Abstract
The result, concerning the dominant or characteristic association of the benthos, in the five regions of the East China Sea and the Yellow Sea, is shown in Table ? and Fig. 1.
The relation between the good fishing ground of every valuable fish and the characters of benthos in five region is reported in this paper.
The benthos of A region is occupied by Holothurioidca, Macrura, Brachyura, and white or Yellow croacker-especially bottom fish fauna.
As for dominant and characteristic group, the following relation was found:-Ophiuroidea to Yellow croacker in B region; Asteroidea, Gastropoda to ribbon fish and yellow sea bream in C region; Cephaloda and Tetraxonida to lizard fish and gurnard in D region; Asteroidea to Black croacker in E region.
These valuable fish coincide with the majority of benthos in the superior fishing grounds, but the relation between the food habit of fish and benthic quality is unknown; the result of researches for the environmental factors managed by the majority of benthos was that oceanic current has a considerable influence upon them.
