I'll just post an excerpt of the poem "The Fish" by Elizabeth Bishop. The excerpt would show that the fish has given up struggling for survival after living a hard life.
"I caught a tremendous fish
and held him beside the boat
half out of water, with my hook
fast in a corner of his mouth.
He didn’t fight. ⇒ The fish gave up
He hadn’t fought at all. ⇒ struggling for survival
He hung a grunting weight, ⇒ after living
battered and venerable ⇒ a hard life
and homely. Here and there
his brown skin hung in strips
like ancient wallpaper,"
