한국 근해의 서남해 및 동지나해에 있어서 최근 16개년간($1970~1985$)의 안강망에 의한 병어어획통계자료로 부터 병어류의 분포 및 회유와 해양환경에 따른 어황을 살펴본 결과는 다음과 같다. 병어류의 주요 어장은 제주도와 양자강하구를 잇는 선상에 위치한 대양자사퇴역으로, 병어류가 어획되었던 분포역은 전면적의 약 $11\%$에 해당하는 14개 해구에서 전어획량의 약 $70\%$를 차지하고 있었다. 전해구에 걸쳐 어획량의 변동 계수는 0.01 미만이었으며, 14개 주요 어장의 변동 계수는 $0.001~0.003$으로 특히 작았다. 또한, 이 해역은 춘계부터 추계까지 황해난류의 유입이 뚜렷하며, 중국대륙연안수와 황해저층냉수 및 쓰시마 난류 사이에 뚜렷한 전선을 형성하고 있는 혼합수역이었다. 병어류는 쓰시마 난류와 황해저충냉수의 소장에 따라 남북회유를 한다. 즉, 하계에는 황해북부로, 동계에는 동지나해 중부이남의 월동장으로 회유한다. 병어류 어획 수형의 최대빈도범위는 수온 $10~12^{circ}C$ 염분 $32.4~33.4\%_{circ}$로, 이 범위에서 어기별 총 어획량의 $70\%$ 이상을 차지하였으며, 한어기와 성어기에 따른 최다어획 수형빈도범위는 차이가 없었다.
Basedon statistical data of pomfret (Pampus spp.) catches by the stow net during $1970~1985$, the distribution and migration of pomfrets and fishing conditions were investigated in relation to oceanographic conditions, in the East China Sea and the Yellow Sea. The main fishing grounds of Pomfrets were formed around the Great Yangtze Sand Bank which locates between the Cheju Island and the mouth of the Yangtze River. Its area occupied only 11 percent of all fishing grounds, and about 70 percent of total catch was found there. The coefficient of variation(CV) in catch was below 0.01 in the whole fishing grounds and that of tile main fishing grounds (14 fishing areas) was $0.001~0.003$. This area was indicated markedly by the inflow of Yellow Sea Warm Current from spring to autumn, and this mixing area which formed the oceanic front among the China Continental Shelf Water, the Yellow Sea Bottom Cold Water and the Tsushima Warm Current. The pomfrets migrates to south-north according to the expansion and contraction of the Tsushima Warm Current including the Yellow Sea Warm Current and the Yellow Sea Bottom Cold Water. Therefore, it migrates to north of the Yellow Sea in summer and to southern part of the East China Sea in winter. The most frequent range of the water type for high catch was $10~12^{circ}C$ in temperature and $32.4~33.4\%_{circ}$ in salinity. The ranges was occupied more than 70 percent of total catch on fishing season. The frequency range of the water type was not different between the abundant fishing periods and the poor fishing periods in terms of the maximum catches.
