Using rod, possibly getting river fish (6)

I believe the answer is:

poling

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

'using rod possibly' is the definition.
I can't judge whether this defines the answer.

'river fish' is the wordplay.
'river' becomes 'po' (Italian river).
'fish' becomes 'ling' (ling is a kind of fish).
'po'+'ling'='POLING'

'getting' is the link.

Can you help me to learn more?

I've seen this clue in The Telegraph.
