A new study aims to collect information on sturgeon temporal and spatial distribution to inform offshore wind energy and sand leasing operations.

The Gulf sturgeon, Acipenser oxyrinchus desotoi, has been listed as Threatened since 1991. Beginning in 1986, USGS has been investigating sturgeon population abundance and ecology throughout its range, but mostly in the Suwannee River.

Connectivity among coral communities influences the probability of speciation and contributes to their ability to adapt to natural and anthropogenic stressors. Results from this study will enhance our understanding of Gulf ecosystems with regional conservation initiatives to inform the restoration of degraded deepwater coral communities and preserve long-term viability of coastal ecosystems.

WARC scientists work with local partners to verify and document sightings of non-native marine fishes.

WARC researchers evaluated whether outreach campaigns targeting pet owners are effectively reaching their desired audiences, namely pet owners who might unintentionally or purposefully release their pet into the wild.

WARC scientists will obtain live fish specimens from the field to conduct and enhance on-going laboratory research on harmful algal blooms and the use of piscicides to control invasive fish.

The USGS Joint Ecosystem Modeling team will use Bayesian networks to build a spatially explicit Everglades Vulnerability Analysis module based on current knowledge and existing data on fish density and biomass trends on the landscape.

USGS is collaborating with partners to develop a scientific vision for freshwater Mussel research.

Fish Slam events link research institutions such as museums and universities with federal, state, and local government agencies that possess expertise and field equipment to collect nonnative fishes, providing unique access to specimens for these institutions.

Fifty-seven fish biologists from 12 organizations participated in a three-day Fish Chat and Slam event in South Florida.

WARC researchers partnered with Gulf Sturgeon decision makers and biologists to develop a Bayesian network model that uses habitat characteristics to predict the quantity of juvenile winter foraging habitat under alternative river discharge and timing of juvenile arrival scenarios.

Fifty fish biologists from 15 organizations participated in a three-day Fish Chat and Slam event in South Florida on November 5-7, 2019.
