황선도(Sun Do Hwang),임양재(Yang Jae Lim),김용철(Yong Cheol Kim),차형기(Hyung Kee Cha),최승호(Seung Ho Choi) 한국수산과학회 1998 한국수산과학회지 Vol.31 No.5

Seasonal species composition of fishery resources was determined using samples collected by a stow net from April 1995 through January 1996 at 9 stations off Youngkwang. Catch data obtained from a set net using strong tidal current could be used for a quantitative analysis of dominant species. Of the 98 species identified, assemblages were consisted of 52.0% in fishes, 44.6% in shrimps, 2.0% in cephalopods, 1.4% in crabs and <0.1% in gastropods. Thryssa kammalensis, Crangon hakodatei, Metapenaeus joyneri and Johnius grypotus predominated in abundance, consisting of 68% in the number of individuals. The abundance and species composition fluctuated seasonally, and species could be distinguished by life history pattern with seasons. Seasonal variation in species composition was greater than the spatial variation in a sampling period. As the fine sediment was predominated in the study area, the species composition were significantly different from those of other coastal waters of West Sea, Korea.

황선도,이우주,임양재,Hwang, Sun-Do,Lee, Woo-Joo,Im, Yang-Jae 한국해양학회 2012 바다 Vol.17 No.3

서해안 연안역과 하구역의 유영생물의 종조성 변동을 파악하고, 두 해역간의 생산성을 비교하기 위해서 2010년 3월~12월의 대조기에 하구역인 강화도과 연안역인 장봉도에서 주목망으로 24시간 동안 어획된 유영생물을 수집하였다. 유영생물의 군집구조는 해역별, 월별, 분류군별 양적 차이를 보였으며, 유영생물의 종다양도는 연안역보다 하구역에서 낮았으나, 생산력은 하구역에서 더 높았다. 강화도 주변 하구역에서는 싱어, 가숭어, 황강달이가 연안역에서 보다 많은 양이 빈번히 출현하여 기수종이 우세하였고, 연안역인 장봉도 주변 해역에서는 해양종으로 분류할 수 있는 청멸, 밴댕이, 꽃게가 하구역에서 보다 많은 양이 자주 출현함으로써 유영생물이 서식처에 따라 공간적 분포를 달리함을 확인할 수 있었다. 그라비새우, 밀새우, 풀망둑 등은 연안역과 하구역에서 양적으로나 출현 횟수가 비슷하여 하구와 연안을 왕래하는 종으로 판단된다. 하구 생태계의 건강성을 과학에 근거하여 평가함은 하구의 효율적인 관리를 위해서 정책의 우선순위를 결정하고 관리방향을 설정하는데 유용하게 활용될 것이다. To elucidate the species compositions of estuarine and inshore fauna and compare productivities between them, catch were collected by bag nets in the Han River estuary off Ganghwa Island and the inshore waters off Jangbong Island for 24 hours at the spring tide from March to December 2010. Community structures of nekton assemblages were different with area, month, taxonomic groups. Although the diversity of estuarine nekton assemblage was lower than that of inshore nekton assemblage, the productivity of nekton assemblage in estuary was higher than that in the inshore waters. Nekton assemblages were distributed according to habitat environment: the estuarine species, Coilia mystus, Chelon haematocheilus, Collichthys lucidus were prominent in the Han River estuary off Ganghwa Island, and marine species, Thryssa kammalensis, Sardinella zunasi, Portunus trituberculatus were prominent in the inshore waters off Jangbong Island. Palaemon gravieri, Exopalaemon carinicauda, Synechogobius hasta were inhabited in both waters. The health assessment of estuarine ecosystem based on scientific research will be contributed to the effective management of estuary with determination of order and direction in policy.

황선도 ( Hwang Seon Do ),김종식 ( Kim Jong Sig ) 한국수산과학회 2003 한국수산과학회지 Vol.36 No.6

N/A Species composition and distribution patterns of shellfish were investigated in Eoeun and Geojeon tidal flat located in the Saemangeum area on the west coast of Korea from May to October 2000. Nineteen species of shellfish were collected in Geojeon tidal flat. The samples in number of individuals included Umbonium thomasi (90.0%) and Mactra veneriformis (5.0%). In Eoeun tidal flat, ten species of shellfish were collected and the dominant species in number of individuals were Potamocorbula amurensis (55.O%) and U. thomasi (18.6%). These results were compared with previous studies conducted before the beginning of reclamation in Saemangeum. Compared with the results from 1988, a change in species composition was observed. Laternula flexuosa and Nuttallia olivacea appeared, while Mactra chinensis and Coelomactra antiguata disappeared in the deposition area in Geojeon tidal flat. In the erosion area of Eoeun tidal flat, M. veneriformis and Meretrix lusoria appeared, while Cyclina sinensis disappeared. Based on a cluster analysis, the shellfish community in Eoeun tidal flat was classified into three station groups based on sediment types. Geojeon tidal flat was also classified into three station groups. The distribution of shellfish in the Saemangeum area was closely related to the sediment types.

황선도,노진구,Hwang, Sun-Do,Rhow, Jin-Goo 한국해양학회 2010 바다 Vol.15 No.2

한강 하구의 기수역에서 유영생물의 종조성과 계절 변동을 파악하기 위하여 2009년 2월부터 12월까지 매월 1회 강화 석모 수로에 설치된 연안개량안강망 1틀을 이용하여 24시간 동안 유영생물을 수집하였다. 채집된 유영생물은 총 86종으로 그중 어류가 54종으로 가장 많았고, 새우류 16종, 게류 등의 갑각류 12종, 두족류 3종 그리고 1종의 해 파리가 출현하였다. 전체 유영생물 중 밀새우(Palaeman carinicauda)가 10회 출현에 개체수로 32.6%로 최고 우점 하였으며, 젓새우(Acetes japonicus) 15.9%, 그라비새우(Palaemon gravieri) 9.9%, 꽃게(Portunus trituberculatus) 7.7%, 중국젓새우(Acetes chinensis) 6.9%로 이들 갑각류 5종이 총 개체수의 73.0%를 차지하였다. 한강 하구역 유영생물 군집구조는 봄과 가을에 개체수와 양적으로 번성하였고 높은 다양성을 보이는 전형적인 온대 해역의 특징을 보였다. 우점종을 서식처에 따라 구분하면, 웅어(Coilia nasus), 가숭어(Chelon haematocheilus), 숭어(Mugil cephalus)와 풀망둑(Synechogobius hasta), 오셀망둑(Lophiogobius ocellicauda), 아작망둑(Tridentiger barbatus), 밀새우, 그라비새우는 기수성 주거종으로, 싱어(Coilia mystus), 풀반지(Thryssa hamiltonii), 풀반댕이(Thryssa adelae), 밴댕이(Sardinella zunasi), 멸치(Engraulis japonicus) 등의 청어목 어류와 꽃게, 젓새우 그리고 황강달이(Collichthys lucidus), 병어(Pampus argenteus) 등은 연안 회유종으로, 뱀장어(Anguila japonica)는 왕복성 어류로 분류된다. 한강 하구의 경우, 기수성 어종이 우점하고, 펄을 서식처로 이용하는 새우류가 어류보다 양적으로 우세하며, 주둥치와 같이 환경이 악화된 해역에 서식하는 종이 채집되지 않음으로써 자연 하구의 생태계 구조를 유지하고 있는 것으로 판단된다. Seasonal variation in species composition of estuarine fauna in the Han River estuary was determined using monthly samples collected near Ganghwa Island by a bag net from February to December 2009. Total number of species was 86: 54 species of fishes, 16 species of shrimps of crustacean, 12 species of other crustacean such as craps and so on, 3 species of cephalopods and 1 species of jellyfish. Of a total of 86 species, Palaeman carinicauda (32.6%), Acetes japonicus (15.9%), Palaemon gravieri (9.9%), Portunus trituberculatus (7.7%) and Acetes chinensis (6.9%) were predominated in abundance. These 5 crustacean accounted for 73% of total. Abundance, biomass and diversity of Han River estuarine fauna were high in spring and autumn, indicating typical pattern of temperate area. Out of dominant species, the brackish residence species such as Coilia nasus, Chelon haematocheilus, Mugil cephalus, Synechogobius hasta, Lophiogobius ocellicauda, Tridentiger barbatus, Palaeman carinicauda, Palaemon gravieri were collected almost year-round and predominated in abundance. Coastal migratory fauna species such as Coilia mystus, Thryssa hamiltonii, Thryssa adelae, Sardinella zunasi, Engraulis japonicus, Portunus trituberculatus, Acetes japonicus, Collichthys lucidus, Pampus argenteus were most plentiful from spring through autumn. Their adult coastal migratory entered the estuary in spring and large numbers of their juveniles were grew in summer and autumn until moving out to deeper waters for over-wintering, indicating they use estuary as nursing ground. Diadromous fish such as Anguila japonica adults were collected in autumn during their downstream migration. Brackish fauna and crustacean, especially shrimps were predominant, and few contaminant indicator species collected in the Han River estuary, indicating this area maintains the characteristics of natural estuary ecosystem.

서해 고군산군도 연안 낭장망 어획 수산생물의 종조성 및 주야 계절 변동

황선도 한국어류학회 1998 韓國魚類學會誌 Vol.10 No.2

1997년 4월부터 11월 사이에 전라북도 고군산군도 주변 해역에서 낭장망에 어획된 수산생물의 종조성과 계절에 따른 양적 변동을 파악하고, 계절별 낮·밤의 어획물 종조성 차이를 분석하였다. 조사기간 중 총75종이 출현하였으며, 이중 어류가 71%로 대부분을 차지하였고, 새우류 18%, 두족류 7%, 게류 4%이었다. 횐베도라치(Pholis fangi)가 전체 개체수의 44.3%, 멸치(Engraulis japonicus)가 42.8%로 이들 2종이 전체의 87.1%를 차지하였으며, 대부분이 치어나 유어 단계의 어린 개체이었다. 흰베도라치, 멸치, 까나리(Ammodyres personatus) 등은 연안에서 어린 시기를 보육장으로 이용하는데, 그 시기를 서로 달리하였다. 조사 해역에서 부유성 유어는 주·야간에 양적으로 유의한 차이가 있었다. To determine diel and seasonal variations in abundance and species composition of fishery resources, day and night samples were collected by a bag net from April through November 1997 off Kogunsan - gundo. A total of 75 species was collected. The total catch was consisted of 71% fish, 18% shrimps, 7% cephalopods and 4% crabs. Pholis fangi and Engraulis japonicus predominated, and accounted for 87% of the total number of fish collected. Most of them were larvae and juvniles. P. fangi and Ammodyres personatus occurred from April to June, and E. japonicus occurred from July to November, suggesting that they used the coastal areas as nursery ground at the different season to avoid competition. Dominant fish larvae and juveniles showed the significant diel difference in catch.
