Sriguru Shukraacharya was from the lineage of Great Maharshi Bhrigu. Hence he was called "bhArgava". Bhargava pravara is related to many gotras. I am posting the gotras which have bhargava pravara so that it can help you in finding the right gotra. Bold are the gotras and next to them are the pravara. Most probably the first one would be your gotra. But please verify the information from elders before accepting it.
Bhargava: Bhargava ,Tvashta,Vishvarupa
Jamadagni: Bhargava, Chyavana, Aapnavaana, Aurava, Jaamadagneya
Vatsa: Orva,Bhardwaj,Bhargava, Chyavana, Aapnavan
P.S: The above mentioned gotra are mostly brahmin gotra. But for non brahmin's the apt gotra would be brArgava.
