NCCOS Science Supports Designation of New Marine S...

Originally built as the Nancy Dousman in 1832, the schooner Gallinipper is Wisconsin's oldest shipwreck discovered to date. The 95-foot long schooner linked Wisconsin coastal cities with distant markets in ...

Potential Effects of Bigheaded Carps on Four Great...

A NCCOS study, co-sponsored with the Great Lakes Restoration Initiative, used an ecosystem model to evaluate the potential risk of two species of highly invasive bigheaded carp fish (a type ...

Shoreline Armoring Promotes Spread of Invasive Ree...

A stand of Phragmites australis. Credit USDA. An NCCOS-funded study found that shoreline armoring in Chesapeake Bay promotes the spread of the invasive common reed (Phragmites australis) by stimulating greater ...

Nanobubble Ozone Technology Shown to Eliminate Inv...

An independent quality control testing laboratory has validated NCCOS research findings on nanobubble ozone technology (NBOT), confirming it is highly effective in controlling algae, bacteria, and motile zooplankton in ship ...

Mussel Watch Detects New Contaminants in Great Lak...

Scientists from NOAA's National Centers for Coastal Ocean Science (NCCOS) have published an assessment of contaminants of emerging concern in the Great Lakes. Of the 237 chemicals the team analyzed, ...

Science and Stewardship: Keys to Restoring Kachema...

Kachemak Bay, Alaska, has experienced significant declines in shrimp and crab that have not recovered despite fishery closures. NOAA has designated the bay a Habitat Focus Area, bringing together science, ...

Determining Ciguatera Risk in Invasive Lionfish

The lionfish is invasive to the Atlantic, Gulf of Mexico, and Caribbean. Credit: NOAA Scientists are investigating the prevalence of ciguatera toxins in invasive lionfish in response to interest in ...

Lionfish Prefer to Eat Local

In recent years, Indo-Pacific lionfish have been found in coral reefs throughout the southeast Atlantic, Gulf of Mexico, and Caribbean. Credit: NOAA Invasive lionfish are generalist, opportunistic predators, meaning they ...

A Manual of Previously Recorded Non-indigenous Invasive and Native Transplanted Animal Species of the Laurentian Great Lakes and Coastal United States

This manual presents geographic information by state of occurrence, and descriptions of the socio-economic impact created by the invasion of nonindigenous and native transplanted animal species in the Laurentian Great Lakes and the coastal waters of the United States. It ...

A surveillance strategy for invasive species of concern in deepwater habitats of the Northwestern Hawaiian Islands

This document provides strategies to detect deepwater invasive species in the Northwestern Hawaiian Islands (NWHI) in support of the Papahanaumokuakea Marine National Monument (PMNM). The strategies use technical diving to conduct visual surveys and focus on two invasive species of ...

An integrated assessment of the introduction of lionfish (Pterois volitans/miles complex) to the western Atlantic Ocean

Lionfish (Pterois volitans/miles complex) are venomous coral reef fishes from the Indian and western Pacific oceans that are now found in the western Atlantic Ocean. Adult lionfish have been observed from Miami, Florida to Cape Hatteras, North Carolina, and juvenile ...

An Investigation of Survey Technologies and Modeling Techniques for Improving Deepwater Surveys of Nonindigenous Species in the Northwestern Hawaiian Islands

This report examines survey technologies, with a focus on towed camera systems (TCSs), and modeling techniques which can increase nonindigenous species (NIS) detection and sampling efficiency in deepwater habitats of Northwestern Hawaiian Islands (NWHI); thus filling a critical data gap ...

Aquatic invasive species transport via trailered boats: what is being moved, who is moving it, and what can be done?

Trailered boats have been implicated in the spread of aquatic invasive species. There has been, however, little empirical research on the type and quantity of aquatic invasive species being transported, nor on the efficacy of management interventions (e.g., inspection crews, ...

Biology, Ecology, Control and Management of the Invasive Indo-Pacific Lionfish: An Updated Integrated Assessment

Venomous Indo-Pacific lionfish (Pterois miles and P. volitans) are now established along the Southeast U.S.A. and parts of the Caribbean and pose a serious threat to reef fish communities of these regions. Lionfish are likely to invade the Gulf of ...

Ecological Assessment of Wisconsin - Lake Michigan

This report is an assessment of key physical, chemical, and biological attributes that influence the natural and cultural resources of western mid-lake Lake Michigan. It is a synthesis of existing scientific literature and a collection of new ecological data that ...

Eurasian watermilfoil fitness loss and invasion potential following desiccation during simulated overland transport

Vegetative reproduction promotes human-mediated dispersal of aquatic invasive plants as fragments “hitchhike” between water bodies on boats and trailers. However, desiccation of plant fragments may also reduce fitness, decreasing the likelihood of fragment survival as transport distances increase. Current inter-lake ...

Intersex in male invasive Atlantic lionfish, Pterois spp

Intersex in gonochoristic species is a reproductive abnormality in which an individual produces gametes of the type normally associated with the opposite sex. To investigate the prevalence of intersex in male lionfish Pterois spp., 884 individuals were collected from the ...

Limitations of gravity models in predicting the spread of Eurasian watermilfoil

The effects of non-native invasive species are costly and environmentally damaging, and resources to slow their spread and reduce their effects are scarce. Models that accurately predict where new invasions will occur could guide the efficient allocation of resources to ...
