Use of Additional Calcium in Soft-water Ponds for Improved Striped Bass Survival

Fingerling production and post-harvest survival were compared for striped bass (Marone saxatilis) produced in ponds with low «2 mg/liter) levels of calcium and in ponds where calcium was increased (14-40 mg/liter) by the addition of calcium chloride. Production pond calcium levels were not correlated with fry survival, or biomass production in ponds. Post-harvest survival of fingerlings from treated ponds was significantly better than post-harvest survival of fish from control ponds.
