Although soft tunic syndrome (STS) in the ascidian is a serious disease, helpful measures have yet not been established. It was examined this study by applying aniti-parasitic drugs to eradicate causative protozoa Azumiobodo hoyamushi from infected ascidians. Formalin synergistic killing parasites vitro when co-treated with hydrogen peroxide (H2O2) or bronopol, but chloramine-T povidone-iodine (PVP-I), tested parasite culture. The effects did change formalin-H2O2 (or bronopol) ratios were...
Abstract The effects of thermal stress on antioxidant defences in tissues the Antarctic clam Laternula elliptica were evaluated and activities some enzymes, levels total glutathione (GSH) protein carbonyl (PC) digestive gland gill over 0–4 days under extreme (10°C) measured. Superoxide dismutase activity was slightly higher after one day stress, although catalase not altered significantly either or tissues. Thermal associated with a significant increase GSH-related enzymes. Glutathione...
Interannual variation of Perkinsus olseni infection intensity in the adult Manila clam Ruditapes philippinarum Gomso Bay, off west coast Korea, was monitored from 1999 to 2000. Infection P. (i.e., total number cells unit tissue weight) determined using Ray's fluid thioglycollate medium assay and Choi's 2-M NaOH digestion. In monthly prevalence ranged 83 (April 2000)–100%. It remarkable that 18 mo sampling, remained at 100 % 12 sampling months. 366,001 (July 1999)–2,235,325 cells/g wet...
Oyster aquaculture is one of the fastest-growing food production industries worldwide; however, it faces a significant challenge from protist Perkinsus marinus, particularly in USA. Although several quantitative molecular diagnostic methodologies are available for identifying diseases caused by P. primer pairs used therein led to non-specific identification other spp. Hence, real-time PCR (Pm-qPCR) assay specific marinus was developed using TaqMan-based probe with internal quencher this...
The annual reproductive cycle of the Indo-Pacific tellinid clam Heteromacoma irus (Hanley, 1845) was investigated, using histology, for first time in this study. sex ratio H. collected from a rocky intertidal area on northern coast Jeju Island, Korea, found to be 1:1, indicating that is gonochoric. In January, most clams were resting phase, although small number females showed oogonia their follicular epithelium. From February May, oocyte diameter increased rapidly, and fully mature eggs...
The occurrence of 'algal bloom', caused by the mass proliferation phytoplankton, causes serious problems in streams and lakes Korea. Therefore, this study, phytoplankton filter-feeding trait Unio douglasiae, a type freshwater clam, was used to reduce algal bloom outdoor water tanks during summer. This involved construction U. douglasiae cultivation apparatus, wherein 1,000 clams were divided into 8 rectangular baskets arranged shape an empty square. control tank manufactured exactly same...
Abstract Background Perkinsosis is a major disease affecting the commercially important marine mollusk Ruditapes philippinarum (Manila clam) in Asian waters. In this study, we investigated morphological characteristics of Perkinsus olseni , causative agent perkinsosis, cultured under laboratory conditions at different stages its life cycle using scanning electron microscope (SEM). Results The prezoosporangia formed after induction with Ray’s fluid thioglycollate medium (RFTM) developed into...
