Hitboxes and spawning for cave fishing

[AngryTrout]

In 2 of the caves, where you can catch the orokin type of fish, there's massive hitbox and spawn issues.

Most of the fish, spawn inside of the walls, without them ever leaving their safe space. If they do spawn in the ponds however, you can't catch most of them, because your speak will just bounce right back, because of the hitboxes, from the structures within the pond. 

The red parts, are the zones where the spear will just bounce back.
So the structures, shouldn't have that big of a hitbox.
Here's an imgur link for the pics that might help.
