Succeed with fish: about ten caught (5)
I believe the answer is:
excel
'succeed' is the definition.
(I've seen this before)
'fish about ten caught' is the wordplay.
'fish' becomes 'eel' (eel is a type of fish).
'about' is an insertion indicator.
'ten' becomes 'X' (Roman numeral).
'caught' becomes 'c' (cricket abbreviation).
'x'+'c'='xc'
'eel' going around 'xc' is 'EXCEL'.
'with' acts as a link.
(Other definitions for excel that I've seen before include "Do exceedingly well" , "cap" , "Do really well, outshine others" , "Distinguish oneself - XL" , "Perform extremely well" .)
