Hey guys, caught my first perch today thanks to the tips here

it was a small enough one, but hungry, because he swallowed my hook pretty deep, it took me a while to get him unhooked, and when i was putting him back he took a long time to recover, he wasn't dead, but he wouldn't swim away either, ended up putting him into weeds and hoped he'd soon recover

any tips on what i can do to help fish???
