Brine Shrimps tend to hatch in specific environmental conditions, such as high and low salt concentrations in water, weather and temperature. As one of the environmental conditions in which Brine Shrimp eggs hatch is water salinity and so, in this assignment, we were given 4 different salinity levels of water, which were 0%, 3%, 6% and 9%. As a result of the experiment, we noted that after 24 hours only one egg hatched at 3% salinity level and none at 0%, 6% and 9% levels. The second day, which was after 48 hours, there were 0 shrimps that hatched in 0% and 9% salinity levels, whereas at 3%, 7 out of 46(15.3%) eggs hatched and 6 out of 49(11%) at 6% levels. Based on this data our group concluded that the best level for hatching shrimps is 3%
