To examine species composition, abundance and biomass of fishes in the northwestern East Sea of Russian EEZ, trawl survey were conducted at 31 sampling stations from 2006 to 2008. Also, trawl survey were conducted at 21 sampling stations in the southwestern East Sea of Korean EEZ from 2006 to 2008. A total of 67 fishes were collected in the northwestern East Sea of Russian EEZ, a total of 39 fishes were collected in the southwestern East Sea of Korean EEZ. Among them, a total of 53 fishes were collected in the northwestern East Sea of Russian EEZ only, and a total of 25 fishes were collected in the southwestern East Sea of Korean EEZ only. Mean abundance per area which caught by trawl survey in the northwestern East Sea ranged from a high of 116,478 inds./km2 in 2008 to a low of 19,737 inds./km2 in 2006. And mean abundance per area in the southwestern East Sea ranged from a high of 89,129 inds./km2 in 2006 to a low of 8,234 inds./km2 in 2008. Mean biomass per area which caught by trawl survey in the northwestern East Sea ranged from a high of 11,333 kg/km2 in 2008 to a low of 2,439 kg/km2 in 2006. And mean biomass per area in the southwestern East Sea ranged from a high of 6,273 kg/km2 in 2006 to a low of 1,062 kg/km2 in 2008. Cluster analysis, based on a Bray–Curtis similarity matrix of fourth root transformed data of number of species and individuals per area, showed division into three different groups by depth in the northwestern and southwestern East Sea.
This study estimated quantitatively the loss of the fisheries due to China’s illegal fishing that prevailed in the EEZ of the country in recent and has been an object to present a basic data in the implementation of government policy as to strengthen the enforcement capacity, setting up the direction of the crackdown of Chinese through to figure out an objective loss according to that. The analyzed result of this study setting a reasonable scenario, fisheries resources reduction is estimated about 67.5 million ton and the estimated amount of the loss is about 1.3 trillion won. This is 21.2% of about 318.3 ten thousand tons of the total fishery production of the country and accounts for 61.9% compared to coastal and offshore fisheries production. Therefore it is a very serious problem due to China’s illegal fishing in Korea fisheries sector. It is significant to the point that estimating the qualitative and quantitative losses that can achieve a realistic and effective policy.
이 논문은 일본의 배타적 경제수역(EEZ)에서 한국어선의 피납실태를 분석하여 그러한 문제에 대한 대응방안을 제시하는 것을 그 목적으로 한다. 일본의 배타적 경제수역에서 벌어지고 있는 한국어선의 피납실태를 분석해 보면 우리나라의 어민들이 연근해 수산자원의 고갈과 해양오염으로 인하여 연근해조업이 곤란한 상황에서 수산자원이 풍부한 일본의 배타적 경제수역 경계선 부근이나 경계선을 침범하여 조업을 하고 있는 것으로 나타난다. 과거에는 그러한 행위가 관행상 자유로운 공해상의 조업이었지만 UN해양법협약(1994)과 한일어업협정(1999)이 발효함으로써 범법 행위가 되었다. 그러한 문제를 해결하기 위해서는 장기적인 관점에서 어업정책의 방향전환, 어민들의 생계대책마련 및 한일양국의 어업관리 협조체제의 구축이 필요하다. 무엇보다 당장 시급한 것은 외국에서 집행된 형의 감면이며, 어업지도와 단속을 위한 인적·물적 자원의 확충 및 해양경찰과 해양수산부의 긴밀한 공조체제 구축도 시급한 것으로 보인다.
