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 ...

Saxitoxin Linked to Deaths of Northern Fur Seals in the Southeast Bering Sea

Marine Mammal Science, Volume 41, Issue 4, October 2025.
ABSTRACT In August 2024, a northern fur seal mortality event was observed on St. Paul Island, AK in the southeast (SE) Bering Sea. Ten seals in good body condition were found dead along with large accumulations of dead fish on Benson Beach located on St. Paul Island.

Influence of a Tribally Led Children's Environmental Education Program on Shellfish Harvesting Beliefs and Behavioral Intentions

Community Science, Volume 4, Issue 3, September 2025.
Abstract To increase the understanding of shellfish toxin risks and support safe harvesting practices, the Sitka Tribe of Alaska develops and organizes environmental education programs. This study (ClinicalTrials.gov ID: NCT05247229) evaluates the Tribe's new middle school program, drawing on the theory of planned behavior to investigate pre‐post ...

Route of metabolization and detoxication of paralytic shellfish toxins in humans

Toxicon, 2010
Paralytic shellfish toxins (PST) are a collection of over 26 structurally related imidazoline guanidinium derivatives produced by marine dinoflagellates and freshwater cyanobacteria. Glucuronidation of drugs by UDP-glucuronosyltransferase (UGT) is the major phase II conjugation reaction in mammalian liver.

Liquid Chromatographic-Fluorometric Analysis of Paralytic Shellfish Toxins

Agricultural and Biological Chemistry, 1984
Alkaline oxidation of paralytic shellfish toxins with ten-butyl hydroperoxide yielded highly fluorescent derivatives. Even gonyautoxins I and IV and neosaxitoxin, which were nonfluorescing by previously proposed hydrogen peroxide oxidations, were successfully converted to fluorescent compounds.

Neurotoxins from Marine Dinoflagellates: A Brief Review

Marine Drugs, 2008
Dinoflagellates are not only important marine primary producers and grazers, but also the major causative agents of harmful algal blooms. It has been reported that many dinoflagellate species can produce various natural toxins.
