Abstract
In order that vertical distribution of some bottom fishes in the East China Sea and the Yellow Sea may be inferred for every season as well as for every division of the fishing ground, the values of mean catch (geometical means) were calculated out from the statistics data of catch as COT and CPT for otter trawl and pair trawl, respectively. Further, the ratio COT/CPT was also calculated just like the previous report1). The numerals thus obtained for 12 species of bottom fish are shown in Table 1-12 and graphycally in Fig. 1.
