Evaluating Lethal And Sub-Lethal Effects Of Catch-And-Release Angling In Florida's Central Gulf Coast Recreational Atlantic Tarpon (Megalops Atlanticus) Fishery, Kathryn Yvonne Guindon Jan 2011

Evaluating Lethal And Sub-Lethal Effects Of Catch-And-Release Angling In Florida's Central Gulf Coast Recreational Atlantic Tarpon (Megalops Atlanticus) Fishery, Kathryn Yvonne Guindon

Graduate Theses and Dissertations

Atlantic tarpon are sought after because of their fighting ability on various tackle and support a popular, lucrative and predominantly catch-and-release recreational fishery in Florida. They are not commercially harvested or consumed by the general public, therefore assessing effects of catch-and-release angling on tarpon survival is critical to a sustainable fishery. Tarpon caught on artificial breakaway jig and traditional live bait fishing charters in Boca Grande Pass (n=42) and trips from the recreational fishery of Tampa Bay (n=40) were tagged with ultrasonic transmitters and tracked up to 6 hours immediately following release to estimate post-release mortality. Of the ...


Influence Of Temperature On Yolk Resorption By Centropomus Undecimalis Larvae, Claudia Catalina Baron-Aguilar Jan 2011

Influence Of Temperature On Yolk Resorption By Centropomus Undecimalis Larvae, Claudia Catalina Baron-Aguilar

Graduate Theses and Dissertations

In an effort to determine the optimal temperature for rearing Centropomus undecimalis larvae during the yolk resorption period, larval development was measured under four different temperature regimes (23, 25, 28 and 31 °C). The eggs were incubated at 28 °C until hatching, which occurred at about 17 hours post-fertilization. After hatching, temperatures were adjusted to the respective treatment levels. Measurements were collected from 25 individual larvae across rearing temperatures at the following pre-determined time intervals: at hatching, 24 hours post hatch (hph), 48 hph, and 72 hph. Morphometric measurements were obtained from photomicrographs, including yolk sac length and height, oil ...


Relative Abundance And Spatial Distribution Of Lepomid Sunfishes In The Peace River, Justin Henry Heller Jan 2011

Relative Abundance And Spatial Distribution Of Lepomid Sunfishes In The Peace River, Justin Henry Heller

Graduate Theses and Dissertations

This study examines spatially continuous sampling data in order to investigate patterns of abundance and distribution of three recreationally important sunfish species (bluegill, redear, and spotted sunfish) along the main-stem of the Peace River, a large softwater river located in southwest Florida. A total of 467 electrofishing transects were sampled biannually from spring 2008 to spring 2010. Sampling sites ranged from the headwaters of the Peace River in Polk County, FL to the oligohaline waters located in Charlotte County, FL. All fish were collected with boat mounted electrofishing gear, and aquatic habitat and physiochemical water quality measurements were recorded at ...
