Abstract
During 1993–1994, 78 adult striped bass Morone saxatilis captured in the Albemarle Sound–Roanoke River (AR) system were tagged with ultrasonic transmitters to examine summer patterns of distribution, migration, and habitat selection. Additionally, 626 striped bass were collected by electrofishing during 1993 to assess summer condition. Water temperatures within Albemarle Sound rose well above suitable levels for striped bass, but dissolved oxygen remained within tolerance limits. No stratification of temperature or dissolved oxygen occurred and no substantial thermal refuges were located. Telemetered striped bass were found throughout the Albemarle Sound system, selecting for deep water or structure. No evidence of migration to the Atlantic Ocean was found. During summer AR striped bass 325 mm total length or longer were in relatively poor condition, as evidenced by the extensive occurrence of red dermal lesions and ectoparasites. Relative weight (condition based on a standard weight at length) o...Keywords
