Monthly samples of winter flounder taken in Long Pond from Nov 1962 to Oct 1963 indicated that the flounder moved into deeper water (7-10 m) during the summer and returned to shallow water (1-2 m) from Sept to June. These movements corresponded to the end of the spawning season and the ripening of the gonads respectively. Spawning occurred from March until early June, most of it in May and early June. Most males were mature at age 6 and most females at age 7. 50% of the males and females were mature at 21 and 25 cm respectively. The growth rates of the males and females were similar until the age of 8, after which the females apparently outgrew the males. Early growth and fecundity were similar to those reported for other areas. No feeding took place in Dec or Jan but the flounder fed in March and continued to feed throughout the summer; good intake decreased in the fall. They were omnivorous and the type of food eaten varied with the locality. Polychaetes, plant material, and molluscs were the most common food items throughout the year. Capelin eggs and fish remains were found only during a few months of the year but were eaten in great quantities.
