The answer is not really. If the fish came through the narrow part of the net in dribs and drabs, then counting and sorting would be easier. However, sometimes they come through the net at what seems to be blinding speed and frequency. I have watched the video and, like most, I could pick out obvious fish species and numbers. However, at best, that was about 5 percent of what went through. So, the researchers would actually fish with a cod end in place as well as the cameras. That way they could simply count and sort the fish caught and compare that to what was observed on the video. Over time, they should be able to program a computer to do the observation and counting in a lab setting. It will take time and a bunch of tows where the actual catch is calibrated to what the computer sees, but it could make the ocean fish data collection a lot easier and benign to the fish.
