Answer:
c. mouth of the river
Step-by-step explanation:
- As the stream and rivers all have one-directional flow o the fishes are generally found at the mouth of lakes and not at the river bottoms as these places are found to have cooler temperatures at the mouth of rivers.
- As the river is cleaner and clearer and has a good amount of oxygen the fish population will be found there. Other types of fish like catfish and carp can be found at the much shallower laces as these require less oxygen and have lower biodiversity.
- Hence, the freshwater fishes are found near the source of water it also depends on which location you want to catch the fish.
