RESEARCH PLAN AND RESULTS OF PRELIMINARY OBSERVATION ABOUT THE POSSIBILITY OF ANTARCTIC KRILL ESCAPEMENT FROM A TRAWL NET

We made a survey plan to observe krill escapement, attached an underwater video camera on a trawl net of a Japanese commercial trawler, and started observation to collect video images of krill passage through the rope and netting parts of the trawl net. Preliminary examination of video images obtained via satellite-linked transmission indicated very low incidence of krill escapement from top panels near the net opening.
