Riverwatcher, by Vaki Aquaculture Systems Ltd. products

Riverwatcher-C is our latest and most cost-effective model in the successful range of monitoring solutions for wild fish.

RW-CS is the largest model in the Riverwatcher family and it combines both IR scanning and video technology in one system. It comes with a stainless steel camera tunnel, underwater infrared and white LED lights, multiplexer, Infrared scanners, HD camera and high performance computer operating our special software to count and monitor the fish. It will count fish in both directions, log the temperature and measure size of the fish.

The Scanner is installed in fish ladders, pools, traps or similar places where all the fish in the river have to pass. It consists of two scanner plates (20 x 60 cm) inside a frame, the distance between them being from 10 to 45 cm. Inside the scanner, light diodes send infra-red light beams to receivers on the other side. When a fish swims through the net of light beams, the resulting silhouette image is used to count and estimate the size of each fish. Each individual image is memorised in the control unit so that the counting can be verified afterwards.
