Gutted conger eel in angler's basket (5)
I believe the answer is:
creel
'angler's basket' is the definition.
(I've seen this before)
'gutted conger eel' is the wordplay.
'gutted' suggests removing the centre (to gut something is to remove its insides).
'conger' with its centre removed is 'cr'.
'cr'+'eel'='CREEL'
'in' is the link.
(Other definitions for creel that I've seen before include "Lobster trap" , "Wickerwork basket" , "Lobster pot" , "Wicker basket for fish" , "lobster basket" .)
