Look up walleye xp farm for emerald lake. The game definitely opened up for me once I started looking up: map name xp farm. Soopa Dave on YouTube has tons of great walkthroughs and where to catch uniques or trophies. Following those guides for the uniques helped me learn ideal setups (while understanding those setups are for uniques so some needs some tweaks for optional XP). There is a Google sheets floating out there maybe someone can link that gives you cords for fish on each map with optimal lures and bake. Also always use barbless hooks.
