Fecundity of Greenland Halibut,Reinhardtius hippoglossoides(Walbaum), from Southern Labrador and Southeastern Gulf of St. Lawrence

The fecu ndity of Greenland hal ibut from the southern Labrador and southeastern Gulf of 51. 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 relationship for the southern Labrador area differed significantly from that for the southeastern Gu If of 51. Lawrence both in the rate of egg production and the number of eggs produced, but no differences were found in the fecundityage relationships. The higher fecundity of fish in the southeastern Gulf of 51. 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.
