Description
Postlarval M. rosenbergii were grown for 28 days in freshwater aquaria
containing nine types of artificial solutions of calcium and magnesium.
Three calcium concentrations (0.05, 0.80, 1.55 mM) were varied against
identical concentrations of magnesium, producing water hardnesses
from 10-310 mg/1 as CaCO3. Shrimp were also grown in well water
whose calcium and magnesium levels matched those of one type of
artificial solution. Other major ions were added to artificial solutions
at concentrations similar to those in well water. Two replications
were run. There was no evidence that survival, final mean weights,
or food conversion ratios were influenced by calcium or magnesium concentrations.
Light intensities ranged from 20-55 ftc; there was a
suggestion that the higher illuminations were more favorable. Shrimp
grown in well water were significantly larger and had significantly
lower food conversion ratios than those grown in the matching artificial
solution. Well water may therefore contain growth-stimulating
substances.
