When I go trout fishing I use mealworms and try and find a nice little brook or something with moving water. If you don’t want to use live bait, trout also like lures. Something shiny or something that looks like a little fish. Generally opening day is a little busy but the fish won’t all be gone. Trout need to be a minimum of 8 inches to keep, but that’s still a little small for my taste. I generally try and keep 10-12 inches and up. They cook perfectly on the grill wrapped in tin foil with some lemon and pepper and butter. As long as the river you’re fishing from is deemed safe then you will have no issues eating them. Generally there will be a posting on a sign telling you how many of the fish are safe to eat within a certain time period, at least in my experience.
