The VAKI Wellboat Channel Counter is particularly useful during splitting and grading operations, as it provides critical data on the number of fish in each size group. This data allows commercial aquaculture operators to gain key insights upon which they can base ongoing feed planning. The Wellboat Channel Counter also provides a documented counting report and it records images of the actual count for future validation.

The B-Type

Refers to the box design and is used when it is not required to lead the fish into a pipe after counting. This version is commonly used on barges when fish are being pumped directly from one cage to another.

The Y-Type

Used on large grading machines when the fish is transported from the grader into a pipe after counting. The pipe diameter can be up to 20".

Counting software

Full control from the bridge of the wellboat

The counting technology

The counter uses VAKI computer vision technology originally developed for counting fry, smolts and juvenile fish. Fish pass over a light source where an imaging line scanning camera is used to grab silhouette image of every single fish. The silhouettes are analyzed and used for counting and size estimation.

The Counting Software

The advanced software is used to count the fish as they pass the counting area. All fish images are stored and can be used for verifying the count. The screenshot to the right shows one second of smolt counting where the capacity is up to 100 fish per second.

Macro App

Among other features the Macro app provides the user the option to run the counter, view the results and email the count report from a smart phone or tablet.

Automatic Report Function

The automatic count report gives valuable and detailed information on the counting. The report can be supplied to the receiver of fish along with the counting file containing the images of all the fish. The throughput chart shows the rate of fish passing thru the counter. With this information the quality of the count can be assessed by checking for any overload time.

Size Estimation

The average weight and the size distribution of the counted fish are shown on a graph along with information on the total biomass of the fish.
