can you use a net to catch the kokanee on the mores creek/grimes creek area?

I have seen a number of people catching the spawning yet landlocked kokanee along Mores creek and Grimes creek, (they're not native american). They said that as long as you "milked" them it was legal. I also noticed that they had a fairly large number of fish, around 20 or so and they were bragging about how many they got the prior day as well. I didn't know them but figured they were locals because they didn't seem to have a vehicle nearby to get plates off of.
