I always just use Parata's Peace to grab my map for the day before I do any other fishing. Nothing's going to aggro me and I can stand right in the water so I know I'm in the right spot. Always fish up a map within the first five casts using a rainbow spoon lure. If you catch some trash before it, just sell to the vendor in Vesper Bay and then scoot right on along to wherever else you plan to hit for the day.
