This study investigated the fish fauna of Jeonjucheon and Samcheon Streams, flowing through the city of Jeonju, through surveys conducted at 10 sampling sites using kick net and cast net. The fish fauna collected included 10 families and 36 species, with a total of 2,064 individuals. Samcheon had 8 families and 30 species with 1,074 individuals, Jeonjucheon had 8 families and 26 species with 986 individuals. The dominant species was Zacco platypus with 1,202 individuals, and a total of 153 individuals of the subdominant were Pseudogobio esocinus. In Jeonjucheon Stream, a total of 567 individuals of the dominant species were collected as Z. platypus and 99 individuals of the subdominant species were collected as Pungtungia herzi, and there was no significant change in the stream environment except for the confluence site. Further expanded research covering the entire Jeonjucheon and Samcheon Streams region, accompanied by regular monitoring, is essential to record and understand fluctuations in fish fauna.

The goal of this study was to provide basic data necessary for managing fish in the Seomgang River by confirming diversity of fish species in the Seomgang River and determining the degree of change in fish species through a comparison with earlier related work. Growth rate, obesity level, and temporal and spatial reproductive capacities were analyzed to determine growth characteristics of dominant species. Fish fauna and structure of the fish community were surveyed at three different time points from October of 2020 to August of 2021 at eight sites. In addition, growth characteristics of Zacco platypus from June of 2021 to July of 2022 at four sites were determined. A total of 3,999 individuals, 43 species, and ten families of fish were identified. Among these species, 19 (44.19%) were Korean endemic species and four (9.30%) were endangered species. The dominant species was Z. platypus. Pungtungia herzi was identified as a subdominant species. An analysis of length-weight relationships and condition factor (k) of Z. platypus confirmed a good state of growth. As a result of a frequency analysis of the total length, the life cycle of the Z. platypus population living in the Seomgang River was found to be stable. According to gonadosomatic index (GSI) analysis, the spawning season of Z. platypus was estimated to occur after May, consistent with the literature.

섬은 내륙지역에 비해 상대적으로 외부간섭이 적어 생태계가 잘 보존된 생물다양성이 높은 지역으로 알려져 있다. 하지만 우리나라의 섬 지역의 생물다양성 연구는 일부 지역 또는 한정된 분류군에 국한되어 연구한 경우가 대부분이다. 곤충은 생물다양성 연구에 필수적인 분류군으로 국내에서는 전체 생물종 58,050종의 약35%인 20,274종이 알려져 있다(환경부 2022). 우리나라 섬의 곤충은 6,117종이 알려져 있으며, 대부분 제주도, 거제도, 진도 등 크기가 큰 섬에서 조사 및 연구가 이루어져 있다(국립호남권생물자원관 2022). 국립호남권생물자원관 에서는 섬 곤충다양성 연구를 위해 종목록 구축, 곤충상조사, DNA바코드 연구 등을 수행하고 있으며, 나비목 곡식좀나방상과의 신종·미기록종 발굴 및 계통분류학적 연구를 추진하고 있다. 본 발표를 통해 2021년부터 현재 까지의 주요 연구 추진방향 및 연구결과를 소개하고자 한다.

닭 사체를 이용하여 장소, 기온, 습도별 시식성 곤충상을 파악하기 위해 대전광역시 전민동 일대의 3개의 장소 를 선택하여 닭 사체별로 유인되는 곤충의 종류와 군집 상의 차이와 출현양상을 조사하였다. 이를 위해, 닭 사체에 유인되는 곤충을 주기적으로 채집하고 해당 일자의 온도와 습도를 조사하여 기록했으며, 채집한 곤충들은 외부 형태적 특징으로 분류하고 개체수를 확인했다. 조사결과, 딱정벌레목과 파리목의 개체가 가장 많았고, 그 외에 바퀴목, 벌목, 노린재목 분류군에 속하는 다양한 곤충들이 유인된 것을 확인할 수 있었다. 본 연구 결과는 법곤충 시식성 곤충을 연구하는데 중요한 기초자료로 활용될 수 있도록 결과를 종합정리하였다.

On April 29, 2021 (1st), June 2 (2nd), and August 17 (3rd), we surveyed benthic macroinvertebrates fauna at Muljangori-oreum wetland in Bonggae-dong, Jeju Island, Korea. Muljangori-oreum wetland was divided into four areas. The survey was conducted in three accessible areas (areas 1-3). As a result of habitat environment analysis, the average monthly temperature from 2017 to 2021 was the highest in July and August and the lowest in December and February. This pattern was repeated. As a result of analyzing changes in vegetation and water surface area through satellite images, normalized difference vegetation index (NDVI) increased from February to July and decreased after July. Normalized difference water index (NDWI) was analyzed to show an inverse relationship. A total of 21 species from 13 families were identified in the qualitative survey and a total of 412 individuals of 24 species from 15 families were identified in the quantitative survey. A total of 26 species from 17 families, 8 orders, 3 classes, and 2 phyla of benthic macroinvertebrates were identified. The dominant species was Chronomidae spp. with 132 individuals (32.04%). Noterus japonicus was a subdominant species with 71 individuals (17.23%). As a result of comparative analysis of species identified in this study and the literature, it was confirmed that species diversity was high for Coleoptera and Odonata. Main functional feeding groups (FFGs) were found to be predators. Habitat orientation groups (HOGs) were found to be swimmers. In OHC (Odonata, Hemiptera, and Coleoptera) group, 17 species (73.91%) in 2021, 23 species (79.31%) in 2016, 26 species (86.67%) in 2018, and 19 species (79.17%) in 2019 were identified. Cybister japonicus, an endangered species II, was confirmed to inhabit Muljangori-oreum wetland in the literature. Ten individuals (2.43%) were also confirmed to inhabit Muljangori-oreum wetland in 2021. Therefore, continuous management and habitat protection are required to maintain the habitat environment of C. japonicus in Muljangori-oreum wetland.

Paddy fields are important habitats for maintaining the biodiversity of agricultural ecosystems. Recently, as the need for safe food and biodiversity conservation has increased, the rice cultivation methods have undergone changes. This study was conducted to investigate the fish fauna in Environmentally Friendly Paddy fields (EFP) and Conventional Paddy fields (CP), and compare the characteristics of Misgurnus anguillicaudatus and Aphyocypris chinensis populations in EFP and CP. A total of 2,703 fish were collected and classified into six families and 13 species. Our results showed that there was a difference in the proportion of fish populations in the two paddy fields, and the number of individuals in EFP was higher than in CP. The weight values of M. anguillicaudatus were higher in EFP than in CP, and the total length, body length, and weight values of A. chinensis were higher in EFP than in CP. Conditional factor (K) values also showed similar trends in EFP and CP. Our results indicate that the farming practices in paddy fields have a significant effect on the characteristics of M. anguillicaudatus and A. chinensis populations, and the results of this study can be used as basic data for securing biodiversity in future agricultural ecosystems.
