Fisherman's need
I believe the answer is:
bait
'fisherman's need' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for bait that I've seen before include "Food to entice fish; taunt" , "Annoy; enticement" , "Boilie, for example" , "Angler's lure for fish" , "Food on a hook to attract fish" .)
