Trout, Rainbow

Rainbow Trout
Oklahoma Distribution: 

Yes! Oklahoma has two introduced species of trout — rainbows and browns, with rainbow trout being far more abundant. Rainbow trout are native to the cold streams west of the Continental Divide but have been introduced here and elsewhere. The brown, or German brown trout is originally from Europe.  Browns are stocked periodically in the Mountain Fork River below Broken Bow Lake and in the Illinois River below Lake Tenkiller.  Rainbows are stocked approximately every two weeks at all eight of the state’s trout areas during the designated trout seasons.

Description: 

Oklahoma's two trout species can be easily identified.  First look at the side of the fish.  A brown trout will have orange and red spots, but a rainbow trout will be iridescent.  The brown trout will have few or no black spots on its tail and a creamy belly.  In comparison, the rainbow trout will have black spots on its tail and a white belly. 

Habitat: 

Trout tend to seek out and congregate in calm waters. So when fishing in swift waters, cast your bait above exposed boulders and let it drift down through the calm water on the downstream side of the outcropping.

Natural Food Sources: 

Rainbow trout feed on a variety of living organisms including insects, crustaceans, mollusks and fish.

Spawning: 

Eggs are laid in shallow nests dug out by the female in gravel riffles. The eggs require continuous oxygenation at temperatures around 55°F, the eggs hatch about 21 days after they are laid.  Natural spawning of rainbow trout has been documented in the lower Mountain Fork River. 

Facts: 

The key to putting rainbows on the stringer is light tackle. An ultra-light rod and reel spooled with six-pound or lighter line will produce more strikes and provide exciting action. Like all trout, rainbows have definite feeding periods which may begin and end suddenly. There are days, though, when it seems they feed for hours. However, early morning and late afternoon are favored times and most trout are caught during these periods. On streams, larger fish are likely to be found in deep pools while smaller rainbows feed in shallow riffles. Trout face upstream to wait for mayflies, caddis flies, stoneflies, dobsonflies and dragonflies to appear above them. When heavy insect hatches are on, you may see evidence of feeding trout by circular rings or riseforms on the water’s surface.

If you don’t detect riseforms, you may want to switch to wetflies or nymphs. Feeding habits dictate what works and what doesn’t and there are times and places when only flashing spoons, marabou jigs or spinners work. Bait anglers can tempt rainbows by using whole-kernel corn, cheese, salmon eggs and worms on small (sizes 10 to 18) single or treble hooks.

Those preferring the challenge of artificial lures will find small spinners, spoons and marabou jigs are most productive. Using artificial flies is an effective way to catch hungry trout on a fly rod.
