Technically, 16sqm is all you need. (just enough to rez the server). Of course, people will be standing on other plots if you did this.
Practically, even a 512sqm plot could hold a small usable fishing area, whether you're using prim water or Linden. (Linden water is easier, of course, and saves prims. And you don't actually need water, of course).
