The Riverwatcher currently counts and monitors migration patterns of fish in over 500 rivers worldwide, in fish ladders, weirs and passes. The scan and camera technology gives you the ability to know your river and compare fish migration patterns year over year. You need to monitor fish migration. You can use a counting window in a fish pass or install an underwater video camera and watch endless hours of pretty much nothing but occasionally a fish.  This can be very time consuming and inefficient. The. Riverwatcher monitors, counts and measures each fish for you, daily. Compared to other methods of accurately counting fish and monitoring your river, the Riverwatcher gives you 365 days of data and saves you money in time and resources, year after year. It is fully automatic and requires minimal maintenance. Manual surveillance is human resource intensive, involves commuting to remote areas and gives you a picture of a single point in time. Riverwatcher generates valuable information daily about the environment and about the fish that pass through the river. If you have equipped your Riverwatcher with a Biomark PIT Tag antenna systems, you will also receive additional unique data on each fish. You don´t have to go to the river to check what´s going on anymore. The new online software module, Riverwatcher Daily, makes it easy for you to access river information daily, as the data is automatically uploaded to the cloud and accessible from any internet-connected device. The Riverwatcher online software displays migration patterns based on the size of the fish, the direction of the fish, time of migration, the temperature of the water and comparison between years. Data is tracked automatically, on a daily basis. You may have several people that need to access this data. No problem. Each member can have a login and you control how much you want to show in public view. Only signed-in users can edit data and add categories. We love fish videos, who doesn’t? Check out the biggest fish, the latest fish or have your system display a looping window of the last few passing fish for everybody to enjoy. The Riverwatcher is typically installed in a fish-pass or a fish-way of some kind. It gives valuable information about the efficiency and the design of the structure. Custom designs are available to retrofit to our existing environment or build in as a component of a new fish pass. Independent studies have shown the Riverwatcher to be more accurate than other types of fish counters, counting fish with 98% accuracy and measuring the size of each fish with more than 95% accuracy. The Vaki Riverwatcher has been installed in over 500 locations and proven itself in harsh conditions all over the world. With global service and support, we want to support your conservation needs.
