Olfactory Imprinting of Amino Acids in Lacustrine Sockeye Salmon
Juvenile salmon have an olfactory ability to imprint their natal stream odors, but neither the odor properties of natal stream water nor the imprinting timing and duration have been clarified as yet. Here we show, using electrophysiological and behavioral experiments, that one-year-old lacustrine sockeye salmon (Oncorhynchus nerka) can be imprinted around the stage of parr-smolt transformation ...
متن کاملGeomagnetic imprinting predicts spatio-temporal variation in homing migration of pink and sockeye salmon.
Animals navigate using a variety of sensory cues, but how each is weighted during different phases of movement (e.g. dispersal, foraging, homing) is controversial. Here, we examine the geomagnetic and olfactory imprinting hypotheses of natal homing with datasets that recorded variation in the migratory routes of sockeye (Oncorhynchus nerka) and pink (Oncorhynchus gorbuscha) salmon returning fro...
متن کاملEnvironmental conditions and physiological state influence estuarine movements of homing sockeye salmon
The reproductive migration of anadromous salmonids through estuarine waters is one of the most challenging stages of their life cycle, yet little is known about the environmental and physiological conditions that influence migratory behaviour. We captured, sampled tissues, tagged and released 365 sockeye salmon (Oncorhynchus nerka) homing through inner coastal waters towards the Fraser River, B...
متن کاملAttraction of migrating adult sockeye salmon to conspecifics in the absence of natal chemical cues
Directed animal movement, which drives behaviors such as natal philopatry or dispersal, is guided by the input of sensory information. Anadromous salmonids are philopatric (they return to their natal habitat to reproduce), and their upstream movements during the spawning migration are directed by olfactory cues. Two main sources of olfactory cues have been identified—imprinted natal cues and ph...

© 2016 TERRAPUB, Tokyo. All rights reserved. doi:10.5047/absm.2016.00901.0001 pink salmon are phylogenetically the most advanced salmon species, while masu salmon are considered to be the more primitive species (Murata et al. 1996). Pink salmon are also the most widely distributed species and have the largest population size, while masu salmon appear to have the most restricted distribution and...
