The Reproduction of the Edible Crab (Cancer pagurus)
Published online by Cambridge University Press: 15 September 2014
Extract
During the last two winters I have had considerable opportunity of making observations on the reproduction of the edible crabs of the Northumberland coast; and though, my results are still incomplete, and some of them, as, for instance, those relating to the size of sexually mature crabs, are chiefly of local importance, I think the meagreness of past work on the subject, and its practical importance in connection with fishery legislation, justify me in publishing some account of what I have seen.

But a Beadnell man has got some definite results of labelling experiments for me: two crabs out of twelve that were marked and liberated at the shore in December 1892 were recovered in 1893,—one in March, 1½ miles out; the other in April, fully 3 miles from the coast. Another, labelled in December, and put into the sea 2 miles out, was recovered in July close to the beach.
