The counter uses VAKI computer vision technology originally developed for counting fry, smolts and juvenile fish. The fish is pumped through scanner were 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 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.


All fish images are stored and can be used for verifying the count. Information about the count can be saved automatically to the VAKI Cloud.


A chart indicates the number of fish counted during the entire count and is used to select a time frame for further analysis. The screen displays images of fish passing the camera for each one-second interval.


What our Customers say

“The Shrimp Pico Counter offers us great options when moving shrimp. I also like the mobility of the unit and the computer and screen on the cart right above the camera. The great thing about the Shrimp Pico Counter is the ability to know exactly how many shrimp are in a tank when we move our shrimp in the various growth stages. Knowing this is very important so we don’t overfeed or underfeed. This gives us optimum shrimp growth and best water quality possible”.
