The fecundity of Greenland halibut from the southern Labrador and southeastern Gulf of St. Lawrence areas in 1976-78 was found to be highly correlated with length and to a lesser extent with age, the relationships being best described in terms of log-log regressions. The fecundity-length relationships for the southern Labrador area differed significantly from that for the southeastern Gulf of St. Lawrence both in rate of egg production and the number of eggs produced, but no differences were found in the fecundity-age relationships. The higher fecundity of fish in the southeastern Gulf of St. Lawrence may be due to their becoming mature at considerably smaller sizes than in the southern Labrador area. Annual variation in fecundity was not evident in the data for 2 years from southern Labrador.
