“…By sampling individually marked bass, an attempt has been made to describe their distribution along the shore- Shoop (1963) have all demonstrated the observance of a home range by the closely related smallmouth bass (M. dolomieui) as well as several other stream-dwelling centrarchids. Generally, their results show that the smaller species have a home range of 100-200 linear ft of stream whereas the larger species have a home range of 200-400 ft. Fajen (1962) in a study of home pools in streams found 15 of 187 smallmouth bass made voluntary trips of 100-2,350 ft to other pools.…”

By repeated sampling of a population of largemouth bass, including individually marked fish, and by use of reference markers along the shoreline, the observance of a home range by the bass was demonstrated. Of 96 recaptures considered, 59% were recaptured within 100 ft, 83% within 200 ft, and 96% within 300 ft of the original point of capture. The extent of movement away from the initial point of capture did not increase with time. After being offshore over winter the bass again demonstrated a marked tendency to resume the use of the same segment of shoreline they had frequented the previous summer. Straying from the home range followed by return to it was also observed. Observations on the dispersion of bass along the shoreline are given.

“…Fish and Savitz (1983) found bluegill home ranges of 0.15-0.75 ha lasting for 1-3 months and a negative relation between bluegill size and home range size for fish Ͻ190 mm total length (TL). In Tennessee streams, Gatz and Adams (1994) found linear home ranges of up to 17 km for bluegills, whereas linear home ranges for bluegills in Louisiana streams were typically less than 38 m (Gunning and Shoop 1963). To our knowledge, no one has investigated seasonal home ranges or home range size of bluegills in lentic habitats over a longer periods (e.g., 6 months).…”

“…However, bluegill movement, home range, and site fidelity are not well understood, particularly for lentic systems. Studies on bluegills in lotic systems have suggested that most fish are sedentary, few fish moving long distances (Gunning and Shoop 1963;Gatz and Adams 1994). Other species of Lepomis have also shown restricted movement in streams (e.g., Gerking 1953;Smithson and Johnston 1999).…”

Little is known about the distribution, movement, and home ranges of bluegills Lepomis macrochirus in lentic environments. Therefore, the objectives of this study were to evaluate the seasonal and diel differences in movement rates, site fidelity, and home range of bluegills in a shallow, natural Great Plains lake. A total of 78 bluegills (200-273 mm total length) were implanted with radio transmitters in March and May 2000. Of these fish, 10 males and 10 females were randomly selected and located every 2 h during one 24-h period each month from April to September 2000. Bluegill movement peaked during midsummer; however, there was little difference in diel movements, suggesting relatively consistent movement throughout the 24-h period. Home range estimates (which included the 24-h tracking plus an additional six locations from the same fish located once per day for six consecutive days each month) ranged up to 172 ha, probably because only about half of the bluegills exhibited site fidelity during any month sampled. Bluegill movement did not appear to be strongly linked with water temperature, barometric pressure, or wind speed. These results suggest that bluegills move considerable distances and that many roam throughout this 332-ha shallow lake. However, diel patterns were not evident. Sampling bluegills in Great Plains lakes using passive gears (e.g., trap nets) may be most effective during the summer months, when fish are most active. Active sampling (e.g., electrofishing) may be more effective than the use of passive gears in spring and fall, when bluegills are less active.

Reproductive Disruption in Wild Longear Sunfish ( Lepomis megalotis ) Exposed to Kraft Mill Effluent

Worldwide, wild fish living in rivers receiving municipal and industrial discharges may experience endocrine disruption as a result of exposure to anthropogenic pollutants. The purpose of this study was to evaluate the hormonal status of wild fish in a U.S. river receiving unbleached kraft and recycled pulp mill effluent (Pearl River at Bogalusa, LA). We evaluated two alternative hypotheses: the effluent contained constituents that suppressed male and female reproduction, or it contained an androgenic substance that masculinized females. To evaluate the likelihood of fish exposure to effluent, we marked 697 longear sunfish (Lepomis megalotis) over a 2-year period; 83% of recaptured fish were found at the site of initial capture, and only one fish migrated from an effluent-receiving site to a reference site. We can reasonably assume that fish captured from an effluent-receiving site are residents, not transitory migrants. To diagnose endocrine disruption, we measured sex steroid hormone [17β-estradiol (E2), testosterone (T), and 11-ketotestosterone (11KT)] and vitellogenin (VTG) concentrations in male and female longear sunfish captured at two sites upstream and two sites downstream of the effluent outfall. Kraft pulp mill effluent did not affect male reproductive physiology but did suppress female T and VTG levels when effluent constituted ≥ 1% of river flow. Masculinization was not observed. Longear sunfish in the Pearl River experience moderate reproductive suppression in response to unbleached kraft and recycled pulp mill effluent.
