Gulf Sturgeon Ecological Investigations
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.
Sturgeon Occurrence and Behavior in the Outer Continental Shelf
A new study aims to collect information on sturgeon temporal and spatial distribution to inform offshore wind energy and sand leasing operations.
Preserving Gulf Sturgeon—A Fish Tale of Gargantuan Proportions
It's hard to imagine a better job than doing fieldwork with the USGS Coastal Ecology crew as they work to keep tabs on the Gulf sturgeon population.
The Oysters of Chicopit: Status of the Oyster Population in Chicopit Bay before, during, and after the Construction of the Mile Point Project
Chicopit Bay, part of the Timucuan Ecological and Historic Preserve in Florida, is a small embayment at the intersection of San Pablo Creek (part of the Intercoastal Waterway) and the St. Johns River. Home to a number of small oyster beds, this area is now being dredged to help eliminate cross currents from the main shipping channel of the St. Johns. WARC researchers collect baseline environmental...
A Bibliography of All Known Publications & Reports on the Gulf Sturgeon Acipenser oxyrinchus desotoi (through 31 December 2013)
This functional bibliography is meant to be a complete and comprehensive bibliography of all discoverable reports containing information on the Gulf Sturgeon (GS). This bibliography contains all known reports presenting, documenting, summarizing, listing, or interpreting information on the GS through 31 December 2013.
The Oysters of Chicopit Bay, Florida, 2016-2018 The Oysters of Chicopit Bay, Florida, 2016-2018
This data set was generated to evaluate the status and response of oysters within Chicopit Bay, FL, in the Timucuan Ecological and Historic Preserve during and following dredging completed by the Army Corps of Engineers for the Mile Point Project. It includes live oyster area estimates from aerial images collected in 2016-2018.
Data release to Suwannee River Water Management District: Gulf Sturgeon Upper Suwannee River movements (2011-2019) Data release to Suwannee River Water Management District: Gulf Sturgeon Upper Suwannee River movements (2011-2019)
This data set was compiled for the Suwannee River Water Management District for use in determining Minimum Flows and Levels. The data set contains detection summaries of acoustically tagged adult Gulf sturgeon using the Upper Suwannee River areas equipped with Innovasea Vemco acoustic receivers (2011-2019).

New insights reveal a temporally distinct two-stock genetic structure for Suwannee River Gulf sturgeon New insights reveal a temporally distinct two-stock genetic structure for Suwannee River Gulf sturgeon
Understanding population genetic structure and patterns of gene flow is important for effective decision making and the preservation of genetic diversity, especially when managing protected species. Historically, Gulf sturgeon have been managed by river system, with early evidence supporting spatially distinct genetic structure across 7 natal populations. However, an increasing number of...

From field station to forecast: Managing data at the Alaska Volcano Observatory From field station to forecast: Managing data at the Alaska Volcano Observatory
The Alaska Volcano Observatory (AVO) uses multidisciplinary data to monitor and study dozens of active and potentially active volcanoes. Here, we provide an overview of internally and externally generated data types, tools and resources used in their management, and challenges faced. Data sources include the following: (1) a multiparameter (seismic, infrasound, GNSS, web cameras) ground...

Temporal and spatial relationships of Yellowfin Tuna to deepwater petroleum platforms in the northern Gulf of Mexico Temporal and spatial relationships of Yellowfin Tuna to deepwater petroleum platforms in the northern Gulf of Mexico
In 2006–2007, 110 Yellowfin Tuna Thunnus albacares were tagged with acoustic transmitters near deepwater oil platforms and one drillship in the northern Gulf of Mexico off the Mississippi River delta to determine the extent to which platforms act as fish aggregating devices (FADs). Vemco acoustic receivers were installed on six deepwater platforms to detect the presence of tagged...

Regional-scale variability in the movement ecology of marine fishes revealed by an integrative acoustic tracking network Regional-scale variability in the movement ecology of marine fishes revealed by an integrative acoustic tracking network
Marine fish movement plays a critical role in ecosystem functioning and is increasingly studied with acoustic telemetry. Traditionally, this research has focused on single species and small spatial scales. However, integrated tracking networks, such as the Integrated Tracking of Aquatic Animals in the Gulf of Mexico (iTAG) network, are building the capacity to monitor multiple species...

Assessment of adult pallid sturgeon fish condition, Lower Missouri River—Application of new information to the Missouri River Recovery Program Assessment of adult pallid sturgeon fish condition, Lower Missouri River—Application of new information to the Missouri River Recovery Program
During spring 2015, Nebraska Game and Parks Commission (NGPC) biologists noted that pallid sturgeon (Scaphirhynchus albus) were in poor condition during sampling associated with the Pallid Sturgeon Population Assessment Project and NGPC’s annual pallid sturgeon broodstock collection effort. These observations prompted concerns that reduced fish condition could compromise reproductive...

Status of scientific knowledge, recovery progress, and future research directions for the Gulf Sturgeon, Acipenser oxyrinchus desotoi Vladykov, 1955 Status of scientific knowledge, recovery progress, and future research directions for the Gulf Sturgeon, Acipenser oxyrinchus desotoi Vladykov, 1955
The Gulf Sturgeon, Acipenser oxyrinchus desotoi, is an anadromous species of Acipenseridae and native to North America. It currently inhabits and spawns in the upper reaches of seven natal rivers along the northern coast of the Gulf of Mexico from the Suwannee River, Florida, to the Pearl River, Louisiana, during spring to autumn. Next to the Alligator Gar (Atractosteus spatula), the...
