Can't fish in pond
They are not visible and I'm not able to fish them.
[EDIT] You need to place the sign in a deeper area. Solved.

From one screenshot it appears that there are nowhere your sim can stand close to the water.
Hmm, maybe I should have another look at my pond, too. It's basically at the bottom of a slope, so might not have as much flat area around it as I thought. though they have no trouble wading and searching for frogs.
Turns out, the ground was the issue. The nearest flat terrain was either two or more squares back from the pond or on the far side, where my sims couldn't reach. I flatted an area right around the fishing sign, and now fishing works!
