Then you'll have a salmon fishery right where you release them...are you going to release them in a freshwater creek/stream/river?
What species of Salmon are they...Atlantic/coho/Chinook/kokanee/chum/sockeye?
Those bags of food look like purina salmon chow, really is such a thing...
This is great because Salmon is a terminal fishery...meaning when they spawn it is at the end of their life cycle...they can go out to the ocean and when the mature they can return 1000's of miles right back to the place that you release them...
Another interesting fact...the Salmon that were native to the rivers and streams around Mt St Helens, when their natural habitat was destroyed by the volcano, they were found in streams nearest to their home spawn beds, but not necessarily the closest by actual miles traveled, but as the crow flys...All this from an animal with the brain the size of those eggs you're hatching and less than 5 years old...
I was involved with the local high school fisheries class in Westport Wash. And the kids just loved the fact they got to see results from the spawn they released...
Great Job for exposing them...it can only bring light to how delicate our environment really is...KUDOs, we need more teachers like you...
