Assessing Invasive Asian Carp’s Potential to Spread to Great Lakes

Invasive Asian carp have established themselves in many lakes and river systems in the upper mid-West. Once established, they have wreaked havoc on existing food chains. Some of these invasive carp have been caught in Lake Erie. In anticipation of a possible invasion of the Great Lakes system, researchers from the National Centers for Coastal […]

First Estimates of Trap Debris in Florida Keys National Marine Sanctuary Now Available

Over 85,000 spiny lobster ghost traps and over 1 million non-fishing traps or remnants of traps are estimated to be present on the seafloor of the Florida Keys National Marine Sanctuary. Researchers from the National Centers for Coastal Ocean Science and the Florida Fish and Wildlife Conservation Commission calculated these estimates following completion of 151 […]

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 […]

Marine Shellfish Get a ‘One-Two Punch’ from Acidification and Low Oxygen

Recent research has shown that ocean acidification and low oxygen interact to harm early life stages of bay scallops (Argopecten irradians) and hard clams (Mercenaria mercenaria). The study, conducted by Stony Brook University and sponsored by NCCOS and NOAA’s Ocean Acidification Program, found that the combined effects of low pH (high acidity) and low oxygen […]

Environmental Conditions Can Influence Development of Dermo Disease in Oysters

A recent NCCOS-sponsored study by the Smithsonian Institution showed that long-term exposure to daily fluctuations of hypoxia (low dissolved oxygen) increased Dermo disease (Perkinsus marinus) infection in previously uninfected eastern oysters. Surprisingly, daily-cycling pH (a measure of acidity) did not affect Dermo disease infection levels in conjunction with daily-cycling hypoxia or with continuous normal oxygen […]

Ocean Sciences Meeting Highlights Results of Sponsored Research

The 2014 Ocean Sciences Meeting showcased the reach and extent of research sponsored by NCCOS, including coral reefs, harmful algal blooms, hypoxia, applying research to management solutions, and integrated ecosystem assessments. NCCOS staff and sponsored research scientists gave over 25 oral and poster presentations and co-chaired a special session on mapping, monitoring, and managing mesophotic […]

Aqua Kids Features NCCOS Science on Marine Invasive Species and Aquaculture

A recent episode of Aqua Kids, a children’s television show that reaches over 90 million households, visited NCCOS’s Center for Coastal Fisheries and Habitat Research in Beaufort, N.C., to learn more about the center’s research. During the episode, the Aqua Kids explored NCCOS research on sustainable marine aquaculture and how invasive species, such as lionfish, […]
