Stone-scale Eels grant extra armor when used by alchemists to brew
Fire-fin Snappers are another valuable asset to a fisher as they are needed by alchemists to make potions that grant resistance to fire. You may catch these wondrous Anarchy credits creatures in Booty Bay and Strangle-thorn Vale, in Wetlands, and even Azshara.
Like Deviate Fish you should be able to capture one once in about every 5 casts within these areas. These fish sell for around 2-6 gold per stack of 20.
Stone-scale Eels grant extra armor when used by alchemists to brew some potions after being made into oil for the potion. Feralas is the prime fishing spot for these and as the other two above they are fairly easy to catch. They sell for 10-20 gold per stack of 20.
Oily Black-mouth is a fish that can be caught early on and sells between 1-4 gold per stack of 20. There are schools of Oily Black-mouth in Dark-shore, Ratchet, Westfall, and Wetlands. These are needed by alchemists to produce items like Elixir of Water Breathing.
Pearls, magnificent jewels of the deep, can also be captured through fishing. This can be a way to turn a lot of gold since fishing can also yield clam which could contain a black pearl or even a golden pearl.
Winter-spring and Feralas seem to be prime locations for clam fishing and with the Feralas location also having the possibility of Stone-scale Eels you could have the gold piling up in no time.
