Best way to make gold atm (for my char) - should I continue fishing?

Hello fellow twowers, im currently lvl 30 high elf rogue who had to stop lvling (waiting for my friend to catch up) and I thought about making money to get my riding skill cuz I would not be able to afford it by just leveling. Atm I have 30g and my skills are 150 fishing and cooking, 193 skinning and 130 mining, so far I think it was the best to fish oily blackmouths and great sagefishes, should I still do the same or maybe theres a better way/better mats to farm and sell?
