Computer Housing

The computer housing stores the computer and the frame grabber which is also connected to the camera.

Camera / Light Unit

The camera looks down on the scanning area which is a 40 cm wide light protected by a clear plate. When the fish pass over the scanning area their silhouette images are registered and the fish counted.

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.


The Shrimp Pico Counter offers us great options when moving
shrimp,” says Rodney Johnson, a technician for TruShrimp
Systems. “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.



Since we have incorporated the Macro Counter into our system, we have been able to improve inventories to within 2 to 3% accuracy. I would recommend VAKI’s equipment to any large fish farming aquaculture operation
