Taste our fresh fish (3,5)
I believe the answer is:
sea trout
'fish' is the definition.
(sea trout is a kind of fish)
'taste our fresh' is the wordplay.
'fresh' is an anagram indicator.
'taste'+'our'='tasteour'
'tasteour' with letters rearranged gives 'SEA-TROUT'.
(Other definitions for sea trout that I've seen before include "One angled" , "Something fishy here" , "Salmon-like fish that also migrates from salt to fresh water" .)
