'Swim' used by an angler? (4)

I believe the answer is:

reel

I'm a little stuck... Click here to teach me more about this clue!

'swim' is the definition.
(I've seen this before)

I can't explain the remainder of the clue.

(Other definitions for reel that I've seen before include "Stagger around in the dance" , "Folk dance" , "The angler pulls in his line using this" , "Show astonishment" , "unwind?" .)

I've seen this clue in the Evening Standard.
