Combined effects of a simulated marine heatwave and an algal toxin on a tropical marine aquaculture fish cobia (Rachycentron canadum)

Aquaculture Research, Volume 51, Issue 6, Page 2535-2544, June 2020., 2020
Abstract Ongoing global warming is one of the major challenges for the development of aquaculture in the tropical regions where species are already cultured in the water temperature close to their upper physiological thresholds. Furthermore, warming can trigger blooms of toxic algae, yet we do not know how extreme warming such as a marine heatwave (MHW)

Effect of temperature on production of okadaic acid, dinophysistoxin-1, and pectenotoxin-2 by Dinophysis acuminata in culture experiments [PDF]

Aquatic Microbial Ecology, 2010
We cultivated Dinophysis acuminata, a mixotrophic dinoflagellate causing diarrhetic shellfish poisoning worldwide, at different temperatures by providing a mixotrophic ciliate Myri- onecta rubra as a food source. We examined the effects of temperature on growth rates and moni- tored production of the toxins okadaic acid (OA), dinophysistoxin-1 (DTX1 ...

Dinophysis acuta in Scottish Coastal Waters and Its Influence on Diarrhetic Shellfish Toxin Profiles

Toxins, 2018
Diarrhetic shellfish toxins produced by the dinoflagellate genus Dinophysis are a major problem for the shellfish industry worldwide. Separate species of the genus have been associated with the production of different analogues of the okadaic acid group ...

First Detection and Seasonal Variation of Lipophilic Toxins Okadaic Acid, Dinophysistoxin-1, and Yessotoxin in Korean Gastropods

Journal of Food Protection, 2012
Okadaic acid (OA), dinophysistoxin-1 (DTX1), pectenotoxin-2, and yessotoxin (YTX) are classes of lipophilic toxins found in marine animals. OA and DTX1 accumulation causes diarrhetic shellfish poisoning, a worldwide public health problem. Diarrhetic shellfish poisoning has not previously been reported in gastropods, which are widely consumed in Korea.

First report of diarrheic shellfish toxins in mollusks from Buenos Aires Province (Argentina) associated with Dinophysis spp.: evidence of okadaic acid, dinophysistoxin-1 and their Acyl-derivatives

Boletín de la Sociedad Argentina de Botánica
 In January 2010, the toxin-producing dinoflagellates Dinophysis acuminata and D. caudata (103 cells·l-1) were detected in Mar Azul during routine plankton monitoring in Buenos Aires Province  coastal waters, Argentina.

Toxicity and Growth Assessments of Three Thermophilic Benthic Dinoflagellates (Ostreopsis cf. ovata, Prorocentrum lima and Coolia monotis) Developing in the Southern Mediterranean Basin

Toxins, 2016
Harmful benthic dinoflagellates, usually developing in tropical areas, are expanding to temperate ecosystems facing water warming. Reports on harmful benthic species are particularly scarce in the Southern Mediterranean Sea.

A Screening Tool for the Direct Analysis of Marine and Freshwater Phycotoxins in Organic SPATT Extracts from the Chesapeake Bay

Toxins, 2020
Many detection methods for phycotoxins, bioactive compounds produced by harmful algae, focus on one compound or a class of related compounds. Multiple harmful algal species often co-occur in the environment, however, emphasizing the need to analyze for ...

Improved Isolation Procedures for Okadaic Acid Group Toxins from Shellfish (Mytilus edulis) and Microalgae (Prorocentrum lima)

Marine Drugs, 2020
Okadaic acid (OA) group toxins may accumulate in shellfish and can result in diarrhetic shellfish poisoning when consumed by humans, and are therefore regulated.

Safety of oil from Schizochytrium sp. A2 for use in infant and follow‐on formula as a novel food pursuant to regulation (EU) 2015/2283

EFSA Journal, Volume 24, Issue 5, May 2026.
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‐like organism Schizochytrium sp. A2 as a novel food (NF) pursuant to Regulation (EU) 2015/2283.
