I drew a centre line along the top of the trout from front to back. The same on the bottom. On the trout's left side, I drew a line from the mouth to the centre of the tail. These lines mark my high points and I have been rounding the fish by removing wood between these lines. Towards the middle of the fish, the line on the left is placed a bit higher than the centre of the fish, because that's where the fish is thickest (not in the dead centre).
