A digital insight into the benthic impact of salmon farms 
US Source: The Fish Site 8/8/2022

Experts in underwater imaging technology are trialling the use of 3D digital models to map out and monitor complex marine environments and habitats close to Scottish salmon farms.
Led by Oban-based Tritonia Scientific – with support from the Lyell Centre at Heriot-Watt University, salmon producer Mowi, and the Sustainable Aquaculture Innovation Centre (SAIC) – the company is testing the effectiveness of using remotely operated vehicles (ROVs) to create digital twins of the seabed.
 

Over the next 12 months, the team at Tritonia, building on existing environmental data sets, will develop a digital record of the hard substrate found near selected Mowi sites, using a technique known as georeferenced photogrammetry. Compared to soft seabed, where samples of sediment can be taken regularly and easily, monitoring hard substrates can be challenging because of the low visibility of the water even when using divers or drop-down cameras to assess the terrain. The hard nature of the seabed makes it near impossible to grab samples.
