In order to find out the environmental factors influencing movement of common grey mullet, Mugil cephalus in funnel net fishing ground of the Dolsan-do, Yeosu southern sea area, the oceanographic factor such as the water temperature, isobath and tidal current were observed respectively, the water temperature was compared with the amount of common grey mullet caught by funnel net. Also, to investigate the movement direction of common grey mullet in same sea area, 160 common grey mullets of body length 22 to 51cm caught at funnel nets of the Dolsan-do southern sea area were marked and then released at 5 positions in 5 times. The results obtained are summarized as follows : 1. The water temperature at the funnel net fishing ground of Dolsan-do in 2002 was ranged from 6.9 to 27.4$^{\circ}C$. The water temperature was displayed a maximum value in August to increase from March and a minimum value in February of the ensuing year to decrease from September. The catches of gray mullet caught by funnel net were generally abundant from March to September, but decreased sharply from October. The optimum range of water temperature for the funnel nets fishing was situated between 15.0 to 25.0$^{\circ}C$. 2. The isobath from 6m to 13m in coast sea set up funnel nets were densely distributed and the depth more than 14m of isobath were widely spreaded to the open sea at Dolsan-do southern sea area. 3. The tidal current of the coast sea set up funnel nets flowed southward and northward along the coast ato ebb and flood tide respectively. The direction of tidal current to the open sea was southeast at ebb tide with the mean speed 43cm/sec, but northwest at flood with the mean speed 25cm/sec. 4. The recapture rate through the experiment duration showed 9.4%. The recapture rate in Gyedong area was very high value with 33.3% as compared with others. The movement of common grey mullet in Dolsan-do southern sea area trended toward a inner bay and north bound mainly.

제주도 연안의 정치망 어업은 대모망, 소대망, 및 각망어구를 이용하고 있는데 이 어업에 대한 면허건수는 총 63통으로 이중 각망이 93％를 차지하고 있다. 정치망어업은 지역적인 환경의 영향을 크게 받는 어업으로, 특히 지리적인 특성이 해황의 변동과 더불어 내유어군의 접근과 이동에 직접적으로 영향을 끼친다(야재, 1971). 그리고 어장환경이 잘 갖추어진 어장이라도 정치망 어구 구조에 따라 어획이 변동한다고 한다(소지, 1972). (중략)

한국 근해에 분포하는 참조기는 조기류 중에서 산업적으로 가장 가치가 있는 어업자원으로서 동중국해와 황해에서 주로 근해안강망, 기선저인망, 유자망어업 등에 의해 어획되고 있다. 1970년 황해 중앙부의 연평도를 중심으로 한 참조기의 어장은 점차 남하하여 최근에는 동중국해로 이동하였으며 자원의 감소도 심각한 상태에 있다. (중략)

수괴의 분포와 이동은 어류의 분포와 회유에 영향을 미치며, 어장형성에 관여하게 된다. 남해는 다양한 종의 어류가 서식하는 우리나라의 주요 어장이며, 상업적으로도 중요한 해역으로 이 해역의 물리, 화학 및 생물학적 조사가 많이 이루어지고 있다(Gong et al.,1972; 유, 1991; 한국해양연구소,1997). 남해에 존재하는 수괴들은 계절에 따라 분포지역과 혼합율이 차이를 보이며, 성질이 서로 다른 수괴들이 만나는 곳에서는 전선이 형성된다(Pang et al., 1992; Pang and Hyun 1998; Seung 1992; Kim et al., 1991).

Variation of the catches and fishing grounds, and spawning ecology of Lophius litulon caught by large staw net were investigated from following as ; L. litulon caught through the year, and the peak in catches showed on January in winter, and the lowest catches showed on August in summer. The fishing grounds of L. litulon were located in the Yellow Sea and the East China Sea. And the main fishing ground was formed in the adjacent waters of Ilhyang-cho, where catches and CPUE were more than 50 M/T, 5 kg/haul, respectively, and the range of coefficient of variation(C.V) was 0.6~0.7. The spawning season of L. litulon was on March and April, when spawning area was formed in waters between Ilhyang-Cho and Cheju-Do. The fishing grounds distribution of L. litulon was obviously different with seasonal variation. Namely, in winter, the fishing grounds were mainly formed in the western waters of Cheju-Do, and on March and April( in spawning season), the fishing grounds were densely formed in the adjacent waters of Ilhyang-Cho, and after May, the fishing grounds were widely dispersed towards in the Yellow Sea and the East China Sea with temperature upgrade.

In order to suggest the useful information of fishing ground, a data base system on 32bit personal computer was constructed and handled by using the catch data of Korean tuna long-line, catch by species, fishing time and place, fish price and etc. mainly from 1975 to 1992. The results obtained are as follows ; In the fishing ground displaying catch rate, the catch rate has reduced as time passed, and this penomenon was more evident in Indian. And yellowfin have high catch tate in the Western Pacific of low latitute region, bigeye tuna have in the Eastern. The region of high catch rate of bigeye tuna was moved from the Indian and the Atlantic to the Pacific. The patterns of catch numbers of yellowfin and bigeye tuna appeared nearly same that, having nothing to do with catch numbers in all oceans. The region of least catch was the Northwestern Pacific, the regions of most catch were the Western Indian and the Pacific of low latitute. As to simulation of fishing ground estimation, there were economical grounds in the Western Pacific of low latitute region, the Eastern Pacific of this, the Western Indian, the Eastern Indian, and the Atlantic, in order.
