Juvenile rockfish were the subjects of the experiment, a species that is popular in sport fishing and is also susceptible to overfishing due to its late reproductive age (twenty years) and its small amount of offspring. In the study, the fish were either placed in normal pH seawater, or in seawater with the acidity that is projected for the end of this century, then monitored with tracking software.
