本研究旨在探讨2020年韩国国家公园金格基、三甲基和奈昌基水库的入侵物种--大鳞小翼鱼和大鳞细鳞鱼的影响。在Geumgyeji中，共采集到7科11种1221只，其中相对丰度为96.3%，长吻对虾为0.3%，主要食性为金龟子(37.2%)、蜻蜓(25.6%)、大翅目(11.6%)和大沙鼠(7.0%)。在Samgaji的调查结果中，共采集到854只，隶属于5科10种，其中以十足类(虾，33.6%)、蜻蜓(34.4%)、褐斑鱼(21.2%)和鸭嘴兽(6.1%)为主要食性。结果表明，该水域共采集到1,075尾，分属于7科1,075尾，分属于7科1,075尾，其中长足罗非鱼(77.5%)、双翅目(9.8%)、十足目(4.0%)和跳足类(21.2%)为主要食性，分属7科。金阁寺和桑加吉的沙鼠显然是在10多年前引入的。自引入沙门氏菌以来，鱼类数量迅速下降。20多年前引进的那江鸡，其相对丰度提高到40%。五到六年前引入了沙田鱼，自从引入沙田鱼后，鱼类种类和数量迅速下降。最后，我们讨论了国家公园中大银鱼和大银鱼的栖息状况和管理。
This study was conducted to elucidate the impact of invasive species, Micropterus salmoides and Lepomis macrochirus in Geumgyeji, Samgaji and Naejangji reservoirs of National Parks, Korea in 2020. In the Geumgyeji, 1,221 individuals of 11 species in 7 families were collected including M. salmoides (relative abundance, 96.3%) and L. macrochirus (0.3%), M. salmoides fed mainly on Rhinogobius brunneus (IRI, 37.2%), Odonata (25.6%), Megaloptera (11.6%), and M. salmoides (7.0%). In the results of Samgaji showed that 854 individuals of 10 species in 5 families were collected including M. salmoides (60.8%), and M. salmoides fed mainly on Decapoda (shrimp, 33.6%), Odonata (34.4%), R. brunneus (21.2%), and Zacco platypus (6.1%). In the Naejangji showed that 1,075 individuals of 13 species belonging to 7 families were collected including L. macrochirus (38.1%) and M. salmoides (9.5%), and L. macrochirus fed mainly on Branchiopoda (77.5%), Diptera (9.8%), Decapoda (4.0%) and M. salmoides fed mainly on R. brunneus (73.3%), Decapoda (21.2%). M. salmoides of Geumgyeji and Samgaji were apparently introduced more than a 10 years ago. The fish population declined rapidly since the introduction of M. salmoides. L. macrochirus of Naejangji was introduced more than 20 years ago, which increased its relative abundance to 40%. M. salmoides was introduced five to six years ago, and the fish species and population declined rapidly since the introduction of M. salmoides. Finally, we discussed the inhabitat status and management of M. salmoides and L. macrochirus in the National Park.
