Harmful blooms of the dinoflagellate Cochlodinium polykrikoides (Margalefidinium polykrikoides) had detrimental aquacultural and economic effects globally, to reduce damage caused by these blooms, early biomonitoring quantitative analysis C. are utmost importance. Here, for detection using real-time polymerase chain reactions, we developed specific primers targeting large subunit ribosomal DNA (LSU rDNA) evaluated their applicability in field during occurrence a bloom. The not only...
Marine organisms produce sounds for various purposes, including spawning, avoidance, and migration, with each species exhibiting unique acoustic characteristics. This study observed the grunt of Pacific cod (Gadus macrocephalus) during spawning season first time using passive monitoring (PAM) techniques. Acoustic signals were recorded continuously about one month at an aquaculture fish farm in Korea. From these recordings, 1208 extracted automatic detector, statistical time–frequency...
Marine organisms make sounds for various reasons, including spawning and avoidance, which are species-specific. Traditionally, Korean fishermen in the northwest Pacific Ocean have listened to locate grounds of Brown croaker (Miichthys miiuy), one important commercial fish species. We measured recorded October, croakers’ season (August October). The mean signal duration with standard deviation was 0.184 ± 0.027 s, pulse interval 0.022 0.001 s. zero-to-peak sound pressure level 165.2 0.7 dB....
To analyze variations in the vertical distribution of water temperatures and impact advection central Yellow Sea, multi-layer temperature current observations were conducted from 31 May to 8 June 2021. Water exhibited a typical three-layer summer structure, with uniform deep-layer averaging 8.23 ± 0.05 °C. The field was dominated by northeast–southwest tidal currents, but residual characteristics indicated that non-tidal components significantly influenced circulation. changes lagged about 3...
통영 연안 해역에서 chlorophyll-a 농도 변화 패턴과 그에 따른 식물플랑크톤 군집 변동을 파악하기 위해 62일간 연속 관측(2017년 7월 29일~9월 28일) 및 주 1~2회의 주기적인 분석을 실시하였다. 조사기간 동안 농도가 증감하는 변화가 3회 발생하였다. 첫 번째 변화(8월 6일~14일)에서는 14~16시 급격한 증가가 반복적으로 나타났으며, 이는 중 최우점종으로 출현한 와편모조류 Alexandrium affine의 일주수직운동에 의한 결과이다. 두 번째(8월 24일~30일) 세 번째(9월 12일~17일) 변화는 Chaetoceros curvisetus, Skeletonema marinoi-dohrnii complex등의 규조류에 의해 증가하였으며, 이때 규조류는 event 1의 A. 14~16시에 증가와 달리 특정 시간에 관계없이 증가하였다. 또한 실시간 농도의 관측을 통해 일주수직운동 특징적인 양상을 찾아냈으며, 3회의 농도에 대한 7~12일의 간격을 두고
