: Ecological implications.
The temporal dimension in fish recruitment: birth date, body size, and size-dependent survival in a sunfish (bluegill: Lepomis macrochirus
Helminths of bluegills, Lepomis macrochirus
, from a Northern Indiana Pond.
Here we surveyed the parasites of bluegill (Lepomis macrochirus
) and redbreast sunfish (Lepomis auritus) to: (1) inventory and provide a checklist of the parasites found in the Bull and Upatoi Creeks watershed, Muskogee County, Georgia, (2) compare seasonal variation in parasite richness and abundance, within a host species, (3) compare variation in parasite richness and abundance between host species, and (4) calculate indices of parasite biodiversity to potentially serve as an indicator (Marcogliese 2005) and ecological driver in future land-use models.
Optimal foraging and the selection of prey by the bluegill sunfish (Lepomis macrochirus
Boldness and behavioral syndromes in the bluegill sunfish, Lepomis macrochirus
The priority management species of largemouth bass (Micropterus salmoides), bluegill (Lepomis macrochirus
), and channel catfish (Ictalurus punctatus) comprised only 3% of the total biomass.
In a study conveyed by McComish (1968) in bluegills Lepomis macrochirus
, the criterion of presence (in females) or absence (in males) of a large, swollen, scaleless area surrounding the urogenital opening has been used in sexual determination.
Para Mann e Bidwell (2001), a diminuicao do oxigenio aumenta a toxicidade do nonilfenol (NP) e, para Hokanson e Smith (1971), do surfactante anionico alquilbenzeno linear para Lepomis macrochirus
Common species (5 to 10% of total catch) included blackside darter (Pereira maculata), largemouth bass (Micropterus salmoides), bluegill (Lepomis macrochirus
), pumpkinseed (Lepomis gibbosus), and round goby (Neogobius melanostomus).
In an experimental procedure, Vinyard (1979) showed that approximately 26% of the ostracods (Cypridopsis vidua) fed to bluegill sunfish (Lepomis macrochirus
) survived gut passage.
We analyzed VTG using a heterologous competitive ELISA developed for bluegill, Lepomis macrochirus
