That's a discraceful way to handle any fish!
What's he trying to prove?
Taking lot's of photos' just so he can put a weight on the fish!
It's a skinny fish as can be seen fron the head-on shot, size was probably about 7 lb's.
No unhooking mat!
Caught out of season from when the pictures were taken?
At least 4 minutes between the photos.... with the fish probably laying on the ground for even longer!
A total lack of care for the welfare for the fish!
Barbel usually fight to exhaustion, and then it was out of the water for over 4 minutes.... did it die?
