  • We analyzed research topics, temporal distribution of field sites, and researcher network of 1,508 limnology publications in the Korean Journal of Limnology (1968~2012) and the Korean Journal of Ecology and Environment (2013~2017). We found that water quality and sediment, phytoplankton, invertebrates, and fish were major subjects during the study periods. Survey of flora and fauna and physiological experiment of freshwater species were the largest subjects during 1970~80s, while other subjects including production, behavior, modeling, and ecological assessment have been rapidly increased since the 1990s. Most of the biological taxa equally studied lotic and lentic system, however, invertebrates and fish related studies more focused on the lotic system. Spatially, the field site of Korean limnology studies was found to be concentrated in main river channels runs through urban areas and artificial lakes than preserved natural areas. Freshwater system, located at the elevation range of 301~400 m (upstream of main channels), had the lowest number of field sites. Collaboration among researchers and different institution types have been steadily increased and expanded as the number of publications increased.

  • 식생활패턴변화와 국민보건적 요구도가 증가함에 따라 수산물 및 청정채소에 대한 요구가 급증하고 있어 내수면양어시설과 수경재배시설이 증가하고 있는 추세이다 한편 석유에너지의 사용에 따른 환경오염문제가 대두되고 있으며 또한 난방연료가격앙등에 의한 생산비상승으로 고심하고 있는 실정이다. (중략)

  • 황해는 얕은 수심, 강한 조류, 다량의 육수유입 그리고 다양한 수괴의 존재로 특징지워 지는 해역으로 생산력이 매우 높은 곳이다. 그러나 육상 오염원의 증가, 간척지 개발, 남획 등 여러 가지 요인에 의해서 어획량의 감소 및 종 조성의 변화 등이 나타나고 있다. 이 같은 악화 상태에 있는 해양생물 자원을 육성ㆍ관리하기 위해서는 생태계적 측면에서 접근하여야 할 것이다. (중략)

  • Studying on the shirpms produced out of the freshwater in Nam-hae Island , the four kinds of them were found as follows : 1. Paratya compressa (De Haan) 2. Neocaridina denticulata (De Haan) 3. Neocaridina denticulata koreana Kubo 4. Caridina leucostica Stimposon Among the said kinds of them, Paratya compressa and Caridina leucostica are to be listed for the first time in Korean shrimps fauna, and at the same time, Neocaridina denticulata and Neocaridina denticulata koreana were found distributed mostly in whole the rivers, lakes and ponds of this area.
