✦ Synopsis

The present paper presents the results of a study of the oxygen consumption of developing eggs of Salmo salar up to the time of hatching. The work was carried out at Dalhousie University during the winters of 1947-50, making use of eggs supplied by several hatcheries in Nova Scotia. The eggs were reared either in running city tap water or in constant temperature tanks in which the water was mixed by aeration and stirring. The mortality of eggs reared in the constant temperature tanks was high, and for that reason the records of attempts to examine the effect of temperatwe on respiration have been for the most part omitted from the present paper. Unless otherwise stated, the developmental and experimental temperature was 10°C.
