do all rivers have fish??
im curoious there's a stream at the bottom of my field that in some parts is about 2-3 meters wide and at the bottom of my field is about 1 meter or a weee bit bigger and i'd love to know if it has fish. my dad says is doesn't.
No, all rivers do not have fish. Like any animal, fish have certain requirements for their habitats. There are many different types of fish and each type has it's own needs. My guess would be that there aren't any large fish in your stream. I doubt a small stream could have enough space to meet the habitat requirements of most river fish. However, there could certainly be minnows. These fish are very tiny, but they make great bait for catching larger fish. There are certainly other types of animals in your stream as well. Depending on where you live, there might be small crayfish or sculpins. The mbgnet link below has lots of great information on animals found in rivers and streams.
It all depends if the water is highly polluted or not. If the fields near the stream uses insecticides or pesticides, then it would affect the organisms living inside it.
I hope my answer has helped you...
No, it depends if the water level is high enough and if it is highly polluted or not.
Not all rivers have fish
Yours might, though
