C. Seals et al., ENVIRONMENTAL CALCIUM DOES NOT AFFECT PRODUCTION OR SELECTED BLOOD CHARACTERISTICS OF SUNSHINE BASS REARED UNDER NORMAL CULTURE CONDITIONS, The Progressive fish-culturist, 56(4), 1994, pp. 269-272
The effects of environmental calcium (5, 10, 20, 40, and 80 mg/L) on p
roduction and selected blood characteristics of sunshine bass (female
white bass Morone chrysops x male striped bass M. saxatilis) under nor
mal culture conditions were investigated in two 6-week trials. Environ
mental calcium had no significant effects on growth, food conversion,
condition factor, hematocrit, plasma osmolality, or plasma calcium con
centrations. Previous studies have indicated that environmental calciu
m is advantageous under stressful conditions; however, this study indi
cated that elevated calcium levels offer no advantages during apparent
ly nonstressful periods.
