In order to ensure competition in the world market for Taiwan aquacultural industry, an automatic production line is a key factor. Therefore, a counting system using the image processing techniques for fish larva was developed in this study.
A counting machine for fish larva was first designed and constructed. The counting system consists of three major parts (1) provide mechanism, (2) image grabbing, processing and counting equipment and (3) export mechanism.
According to the testing results, this machine achieved a rapid recognizing and counting ability. It only required three seconds to count 139 fish larvas where as sixty-six seconds needed for manual counting one by one, 22 times of the time spent for the newly developed system. It also reached the accuracy of 91% while counting manually had only 85% accuracy.
The system of automatic fish larva counting software 1.0 (SAFC 1.0) was also developed which could be performed easily.
