DO, COD, DIN 및 PO$_{4}$ $^{3}$ -P은 각각 평균 7.11 mg/L, 0.44 mg/L, 4.55$mu extrm{g}$ -at./L 및 0.36$mu extrm{g}$ -at./L이었다. 표층퇴적물의 입도조성은 사력질, 니사질, 사니질 등으로 다양하게 나타났으며, 퇴적물의 IL, COD 및 AVS는 각각 평균 2.6%, 13.70 mg/g dry 및 0.33 mg/g dry였다. 한편, 식물플랑크톤의 현존량은 90.3(9월)-1,272.0 cell/ml(2월)이었으며, 우점종은 Skeletonema costatum, Paralia sulcata, Eucampia zodiacus, Chaetoceros curvicetus, Chaetoceros affinis, Chaetoceros debilis, Chaetoceros decipiens, Asterionella glacialis, Pseudo-nitzschia longissima, Pseudonitzschia seriata, Ceratium furca, Ceratium fusus 등이었다. 벗굴 서식지에서 출현한 조개류는 벗굴(Ostrea denselamellosa), 참굴(Crassostrea gigas), 바지락(Tapes philippinarum), 새고막(Scaphaca subcrenata), 피조개(Scaphaca broughtonii), 키조개(Atrina pectinata), 새조개(Fulvia mutica), 진주담치(Mytilus edulis), 살조개(Protothaca jedoensis), 갈색이랑조개(Megacardita ferruginosa) 등 모두 10종이었다. 그리고 이매패류의 평균 자원량은 21개체/$m^2$ (479.14 g/$m^2$ )이었고, 벗굴은 0.25 개체/$m^2$ (231.25 g/$m^2$ )로 나타났다.양문호,한창희,김형섭,최상덕 한국패류학회 상세보기 새조개 (Fulvia mutica) 의 Microsatellite Markers 개발을 위한 차세대 염기서열 분석법의 활용 This study aimed to utilize next-generation sequencing for developing microsatellite markers in Fulvia mutica. The Illumina NovaSeq 6000 System generated a total of 327,584,690 reads, resulting in a sequence length of 49,465,288,190 bp. The de novo assembly yielded an 885 Mb (885,020,821 bp) sequence. In this context, 675,057 contigs longer than 500 bp were identified. Among these, 107,985 contigs containing microsatellite regions were identified, accounting for 15.9%. A total of 105,632 microsatellite loci were found within these 107,985 microsatellite regions. Among these loci, polymorphism information was confirmed at 3,723 (3.5%) microsatellite marker positions. eighty-two primer sets were designed based on the 150 microsatellite loci. As a result, 14 microsatellite loci were selected for estimating population genetic parameters in both wild populations. The mean number of effective alleles was 11, ranging from 7 to 18. The observed heterozygosity (HO) ranged from 0.615 to 0.937, with an average of 0.790, while the expected heterozygosity (HE) ranged from 0.629 to 0.924, also with an average of 0.790. Based on these findings, the compiled panel of 14 microsatellite markers is anticipated to facilitate examining genetic traits within the Fulvia mutica population in Korea. The results of the analysis of genetic diversity and gene relationships in Fulvia mutica are expected to be crucial data for the management, conservation, and sustainable utilization of genetic resources. Such information is expected to play a pivotal role in developing conservation and management strategies and formulating policies and strategies for sustainable utilization of genetic resources. 동춘매,노은수,이미난,김우진,김영옥,김은미 한국패류학회 상세보기 새조개, Fulvia mutica 치패의 저질잠입특성 This study investigated the characteristics of sediment immersion activity in order to utilize them as a basis for suitable site selection when releasing cockle, Fulvia mutica spat. The cockle, F. mutica spat were spawned from natural broodstock in April, and the cockle spat (shell length 17.96 ± 4.78 mm) were reared in a 2 ton FRP square tank (300 × 100 × 70 cm) for 185 days in a flow-through system. To investigate the sediment immersion activity characteristics, 30 were placed in each sediment grain size of fine sand (0.12 ± 0.03 mm), medium sand (0.93 ± 0.24 mm) and coarse sand (2.69 ± 0.67 mm), and the immersion rate and immersion time of each individual spat were investigated. As a result, the in rate of each 10-20 mm cockle spat was more than 90% within 60 minutes except for the coarse sand, and the immersion time was more than twice as long. 이시우,김위식,김정,이덕찬,김소희 한국패류학회 상세보기 새조개 (Fulvia mutica) 난 발생 및 유생 성장에 미치는 수온의 영향 The effect of water temperature on spawning induction, larval development, spat settling and its growth of the cockle shell, Fulvia mutica, were investigated to obtain the basic data for effective seed production. The eggs, which were randomly divided into 6 groups of water temperatures of 14, 17, 20, 23, 26 and 29°C, were transferred into 1 L beaker, respectively. The relationships between the water temperature and the required time (1/h, hour) by each egg developmental stage were calculated. Biological minimum water temperature and the cumulative water temperature until egg development of the veliger stage were calculated to be 0.1°C and 397.3°C, respectively. The optimal water temperature for developmental bioassay of F. mutica was clarified to be 23°C. The required time for the embryo to become veliger larvae was 20 hours at 23°C. 김재민,김상철,허준욱,임상민,김영훈,선승천,강경호 한국패류학회 상세보기
