Money in Shark Livers
p. 102 · Read in the full issue
THAT there is money in shark livers of the right type is shown by a report from New Zealand that a shark recently caught off Stewart Island contained a liver weighing 24 lbs. and valued at £l5 Stg., delivered unrendered to the buyers.
The vitamin content is reported to vary widely with different species, however; and, in the case of shark oil produced in the Islands, the yield per shark of the more common varieties is not high and the vitamin content lower than from the cold water types. Great care must be taken in rendering livers to avoid
high temperatures and to extract all water which, if left, will cause the oil to go rancid.
