Grazer‐induced bioluminescence and toxicity in marine dinoflagellates

Limnology and Oceanography, Volume 70, Issue 12, Page 3769-3783, December 2025.
Abstract Marine copepods are the most abundant multicellular zooplankton in the global oceans. They imprint their surrounding waters with a unique bouquet of chemical compounds, including polar lipids such as copepodamides. Prey organisms can detect copepodamides and respond by inducing defensive traits including bioluminescence, toxin production ...

Oceanography and Pacific Oyster Biochemical Composition in a Novel Oyster‐Growing Region

Aquaculture, Fish and Fisheries, Volume 5, Issue 5, October 2025.
ABSTRACT The farming of Pacific oysters (Crassostrea [Magallana] gigas) is a rapidly growing industry in Alaska, where farms represent some of the highest latitude oyster cultivation efforts in the world. Little is known about the nearshore oceanography where Alaskan farms are located, or how the subarctic marine context influences oyster tissue ...

Safety of oil from Schizochytrium limacinum (strain ATCC‐20889) for use in infant and follow‐on formula as a novel food pursuant to Regulation (EU) 2015/2283

EFSA Journal, Volume 23, Issue 1, January 2025.
Abstract Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on the safety of an oil derived from the microalga Schizochytrium sp. (strain ATCC‐20889) as a novel food (NF) pursuant to Regulation (EU) 2015/2283.

Risks for public health related to the presence of tetrodotoxin (TTX) and TTX analogues in marine bivalves and gastropods

EFSA Journal, Volume 15, Issue 4, April 2017., 2017
Abstract Tetrodotoxin (TTX) and its analogues are produced by marine bacteria and have been detected in marine bivalves and gastropods from European waters. The European Commission asked EFSA for a scientific opinion on the risks to public health related to the presence of TTX and TTX analogues in marine bivalves and gastropods.

Diarrhetic shellfish toxins production appears to be driven by photosynthesis and phosphate–revealed by different light-adapted strains of Prorocentrum lima complex and P. caipirignum

Frontiers in Marine Science, 2023
IntroductionDiarrhetic shellfish toxins (DST) harm shellfish aquaculture and endanger human health, and include well-known marine dinoflagellate-produced toxins such as okadaic acid (OA) and analogues, such as dinophysistoxin-1 (DTX-1).

Sublethal exposure of eastern oyster Crassostrea virginica to the goniodomin‐producing dinoflagellate Alexandrium monilatum: Fate of toxins, histopathology, and gene expression

Journal of Aquatic Animal Health, Volume 36, Issue 4, Page 374-394, December 2024.
Abstract Objective The dinoflagellate Alexandrium monilatum forms blooms during summer in tributaries of the lower Chesapeake Bay. Questions persist about the potential for A. monilatum to negatively affect aquatic organisms. Its main toxin, goniodomin A (GDA), a polyketide macrolide, has been shown to have adverse effects on animals, for example ...

Prey morphotype and abundance controls plastid retention and bloom dynamics for a mixotrophic dinoflagellate

Limnology and Oceanography, Volume 69, Issue 11, Page 2732-2747, November 2024.
Abstract Dinophysis is an obligate mixotroph that relies on consumption of the ciliate, Mesodinium rubrum, to grow and form harmful algal blooms (HABs). In this study, blooms of Dinophysis acuminata in two NY, USA, estuaries were studied over the course of 3 yr (2019–2021) using discrete samples and an Imaging FlowCytobot (IFCB) to capture images of ...
