the river would have less water, so there would be less fish to catch
yes because black sea urchins are fished for their roe.
it would affect the fishing industry because all of the fishes would die from the oil spill.
As water moves downstream, it can transfer sediments, nutrients, pollutants, and organisms. This movement of materials and organisms can affect downstream ecosystems and water quality.
They reduce flow, and create a backpool which reduces flow downstream
It will kill the fishes
I need an answer!
Since we have no idea what "this" might be, we can't answer the question properly.
Downstream genetics refers to the genetic variations that directly affect an individual's traits, while upstream genetics refers to the genetic variations that influence the expression of downstream genes. Upstream genetics can have a broader impact on inherited traits by regulating the activity of downstream genes.
There is no commercial fishing -- thus no 'over-fishing' -- in Antarctica based on the the Antarctic Treaty.
Tides affect fishing because they can provide plenty of fish for fishermen. For example, when the tide is moving, it is more productive and doesn't have slack. When there is less of a slack, then there will be more fishes in the surf.
