Re: Pictures from the South Holston River
Most stocked or farm-raised rainbows have been selectively bred (genetically engineered) to spawn in the fall. True, wild rainbows normally spawn in the spring, but hatcheries have been selecting for earlier and earlier breeders for a very simple reason. Most stockings have to be ready in the spring. A hatchery fish stocked in March and spawned in October/November could be 8 inches or more by stocking time; whereas a spring-spawned fish would not be ready for stocking until summer. Notice that the instances of eggs in rainbows that are noted on this board are all on regularly stocked waters. Though truthfully, even wild fish will have eggs and milt to varying degrees from fall until spring.
