Title

Seasonal occurrence characteristics of Aidanosagitta crassa morphotypes in coastal waters of Korea

Abstract

Aidanosagitta crassa, a key species in South Korea’s coastal waters, exhibits three morphological types: Type C with a collarette-containing trunk, Type N lacking a collarette, and an intermediate Type I. Limited research studies have been conducted on their ecological patterns, prompting this study to elucidate seasonal occurrence patterns of A. crassa types in Pyeongtaek. Field surveys at six stations in Pyeongtaek port were conducted in winter (Feb.), spring (May), summer (Aug.), and autumn (Nov.) of 2010. Water temperature and salinity were measured and zooplankton samples were collected for abundance analysis. Type C predominated in winter and autumn. Type I predominated in summer and Type N predominated in summer and autumn. Occurrence patterns were influenced by water temperature. Type C showed a negative correlation with water temperature. Type N was positively correlated with water temperature. However, Type I showed no significant correlation with water temperature. In 2013, genetic sampling using the mtCOI marker was conducted in winter and summer. Despite morphological differences, genetic analysis revealed intraspecific diversity due to seasonal environmental changes.
