Sexual maturity cycle and spawning of Greenland halibut Reinhardtius hippoglossoides in the Davis Strait
Female sexual maturation cycle and the main spawning time of Greenland halibut Reinhardtius hippoglossoides in the Davis Strait were studied through regularly collected samples during 1 year starting in spring 2003. Samples were collected from the southern slope of the Davis Strait Ridge between Can...
