Fish Migration Monitoring

Thursday, September 12, 2013: 8:00 AM-12:00 PM
Hoffman (The Marriott Little Rock)
The need for monitoring the migration of fish in rivers has never been greater, with declining stocks, polluted rivers and growing aquaculture production in critical areas.

Vaki Aquaculture Systems Ltd. has been a leading company in developing equipment for counting and measuring the size of live fish since 1986. Through continuous product development and customer contact, Vaki has adapted its products to new areas, and the fish counter for use in fish ladders, is one of our innovations. The Riverwatcher is based on the same technology that has been proven in exposed conditions in the aquaculture industry. The Riverwatcher is used in more than 300 sites all over the world including Iceland, Scandinavia, Ireland, UK, USA, Canada, Spain, Portugal, Poland, the Czech Republic, Germany and Switzerland.. In the presentation I will show some results from different rivers in Scandinavia, UK and N-America.

Various versions are available, and the counter can be adapted to local conditions in each individual instance. The Riverwatcher consists of a Control Unit with software, a Scanner Unit with a data bank and cables, solar-panel batteries and a computer program for processing the data.

Value to AFS members

Ÿ  Comparison of catch figures and the movement pattern of the fish to calculate the exploitation rate

Ÿ  Comparison of the movement pattern of the fish from one year to another

Ÿ  Evaluation of the results of rearing and smolt releases

Ÿ  Assessment of the influence of different environmental factors

Ÿ  Assessment of the efficiency of the fish ladder

Ÿ  Valuable data for better fisheries management
