Leaping trout is a fish which requires 48 Fishing, 15 Strength, and 15 Agility to be caught, providing 50 Fishing experience, 5 Strength experience, and 5 Agility experience. It can be caught at Otto's Grotto or Mount Quidamortem with a barbarian rod and suitable bait after starting talking to Otto Godblessed to start Barbarian Training.
Unlike normal fish these cannot be cooked, instead they are gutted by using a knife on the fish. There's a 48/150 (32%) chance of receiving roe with level 48 Cooking, and 99/150 (66%) chance at level 99, scaling in-between. If the player successfully receives roe, there is a further 1/2 chance they will receive fish offcuts as well. Successfully gutting the fish also provides 10 Cooking experience. The roe and offcuts serve as bait, allowing the player to save some feathers.
Due to the fact that you simultaneously obtain Strength and Agility experience, Leaping trout are a great way to train fishing.
