Abstract
The present invention pertains to a method for automatic sea lice monitoring in fish aquaculture, the method comprising submerging a camera (4) in a sea pen (300) comprising fish, using the camera to make an image of at least one of said fish, analysing the image to differentiate between individual sea lice present on the fish and the fish itself and assessing the number of sea lice present on the fish, wherein the camera is attached to a device (1, 10, 100) for guiding the salmon along an imaging track (5), the camera being directed to the track.
Claims18
Method for automatic sea lice monitoring in fish aquaculture, the method comprising:
- submerging a camera (4) in a sea pen (300) comprising fish,
- using the camera to make an image of at least one of said fish,
- analysing the image to differentiate between individual sea lice present on the fish and the fish itself,
- assessing the number of sea lice present on the fish,
- characterised in that the camera is attached to a device (1, 10, 100) for guiding the salmon along an imaging track (5), the camera being directed to the track;
- and wherein the device comprises a radial enclosure (11, 101) to confine the track.
A system for use in salmon aquaculture to automatically monitor and report sea lice presence on fish, the system comprising
- a central processing unit (CPU;
- 200)
- connected to the CPU a camera submerged in a sea pen comprising the fish, the camera being devised to make images of said fish, wherein the camera is attached to a device for guiding the fish along an imaging track of this device, the camera being directed to the track wherein the system comprises a radial enclosure (11, 101) to confine the track,
- imaging software running on the CPU to analyse images of the fish made by the camera, to differentiate between individual sea lice present on each of the said fish and the fish themselves, and to assess the number of sea lice present on the fish,
- a reporting unit (204, 206) connected to the CPU, to display a results corresponding to said assessing.
A device for making images of fish present in a sea pen, the device comprising a camera and a track for guiding a fish through the device, the device comprising an enclosure that confines the track, wherein the camera is attached to the enclosure and is directed to the track, wherein the enclosure is a radial enclosure (11, 101) to confine the track.
