Food selectivity of Bluegill and Green Sunfish Fry
… lagoon, were made available as food to green sunfish (Lepomis cyanellus) and bluegill (Lepomis macrochirus) fry, to examine their food selectivity. Green sunfish and bluegill fry ranged in size from 8.5-11.0 mm and 8.0-10.5 mm at stocking and were reared for 31 and 30 days, respectively. The …

Aspects of Bowfin and Northern Sunfish Biology and Ecology
… hormone injection. For many years, wild northern sunfish (Lepomis peltastes) in New York State have been restricted to a single 3.7 km section of lower Tonawanda Creek (LTWC), Erie County near Buffalo, NY, and the species is listed “threatened” in the state. A recovery program has been carried out …

Foraging ecology, sexual selection, and divergence in sunfish (Lepomis spp.)
… bluegill (Lepomis macrochirus) and pumpkinseed sunfish (Lepomis gibbosus), I examined three major questions: 1) how are diet and morphological variation related to alternative reproductive tactics in bluegill; 2) are sexual selection and disruptive selection driving divergence between foraging …

The effect of hybridization on metabolism and hypoxia tolerance in sunfish
Hybridization between species has the potential to exert pleiotropic effects on metabolism. Reduced fitness in hybrids may arise through incompatibilities between nuclear- and mitochondrial-encoded subunits of the enzyme complexes of oxidative phosphorylation. In my thesis, I examined metabolic …

Genetic Assessment of Rare Blackbanded Sunfish (Enneacanthus Chaetodon) Populations in Virginia
Enneacanthus chaetodon, the blackbanded sunfish, has become increasingly rare throughout its distribution in the Eastern United States. In Virginia, E. chaetodon maintains an endangered status and individuals persist in six populations. Mitochondrial DNA (mtDNA) and microsatellite data were …

Opercular Flaps as Sexual Ornaments For Male Longear Sunfish (Lepomis Megalotis)
… the exaggerated opercular flaps of male longear sunfish (Lepomis megalotis). The opercular flaps are soft scaleless extensions of the opercula which are conspicuously colored, associated with exaggerated gestures and sexually dimorphic for length. I investigated the effects of male opercular flap …

Characterization of Thermosensitive Preoptic Neurons in the Green Sunfish, Lepomis Cyanellus
… of 276 neurons in the preoptic region of green sunfish acclimated to 25(DEGREES)C were obtained using extracellular recording techniques and classified into 5 basic types. Type 1 neurons, which comprised 4% of the total, had low firing rates (approximately 5/second) at 25(DEGREES)C brain …

Spatiotemporal patterns in the distribution and abundance of the introduced Redbreast Sunfish (Lepomis auritus) and native Longear Sunfish (L. megalotis; Centrarchidae) in reservoirs of the Tennessee River drainage
The Redbreast Sunfish (Lepomis auritus) was introduced in the Tennessee River drainage (TRD) in the 1940s, and contemporary anecdotal evidence suggests that L. auritus is possibly displacing the native Longear Sunfish (Lepomis megalotis). This study aimed to characterize temporal patterns in …

The Food Habits of Redbreast Sunfish in the San Marcos River, Texas
Lepomis auritus, the redbreast sunfish, is a common sportfish in the San Marcos River, Texas. Since dietary analysis is an important step toward understanding the ecological role of a fish, data on the food habits of the redbreast sunfish in the San Marcos River were collected monthly from April, …

Movement and behavior of ocean sunfish, Mola mola, in the northwest Atlantic
<p>The ocean sunfish, Mola mola, has a worldwide distribution and is a common resident of the NW Atlantic Ocean. Notable for its unusual anatomy and large size, the biology of the species is largely unknown. I examined the movement and behavior of M. mola using pop-up satellite archival tags …

The toxicity of ozonated secondary-treated municipal waste effluent to blue-gill sunfish
… municipal waste effluent to bluegill sunfish was investigated in a continuous-flow bioassay system. Four bioassay experiments were conducted, one with untreated secondary effluent and three with ozonated, secondary effluent. Ozone was applied at dosages between 12.1 and 52.0 mg/l for …

Effects of exogenous androgens on parental care behaviour in male bluegill sunfish (Lepomis macrochirus)
… by manipulating androgen levels in bluegill sunfish (Lepomis macrochirus), a species where males provide sole parental care. I implanted males with testosterone, 11-ketotestosterone or flutamide, an androgen receptor blocker, and tested their nurturing behaviour and aggressiveness towards a …
