Assessing changes in age and size at maturation in collapsing populations of Atlantic cod (Gadus morhua)

Hepatic EROD activity in dab Limanda limanda the German Bight using an improved plate-reader method
(Journal article; Peer reviewed, 1992-12-31)During the Bremerhaven Workshop an improved, fast and easy method for the determination of ethoxyresorufin-O-deethylase (EROD) activity in dab Limanda limanda liver was tested. The improvement involved the use of a 12500 ... -
Implications of density-dependent juvenile growth for compensatory recruitment regulation of haddock
(Journal article; Peer reviewed, 1999)Data from bottom trawl surveys conducted by Canada and the United States were used to describe temporal trends in the length of haddock ages 1–4 on the southwestern Scotian Shelf (SWSS) and Bay of Fundy. From 1970 to 1995, ... -
