Title	Prey Selection by Young Lemon Sharks (Negaprion brevirostris) at Chandeleur Island Nursery Habitats with a Comparison to Three Other Co-Occurring Shark Species
Author	Davis, Christopher
Document Type	Master's Thesis
Keywords	lemon shark, Chandeleur Islands, nursery habitat, Biloxi Marshes, sharks
Abstract	The Chandeleur Islands (Louisiana) contain nursery habitats for lemon sharks that provide abundant prey and protection from predation. Other local shark species (Atlantic sharpnose, bull, and blacktip sharks) co-occur with lemon sharks in the same region, including the nearby Biloxi Marshes. To better assess how lemon sharks use these nursery habitats, I measured diet and prey availability of young of the year and juvenile lemon sharks from 2009 to 2010. Young lemon sharks at the Chandeleur Islands have a relatively reduced diet breadth in comparison to those from nurseries in Bimini (Bahamas) and the Florida Keys. At the Chandeleur Islands, young lemon sharks appear to be opportunistically feeding on the most abundant prey items, resulting in high prey abundance and low diversity in their diet. Opportunistic feeding by young lemon sharks suggests minimal dietary overlap with other local shark species, resulting in minimal competition for resources.
