Question

A hurricane floods the mouth of a river that empties into the ocean. The inflow of salt water increases the salt content of the river water. Freshwater fish must stay in low salt environments. What will be the most likely response of the fish?

A.
swim downstream into the ocean
B.
stay where they are
C.
beach themselves on the shore
D.
swim farther up the river

Answer 1

swim farther up the river

Step-by-step explanation:
