How does water flow affect fish?

Decreased stream flow can contribute to direct mortality if fish eggs are exposed, covered with silt, or left without sufficient, oxygenated water. Reduction in usable habitat can result in decreased abundance, size, and condition of fishes.

How do abiotic factors affect biotic factors in the ocean?

The abiotic factors will define which organisms are able or not to live in a specified place. The living organisms will constitute the biotic factors, which define if and how can an organism live in a specified environment. So, the abiotic factors are controling the biotic factors of an environment. Hope it helps you !
