You seem to have forgotten about the very nice Navigator's Ear. For those of us fishers that are going for the Hamlet fish (young indigo herring) (which is also less likely to be botted due to the fact that you have to move from school to school in order for each to respawn), we find that Navigator's Ears come in abundance. Maybe 2.5 stacks per 2 stacks of Young Indigo Herring. These sell for quite the penny when it comes to the time that the community decides to push for a level 2 hamlet. I recently got 300k for one day of fishing. They won't sell right away though, as you need to wait for people to want the level 2 hamlet (which happens every so often)
