“…The vertical movement by Greenland halibut was not related to diel cycles, which is consistent with the results of stratified random bottom and pelagic surveys (Jørgensen 1997a). The estimated swimming speeds (steep ascents and descents) throughout the depth record were largely not indicative of rapid vertical movements into the pelagic water column potentially to feed as has been reported for Greenland halibut in the Northeast Atlantic (Vollen & Albert 2007, Albert et al 2012.…”

Little is known about the movement of Arctic marine fish, particularly benthic species, despite growing pressure from commercial fisheries and a changing climate. The Greenland halibut Reinhardtius hippoglossoides lives in the deep, cold waters of the Arctic, North Atlantic and Pacific Oceans where it represents an important commercial fish species and a significant prey resource for whales and sharks. To investigate movement, depth and temperature preferences of Greenland halibut, 9 large (83 to 95 cm fork length) individuals were tagged with pop-off archival transmitting tags in Cumberland Sound, Baffin Island in August 2010 to record data for 70, 100 and 300 d. While all tags reported back, 7 tags provided the bulk of the data, transmitting (mean ± SD) 67 ± 7% of the data collected. Greenland halibut exhibited strong site fidelity to localised deep areas (900 to 1400 m), but ranged between ~400 and 1400 m, with all tags poppingoff within 27 km of the tagging location. Mean depth was 1048 ± 112 m (n = 7) during the ice-free season and 823 ± 121 m (n = 2) during the ice-covered season. Temperature occupied by Greenland halibut from August until June ranged from 1.3 to 2.7°C (mean ± SD: 2.2 ± 0.01°C). A mixedeffect model found preferred depth did not vary within a diel cycle, but did change among months. Seasonal movements coincided with ice cover, but further work is needed to clarify this relationship and determine the extent and timing of these movements within and beyond Cumberland Sound.

Understanding how the characteristics of Arctic marine ecosystems relate to fish movement patterns (i.e. linking environmental parameters with the distribution and abundance of fishing resources) is of critical importance for the management and conservation of Arctic marine fish stocks (Schick et al. 2008).Satellite telemetry has been used to study the movement, behaviour and environmental preferences of a wide range of aquatic species, including sharks (Sims et al. 2003, 2008, Teo et al. 2004, Brunnschweiler et al. 2010) and many teleostei, such as tuna (Block et al. 2001, Kitagawa et al. 2004, Schaefer & Fuller 2004 and flatfishes (Seitz et al. 2003, Loher & Seitz 2006, Loher & Blood 2009). These tags are attached externally to the fish, during which time they record depth, temperature and light, and release after a specified length of time, thus providing insight into horizontal and vertical movements and habitat use over different spatial and temporal scales (Block et al. 2001, Wearmouth & Sims 2009, Humphries et al. 2010. There is no requirement to recapture tagged individuals, making this technology particularly useful for studying fish in deepwater habitats and extreme environments, such as the Arctic, wher...

“…The percentage of empty stomachs (PES) was used as a measure of feeding intensity in accordance with previous work (Junquera, 1995;Rodríguez-Marin et al, 1995Jørgensen, 1997). The relative importance of individual prey taxa was assessed in terms of percentage frequency of occurrence (FO), percentage by number and percentage by weight (Clark, 1985), and by using the mean partial fullness index (PFI) as described in Lilly and Fleming (1981).…”

“…R. hippoglossoides is however known to perfoffl! extensive vertical feeding migr~tions in West Greenland waters CC:hristensenand Lear 1977; Jørgensen 1997), but this has not been reported from the eastem Norwegian Sea and the fish observed pelagically by Jørgensen (1997) were rarely more than one year old. Michalsen and Nedreaas (in press) conclude that adult R. hippoglossoides also leaves the bottom to feed on pelagic organisms such as herring in the water column in the , western Barents Sea.…”

“…Several studies of the diet of this species have been carried out in the western Barents Sea/north-eastem Norwegian Sea (Nizovtsev 1969;Haug and Gulliksen 1982;Shvagzhdis 1990;Michalsen and Nedreaas, in press), off West Greenland (Pedersen and Riget 1993;Jørgensen 1997), in Icelandic waters (Paschen 1968;Skuladottir and J6nsson,1991) and in the north-eastem Atlantic (Bowering and Lilly)992),while information on diet in the eastem Nof"(egian Sea south of 71 °\'< is SCllfCe. The general impressimt fromthese studies is that Greenland halibut is piscivoro~s but also to same :degree feeds on shrimps and cephalopods.…”

In June 1995 and 1996 demersal fishes on the continental slepe of the eastem Norwegian Sea were sampled to study distribution pattems and community structure. The diets of the more abundant slepe species were characterised and linkages within the upper slepe food-web identified.Few cases of predator-prey relationships between the typical slepe fishes were found. Most of the smaller fishes fed on epibenthic crustaceans such as amphipods and mysids, while pelagic crustaceans and fish dominated the diets of larger fishes. Herring ( Clupea harengus) and blue whiting (Micromesistius poutassou) were important prey items of Greenland halibut (Reinhardtius hippoglossoides), and were also eaten by Lycodesfrigidus, Raja hyperborea and roughhead grenadier (Macrourus berglax). At !east for the latter three species this probably reflected scavenging.
