Abstract

Fecundity is described for Greenland halibut, based on ovaries collected in July 1997 in ICES Division XIVb in East Greenland waters. The mean potential fecundity was estimated to be 113700 (range 32500–277100). Fecundity was significantly determined by total length. Fecundity–length and fecundity–weight (round and gutted) relationships were estimated. Vitellogenic oocytes appearing dark in the microscope with a diameter ranging from 900 to 1650μm were counted and used in the fecundity estimates. This stage was easily distinguished from an early vitellogenic stage, with a diameter ranging from 490 to 1050μm (mean 730μm). The latter appeared transparent with a small brownish nucleus.
