Attention:
Please note that operations of the Fishnet Echo Sounders requires experienced scientific staff on board and can only be operated upon request. The system is not operated by the ship's crew. Request operations with the Fishnet Echo Sounders to AWI-Logistics in sufficient time prior to the cruise and clarify the data transfer after the cruise.
Summary
The net echo sounders are used for information about the status of fishnets deployed in the water. Information about depth of the net, distance to seabed and amount of fish coming in are provided. Small sensors are attached to the trawl and deliver data to the ship where they are received by hydrophones. The SCANBAS365 system can be used together with the SS4 catch sensor, the SS4 door sensor and the TE40 trawl eye available on RV Heincke.
