The goal of this study was to develop an ionic environment containing 1 g/L total dissolved solids (TDS) that would support the survival and growth of juvenile blue crabs (designated a “mixed-ion solution”). The 1 g/L TDS level was selected in order to minimize the cost of preparing ponds and to potentially reduce the need for effluent permitting in inland areas. The general approach was to provide selected ions in approximate concentrations found in 1 g/L dilute seawater.
In a series of three-week exposures beginning with ~20 mm carapace-width crabs, we found:
These results indicate that blue crabs can survive and grow in 1 g/L mixed-ion solution. This work was supported with funding by the Mississippi Department of Marine Resources.
