Five 400 mL beakers each filled with 200 mL of deionized water and different percentages of salt had 11 brine shrimp in each of them. The best salt condition in this lab closely parallels the conditions set in real life for the brine shrimp.
Salt is necessary for the biological processes of many aquatic organisms.
However, too high an amount of salinity can be harmful to them. Brine shrimp though have evolved to survive in environments with relatively high salinity. This experiment was conducted to test the range of tolerance that the shrimp have developed through evolution. The brine shrimp were observed in varying conditions of salt water to figure out the critical points at which they can no longer survive. The general approach to this experiment was to set up five individual 400 mL beakers with 200 mL of deionized water in them with different percentages of salt in relation to the volume and weight ratio.
