We have a question about desalinating water while stranded at sea, and another that asks if you can get desalinated water from eating fish.

However, even if you could get desalinated water from fish which, how likely is it that one would be able to catch enough fish to keep from starving?

There are plenty of stories of castaways on the ocean who starved or resorted to cannibalism.

    The sea is pretty darn big. Some has fish and some does not. Even if it has fish you may not have the right gear for that fish. There is no single answer. Too broad. – paparazzo Sep 26 '18 at 14:56
  • You need to catch only a fish or two, which can be good for food, but possibly not as a water source as explained in the other place you linked. How likely - that's a rhetorical question. – Jan Sep 26 '18 at 16:30

    I voted to leave this open, it seems reasonable to assume that a general statement about, presence of fish in the ocean can be provided, even if that statement only explains why it not practical to give a general answer. – James Jenkins Sep 26 '18 at 17:09

    Despite my previous comment, I would like to point out that the news articles which prompted the recent "adrift at sea" questions was about a boy who survived 49 days at sea on fish, but his raft was actually part of a commercial fishing operation and accidentally detached from it, so the boy was adrift on a commercial fishing vessel even if of a primitive nature. So that event does not work here. – Aaron Sep 26 '18 at 17:26

    @Aaron You are not going to bring in fish you find out in the ocean with cheap or improvised gear. – paparazzo Sep 26 '18 at 18:25
