An expert-informed method for automatically identifying the locations of fishing grounds by training a computer to recognise fishing behaviour in vessel GPS tracking data.

Methods generally used to quantify fishing effort from tracks depend on knowing what the boat is doing in advance, this is, what is the target species and what gear is the boat using. This type of information is not always available, either because it wasn’t recorded or because the fisher changes targets and gears frequently. {scram} allows quantifying effort in theses fisheries by automatically recognising fishing activity without any prior information, a powerful tool not only for identifying not only the spatial behaviour of fishers, but also animals.
