抄録

In order to obtain more knowledge about the control of a midwater trawl system, three electronic instruments were produced by way of traial to measure the motions of both the otter-boards and net under trawling operations with a full-scale net. These devices were used on the sampling trawl experiment. They were mounted on both otter-boards and the net to measure their depths. After the experiment, these data were analysed to clarify each otter-board's motion more exactly. These self-recording underwater instruments store measurement data into IC memories and, after each haul, feed the collected information to the computer.
