Spawning trout


We love wild trout

We love naturally recruiting trout or wild trout.  In the Green, the brown trout (fall spawn) are 100% wild, so if you catch a brown in our system, you know it is wild.  The Rainbows & cutthroat (spring-early summer spawn) are a mixed bag of hatchery hold over fish and wild fish. During the spawning periods, a mature male and female will clear off shallow gravel bars with their tail & ventral fins (tans spots pictured above are brown trout redds) and simultaneously deposit sperm and eggs into the tan spot or redd.  Most of the time, redds are located in shallow water and easy targets for anglers & eagles/osprey. These fish can spend days of digging to get the final moment of egg fertilization and deposit, making them extremely vulnerable to anything that wants to catch or kill them. The eggs will incubate for over a month in the redd and if they don't get crushed by wading anglers, shifting gravel during runoff or boat anchors, the fry will hatch and have a long journey of survival before they grown big enough to eat your fly.  The Wyoming Game and Fish believes that each egg has less than 1% chance of survival.  Very important and fragile point in a trouts' life right here...   


Walking in spawning areas = crushed trout eggs

Seen above are a bunch of irresponsible anglers on the Green in the spring of 2018.  They walked all over this redd, not knowing they were crushing all the fertilized eggs the rainbows worked so hard to safely get in the ground.  If you see spawning trout, it is best to avoid wading that area and fishing to them.  Take pictures, have lunch and enjoy the show the fish are putting on.  It's pretty neat to sit and watch!  


Saprolegnia & Furunculosis

 It is a known fact that targeting spawning fish promotes the white fuzzy growth of Saprolegnia on Rainbows/Cutties and Furunculosis on Brown trout. We have this every season on our spawners and it can often be seen as soon as the fish on the redd is noticeable. The additional stress of being hooked/caught promotes both of the bacterial infections. Rainbows are known to fight off Saprolegnia, for brown trout, furunculosis is typically fatal. Further, both Sapro/Frunk are transmittable to the redd full of fertilized eggs and often kills the entire nest of eggs.  Hear that? Kills the entire nest.  If you enjoy catching naturally reproducing fish, then it is best to not promote these diseases and let the fish spawn.  This means, don't fish to the spawners.
