Method and device for destroying parasites on fish

摘要

Device for destroying parasites on fish, such as salmon lice on salmon in fish farms, comprising a camera (4) communicating with a controlling unit (51) which in turn communicates with a light source (5) adapted to fire pulses of point shaped light which is harmful for the parasite in question. The controlling unit (51) controls a system for optical recognition within a defined coordinate system and is arranged to detect points and to update in real time coordinates that exhibits contrast differences typical for parasites on a fish surface and to trigger a light pulse from the light source (5) when the coordinates for at detected point coincides with the coordinates for the aiming point of the light source.

1. A device for destroying parasites on fish, comprising:
a camera arranged in communication with a controlling unit which in turn communicates with a light source arranged to emit pulses of focused light harmful for the parasite in question, the controlling unit controlling a system for optical recognition within a defined coordinate system and arranged to detect points and in real time to update coordinates of points showing contrast differences typical for parasites on fish in an aquatic environment, as well as to trigger a light pulse from the light source when the coordinates for such a detected point corresponds with the coordinates for the aiming point of the light source.
