Water reflects and scatters the light that strikes it; this is shown by the fact that you can see your reflection in puddles. When the sky is brilliant blue, the sea is also, because it reflects the blue of the sky.
The sea refracts light just as the sky does.
Blue light is more easily bent, or refracted, than red light; thus, light refracted back from the surface of the sea appears blue. Furthermore, when you are underwater the water around you appears blue because more blue light is scattered back to your eye than red light.
Or maybe, like you suggested, fish have blue piss!

I was on a ferry once in Toronto on the way over to Centre Island, and a wee boy asked why the lake was green, and why the ocean was blue. She told him she didn't know why the ocean was blue, but the lake water was green because that was the colour of their dishwater detergent.........

So many serious answers. I thought that it was from the whales. The are blue aren't they? I just thought they were fading from being in the water.

It is a reflection of the sky.
The deeper you get the darker it gets.
Nothing to do with fish piss - that is orange.
