dc.description.abstract To investigate the temporal distribution of planktonic larvae of Tegillarca granosa and Anadara kagoshimensis in the Boseong coastal waters of South Korea, samples of planktonic bivalve larvae were taken from the coastal waters from June to September 2018 (this consisted of monthly sampling in June, July, and September with three- or four-day interval sampling in August). The samples were analyzed using metagenomic next-generation sequencing methods (target gene: mitochondria cytochrome c oxidase 1 region). In this study, a total of 21 bivalve operational taxonomic units (OTUs) were detected with the most abundant bivalve OTUs (relative mean abundance >1%) belonging to Magallana sikamea, Xenostrobus atratus, Musculista senhousia, Magallana gigas, Sinonovacula constricta, Anadara kagoshimensis, Kurtiella aff. bidentata, and Tegillarca granosa. In particular, Tegillarca granosa and Anadara kagoshimensis (the main fishery resources on the Boseong coast) accounted for 0.51-12.50% (average 4.00%) and 0.01-12.50% (1.92%), respectively. The planktonic bivalve larvae were most abundant from July to August. Anadara kagoshimensis was most abundant in early August but rare in the other investigated periods, whereas Tegillarca granosa was more abundant in late August. Bivalve larvae monitoring is important to predict the production of bivalve fisheries. Therefore, intensive monitoring is needed to understand the changes in planktonic bivalve larvae because potentially rapid turnover can respond to the ecological interaction of spawning bivalves. 이매패류의 부유유생은 성패(양식자원)에 직접적인 영향을 미치고 있어, 부유유생의 출현시기 및 출현량에 관한 연구는 자연 채묘량의 증대와 인공종묘의 생산을 위해서 매우 중요하다. 이에 본 연구에서는 유전자 분석기법을 이용하여 보성 연안에서 총 21종의 이매패류 부유유생을 확인하였으며, 이 중 구마모토굴(M. sikamea), 왜홍합(X. atratus), 종밋(M. senhousia), 참굴(M. gigas), 가리맛조개(S. constricta), 새꼬막(A. kagoshimensis), Kurtiella aff. bidentata 그리고 꼬막(T. granosa)이 중요 부유유생으로 관찰되었다. 특히, 보성 연안해역의 주요 수산자원인 새꼬막(A. kagoshimensis)과 꼬막(T. granosa)은 각각 이매패류의 0.51~12.50% (평균 4.00%), 0.01~12.50% (평균 1.92%)의 구성비율을 차지하며 다른 이매패류보다 낮은 출현량을 보였다. 꼬막(T. granosa)과 새꼬막(A. kagoshimensis)의 부유유생은 6월부터 9월까지 관찰되었으나, 각각 8월 초와 8월말에 가장 높은 출현율을 보였다. -
