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

'fishes' is the definition.
(haddock is a kind of fish)

'possessed landing places' is the wordplay.
'possessed' becomes 'had' ('have' can be a synonym of 'possess').
'landing places' becomes 'docks' (dock is a kind of landing place).
'had'+'docks'='HADDOCKS'

'for boats getting' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
