Hello, i have question why Bethesda no make a Water life (fish,shark...)? especially when have seen the size occupied by water on the map of fallout 4 ; while skyrim contained water life (carnivorous fish...)

No finished game ? and when the next update will take place?

Yeah there are the giant dolphin thing bodies you can find and you see lots of fish heads in the cannery and about, but nothing living in the water. I really liked how Skyrim added life to the water and was really disappointed in the lack of it in FO4. I've also watched some YouTube vids of people just exploring all the underwater areas and there's basically nothing down there. A real waste of space.

Wouldn't be surprised if we saw such in DLC.

They've clearly thought about it, with the corpses of several large marine animals to be found near the ocean. Also, there is in the game files a spear gun that has a bubble effect when shot. Modders have re-enabled it.

Whether this indicates that there was originally meant to be more underwater (which would have justified the aquaboy perk) that got scrapped due to time constraints or whether it forcasts plans for future DLC is up for grabs. I'd bet on the former, though.
