Aging Of Florida Blue Crabs, Callinectes Sapidus, Through The Biochemical Extraction Of Lipofuscin, Claire Elizabeth Crowley

Graduate Theses and Dissertations

The blue crab, Callinectes sapidus, represents an ecologically and economically important component of marine and estuarine ecosystems. In Florida, blue crab landings accounted for $9.6 million dollars during the 2010 fishing season. Accurate stock assessments for this valuable fishery are essential. Age is a critical biological component of accurate stock assessments; however, blue crabs and other crustaceans are especially difficult to age because of the complex nature of discrete growth. Biochemical extraction of an aging pigment, lipofuscin, was developed using blue crab eyestalks. The current study investigated the effects of freezing preservation on lipofuscin extracts and examined whether the ...

Fishermen, Politics, And Participation: An Ethnographic Examination Of Commercial Fisheries Management In St. Croix, U.S. Virgin Islands, Cynthia Grace-Mccaskey

Graduate Theses and Dissertations

Currently, there is widespread debate regarding the overall status of the world's fisheries, with some researchers projecting their total collapse in only a few decades, and others concluding the situation is not quite as bleak. Additional debates include what strategies should be used to manage fisheries at various scales, and further research is needed to determine which strategies are most appropriate for use in particular situations and locales, as context is critical.

Recently, prominent common pool resources scholars have expressed the need for ethnographic approaches to studying resource management institutions in order to move beyond the current focus of ...
