Sockeye salmon census using computer vision

 

Continuous counting of the Ozernaya sockeye salmon at the scientific observation post of the Kamchatka branch of the Russian State Research Center "All-Russian Research Institute of Fisheries and Oceanography" (VNIRO) has been carried out for more than 80 years. Until 2021, only visual counting was used, since 2021 - the collection of photos and videos of sockeye salmon that passed through the FCF checkpoints.

 

In 2024, as a result of processing the data array using machine learning of artificial neural networks, a model for detecting objects was created that can recognize spawning sockeye salmon in a static image or video recording, an algorithm for counting fish was developed.

 

The deployment of an artificial neural network for processing images transmitted from video cameras will automate the process of identifying and recording fish at the existing fish farm without the need for human intervention and will prevent possible subjective errors during the recording work.
