Abstract
To investigate the presence of Anadara kagoshimensis and Tegillarca granosa 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 ofmonthly sampling in June, July, and September with a three or four days interval sampling in August). The samples were analyzed using metagenomic next-generation sequencing methods (target gene: mitochondria COI region). In this study, a total of 21 bivalve OTUs were detected with the most abundant bivalve OTUs (relative mean abundance > 1%) belonging to Crassostrea sikamea, Xenostrobus atratus, Musculista senhousia, Crassostrea gigas, Sinonovacula constricta, A. kagoshimensis, Kurtiella aff. Bidentate, and T. granosa. In particular, A. kagoshimensis and T. granosa (the main fisheries resources on the Boseong coast) accounted for 0.51-12.5%(average 4.00%) and 0.01-12.50%(1.92%), respectively. The planktonic bivalve larvae were most abundant from July to August. A. kagoshimensis was most abundant in early August, but rare in the other investigated periods, while T. granosa was more abundant in late August. The bivalve larvae monitoring is important to predict the production of bivalve fisheries and intensive monitoring is needed to understand changes in planktonic bivalve larvae because potentially rapid turnover can respond to the ecological interaction of spawning bivalves.
