Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations Salmon in my pond

I recently released around 500 pink salmon frye in my pond, if i do not let them escape will they live in my pond or do they need to go out to the see, my pond has a stream leading to a large river which then leads to the ocean, the other end of the stream goes to another pong about a quarter mile away could these salmon survive here or should i let them go to the sea.
