متن کاملSwimming speeds and buoyancy compensation of migrating adult chum salmon Oncorhynchus keta revealed by speed/depth/acceleration data logger.
Although the homing migration of Pacific salmon is well documented, the swimming behaviour of the returning salmon has been poorly described, principally as a result of the difficulties encountered in monitoring salmon behaviour in the sea. The present study describes the use of a recently developed electronic data logger to obtain simultaneous recordings of the swimming speed, depth, fin-beati...
متن کاملThe Olfactory Transcriptome and Progression of Sexual Maturation in Homing Chum Salmon Oncorhynchus keta
Reproductive homing migration of salmonids requires accurate interaction between the reception of external olfactory cues for navigation to the spawning grounds and the regulation of sexual maturation processes. This study aimed at providing insights into the hypothesized functional link between olfactory sensing of the spawning ground and final sexual maturation. We have therefore assessed the...
متن کاملfrom Chum Salmon
Cystatin, a cysteine proteinase inhibitor, was isolated from chum salmon (Oncorilynch"s keta) pituitary glands by ion-exchange chromatography on Mono-Q, gel filtration on Superdex 75, and reverse-phase HPLC on an ODS fo1]owing ethanol-ammonium acetate extraction. Salmon pituitary cystatin was equipotent te chicken egg-white cystatin in the papain inhibitory assay. The cystatin consists of 111 a...
متن کاملInvolvement of hormones in olfactory imprinting and homing in chum salmon.
The olfactory hypothesis for salmon imprinting and homing to their natal stream is well known, but the endocrine hormonal control mechanisms of olfactory memory formation in juveniles and retrieval in adults remain unclear. In brains of hatchery-reared underyearling juvenile chum salmon (Oncorhynchus keta), thyrotropin-releasing hormone gene expression increased immediately after release from a...
