Rainbow Trout

Hard-fighting and acrobatic, rainbow trout are the mainstay of UK stillwater fly fishing. Stocked in lakes and reservoirs nationwide, they provide accessible fly fishing for all levels and are more forgiving than wild browns.

Tackle that suits

Detail
Hooks 8-14. Barbless lure and nymph hooks. Long shank for lures, standard for nymphs and buzzers
Mainline WF6-7. Weight Forward floating or intermediate. Floating for surface work, intermediate sinking for sub-surface
Hooklength 5-8lb tippet. 9-12ft. Copolymer or fluorocarbon leader - less critical than for browns
Shotting Weighted flies (bead heads, tungsten) do the work. Sinking lines for deep water.
Field notes Rainbows are more aggressive than browns and will chase lures and streamers; Buzzer fishing (chironomid pupae) is deadly on stillwaters - fish them static under an indicator; Intermediate sinking lines get lures down to cruising fish in the water column; On bright days fish deeper - rainbows move down in clear conditions; A fast figure-of-eight retrieve with a Cats Whisker is a classic opening tactic; Keep the lure moving on the drop - rainbows chase a fished lure confidently

Fish welfare

Warm water is hard on rainbow trout. The app warns from 18°C and tells you to consider not targeting them at 21°C.

Same welfare profile as brown trout - handle quickly, wet hands before unhooking, avoid prolonged fight.
