Fish Monitoring

Footage to verify scanner results

Fish monitoring equipment from Vaki, Iceland

To compliment ACE’s range of fish and eel pass equipment, ACE are the sole UK supplier of the Vaki Riverwatcher range of fish monitoring technology, providing the ultimate recording and verification of fish migration. Where other counters and cameras offer limitations in results or require unworkable man-hours in verification of results, the Vaki surpasses all expectations.

 

  • Precise counting and grading of fish size (up to 98% accurate)
  • Validation of data using shadow-imaging and real footage
  • Only records passage- removes endless hours of non-migration footage
  • Easy access- using Riverwatcher daily, even remote access is available

 

The Vaki Riverwatcher is an evolved fish counter, using Vaki’s expertise in high volume counting in fish-farming, which when put to use in rivers exceeds all alternative methods in flexibility, reliability and value for money.

The Vaki Riverwatcher uses advanced technology at the head of fish passes or intakes, by taking a series of scans (50 times per second) when a fish enters the scanner section. The hardware then uses intelligent software to produce an accurate silhouette of the fish, allowing validation not only that the scan is indeed a fish, but also allow sizing and classification of species to be determined. Where conditions allow, the scanner can also be fitted with a real-image camera, to validate results with 100% certainty. The use of video validation and RiverWatcher daily provides invaluable information on fish migration patterns and behavior.

 

Vastly reduced labour costs

Validation using traditional methods often prohibits lengthy studies, due to the majority of the footage gathered showing no passage, and images that are unclear or open for doubt. With the Vaki Riverwatcher, this is a thing of the past- the camera system only records triggered events, so the results you get are of passage, and even if debris has triggered the camera, it can be discounted with certainty- the Vaki provides the most accurate, wholesome results, with the minimum of wasted time and resource. The value of the results obtained clearly justifies the purchase of the Vaki Riverwatcher, with the return on investment being very quick indeed.

The RiverWatcher is also available for eel passes, to allow accurate monitoring of eel migration.

 

Access and information sharing

Using Riverwatcher daily, you can access the camera and records from the comfort of your desk, via a secure portal on the web. The portal can be shared among your piers, or even with the public if desired, to allow the data to be reviewed conveniently. The information gathered shows the shadow of each event, along with the fish’s size, time of passage and where fitted, a photograph- this allows in depth assessment of the passes effectiveness, patterns of migrations and countless other studies.
