2Ó00 for ihe grey seal stock. Since then some biological and statistical data have been collected by the Icelandic Fislieries Laboratory and the Marine Researcli Institute, Reykjavik. The latest stock size figures show 40—45000 individuals of common seal and 8—10.000 grey seals. Seal hunting in Icelandic waters dates back to the settlement of Iceland. Records of seal hunting span the period front 1897 till present. For historical reasons no form of licence or catch quotas have been introduced up to now. The hunting statistics sliow that the mean annual catch in tlie years 1897—1919 was about 6000, then tlie catches declined reaching minimum between 1939—1959. In 1960 the catches suddenly increased again and have since been about 5000—7000 ani- mals per year, except for 1978 when it dropped to 4623, because of a sudden lall in skin prices. The decline in hun- ting after 1919 was probably not due to overhunting, but more like to changes in habits of the Icelandic people, an epidemic in both seal populations, un- favourable prices etc. The damage to the fishery industry caused by the cod- worm is enormous and because of the connection between the seal and tlie cod-worm it has been suggested that seal research should be increased to get proper answers to many questions concerning thc biology of the Icelandic seal stocks.
