Dragged fishing net (5)
I believe the answer is:
trawl
'dragged fishing net' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for trawl that I've seen before include "Use net" , "Drag a large net" , "Catch" , "search for a suitable appointment" , "(Fish using a) dragnet" .)
