Abstract

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.

본 연구는 국립공원 내 생태계교란 어종 배스와 블루길의 도입에 따른 영향을 파악하기 위해 2020년 금계지, 삼가지, 내장지에서 조사를 실시하였다. 금계지에서는 7과 11종 1,221개체가 채집되었고, 배스는 우점종(96.3%), 블루길은 소수(0.3%) 서식하고 있었고, 배스는 주로 밀어(IRI, 37.2%)와 잠자리목(25.6%), 뱀잠자리목(11.6%), 배스(7.0%) 등을 섭식하였다. 삼가지에서는 5과 10종 854개체가 채집되었고, 배스는 우점종(60.8%)으로 주로 새우류(33.6%)와 잠자리목(34.4%), 밀어(21.2%), 피라미(6.1%) 등을 섭식하였다. 내장지에서는 7과 13종 1,075개체가 채집되었고, 블루길은 우점종(38.1%), 배스는 우세종(9.5%)으로 나타났으며, 블루길은 주로 물벼룩류(IRI, 77.5%)와 파리목(9.8%), 새우류(4.0%) 등을 섭식하였고 배스는 주로 밀어(73.3%)와 새우류(21.2%) 등을 섭식하였다. 금계지와 삼가지의 배스는 10여 년 전에 도입된 것으로 추정되고, 도입 이후 대부분의 어류는 개체수가 급격히 감소하였다. 내장지의 블루길은 20여 년 전에 도입된 것으로 추정되며, 도입 이후 상대풍부도가 점점 증가하여 40%대에 도달하였고, 배스는 5~6년 전에 도입되었고 도입 이후 자생 어류의 종수와 개체수가 급격히 감소하였다. 마지막으로 국립공원 내 배스와 블루길의 서식현황 및 관리방안에 대해서 논의하였다.
