This paper presents case studies on the multi-species fisheries in Korean waters, Multi-species fisheries were divided into two types, that is, multi-species by a single fishery and single species by multiple fisheries. For the case of single species by multiple fisheries, the small yellow croaker stock caught mainly by the Korean pair trawl fishery and the Korean stow net fishery was selected. This approach uses both standardized fishing efforts for the two fisheries by a general linear model and some data for the economic analysis, and then estimates maximum sustainable yield (MSY), maximum economic yield (MEY) and fishing efforts for MSY and MEY, An analysis of interaction aspects between pair trawl and stow net fisheries was carried out to predict the optimal level of fishing effort from the economic point of view, which gives the largest benefits to the two fisheries.

우리나라의 연근해어업은 다종자원을 여러 가지 어구로 동시에 어획하는 복잡한 형태를 가지고 있다. 이러한 어업에는 대표적으로 기선저인망어업, 안강망어업, 선망 어업, 유자망어업 등이 있으며, 특히 본 연구의 대상인 선망어업의 경우 고등어, 전갱이, 정어리 둥 10여종을 동시에 어획되는 다종어업의 한 형태로 취급할 수 있다. (중략)

Various types of shearing devices which may be a substitute for the conventional beams in stow nets were considered, and then tentatively named "the zonal canvas type of stow net" having the shearing device made of zonal canvas was devised. A 1/3 model of the net was made and experimented at sea. Converted to the full scale, the measured water resistance R(kg) of the net was given by $R=5.6{\times}10^{3}V^{l.5}$ or $R=3.5\frac{d}{l}{\lambda}_b{\lambda}_l\;V^{1.5}$, where V is the water velocity (m/sec), d the diameter of netting bars, l the length of the bars, ${\lambda}_b$ the stretched circumference of net mouth (m), ${\lambda}_l$ the length of net stretched. The net height kept about $83\%$ of the side rope length regardless of the variation of V and the net breadth kept a value over $90\%$ of the head rope length until V reached 1 m/sec. These results were very successful according to expectation, but the conventional netting was requested a further improvement. Therefore, the netting was newly designed to have smaller size of meshes in the vicinity of net mouth and larger hanging ratio breadthwise. With the netting a full scale net was made and experimented by a stern trawler. The experiment gave a net breadth over $95\%$ of the head rope length until V reached 1m/sec and showed no faults in the net. But the net operation by the stern trawler was ascribed an inconvenience to its narrow breadth of stern slip way.

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)

살오징어(Japanese flying squid, Todarodes pacificus)는 우리나라 전역과 동중국해에서 채낚기, 대형선망, 안강망 어업을 통하여 년중 어획되고 있으며, 1995년 이후 년간 20만 톤 이상을 꾸준히 어획하는 중요 상업 어종 가운데 하나이다(국립수산과학원, 1999).오징어는 일본의 경우 총허용어획량(TAC) 대상 어종으로 자원의 일정한 관리를 위해 음향 조사를 이용한 자원량 파악을 실시하고 있지만 우리나라의 경우 아직 TAC어종에 포함되지 못하고 있다. (중략)

갈치는 한국 동해남부, 남해, 서해 및 동중국해를 비롯하여 남중국해의 아열대해역까지의 광범위한 해역에 분포하고 있다. 이 중 한국 연근해 어선에 의해 주로 이용되는 갈치자원은 황해 및 동중국해에 분포하는 군이다. 갈치는 한국 연근해에서 1990년대 중반까지는 안강망류어업에 의해 70∼80%가 어획되었으나, 최근에는 저인망류어업 및 연승어업에 의해 각 50%, 20%가 어획되고 있다. (중략)

참조기(Pseudosciaena polyactis Bleeker)는 농어목 민어과에 속하는 어류로 한국을 비롯하여 중국, 대만, 일본 등지에 분포하며, 연간 총 어획량은 약 279,100톤으로 중국 262,800톤(94％), 한국 15,300톤(5.5％), 대 만 1,000톤(0.4％)을 어획하고 있다(FAO, 2000). 한국에서의 참조기는 황해 및 동중국해 해역에서 주로 근해안강망, 기선저인망, 유자망어업에 의하여 주로 어획되고 있다. (중략)

Yellow croaker, Pseudosciaena manchurica Jordan et Thompson, in the Yellow Sea and the East China Sea are subjected to be caught by trawl nets, stow nets and gill nets throughout the year. Monthly indices of population size are calculated. Mathematic models (I) were used in order to determine catchability coefficient, natural mortality, fishing mortality, coefficient coefficient of the fishing ground and dispersion coefficient from the fishing ground. The results are summarized as follows: 1971 1972 1973 $$Catchability\;coefficient\;(C)=1.9369\times10^{-5}\;7.5459\times10^{-6}\;1.2670\times10^{-5}$$ Natural mortality (M) = 0.1645 0.6152 0.4367 Population for the first half season (February 1 to May 31) 1971 1972 1973 Initial\;population=\;107,100M/T 209,100M/T 214,400M/T Dispersion=83,000' 159,700' 133,400' Natural mortailty= 4,700' 32.700' 19,100' Final population= 2,800' 4,500' 49,000' Population for the latter half season (June 1st to the following January 31st) 1971 1972 1973 Initial population= 44,500M/T 67,500M/T 83,800MT Recruitment= 19,000' 183,900' 67,100' Natural mortality= 5,900' 67,900' 38,500' Final population= 37,000' 168,300' 92,400'.
