To some fishermen using egg fly patterns is not true fly fishing. However, if you are imitating the natural food of your target fish then this is fly fishing. The art of matching the color and size that are being eaten is an art form just like matching the hatch of emerging dry flies, so these are matching a natural food! Not all fish eggs are the same colours.
Techniques for Using Egg Flies
These are popular patterns for Rainbow Trout, Brown and Brook Trout, and Salmon. Eggs are a great source of energy for feeding fish. These flies will catch fish consistently in rivers, lakes and streams throughout the world. Fish on a "dead-drift" in streams, they will fish well against the river or stream bottom, add a couple of split shot to keep it near to the stream bed where the bright colours can attract fish where they make look like a natural egg floating.
On lakes or reservoirs these flies can be floated or used as part of a tandem rig with for example a buzzer suspended below the egg fly at 18" to 24" deep.
Do They Work?
Of course they work! many anglers believe Rainbow Trout especially to be unable to breed and therefore do not produce eggs. This is a misconception as we have seen when fishing, you will see the eggs from a Rainbow Trout in the photo here, match the hatch using orange coloured eggs with that destinctive dot. We have caught female Rainbow Trout in lakes and reservoirs that have been egg laden as you can see from the photo our these Rainbow Trout Eggs. We have watched Rainbows and Brownies hammering the edges of lakes to get at the previously laid eggs planned to hatch in margins, indeed they become so pre-occupied with eggs that there are times when they will eat nothing else!
