The researchers first quoted in your article (Romans had whale industry, research suggests, 11 July) have made a very bold extrapolation from very small evidence. I would agree with Dr Erica Rowan, cited towards the end of the piece, that one might expect documentary evidence if the Romans actually had a whaling industry. Far more likely they merely exploited any drift whales (dead whales found floating or cast ashore).
Right whales (so called because they were the right whale to catch, being slow-swimming, floated once killed, and had a thick layer of blubber and a mouth full of baleen) certainly were exploited in the post-Roman period, and the Biscayan community had been rendered extinct by the Basque whalers by medieval times.
The right whale community off the north-east coast of the United States was so depleted that genetic studies of the current stock suggests that it was reduced to only five females at one point. Only the decline of the US industry enabled them to survive.
