻（即多波束声呐捕获大西洋鲑鱼分布信息的时刻）的日期与时间，命名格式为YYYYMMDD_HHMMSS_3D.fig。
