Anonymous. Complex movements, philopatry and expanded depth range of a severely threatened pelagic shark, the Oceanic whitetip (Carcharhinus longimanus) in the Western North Atlantic. Our results might be biased by the low sample size, particularly regarding the inconsistent correlation between the North Atlantic subpolar gyre and individual migration routes, meaning that adults’ overall dependency on gyre systems for transportation may differ from our observations at the population level. The on-board geolocation in the LAT-2810 tags provides estimates of latitude and longitude based on both a threshold method and a template fitting method [22]. Maximum diving depths ranged from 324 to 740 m (Table 1). In recent years, pop-up satellite archival tags (PSATs) have been used to map ocean habitat use [7,8,9].

Pop-up positions for post-spawned Atlantic salmon from three Norwegian Rivers indicate that Atlantic salmon from the Alta River utilize these waters to a greater extent than individuals from a central, more southern Norwegian population, but to a lesser extent than Atlantic salmon originating from a river draining directly into the Barents Sea [11]. https://doi.org/10.1139/cjfas-2014-0169.

Hedger RD, Rikardsen AH, Strøm JF, Righton DA, Thorstad EB, Næsje TF. In contrast to diving frequency and diel vertical movements, no consistent seasonal trend was found regarding the mean diving depth.

Previous records of Atlantic salmon in the Barents Sea are derived from end positions from fish tagged with PSATs and retrieval of tags from conventional tagging programs [9, 11, 36]. https://doi.org/10.1111/j.1095-8649.2010.02673.x. Atlantic salmon are an anadromous fish, that begins their life in freshwater and migrates to the ocean to feed and grow, and returns to freshwater to spawn. ICES J Mar Sci. Righton D, Westerberg H, Feunteun E, Økland F, Gargan P, Amilhat E, et al. Technical University of Denmark. In summer, they graze on dense swarms of plankton at the edge of the ice shelf. 2012;116:140–58. Oikos. [7]. 18, 19]. In comparison, for Norwegian Atlantic salmon inhabiting Arctic latitudes, depth use correlated with seasonal changes in light, with individuals spending more time near the surface during the winter polar night [11]. After insertion, the body wall of the fish was pierced using a trocar, allowing the antenna to exit and lie laterally along the fish’s body. After the yolk sac is absorbed by the body, they begin to hunt. This suggests an overall utilization of these waters for various populations and life stages. The diving depth of individuals was significantly correlated with the depth of the mixed layer (analysis of deviance test: χ2 = 99.4, p < 0.001), with individuals diving to greater depths as the mixed layer deepened during winter or spring (Fig. Overall, there was a strong temporal trend in the depth use, and the proportion of time spent in surface waters depicted a seasonally cyclic pattern (Fig. Minor northward displacements occurred with decreased temperatures, whereas when temperatures were increased, positional estimates were marginally south of the original tracks (Additional file 7: Figure S7).

Atlantic salmon, also known as the King of Fish, are anadromous, which means they can live in both fresh and saltwater. We thank the Alta Laksefiskeri Interessentskap and its members, for the necessary assistance in conducting the study. Nature. 2, 3). Large pelagic predators could jeopardize the recovery of endangered Atlantic salmon. In: Aas Ø, Einum S, Klemetsen A, Skurdal J, editors. The tags had a high failure rate, and of the fish recaptured on their return migration, data were only retrieved from six tags, with the remaining four tags malfunctioning due to technical failures. 2017. As with various other aspects of fish life, zoologists have developed empirical classifications for fish migrations. Repeat spawning is common within the population, with most post-spawned individuals entering the ocean during spring and return to the river after spending approximately 1 year at sea [21].

Salmon and striped bass are well-known anadromous fish, and freshwater eels are catadromous fish that make large migrations.

Modelling the migration of post-smolt Altnatic salmon (Salmo salar) in the Northeast Atlantic. Few recaptures may relate to the exploitation rate of Atlantic salmon in the Alta River, which is low compared to many other Norwegian populations [42].
