DEEP VISION HARVEST CONTROL

  • Catch more valuable fish

  • Release bycatch and undersized fish

  • Fish more efficiently and sustainably

  • Become more profitable

For more efficient and sustainable fishing

Deep Vision is an advanced subsea vision system that identifies and measures fish underwater in realtime. A Deep Vision subsea camera attached to the trawl makes it possible to identify and measure fish for the first time without bringing the catch onboard. Marine researchers have already found Deep Vision invaluable and the unique system will be launched to the commercial fishing industry in 2024. 

During a haul, fish and organisms passing through the trawl are photographed by the stereo camera. Using Deep Vision software, species are registered and lengths are measured automatically. Furthermore, images are logged with depth and time information.

The figure below shows how GPS and echosounder data can be used to locate fish along a haul relative to the water column.

Key Functionality

Be informed in realtime of type and size of fish entering the trawl  

Combine realtime fish echo sounder and fish imagery data from the trawl 

Keep the valuable fish and release bycatch and undersized fish  

Key Benefits

Improve catch value 

Release bycatch and undersized fish  

Trawl more efficiently and reduce fuel consumption 

Fish more sustainably

Maximized information about trawl and catch

The analysis of historical data about the catch can help in planning future hauls. In order to enhance trawl control, Deep Vision can be integrated with echo sound data and data from SYM 7 Autotrawl symmetry control. These systems combined will provide the skipper with the best possible information about the catch and trawl both in real-time and historical.  

Once the haul is over, the skipper will be able to analyze the logs from the combined systems to determine when and where the best catch occurred, how the trawl was positioned and behaved, the vessel speed and trawl movements, as well as the distribution of catch rates and species.

Main Components

Deep vision consists of the following main components:

DEEP VISON CAMSOUNDER

  • Fish more efficiently and sustainably

  • Real-time visualization of Deep Vision CamSounder data such as fish species and size distribution for the target catch and by-catch

  • Combine echo sound data, fish images, depth, and catch positioning data improving catch efficiency and catch value

  • Set automatic alerts for target fish- and by-catch levels

DEEP VISON CONTROL STATION

  • Combined real-time fish echo sounder and fish imagery data sensor

  • Fish sampling and analysis in real-time

  • Embedded algorithms and ML functionality for automatic identification of species and size

  • Send critical data in real-time to the Deep Vision Control Station on the bridge

DEEP VISON INSIGHT

  • Aggregated Deep Vision data for the whole fleet

  • Increased knowledge and understanding of the fish distribution in the water column

  • Combined deep vision data with operational data improving fleet economy and catch efficiency

  • Increase profitability and sustainability

F.A.Q

  • A subsea unit with a stereo camera, lights, battery, and acoustics will attach to the trawl net. The system will take photos of the fish that swim into the trawl. Statistical data about the species and size of fish will be transmitted acoustically to the vessel. Once onboard, the images can be transferred to the Deep Vision bridge unit and data about the catch composition of the haul further analyzed for an improved future catch or exported for reporting.

  • Deep Vision will make fishing more sustainable and profitable. It will make it possible for the skipper to take a qualified decision about what to catch based on information from Deep Vision about species and size. This will reduce bycatch, discards, and fuel consumption due to more efficient fishing operations. The value of the quotas will also be maximized as the skipper can target the size of fish that pays the maximum.

  • No, the Deep Vision subsea unit will attach to the trawl net like any other sensor. Information about the catch composition will be transmitted acoustically directly to the skipper on the bridge. Once onboard, the subsea unit will be docked for charging and transferring images to the deck unit.

  • Yes, using data from both Deep Vision images and echo sounders will really maximize the information available to the skipper and help interpret acoustic data when ambiguous.

  • Deep Vision's system for commercial fisheries will be available for sale in 2024.
