Big fish

From Bernard Hassan Sir: King Carlos of Portugal may have published a book on tuna (‘Food for thought’, 21 May), but two other reigning monarchs have published extensively on ichthyological questions in marine biology journals. They were/are the Showa Emperor (i.e., Hirohito) and his son, the present emperor of Japan, Akihito. I lack the competence to judge whether the articles were accepted because of their learning or because of their source.
