There are roughly 250 Lochs and Lochans in the Galloway Forest Park, so you don’t have to walk far to find one.
A 10-minute walk from the Dome takes you to the edge of Loch Bradan which is stocked with Brown Trout. Permits can be purchased from Straiton Stores for Loch Bradan and Linfern which are both in walking distance. Linfern is good for Pike fishing.
For Sea Angling there are Day trip boats running out of the town of Girvan, which also do day trips out to the Island of Ailsa Craig.
