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 ...

Inhibition Equivalency Factors for Dinophysistoxin‑1 and Dinophysistoxin‑2 in Protein Phosphatase Assays: Applicability to the Analysis of Shellfish Samples and Comparison with LC-MS/MS

, 2016
The protein phosphatase inhibition assay (PPIA) is a well-known strategy for the determination of diarrheic shellfish poisoning (DSP) lipophilic toxins, which deserves better characterization and understanding to be used as a routine screening tool in ...

Sublethal doses of dinophysistoxin-1 and okadaic acid stimulate secretion of inflammatory factors on innate immune cells: Negative health consequences [PDF]

, 2017
© 2016 Elsevier LtdOne of the proposed mechanisms to explain why Diarrhetic Shellfish Poison (DSP) toxins are tumor promoters is founded on the capacity of these toxins to increase TNF-α secretion.

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.

Clarification of the C-35 Stereochemistries of Dinophysistoxin-1 and Dinophysistoxin-2 and Its Consequences for Binding to Protein Phosphatase

, 2016
Okadaic acid analogues are well known as protein phosphatase inhibitors and occur naturally in marine shellfish feeding on dinoflagellates of the genus Dinophysis, leading to diarrhetic shellfish poisoning of shellfish consumers. Knowledge of the correct

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 ...
