All of the water around Shadowfall is fishable, you can purchase a fishing rod from the main store and equip it, go into mouselook and face the water and left mouse button to cast, You may catch a number of fish or marine life or you may get nothing, occasionally the rod will break and you will need currently to replace it. (Fixing should be coming soon!)
The fish can be cooked along with farmed materials to make stamina meals, more on that in cooking!
For residents that have rentals on the suburb sims it is possible to also have farming plots to grow crops installed and/or some cattle/chickens all of these obviously provide different ingredients that can be used in the other skills such as brewing and cooking. Do not harvest the crops or animals if it is not your farm. It is against the law and a ban-able offense.
Scattered around the sims are Fruit trees and bushes, these can be picked for fruit baskets that can be eaten to regain stamina, free and easy way to recharge stamina.
