The Faroe haddock appears to be on the whole richer in flesh than the .Shetland or North Sea fish, and it does not lose con- dition after spawning, so much, or for so long a period as the fish from the two other re< Fig. 3. The spotted haddock was, I am informed, unknown in Aberdeen seventeen years ago, and one gentleman who cured haddocks on the west coast of Shetland (Walls, Scalloway) twenty-five years ago did not know them. It is said however, that defective haddocks, possibly spotted, had been sometimes taken twenty-five years ago in June in nets which had sunk to the bottom with weight of herrings, between Ve Skerries and Blue Mull Sound. The affected codlings exhibit coiled nematodes scattered singly through the muscles: they are taken at Faroe, Rona and Rockall: especially in the first-mentioned fishing region. At present it is believed.
