<em>The number of fish would decrease.</em>
Explanation:
Ecological hypoxia can be described as a condition in which the oxygen level drops to such low levels in the aquatic ecosystem that it is no longer able to support aquatic life. In such a condition, the number of fishes declines at a rapid rate because fishes require oxygen as an essential element. Also, those fishes which do not have better adaptations to survive might get totally wiped out from the aquatic ecosystem.
