Investigation Of Condition Effects On Batch Fecundity Of The Common Snook, Centropomus Undecimalis, In Tampa Bay, Florida, Catherine Michelle Bruger Hayslip
Investigation Of Condition Effects On Batch Fecundity Of The Common Snook, Centropomus Undecimalis, In Tampa Bay, Florida, Catherine Michelle Bruger Hayslip
USF Tampa Graduate Theses and Dissertations
Common snook, Centropomus undecimalis, is a popular game fish species that occurs throughout central and southern Florida, yet many questions remain unanswered regarding their reproductive strategies, including estimates of fecundity with relation to size, age, and condition of the female. These relationships are critical to improving stock assessments and fundamental to estimating spawning potential ratio, the measure by which snook are managed. Spawning snook were collected from a known spawning site, Rattlesnake Key, Tampa Bay, Florida, during three consecutive spawning seasons (2009-2011) and batch fecundity for snook was reported for the first time. Of the 43 females suitable for fecundity …
Molecular Technologies In The Science And Policy Of Florida Largemouth Bass Micropterus Floridanus Management In Florida, Josh Sakmar
USF Tampa Graduate Theses and Dissertations
Advances in molecular technologies have provided conservation biologist with the opportunity to quantify the genetic structure of a population and, in turn develop management guidelines and policies aimed at preserving the genetic diversity of fish stocks challenged by human activities. This thesis examines the status of genetics as applied to the management of freshwater fisheries by state natural resource agencies with a purpose of understanding the keys to a successful genetics program. An online survey was used to investigate the breadth of molecular marker application to freshwater fisheries management by state natural resource departments. Seven questions were posed to 50 …
Relative Survival Of Gags Mycteroperca Microlepis Released Within A Recreational Hook-And-Line Fishery: Application Of The Cox Regression Model To Control For Heterogeneity In A Large-Scale Mark-Recapture Study, Beverly J. Sauls
USF Tampa Graduate Theses and Dissertations
The objectives of this study were to measure injuries and impairments directly observed from gags Mycteroperca microlepis caught and released within a large-scale recreational fishery, develop methods that may be used to rapidly assess the condition of reef fish discards, and estimate the total portion of discards in the fishery that suffer latent mortality. Fishery observers were placed on for-hire charter and headboat vessels operating in the Gulf of Mexico from June 2009 through December 2012 to directly observe reef fishes as they were caught by recreational anglers fishing with hook-and-line gear. Fish that were not retained by anglers were …
Evaluation Of A Pilot Land-Based Marine Integrated Aquaculture System, Suzanne Boxman
Evaluation Of A Pilot Land-Based Marine Integrated Aquaculture System, Suzanne Boxman
USF Tampa Graduate Theses and Dissertations
Recirculating aquaculture systems (RAS) produce aquaculture products on land with minimal discharge of waste products and minimal water loss. High costs associated with waste treatment for RAS have triggered the growth of integrated aquaculture systems (IAS) which incorporate macrophytes (aquatic plants) into the treatment train. The objective of this research was to examine a pilot scale inland marine IAS with three different methods for solids treatment: a sand filter followed by a plant bed, only a plant bed, and geotextile bags. Florida Pompano (Trachinotus carolinus) were grown along with Smooth Cordgrass (Spartina alterniflora), Black Needle Rush …
