Fished after net sadly got snarled (9)
I believe the answer is:
entangled
'snarled' is the definition.
('entangle' can be a synonym of 'snarl')
'fished after net sadly' is the wordplay.
'fished' becomes 'angled' ('angle' can be a synonym of 'fish').
'after' is a charade indicator (letters next to each other).
'sadly' is an anagram indicator.
'net' with letters rearranged gives 'ent'.
'angled' after 'ent' is 'ENTANGLED'.
'got' is the link.
(Other definitions for entangled that I've seen before include "caught" , "Confusedly twisted" , "Intertwined; entrapped" , "Involved in complications" , "snarled up" .)
