抄録

In accordance to findings on dissolved oxygen distribution in the bottom layer of Omura Bay, trawl fishing was conducted by using a “kogata-sokobiki” type net, and the following results were obtained.<br> Oxygen distributions affect the distribution of bottom living organisms and an oxygen content lower than 1 ml/l appeared to be an extremely unfavourable environment for such organisms.<br> Bottom living organisms for the most part lost their activity and died massively. Those that could avoid the low oxygen environment aggregated toward better conditioned environ-ment and formed the fishing area.
