Approach right for fisherman (6)
I believe the answer is:
angler
'for fisherman' is the definition.
(angler is a kind of fisherman)
'approach right' is the wordplay.
'approach' becomes 'angle' (as in a journalist's approach to a story).
'right' becomes 'r' (common abbreviation).
'angle'+'r'='ANGLER'
(Other definitions for angler that I've seen before include "A rod and line fisherman" , "One hoping for a catch" , "Strait; -- of Lochalsh" , "Fisher with hook and line." , "Hook and line fisherman" .)
