The aim of the survey was to assess the relationship between the ropes at the mussel farm and pelagic fish. CTD and opportunistic video data was collected at the same time.

Data was collected at 38 and 120 kHz to assess the relationship between the ropes of the mussel farm and pelagic fish. Both frequencies collected wideband data with a slow ramp and a pulse length of 1.024 ms. Power was set to 300 W and a 1000 ms interval between pings.
