Choose fish for preserving (8)

I believe the answer is:

pickling

'preserving' is the definition.
(pickling is a kind of preserving)

'choose fish' is the wordplay.
'choose' becomes 'pick' (picking is a kind of choosing).
'fish' becomes 'ling' (ling is a kind of fish).
'pick'+'ling'='PICKLING'

'for' is the link.

I've seen this clue in the Sydney Morning Herald.
