  • Eighteen species of fish were identified by SCUBA diving observations around experimental artificial reefs at Tongyeong marine ranching area between November 1998 and November 1999. The highest species number of 14 was observed in September while the lowest number of 2 was observed in November. Fishes showed three typical behavioral patterns against the experimental artificial reef.

It contains the status of Korean fisheries industry, background and the scope of ranching project being conducted by KORDI since 1996. Long term plan for the marine ranching programme as a national project is also introduced including socio-economic analysis of project as well as economic impact of investment.

  • The feeding habits of Sebastes schlegeli collected from the Tongyeong marine ranching area throughout 2002 were studied. S. schlegeli is a carnivore (piscivore), and consumed mainly fish. Its diet also included a small amount of caridean shrimps, crabs, amphipods, polychaetes, and isopods. The diet of S. schlegeli underwent size-related changes. Small individuals (standard length (SL)<6 cm) fed mainly on fishes, caridean shrimps, and amphipods, and the proportion of fish increased with SL. Large individuals (SL>20 cm) ate fish predominately. The diet of S. schlegeli changes seasonally, and caridean shrimps were consumed mainly from May to July. The dietary breadth index of S. schlegeli varied with SL and season.

  • 2000년부터 2002년까지 통영 바다목장 해역 5개 정점표층수와 저층수에서 종속영양세균의 개체수를 평판계수법으로 측정하여 종속영양세균군집의 계절별 변동추이를 비교 분석하고, 우점종을 선별하여 동정하였다. 7월과 8월의 하절기에 채수한 해수에는 봄 혹은 가을 및 겨울에 채수한 해수에 비하여 모든 정점에서 훨씬 더 많은 종속영양세균이 검출되었다. 저층수에 비하여 표층수에서 종속영양세균의 수가 더 많았으나 동절기(2001년 12월과 2002년 2월)에는 해수 온도가 낮으며 해수의 대류가 느려짐에 따라 부유물질이 저층에 축적되는 관계로 저층수의 종속영양세균의 수가 표층수의 경우 보다 오히려 더 많이 검출되었다 해수 내 종속영양세균의 수와 태풍의 빈도는 뚜렷한 상관관계를 보이지 않아 태풍의 빈도 이외에 태풍의 진로와 강도 및 태풍을 수반하는 집중 호우와 해수의 온도 변화가 종속영양세균의 수에 영향을 미치는 것으로 판단되었다. 통영 바다목장 해역의 종속영양세균의 우점종은 Pseudomonas fluorescens, Pseudomonas stutzeri, Acinetobucter lwoffii 및 Sphingomonas paucimobilis로 동정되었다.

  • This paper aims at overviewing Korean fisheries profile with a view on why Korean fisheries need marine ranching program as a new fisheries paradigm - a community-based co-management approach and drawing some policy implications from the advanced experience in fisheries. The aims of community-based co-management approach as a planned approach can be set out under the planning objectives of efficiency and equity. In this context Tongyeong marine ranching program is an important government-sponsored pilot enterprise. Experiences in the advanced fisheries such as Canadian Snow-Crab case suggest that in order to be successful for marine ranching be successful it is necessary that (i) there should be high-value species, (ii) property right should be established, (iii) there should be the reasonable number of participants involved, (iv) the participants and the government should be able to share resource enhancement/management/utilization responsibilities and associated fisheries management expenses. Among these, management cost sharing based on the practical partnership between fishing communities and government is of particular importance because the government must have a full responsibility for all ranching program expenditure unless revenues sufficient to guarantee reasonable income and to share management cost are generated from the ranching business.

  • 본 연구는 2001년 7월부터 2004년 5월까지 29개월동안 매월 경상남도 통영 바다목장해역에서 채집된 총 1,173마리의 조피볼락의 이석을 사용하여 연령과 성장을 연구하였다. 윤문은 불투명대에서 투명대로 이행되는 7월에 형성되었다. 주성숙기는 1월이며 산출시기는 2~5월 사이로 조피볼락의 초륜이 형성되는 시간은 주성숙기인 1월부터 이듬해 7월까지 약 1.5년으로 사료된다. 추정된 조피볼락의 von Bertalaffy length식과 weight growth equation식은 암컷은 $L_t=48.45(1-e^{-0.2139(t+0.4313)})$, $W_t=1,837.93(1-e^{-0.2139(t+0.4313)})^{3.02}$이었으며 수컷은 $L_t=49.32(1-e^{-0.1775(t+0.7403)})$, $W_t=1,887.83(1-e^{-0.1775(t+0.7403)})^3$였다.

  • In order to understand variation and relationship between standing crops and biomass of phytoplankton dominant species for the long term periods, this study was seasonally investigated in the marine ranching ground of Tongyeong coastal waters from 2000 to 2007. Total 268 taxa representing 217 Bacillariophyceae, 46 Dinophyceae, 4 Dictychophyceae, 1 Euglenophyceae were observed in phytoplankton communities. Dominant species consisted of 5 species as standard in standing crops: Chaetoceros curvisetus (18.01%), Chaetoceros socialis (12.95%), Skeletonema costatum (8.39%), Chaetoceros compressus (6.87%), Asterionellopsis glacialis (5.02%). However, to determine dominant species as biomass concept, Ditylum brightwellii, Guinardia striata, Rhizosolenia spp. and Skeletonema costatum were occupied with dominant species (19.67%). As determining for cell sizes, dominant species were divided with two groups such as micro- and nanophytoplankton (standing crops) and mesophytoplankton (biomass). However, Skeletonema costatum in anophytoplankton was associated to affect fluctuation between standing crops and biomass.

  • 본 연구는 2003년 8월에 통영 바다목장해역 5개 정점 표층수에서 페놀류, 9개의 폴리클로리네이티드비페닐(PCB) 및 유기주석화합물(TBT)의 농도와 10개 정점에서 수은 및 크롬(VI), 카드뮴, 납의 중금속 농도를 해양 환경공정시험방법(해양수산부 2002) 또는 이 방법과 내분비계 장애물질의 측정 분석방법(국립환경연구원 1999)을 일부 변경하여 분석하였다. 환경정책기본법시행령(대통령령 제18108호: 별표 1, 3. 수질, 라. 해역)에 의하면 페놀류: 5 ppb, PCBs: 0.5 ppb, Hg: 0.5 ppb, Cr (VI): 50 ppb, Cd: 10 ppb 및 Pb: 50 ppb이고 유기주석화합물의 기준은 나타나 있지 않다. 본 해역에서는 페놀류: 1.6$\sim$2.8 ppb, PCBs: 검출되지 않음, Hg: <0.1 ppb, Cr (VI): 0.01$\sim$5.32 ppb, Cd: 미 검출$\sim$0.41 ppb 그리고 Pb: 0.43$\sim$2.60 ppb로써 사람의 건강보호 기준에 적합한 해수로 판단되었다. 유기주석화합물(TBT) 중 Sn의 농도는 미 검출$\sim$0.0273 ppb로써 1998년, Shim et al. (1998)에 의하여 조사된 진해만의 해수 중 TBT의 농도: 8$\sim$35 ng Sn $L^{-1}$ (즉 Sn:0.008$\sim$0.035 ppb)와 유사한 농도였다. 따라서 본 연구에서 조사된 통영 바다목장의 해수는 사람의 건강 기준에 적합한 수질로 판명되었다.

  • The species composition and abundance variations of fishery resources in the adjacent marine ranching area, Tongyeong, Korea, were investigated by shrimp trawl, gill net, and longline during the period of July, September, and October in 2016. During the study period, the total catch were 8,522.9 kg with 34 species from the shrimp trawl, 32 species from the gill net, and nine species from the longline. The dominant species were different by gear, which were Hypodytes rubripinnis and Parapercis sexfasciata in the shrimp trawl, Platycephalus indicus and Raja kenojei in the gill net, and Conger myriaster and Scomber Japonicus in the longline. In terms of spatial distribution, Yongchodo showed the highest total catch in number as well as of in weight while Jukdo showed the lowest total catch in number and Bijindo showed the lowest total catch in weight. The amount of demersal fish resources in the survey area estimated as 301 ha, was 99,396 individuals which was converted to be 8,552.9 kg. The amount of demersal fish resources by gear were of trawling area, which area is 127 ha, were 76,251 and 3,489.5 kg, 74 ha in the gill net and longline survey area was 16,213 and 3,457.3 kg, and the other 100 ha area was 6,932 and 1,606.1 kg. In this study, the minimum resources for demersal fish is 61,687 and 4,265.2 kg, and the maximum is 149,439 and 14,197.9 kg.
