Technology Transfer Between NOAA and France Improve Caribbean Ciguatoxin Detection

A PhD candidate from the French Research Institute for Exploitation of the Sea (IFREMER), Francesco Pisapia, is visiting the NCCOS Center for Coastal Fisheries and Habitat Research (CCFHR) for eleven weeks of intensive training on the method and technique of cytotoxicity assays to detect ciguatoxins (CTXs) and maitotoxins (MTXs) in fish tissue and cell cultures. […]

Toxic Pseudo-nitzschia Bloom Reported in Alaska’s Kachemak Bay

Volunteers with the NOAA’s Phytoplankton Monitoring Network reported a bloom of the diatom, Pseudo-nitzschia occurring within NOAA’s National Estuarine Research Reserve System at Kachemak Bay, AK.  NOAA’s Analytical Response Team identified the bloom as Pseudo-nitzchia australis using scanning electron microscopy and confirmed the bloom produced the neurotoxin domoic acid, after which, state managers of the […]

Association of Marine Lab Conference Features Caribbean Ciguatera Research

To raise awareness about a resurgence of Ciguatera Fish Poisoning (CFP) in the Caribbean and the current state of ciguatera research, NOAA’s National Centers for Coastal Ocean Science (NCCOS) led a special session on ciguatera at the Association of Marine Laboratories of the Caribbean 37th Scientific Conference in Willemstad, Curaçao, during the week of May […]

New Indicator for Gulf of Mexico Toxic Alga Shows Promise

NCCOS-sponsored scientists have discovered a simple indicator to predict one type of harmful algal species bloom or outbreak. The first potentially reliable biological indicator for forecasting a harmful algal bloom of the toxic dinoflagellate species Dinophysis ovum in the Gulf of Mexico is the presence of a primary food source, a small ciliate protozoan. The […]

Sensor Provides Early Warning of Toxic Algal Bloom in Offshore Waters of Monterey Bay

NCCOS-developed domoic acid sensors on board two Environmental Sample Processors (ESPs) deployed in Monterey Bay, California have provided early warning of a toxic Pseudo-nitzschia algal bloom. Only a week into the deployment that began in early May, particulate domoic acid levels exceeded 30 micrograms per liter of seawater, which was consistent with the ESPs also detecting very high concentrations […]

NCCOS Methods Transferred to Algal Toxin Testing Laboratory in Oman

NCCOS researcher Tod Leighfield trained three scientists with Oman’s Ministry of Agriculture and Fisheries in standard sample preparation and toxin detection methods as part of an International Atomic Energy Agency–funded project to establish a harmful algal bloom testing laboratory in the Arabian Gulf region. The training included assistance with set up of the laboratory and instruction on […]

NOAA, Partners Start Early Season Forecast Updates for Lake Erie Harmful Algal Blooms

This week, in response to increased demand for harmful algal bloom information, NOAA researchers and their partners at Heidelberg University began issuing new experimental, early season forecasts of the seasonal harmful algal bloom in western Lake Erie. The information will help resource and public health managers address the toxic blooms, which peak annually in late […]

Harmful Algal Cyst Mapping in Washington Shows 10-fold Increase since 2013

An unprecedented bloom of the harmful alga Alexandrium occurred during Fall 2014 in Quilcene Bay, Hood Canal, Puget Sound, WA; the outbreak contaminated shellfish with potent biotoxins that can cause paralytic shellfish poisoning. The area of the bloom was historically biotoxin free, but at the peak of the event, the Washington State Department of Health detected toxin […]
