Annual Report of the Fisheries Research Board of Canada for 1961-62 covering the activities of the Technological Station at Halifax, Nova Scotia and the Technological Unit at St. John's, Newfoundland under Director D.R. Idler. The introduction highlights progress across studies on non-bacterial spoilage of ground fish, preservation of fresh fish using chlortetracycline, multi-stage molecular still work, investigations for cod and marine lipids, and ongoing efforts to improve raw-material definition through controlled handling and environmental-variable studies.

FAQs

What stations and units are covered in the annual report for 1961-62?

The report cites progress on studies related to non-bacterial spoilage of ground fish and multi-stage molecular still work referenced through committee summaries (e.g., Summary No. 40 and Summary No. 13).

What new facilities and equipment are mentioned as being added or operating?

It stresses the need to control environmental and physiological variables affecting product quality across fresh, frozen, salted, smoked, meal, and other preservation forms.
