Land a fish (4)
I believe the answer is:
chad
I believe this clue is a double definition.
'land' is the first definition.
(Chad is an example)
'a fish' is the second definition.
(I've seen this before)
(Other definitions for chad that I've seen before include "article put out by Punch?" , "foreign land" , "small piece forcibly removed" , "Country - which got Bush elected in Florida?" , "Small piece that's removed when a hole is punched, in a card say" .)
