Abstract
The significant decline in the abundance of the Greenland halibut Reinhardtius hippoglossoides matsuurae in the Northwest Pacific was one of the impetuses to scrutinize the age determination methods for this species based on different age-recording structures. The present study was carried out in accordance with recommendations of the Northwest Atlantic Fisheries Organization (NAFO) and the International Council for the Exploration of the Sea (ICES). An analysis of age determination data for the Greenland halibut has shown underestimation of age estimated using scales or whole otoliths compared to the technique using otolith sections through the peri-sulcular tuberosity. A resource exploitation strategy based on incorrect age determination can either be the major cause of negative trends in the status of the Greenland halibut stock or have a combined effect with natural factors.
期刊介绍:
The Russian Journal of Marine Biology was founded in 1975 by Alexey V. Zhirmunsky, member of the Russian Academy of Sciences. The Russian Journal of Marine Biology covers a wide range of research and some applied aspects of marine biology as a synthetic science related to various fields of study on marine biota and environment. It presents fundamental research on biological processes at molecular, cellular, organismal, and populational levels in marine organisms. Consideration is given to marine objects as models in life sciences. The journal also publishes papers dedicated to events in Russian and international marine biological science and the history of biology.
