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).
