Good to stop fishes making noises in the throat (8)
I believe the answer is:
gargling
'good to stop fishes making noises' is the definition.
I can't judge whether this definition defines the answer.
'in the throat' is the wordplay.
I cannot really understand how this works, but
'in' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for gargling that I've seen before include "Washing the throat" , "Rinsing the mouth with medicinal fluid, while breathing out through the liquid" .)
