An extract from Morris, L., 1748. Plans of Harbours, Bars, Bays and Roads in St. George's Channel. The extract (page 52) describes an ancient fishery, for turbot and codfish, off Milford Haven.

The extract reads as follows: “ On the Porgus Bank, which lies about Two Leagues S.W. of St Anne’s Light-houses, they had in ancient Times a great Fishery of Turbot and Codfish; and it is remarkable, that though this dangerous Bank was always known to the Fishermen of Milford, that it was never laid down, nor a Word mentioned of it, in any Chart or Description of this Coast, till now.”
