Abstract :
A non-intrusive method for monitoring salmon stock has been developed which includes the use of two matched monochrome CCD cameras. Stereo image sequences are grabbed and digitised. The images are used to calculate various measurements from the fish, which are then used to estimate its mass. Methods for estimating the fish mass have been investigated. An image analysis algorithm for locating salmon from an underwater image has been developed and more advanced techniques are under development
