Trout and steelhead love eggs. This is not debatable. I love catching trout and steelhead. That’s not debatable either. What does seem to be debated on occasion is whether or not certain egg imitations are flies, although it's sure hard to argue against their effectiveness. I’m not about to delve into the whole fly-or-not-a-fly thing here, however, I’d like to discuss the effectiveness of egg imitations presented with fly tackle.
My home water is the lower Sacramento River near Red Bluff. In this section of river, there are salmon, steelhead, rainbow trout, and suckerfish, among others, that spawn in these reaches throughout the year. As a matter of fact, with the varying salmon runs alone, there are eggs present in the river in most, if not every, month of the year. Something to consider, right?
Just like fishing bugs, egg imitations should match the hatch, meaning they need to be a similar size, shape, and color to what is already in the water. Fortunately, there is every conceivable color combination under the sun available to anglers when it comes to selecting an imitation egg. Which color you land on should take into consideration what species of fish is dropping eggs at the time, what stage of the egg drop, and whether you want to imitate a live or dead egg. These factors will help decide size and color.
To imitate a king salmon egg, for example, I like sizes in the 8mm to 12mm range. How big I go will often hinge on water clarity at the time. To imitate a fresh egg, I will go with a brighter, more vibrant orange color. To imitate a dead egg, I will go with lighter peach or pearl colors, even delving into a more caramel color.
As far as which fly to select,
