Food fish with a funny nose and a duck's tail (5)

'food fish' is the definition.
(I know that snoek is a type of food fish)

'funny nose and a duck's tail' is the wordplay.
'funny' is an anagram indicator.
'and' means one lot of letters go next to another.
'tail' says to take the final letters.
The last letter of 'duck' is 'k'.
'nose' anagrammed gives 'snoe'.
'snoe'+'k'='SNOEK'

'with a' is the link.
