Acoustic telemetry of shark movements and residency near artificial habitats in the northern Gulf of Mexico

Altobelli, Ashley (2019-04-24)

In the present study, acoustic telemetry was used to monitor the movements and residency of seven Sandbar Sharks Carcharhinus plumbeus, five Atlantic Sharpnose Sharks Rhizoprionodon terraenovae, four Bull Sharks Carcharhinus ...

Age determination through shape analysis and validation of otolith annular increments in red snapper, Lutjanus campechanus

Beyer, Sabrina (2008-05-15)

The periodicity and timing of otolith growth rings in red snapper was examined through a mark-and-recapture study and with known-age, hatchery-reared fish. In 2005 through 2008, red snapper (n = 265) were caught hook-and-line, ...

Age frequency, growth, mortality and PAH levels of roughtongue bass, Pronotogrammus martinicensis, following the Deepwater Horizon oil spill

Biermann, Lindsay (2016-12-06)

The 2010 Deepwater Horizon (DWH) oil spill and its immediate effects on the surrounding ecosystems have been extensively examined, but longer term effects are still widely unknown. Among the regions potentially affected ...

A Comparison of Fish and Epibenthic Assemblages on Artificial Reefs With and Without Copper-Based Anti-Fouling Paint

Miller, Dianna (2008-05-15)

Artificial reefs attract fish, but whether or not actual production occurs remains unclear. To examine this question, fish and epibenthic assemblages were compared between reefs with and without copper-based anti-fouling ...

A comparison of the size and age distribution of red snapper Lutjanus campechanus to the age of artificial reefs in the northern Gulf of Mexico

Syc, Tara (2011-04-12)

Size and age of red snapper, Lutjanus campechanus, were sampled from April through November 2010 and compared with the age of the artificial reef at the site of capture. Artificial reefs were deployed in 2006 (n=20, 4 ...

The effects of tournament fishing on dispersal, population characteristics, and mortaltiy of black bass in Lake Martin, Alabama

Ricks, Benjamin (2006-05-15)

A great deal of black bass Micropterus spp. tournament activity occurs at Wind Creek State Park (WCSP), located at the north end of Lake Martin, Alabama. Because of the popularity of this location as a tournament processing ...

Estimation of Red Snapper Abundance on Oil and Gas Platforms in the northern Gulf of Mexico based on Mark Recapture Methods

Osowski, Ana (2019-11-19)

Estimating abundance of sport and commercial reef fish species remains difficult due to cryptic habitat use patterns. One such species is Red Snapper, Lutjanus campechanus, which is perhaps the most important fish species ...

Fine-scale movements and home ranges of red snapper Lutjanus campechanus around artificial reefs in the northern Gulf of Mexico

Piraino, Maria (2011-11-14)

Few studies have examined fine-scale movement patterns of continental shelf marine fishes. For example, little is known about an important marine species, red snapper Lutjanus campechanus, and its fine-scale movement ...

Gray Triggerfish, Balistes Capriscus, Reproductive Behavior, Early Life History, and Competitive Interactions Between Red Snapper, Lutjanus campechanus, in the Northern Gulf of Mexico

Simmons, Carrie (2008-08-15)

Gray triggerfish, Balistes capriscus, is a widely distributed species, important to both commercial and recreational fisheries. Other species of Balistidae display atypical behaviors compared to most other marine fishes ...

Horizontal and Vertical Movement, Residency and Mortality of Gray Triggerfish (Balistes capriscus) on Artifical Reefs in the Northern Gulf of Mexico

McKinzie, Megan (2018-12-03)

The present telemetry study evaluated movements of gray triggerfish (Balistes capriscus) on artificial reefs in the northern Gulf of Mexico from 23 January 2013 through 5 September 2017. Five Vemco Positioning System (VPS) ...

Juvenile Density, Fishing Mortality, and Habitat use of Red Snapper, Lutjanus campechanus, on Artificial and Natural Reefs in the Northern Gulf of Mexico.

Mudrak, Peter (2020-11-18)

The Red Snapper, Lutjanus campechanus, fishery in the Gulf of Mexico has been intensively regulated as managers attempt to rebuild the fishery. This has led to a need for improved data collection, and a better understanding ...

Movement, dispersal, and home ranges of tournament displaced largemouth and spotted bass in Lake Martin, Alabama

Hunter, Ryan (2006-12-15)

Anglers fishing in black bass tournaments often displace fish great distances from their site of capture and the effects of tournament displacement on movement and behavior of fish after release have been variable. ...
