Surviving a Shrimp Cocktail: How to Spot Algae Shellfish Poisoning
Surviving a Shrimp Cocktail: Spotting Paralytic Shellfish Poisoning Anushka Rajagopalan 6/27/23 Whenever I’m in a coastal town, I make it a priority to try their seafood – it feels illegal to not get some fresh fish in for dinner! In locations such as Alaska, shellfish are harvested at numerous beaches and are a major staple.…
Read MoreNome Nugget article highlights 2022 research findings
An article in the 4/13/23 Nome Nugget summarized research findings on R/V Norseman II cruise in July-August 2022 when extremely high concentrations of Alexandrium were detected by the Imaging Flow Cytobot (IFCB). Health officials in six major communities across the Bering Strait and Seward Peninsula issued advisories about consuming shellfish. Here is the full article.

Significantly high concentrations of Alexandrium catenella were found in the Gulf of Alaska in July and August 2022 during the research cruise on the Norseman II. A health advisory was issued warning nearby communities that clabs, crabs, and tunicates in these waters could affect human and animal health. The full story in The Nome Nugget…
Read MoreResearchers raise concerns about Arctic food web
Hakai Magazine interviewed research biologists Evie Fachon at WHOI and Kathi Lefebvre at the NOAA Northwest Fisheries Science Center in Seattle, Washington for an article focusing on the potential for a significant increase in Alexandrium catenella harmful algal blooms due to warming Arctic waters. Alexandrium catenella blooms produce saxitoxin, a neurotoxin that paralyzes the nervous system…

Don Anderson gave a virtual presentation at the University of Alaska Fairbanks on 10/13/21 focusing on the potential for a significant increase in Alexandrium catenella harmful algal blooms due to warming Arctic waters. During annual blooms, the cells produce saxitoxins, potent neurotoxins, which accumulate in the food web and can lead to paralytic shellfish poisoning…

Evie Fachon was recently highlighted by PolarTREC, an educational research program for teachers. Evie and Victoria Uva are currently participating in a research cruise in the Arctic aboard the USCGC Healy. The objectives of this research are to investigate the distribution, prevalence, and geographic extent of HABs in Arctic waters, with an emphasis on the…
Read MoreUnderstanding HAB Dynamics in the Gulf of Maine
Harmful Algal Bloom Dynamics in the Gulf of Maine Coastal waters of New England are subject to annually recurring outbreaks of paralytic shellfish poisoning (PSP) caused by the dinoflagellate Alexandrium catenella. Another emerging threat in this region is amnesic shellfish poisoning (ASP) caused by toxic diatoms in the genus Pseudo-nitzschia. These blooms come with significant economic and social impacts,…
