Tetrodotoxin and Its Analogues in the Pufferfish Arothron hispidus and A. nigropunctatus from the Solomon Islands: A Comparison of Their Toxin Profiles with the Same Species from Okinawa, Japan

Toxins, 2015
Pufferfish poisoning has not been well documented in the South Pacific, although fish and other seafood are sources of protein in these island nations. In this study, tetrodotoxin (TTX) and its analogues in each organ of the pufferfish Arothron hispidus ...

Survey of Tetrodotoxin in New Zealand Bivalve Molluscan Shellfish over a 16-Month Period

Toxins, 2020
Tetrodotoxin (TTX) is a heat-stable neurotoxin typically associated with pufferfish intoxications. It has also been detected in shellfish from Japan, the United Kingdom, Greece, China, Italy, the Netherlands and New Zealand. A recent European Food Safety

Cyanotoxins: methods and approaches for their analysis and detection [PDF]

, 2017
Cyanotoxins are secondary metabolites produced by cyanobacteria, a group of photosynthetic prokaryota especially found in freshwater. In favourable conditions (i.e. high nutrient levels, light intensity, water temperature), cyanobacteria can form blooms,

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 ...

The Role of Heterocysts in Cyanotoxin Production during Nitrogen Limitation

Toxins, 2023
Cyanobacteria harmful algal blooms (cyanoHABs) can have impacts on human health, aquatic ecosystems, and the economy. Nutrient management is an important mitigation and even remediation strategy.

Successful isolation and cultivation of Cylindrospermopsis raciborskii strains isolated from finished drinking water samples [PDF]

, 2019
This work presents the successful establishment of Cylindrospermosis raciborskii cultures isolated from water samples collected at the exit point of Water Treatment Plant (WTP). An intense bloom dominated by filamentous cyanobacteria (Aphanizomenon spp.,

Neurotoxic Alkaloids: Saxitoxin and Its Analogs [PDF]

Marine Drugs, 2010
Saxitoxin (STX) and its 57 analogs are a broad group of natural neurotoxic alkaloids, commonly known as the paralytic shellfish toxins (PSTs). PSTs are the causative agents of paralytic shellfish poisoning (PSP) and are mostly associated with marine dinoflagellates (eukaryotes) and freshwater cyanobacteria (prokaryotes), which form extensive blooms ...

Using environmental DNA to detect Microseira wollei (Oscillatoriales), a benthic harmful algal bloom, in Lake St. Clair (Michigan, USA)

Limnology and Oceanography: Methods, Volume 23, Issue 12, Page 949-959, December 2025.
Abstract Microseira wollei is a benthic cyanobacterium that can cause harmful algal blooms (HABs) and often requires management. However, a pervasive challenge for M. wollei management is characterizing the spatial and temporal extent of an impacted area, which can be time and resource intensive.

Comparative paralytic shellfish toxin accumulation in three important Aotearoa New Zealand marine invertebrate species: kina (Evechinus chloroticus), pāua (Haliotis iris) and hohehohe (Panopea zelandica)

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1252-1264, December 2025.
ABSTRACT This study investigated the potential for paralytic shellfish toxin (PST) accumulation in three of Aotearoa New Zealand's (NZ) taonga seafood species: kina (urchin; Evechinus chloroticus), pāua (abalone; Haliotis iris) and hohehohe (geoduck; Panopea zelandica) in laboratory exposures to the dinoflagellate Alexandrium pacificum.
