Eating USVI Invasive Lionfish Could Lead to Ciguatera Fish Poisoning

A new report by NCCOS-sponsored researchers shows that consumption of lionfish from the U.S. Virgin Islands (USVI) could lead to ciguatera fish poisoning. The research team analyzed ciguatera toxin levels in lionfish collected from waters surrounding USVI and found that about 40 percent of USVI lionfish have a measurable level of ciguatera toxin. The team […]

Texas Alerted to Toxic Pseudo-nitzschia Bloom in Galveston Bay

Volunteers with NOAA’s Phytoplankton Monitoring Network have reported a bloom of the diatom, Pseudo-nitzschia in Galveston Bay, Texas, and NOAA’s Analytical Response Team has confirmed that the bloom is producing domoic acid, a neurotoxin that can cause amnesiac shellfish poisoning. State managers of the Texas Parks and Wildlife Department and Texas Department of State Health […]

NCCOS-developed Method for Toxins Detection Approved for Regulatory Testing of Shellfish in the U.S

Earlier this year, the Interstate Shellfish Sanitation Conference (ISSC) approved a new assay developed by the National Centers for Coastal Ocean Science (NCCOS) as an official method for identifying toxicity that could result in paralytic shellfish poisoning. This approval is the culmination of more than a decade of effort to find an alternative to live animal […]

Common Brevetoxin Metabolite Found in Gulf of Mexico Oysters May Not be a Health Risk

Brevetoxin B2—an abundant shellfish metabolite of brevetoxin found in Gulf of Mexico oysters—does not readily pass through an intestinal barrier, rendering it unlikely to cause neurotoxic shellfish poisoning. The B2 metabolite is produced by oysters and many other animals by attaching the amino acid cysteine to the brevetoxin that is consumed by shellfish during blooms […]

NCCOS Identifies Cause of Large Fish Kills in North Carolina Estuaries

In recent years, North Carolina estuaries have experienced large fish kills often associated with rains and moderate temperatures. Most of the dead fish have exhibited large, open skin ulcers. Scientists at NCCOS analyzed the ulcerated fish collected by the North Carolina Department of Environment and Natural Resources (NCDENR) and the Neuse Riverkeeper Foundation using molecular assays […]

NCCOS Coordinates Development of New Korean Project on Harmful Algae

NCCOS staff chaired a two-day meeting in Busan, Republic of Korea (August 29–30, 2013) convened to finalize a new collaborative project on harmful algae. The project, one component of the larger Joint Project Agreement (JPA) between NOAA and the newly formed Korean Ministry of Oceans & Fisheries, will focus on issues related to the monitoring […]

NCCOS Aids Pennsylvania Response to First CyanoHAB in Presque Isle Bay, Lake Erie

The NCCOS Harmful Algal Bloom Event Response Program is assisting the Pennsylvania Department of Environmental Protection (PA DEP) respond to and document the first cyanobacteria harmful algal bloom (cyanoHAB) in Presque Isle Bay, along the south shore of Lake Erie. Researchers sampled the small scale bloom near Presque Isle State Park in late July, and […]

July Field Mission in St. Thomas USVI Marine Reserve

On July 20-25, scientists from the National Centers for Coastal Ocean Science (NCCOS) will conduct a follow-up field mission to the St. Thomas East End Reserves (STEER). The work is part of a project requested by local resource managers to develop an integrated ecosystem assessment for the STEER.  Results from contaminants assessment to be published […]
