Harmful Algal Blooms (HABs) can lead to fishery closures when toxin levels in commercial species exceed regulatory thresholds. Domoic acid (DA), the neurotoxin causing Amnesic Shellfish Poisoning (ASP), is particularly persistent king scallops (Pecten maximus), a commercially valuable France. This known for its slow depuration rate compared other species. As result, anticipating DA dynamics therefore key managing openings autumn, especially following spring contamination events. study used...
Effective nursery diets can greatly reduce the cost of producing juvenile sea cucumbers for release to aquaculture or restocking programs. However, methods systematically testing bioavailability artificial diet ingredients are poorly developed, and consequently, there has been little research in this field. The current study presents developed test suitability common carbohydrate protein sources inclusion Australostichopus mollis . Apparent digestibility carbohydrates was moderate did not...
A new species belonging to the toxin producing diatom genus Pseudo-nitzschia, P. hallegraeffii sp. nov., is delineated and described from East Australian Current (EAC). Clonal cultures were established by single cell isolation phytoplankton net hauls collected as part of a research expedition in EAC region 2016 on RV Investigator. Cultures assessed for their morphological genetic characteristics, sexual compatibility with other Pseudo-nitzschia species, ability produce domoic acid. Light...
The impact of an alien species is correlated with its abundance and potential to colonise new environments. Consequently, the crucial aspects that give a mytilid invasive include strength capacity for adhesion wide variety substrates ecological tolerance environmental conditions. black pygmy mussel Xenostrobus securis settles together indigenous raft cultured Mytilus galloprovincialis on hard inner coastline Ría de Vigo (Atlantic Coast NW Spain). Key parameters success these could their...
SUMMARY Certain species of the marine diatom genus Pseudo‐nitzschia are responsible for production domoic acid (DA), a neurotoxin that can bioaccumulate in food chain and cause amnesic shellfish poisoning (ASP) animals humans. This study extends our knowledge by reporting on first observation potentially toxic simulans from this region. One clonal strain P. was isolated East Australian Current characterized using light transmission electron microscopy, phylogenetic analyses based regions...
Abstract Phytoplankton-bacteria interactions are governed by the transformation of algal-derived organic matter, exchange metabolites and infochemicals. However, assembly bacterial community within phycosphere is not well understood. In this study, we performed experiments to tease apart role species-specific exometabolites, bacterial/bacterial algal/bacterial in shaping phycophere. Twelve isolates, representative main members microbiome were selected exposed phytoplankton extracellular...
