Invasive Asian Carp Could Establish in Lake Erie with Little Effect to Native Fishery

A recent study found that if Asian carp establishes in Lake Erie, the native fisheries might not be significantly affected. Based on consultations with Great Lakes and fisheries specialists, the researchers estimated that Asian carp biomass could range from nearly zero to an even larger presence than the current walleye and yellow perch in Lake Erie. From […]

Spring Flood Outlook Has Implications for Gulf of Mexico and Chesapeake Bay Hypoxia

The NOAA 2014 U.S. Spring Flood Risk Assessment provides an important first look at some of the factors that influence summer hypoxia (low dissolved oxygen) in the Gulf of Mexico and the Chesapeake Bay. This year’s predicted elevated flood risk in the Upper Midwest and the Ohio River Valley may result in a larger hypoxic […]

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 […]

Managing America’s Corn Belt to Restore the Gulf of Mexico and Prairie Birdlife

NCCOS is participating in a public-private program to reduce nutrient inputs to the Gulf of Mexico hypoxic (“dead”) zone that managers expect to simultaneously benefit threatened native grassland bird species in steep decline The Eastern Tallgrass Prairie and Big Rivers Landscape Conservation Cooperative  (ETPBR LLC) is proposing a “Gulf Hypoxia Restoration Incentive Program” to reduce […]

New Tool to Assess Invasive Aquatic Plant Species Unveiled

Despite the long history of invasion by aquatic nuisance species to the Great Lakes, deciding which invasive species poses the biggest threat has proved to be a big challenge for natural resource managers and policy makers. Tools to assess the risks of invasion to the Great Lakes have either been inadequate or non-existent, even for […]

Invasive Asian Carp Movements Tracked Using ‘eDNA’

Asian carp are infiltrating major American waterways with the potential to greatly alter entire freshwater ecosystems.  Where are they going? A National Centers for Coastal Ocean Science-sponsored scientist–Dr. David Lodge of the University of Notre Dame– and his research team have developed genetic marker risk assessment tools for predicting where invaders such as Asian carp […]

NOAA Program Awards $2.5 Million for Research on Great Lakes Invasive Species

The National Centers for Coastal Ocean Science has awarded $2.5 million to the University of Notre Dame and partners to predict the next wave of invasive species likely to enter the Great Lakes and to identify cost-effective countermeasures. The project will be taking a strategic, big picture, look at Great Lakes invasive species. Although NCCOS […]
