Dear Brian,
There are very few archaeological finds of swordfish in the Ancient
Mediterranean and, to my acquaintance, none from post-Roman times. I also do
not think there is anything published on the size of swordfish
-archaeological or not- in the historical literature, although I suspect
that papers on fisheries must have data on size for certain areas.
As far as I know, swordfish is an open water, migratory species thus,
although one may speak about "stocks" in terms of fishing, I suspect there
must exist a lot of introgression among stocks so that speaking about
"populations" might be a bit misleading.
But the truth is that I just don't know.
It is for this reason that I'm ccying my reply to the ZOOARCH mailing list,
a wonderful group of scholars knowledgeable in just about anything that
relates to animals, who may supply further feedback on the subject.
Greetings,
Arturo

Asunto: Swordfish in Mediterranean Sea
Dear Dr. Morales,
I have received your name and email address from a colleague, Tønnes
Bekker-Nielsen. I am looking for some historical information about sizes of
swordfish caught in the Mediterranean Sea, and had asked Tønnes about it.
He suggested I contact you as you might have some papers or observations
about this.
I have noticed that the Mediterranean swordfish is smaller and reaches
smaller maximum sizes than those from the Atlantic. This is based on
"contemporary" data, e. G., from the last 2-3 decades or so. I am
wondering how large swordfish were in the Mediterranean anytime before the
1900s and if the sizes caught have declined.
Would you have any findings about this, based on your arcaheological or
other studies? If you have any information or papers that contain size
information, I would be pleased if you could send me pdf versions of papers
or links to them.
I thank you in advance for any assistance you might be able to provide.
Sincerely,
Brian MacKenzie
