These areas have anoxic condition means they have very little to zero dissolved oxygen hence cannot support marine/aquatic life. This is as a result of eutrophication caused by algae blooms. This phenomenon is brought about by pollution of these water reservoirs. These algae bloom take up all the oxygen in the water during their mass decomposgion hence leave no dissolved oxygen for the rest of the marine life.
I think it is because in the ocean the plankton produces most of the oxygen which is used by aquatic plants and plankton is a primary producer known as autotrops.
