 Considerable variation in  Atlantic salmon morphology creates challenges for developing reliable and agreed criteria for manual identification of farmed escapees. It is therefore desirable to develop a digital tool that can provide a precise and objective classification of salmonids with associated uncertainty . Thus, the IdentiFish  project  was established  to develop a general and precise machine vision to distinguish between escaped and wild salmon.

Based on  a unique  data  set  collected through a n ational m onitoring p rogram for escaped farmed salmon in Norwegian water courses and  a commercial  salmon fishing app Elveguiden , the project group will develop a model for distinguishing escaped farmed salmon from wild salmon using machine vision . While t he national monitoring program surveys ~200 rivers annually, Elveguiden collaborates with over 500 management teams and landowners  and  has over 55,000 registered  anglers on the platform.

The machine vision model  will be  made  publicly  available on the Institute of Marine Research’s website, and at the same time  implemented in  Elveguiden’s app.  An app capable of distinguishing between escaped and wild salmon using machine vision can contribute to more precise monitoring of escape events. Immediate classification via app provides opportunities for rapid reporting to management authorities  which can  reduce the reaction time to implement necessary measures, such as targeted recapture as well as  limit the extent of the escape event  and  thus minimize financial losses.

 The project is an example of how artificial intelligence can be used to strengthen monitoring of wild salmonids  and contribute towards sustainab le aquaculture production.  The project is funded by the  Norwegian  Seafood Research Found (FHF 901937) and is a collaboration between  researchers,  developers, and entrepreneurs: Norwegian Institute of Marine Research, Elveguiden (https://elveguiden.no/en) , Norwegian Veterinary I nstitute and Norwegian  Institute for Nature Research.
