Play the AH! For example, when I first started the game I would buy "sinking minnows" from the fishing shop on the "Mhuara-Selbina" ferry for about 700gil and than sell them on the AH for anywhere from 3000-4000 gil. They sold relatively fast and in a good week I could make about 60k+ doing this. But this is highly dependent on your server and the demand from players. Some weeks I would be unable to sell as many as I would in a good week. Thing w/ sinking minnows is that most players don't want to take the time to wait or travel to catch a ferry to buy sinking minnows. They'll gladly pay an AH price to "save" time.
