Fishing still offers a nice steady income.
I've recently returned to the game my self, and if anything prices seem to have gone up on a lot of fish in my absence (I havent seen a single rmt fishbot since I returned, so I'm guessing its because there is less flooding of the AH and less undercutting going on).
Obviously not all fish have risen in price, it varies from fish to fish. For example when questing my Lu I used to buy 3k/stack moats from the AH, nowadays they are selling very fast at 8k/stack on my server. Whilst Nebs are down to 10k whereas iirc they were selling at around 15k when I quit.
The good thing with fishing is its always in demand by Alchemists and Cooks, two tradeskills that mainly deal in consumable items that are always in high demand, wheras other tradeskills have gone stale these past few years.
