Physiological mechanisms of imprinting and homing migration in Pacific salmon Oncorhynchus spp.

    Journal of fish biology
  • 2012
Neurophysiological studies revealed crucial roles of olfactory functions on imprinting and homing during downstream and upstream migration, respectively, in anadromous and lacustrine salmonids.

Salmonid Reproductive Migration and Effects on Sexual Maturation

Physiological biotelemetry techniques were applied to examine the homing behaviours of adult chum salmon from the Bering Sea to Hokkaido as well as lacustrine sockeye and masu salmon in Lake Toya, and revealed that salmon can navigate in open water using different sensory systems.

Homing ability and migration success in Pacific salmon: mechanistic insights from biotelemetry, endocrinology, and neurophysiology

  • 2014
Evidence of geomagnetic imprinting has been reported in sockeye salmon Oncorhynchus nerka and been used to explain their migration precision, but there are still many uncertainties regarding which sensory systems play important roles in open water orientation, which hormones control homing migration, and how olfactory systems discriminate among natal stream odors to identify the natalStream.

Mechanisms of homing in salmonids

It is shown that the rates of homing (and straying) vary among species and among populations of the same species, depending on their biological and ecological features, on a variety of environmental factors and conditions, and anthropogenic impact.

A semi-closed recirculating aquaculture system is introduced to estimate the health condition and improve the olfactory imprinting capability of juvenile chum salmon.

Spreading of River Water Guides Migratory Behavior of Homing Chum Salmon Oncorhynchus keta in Otsuchi Bay, a Narrow Inlet with Multiple River Flows.

The present results suggest that homing migration of salmon in the Sanriku narrow inlet is guided by natal river flows.

Insights into Chinook salmon ( Oncorhynchus tshawytscha ) movement ecology in the terminal reaches of the upper Yukon River during the spawning migration

Chinook salmon ( Oncorhynchus tshawytscha (Walbaum, 1792)) from the upper Yukon River are highly unique, with some populations migrating nearly 3000 km to spawning habitat near the northern range

Physiological Mechanisms of Imprinting and Homing Migration of Pacific Salmon

  • 2016
The olfactory memory formation and retrieval of Pacific salmon were investigated using several neurophysiological techniques, suggesting that long-term stability of dissolved free amino acid compositions in natal streams are crucial for Olfactory imprinting and homing, and N-methyl-D-aspartate receptor can be a useful molecular marker for ofalactory memory form and retrieval.

Environmental conditions and physiological state influence estuarine movements of homing sockeye salmon

It is proposed that wind-induced currents exposed sockeye salmon entering the estuary to stronger olfactory cues associated with Fraser River water, which resulted in faster migration rates presumably due to either an increased ability for olfatory navigation and/or advanced reproductive schedule through a neuroendocrine response to olfitory cues.

Variable thermal experience and diel thermal patterns of homing sockeye salmon in coastal marine waters

The factors associated with the thermal experience of homing sockeye salmon in coastal marine environments are more complex than previously thought, and multiple year studies are needed before generalizing behavioural patterns observed from single year studies.



Physiological Mechanisms of Homing Ability in Sockeye Salmon: From Behavior to Molecules Using a Lacustrine Model

Results demonstrate the suitability of the lacustrine model for studying the physiological mechanisms of homing ability in sockeye salmon.

Recent biotelemetry research on lacustrine salmon homing migration

One of the most interesting aspects of the salmon's life history and the most challenging to study is the homing migration during which the fish return from their oceanic feeding grounds to the natal

Homing in Pacific salmon: mechanisms and ecological basis

The mechanisms underlying all aspects of salmon homing are reviewed but the final, freshwater phase governed by olfactory recognition of homestream water is focused on.

Homing behavior and vertical movements of four species of Pacific salmon (Oncorhynchus spp.) in the central Bering Sea

Sockeye, chum, and pink salmon showed strong surface preferences but chinook salmon swam deeper than did the other species and suggested that salmon had a compass orientation ability functioning without celestial information.

Responses of migrating adult sockeye salmon (Oncorhynchus nerka) to population-specific odours

The experiments revealed that the olfactory system of migrating adult sockeye salmon was sensitive to amino acids, and electrophysiological experiments indicated that Sproat Lake sockeyes discriminated between water conditioned by their own population from water conditioning by Great Central Lake sockeye.

Life history strategy and migration pattern of juvenile sockeye (Oncorhynchus nerka) and chum salmon (O. keta) in Japan : a review

The life history strategy and migration pattern of the genus Oncorhynchus reflect an evolution of anadromous fish by which they have acquired anadromy for obtaining food resources in the sea and homing ability for reproduction in freshwater.

Behavioural thermoregulation of chum salmon during homing migration in coastal waters.

A positive correlation between surface swimming of salmon and the presence of cool covering water, which could contain river waters is found, which suggests that salmon tend to be risk-prone when subjected to a high concentration of directional cues.

First record of the at-sea swimming speed of a Pacific salmon during its oceanic migration

The swimming behavior of the chum salmon Oncorhynchus keta was studied for 53 d of its 67 d oceanic migration from the central Bering Sea to the Japanese coast. We provide the first data on swimming

Behavioral Responses by Migratory Chum Salmon to Amino Acids in Natal Stream Water

It is suggested that migratory male chum salmon respond to amino acid mixtures in their natal stream water and appear to be affected by multiple amino acids.

Mechanisms of Migration in Fishes

This book discusses migration in the Open Ocean, migration in Coastal and Estuarine Waters, and the Physiological and Behavioral Determinants of Chemosensory Orientation in Fishes.
