I think it would be cool if there was a new fishing profession, similar to mining or hunting. With all the lakes, pools, etc, I think you could work out a system for decay on a rod/line, fish weight, food and crafting (Jori Sushi anyone? ). Given the more natural approach, I feel like it would work well into the atmosphere of Arkadia, and would help to give Arkadia more self identity through another fun and engaging activity that is different from the other planets. The piers are usually for boats, but can't we fish from them too? .
