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 […]

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 […]

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, […]

Can Asian Carp Barriers Protect the Great Lakes?

Invasive species such as zebra mussels have substantially changed the Great Lakes, with Asian carp poised to become the next and most serious invasive threat. Scientists leading a pioneering NCCOS-sponsored project to forecast the spread and bioeconomic impacts of aquatic invasive species have conducted an expert-based analysis of strategies to keep Asian carp out of Lake Michigan. The […]

New Lionfish Bioenergetics Model Predicts Impacts to Reef Biodiversity

NCCOS researchers have developed a new model to forecast the impacts of invasive lionfish consumption on Atlantic reefs. The model, published in Transactions of the American Fisheries Society, uses ambient water temperature and various physiological parameters to predict the energetic demands of lionfish populations. The model has been used to calculate the total number of […]

Addressing the Decline of Michigan’s Saginaw Bay

NCCOS-funded scientists participated in a recent forum held by the Michigan House Democrats’ Great Lakes and Conservation Task Force to address human-caused stresses to Lake Huron’s Saginaw Bay. The team presented findings and recommendations related to phosphorus inputs and eutrophication symptoms that are adversely affecting the bay’s fisheries and water quality. The NCCOS-funded team is […]

Restoring Saginaw Bay: NCCOS Provides Managers Science-based Recommendations

On May 22, NCCOS researchers delivered a set of recommendations to state and federal natural resource managers and policy makers focused on addressing multiple contaminant stressors impacting Saginaw Bay, one of several critical areas of concern identified by the EPA for restoration in Lake Huron. Findings from the  5-year project present state-of-the-science information on how stresses such as […]
