It is exceedingly difficult to procure reliable statistics of the total quantity of fish taken in the British seas. These can only be obtained in a crude way from the fishermen, there being no tally kept by the salesman, except of a rough kind. I made some inquiries into the London fish supply at Billingsgate, but they were unsatisfactory, as there is no register kept there of the quantity sold. Each of the wholesale men can give an idea of the total number or quantity of fish consigned to him; but even if the whole body of salesmen were to give such statistics, it would only, after all, represent a portion of the London supply, because much of the fish required for the London commissariat is sent direct by railway to private dealers. But London, although it requires a very large total of fish, seldom obtains all that its citizens could eat, nor does it by any means get all that are captured, or that are imported. Manchester, Birmingham, Liverpool, and other large towns in England; and Glasgow, Edinburgh, Dundee, and Aberdeen, in Scotland, require likewise to be supplied. And besides this home demand, we send considerable quantities of our white fish to the Continent, especially in a dried or prepared state. The fishermen of the Shetland Isles, for instance, cure largely for the Spanish and other Continental markets. Finnan haddocks and pickled cod can be so prepared as to bear shipment to a long distance, and kippered salmon are found on sale everywhere, as are also pickled and smoked herrings.
