Lecture Informs Public of Long Island’s Coastal Ills, Solutions

NCCOS-funded researcher Dr. Christopher Gobler and his students recently reported on the nearly complete collapse of hard clam fisheries in Great South Bay and bay scallop fisheries off the East End of Long Island due to annually occurring harmful algal blooms, hypoxia, and acidification. The team discovered excess nitrogen entering groundwater from septic tanks and […]

Traditional Palauan Practices Support Healthy Coral Reefs

A new study has demonstrated what Palauans have known for millennia—cultivated wetlands, in particular taro (Colocasia esculenta) fields, can control soil erosion and reduce the impact of watershed discharges on nearshore coral reefs. Taro fields in Palau are designed with embankments that allow a steady flow of water through the field, using the taro plants […]

NOAA Harmful Algae Research Featured at Interstate Seafood Seminar

NCCOS’s Dr. Quay Dortch was a featured speaker at the 66th Interstate Seafood Seminar conference during a session devoted to harmful algal blooms (HABs) and their impacts on shellfish safety and shellfish production. Dortch discussed NOAA’s HAB programs and how they enhance state rapid response and build a national capacity to minimize HAB impacts. She also […]

Sentinel Site Alerts California Public to Toxic Shellfish

Routine sampling of marine mussels from a University of California sentinel site at the Santa Cruz Wharf prompted the California Department of Public Health (CDPH) to issue a health advisory warning for domoic acid poisoning due to high levels of the toxin in shellfish samples. The April 4, 2014 advisory warned consumers not to eat recreationally […]

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 […]

New Pathogen and HAB Detection Device Designed with Volunteers in Mind

NCCOS-funded researchers at the University of Maine have developed a new, hand-held device for pathogen detection. The portable, easy-to-use, and inexpensive design of this sensor meets key use needs of volunteer and government public health, water, and shellfish monitoring personnel. Researchers plan to give these instruments to Maine Department of Marine Resources (DMR) harmful algal […]

Invasive Grass Carp and Impacts to Great Lakes

Non-native Grass Carp, introduced to U.S. ponds and lakes by federal and state agencies in the early 1960s, were considered a low cost, nonchemical alternative for aquatic weed control. Despite the common use of sterile Grass Carp as a biological control agent, scientists remain uncertain about the ecological risk the carp pose to North American freshwater […]

Guam Students Learn About Coastal Resilience and Conservation

Over a decade ago, fishermen in the village of Umatac (Humåtak) off the southwest coast of Guam found they were not catching the same size and quality of fish. Researchers identified one of the primary reasons to be an accelerated rate of erosion caused by the introduction of feral ungulates (pigs, goats, and deer) and […]
