Wellboat Channel Counter

Accurate Counting, High Capacity and Image Verification

Wellboat Channel Counter

The Channel Counter is particularly useful during splitting, grading operations or lice treatment, 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 Channel Counter also provides a documented counting report and it records images of the actual count for future validation. The Channel Counter is ideal for accurate counting and size estimation of large numbers of live fish from 50g upwards. The Channel Counter has been designed to accurately count at the high capacities achieved by modern fish pumps and fish transport systems on wellboats. It is the best choice for obtaining reliable and verifiable stock information when splitting, grading and harvesting.

The Channel Counter can be delivered in three sizes and two versions


The B-Type

The B-type is used when it is not required to lead the fish into a pipe after counting. Commonly used on barges when fish are being pumped directly between cages.


The Y-Type

The Y-type is used on large grading machines when the fish are transported from the grader in a pipe after counting. The pipe diameter can be up to 20″.

Full control from the bridge of the wellboat


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 analysed and used for counting and size estimation.


The images of the fish are automatically recorded and can be used to validate and check the accuracy of the count. The image file can be given to a customer and / or stored as a permanent record.

The red chart indicates the numbers of fish counted during the entire count and is used to select a time frame for further analyses. The screen displays images of fish passing the camera for each one second interval. Accuracy can be verified by a manual check of the number of fish images to the count shown on the screen.


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.


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.


An optional feature to the counting program, the size measurement module, presents accurate average weight and size distribution of the counted fish.
In one simple operation complete data on number and size of fish is obtained without handling or stress.

VAKI SmartFlow

The SmartFlow System gathers information from all devices. This facilitates the optimization of every grading/ counting operation as the various devices can be controlled and fine-tuned electronically in order to result in more precise controlled output.

VAKI Cloud

The VAKI Cloud is the online location to store and access all  your VAKI Counter Reports ,  fish images and smart flow grading reports. All VAKI Counters and Graders have the ability to automatically backup the files to VAKI Cloud.

With a secure Log in the VAKI Cloud will also allow access to current operational status and service information for your VAKI equipment in the VAKI Customer Care Program.
