Answer:
Removing salt from ocean water and returning the removed salt to the bay. The resulting increase in salinity in the bay affect the fish populations because low levels of dissolved oxygen would increase.
Step-by-step explanation:
Desalination plants work by reverse osmosis, meaning energy is needed to push water past a membrane at high pressure in order to separate the salt (learn more how it works). A typical plant takes an average of 10 to 13 kilowatt hours of energy per every thousand gallons processed.
