Sure the fork may not have been invented yet, but surely the trident had. Just ask Neptune or Poseidon (the Roman and Greek gods of the sea).
Also, the Roman empire was by large an assimilation of many different cultures. What could have been taboo in some parts of the empire, would/could
have been time honored traditions in others.
Paganism was probably still abundant, even 100's of years after Christ. This could have been ceremonial or ritual in nature. A wealthy sea merchant
for instance may have paid tribute to Neptune prior to a shipment departure, by skewering a delicacy over a fire.
Or simply, a civilized man did not want to soil his fine silk garments with greasy fingers?
