Accurate Counting, High Capacity and Image Verification

VAKI Macro & Micro Counters

The VAKI Macro and Micro counters are utilized when fish are being delivering from hatcheries, or for precise stock control operations when splitting, moving, or grading are being conducted. These counters can be utilized in many applications including wellboats, helicopters and transport trucks. Additionally, commercial aquaculture operators can use the VAKI Macro and Micro Counters to provide useful stock information during the growing cycle.

Macro Counter

The Macro has a capacity of 200,000 smolts or 1 million 1g fry per hour and has a 100 cm wide counting area. With a range from 0.1g – 400g the Macro is ideal suited for accurate and fast delivery of fry and smolts. The Macro can be delivered both as single or 4 channel.

Micro Counter

The Micro is exceptionally good for hatcheries and counting small fish between 0.1g – 200g. The counting area is 50 cm wide with a capacity of 500,000 1 g fish per hour.

The Computer Program

The touch pad screen on the counter head is used to operate the counter. The main screen of the program displays numbers, average weight and through put. A graph shows the rate of fish going through the counter and the maximum capacity. Should the counter be overloaded a warning signal is given.

After each count an image file and a report file are saved. Files can be displayed on screen and transferred to a flash drive or internal network.

Recording Of Images

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.

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.

Counting Report

The counting report is produced after each count with the total number of fish counted, number in each group, total counting time, average fish/min and any counter overload time. The counting throughput graph is shown on the report and the name of site, tank, company logo, comments, and other information can be included.

With the optional size measurement function the average weight and size distribution is also included. A hard copy of the report can be printed or stored.

Size Measurements

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.

What our Customers say

“The Macro has outperformed all expectations. Speed, accuracy and low stress on the fish are key advantages”.

“We use the Micro for all counting at our cod hatchery. The Micro has proven to be very accurate and to be able to count fish down to 0.2 grams is of very big value to us”.

“The VAKI Counter is really accurate in all phases of production. Grading of the fish is also much faster. We have a lot more control on the biomass and fish number after we invested in the VAKI Fish counters”.

“Not only was the count accurate to 99.5%, but the ease and lack of stress impressed not only myself but also our customers”.
