Harmful algal blooms responsible for mass mortalities of marine organisms have been rare in Hokkaido, northern Japan, although fish-killing frequently reported from western Japanese coasts. In September-November 2021, a huge and prolonged cold-water bloom occurred along the Pacific coast eastern was associated with intensive sea urchin, fish, octopus, shellfish, etc. this study, morphology phylogeny dominant co-occurring unarmored dinoflagellates Kareniaceae were examined by using light...
In this work, the toxicity level of nano- and microparticles obtained by underwater welding was assessed. The evaluated on three types marine microalgae: Heterosigma akashiwo (Ochrophyta), Porphyridium purpureum (Rhodophyta), Attheya ussuriensis (Bacillariophyta). aim to study environmental risks associated with ingress micro- nanoparticles metal oxides into environment. Water samples containing suspensions from wet cutting processes were analyzed inductively coupled plasma mass spectrometry...
Forty-two different dinoflagellate cyst types were found in recent sediment samples collected between July 1999–September 2002 from 44 stations along the eastern coast of Russia. This represents first survey cysts Russian marine waters. Forty identified to species level, representing 17 genera. The most common those ellipsoidal Alexandrium spp., Protoceratium reticulatum, Gonyaulax spp. , Polykrikos kofoidii, P. schwartzii Protoperidinium americanum, minutum conicoides subinerme conicum and...
Abstract Preliminary studies on dinoflagellates epiphytic macrophytes in a bight of Peter the Great Bay, Sea Japan revealed presence two species genus Ostreopsis , O. cf. ovata and cf . siamensis Morphometric features, such as length pore plate, thecal ornamentations were used for identification. The differed from each other cell size plate. Cells smaller width, with dorsoventral diameter 36–60 μm width 24–45 μm, comparison cells which 63–78 36–54 width. are slightly flattened ; to...
Red tides and associated fisheries damage caused by the harmful raphidophyte Chattonella were reassessed based on documented local records for 50 years to understand distribution economic impacts of species in Western Pacific. Blooms with have been recorded East Asia since 1969, whereas they only Southeast 1980s. Occurrences from six Asian countries, Indonesia, Malaysia, Philippines, Singapore, Thailand Viet Nam, mass mortalities mainly farmed shrimp 1980–1990s, fish 2000–2010s. These...
Abstract Twenty-seven clones were established from elongate Alexandrium sp. cysts collected in six regions along the Russian Pacific coast. All isolates identified as tamarense via detailed epifluoresence microscopy of thecal plates. Morphological differences both cultured and wild cells study mainly occurred shape cell (length/width ratio), degree development sulcal list, posterior (S.p.) second antapical (2″″) Cells divided into two types: ‘short’ (isodiametrical or wide) ‘tall’. Each type...
Several studies in the Sea of Japan have dealt with taxonomy, morphology and ecology Chaetoceros species. In this study, a total 33 taxa was recorded between 1991 2004 from phytoplankton Peter Great Bay, northwestern part Japan. This investigation based on light electron microscopy. minimus is new record for Pacific Ocean, C. compressus var. hirtisetus seas Russia, socialis f. radians Diagnostic descriptions, illustrations distribution are provided all study area.
A survey focusing on species belonging to the diatom genus Pseudo-nitzschia was conducted in western North Pacific (the northwestern Sea of Japan and Okhotsk). Light electron microscopic examination 314 phytoplankton field samples collected from 1995 2006 revealed presence 11 species: P. americana, cf. caciantha, calliantha, delicatissima/arenysensis, fraudulenta, heimii, multiseries, multistriata, obtusa, pungens seriata. Detailed morphological descriptions illustrations as well...
Abstract Toxicity, morphology and distribution patterns of three bloom-forming species the diatom genus Pseudo-nitzschia (potential producers neurotoxin domoic acid causative organisms amnesic shellfish poisoning) from Peter Great Bay in northwestern Sea Japan are presented. calliantha , P. multistriata multiseries bloomed fall, with abundances exceeding 10 6 cells l -1 . This is first report toxicity Russian waters. Domoic was found stationary-phase (days 20–35) cultures isolated at...
For the first time presence of dinophysistoxin-1 (DTX-1) in a culture Prorocentrum foraminosum was revealed cells and medium. The clone isolated from coastal waters Sea Japan identified by molecular analyses SSU D1/D2 regions LSU rDNA. concentration DTX-1 8.4 ± 2.5 pg/cell and, cell-free media, 27.9 14.7 µg/L. toxin confirmed HPLC with high-resolution tandem mass-spectrometry.
