Yes And Yes to your ?s
A trout has to assimilate to its new environment to survive,ie food source ,bugs,forage fish etc. The trout will change in appearance also,the fins will grow out,the color will change a bit to match the new environment.If you ever catch a holdover fish and look closely at it you can see the difference compared to a freshly planted fish.
