It's hard to say with trout. Many of them at least sink at first. The ones I've lost sink first and them float up a day to three days later. Many never float up.
There was a poster here years ago that planted a pond with rainbows. Never saw any activity all summer and assumed they were dead. Come fall all of a sudden they became active on the surface again.
