Mean to imbibe half of raki and fish (8)
I believe the answer is:
stingray
'fish' is the definition.
(stingray is a kind of fish)
'mean to imbibe half of raki' is the wordplay.
'mean' becomes 'stingy' ('stingy' can be similar in meaning to 'mean'**).
'to imbibe' indicates putting letters inside (to imbibe can mean to drink or absorb).
'half of' suggests halving the letters.
'raki' halved is 'ra'.
'stingy' going around 'ra' is 'STINGRAY'.
'and' is the link.
(Other definitions for stingray that I've seen before include "Dangerous fish" , "menace in the water" , "Large fish with tail spine" , "Large venomous fish -- it's angry (anag)" , "Fish with venomous tail" .)
