Abstract
In Japan chum salmon Oncorhynchus keta is mainly propagated via artificial insemination the release of juveniles from their natal river to the ocean and the recapture of homing adults along the coast and within the natal river The biomass of Japanese chum salmon increased steadily from 1970 to 1996 because of the successful improvement of propagation systems However the returning rate of homing adults has become unstable and the aftermath of the 2011 Tohoku earthquake and tsunami caused a major decrease in the number of juveniles released in the Tohoku area It is now widely accepted that specific factors in the natal stream are imprinted on the nervous system of juvenile chum salmon during downstream migration and that adults use these factors to recognize the natal stream during their upstream homing migration Recent physiological studies from behavioral to molecular biological approaches to elucidate mechanisms of imprinting and homing migration in chum salmon are useful for developing new chum salmon propagation systems to enhance the survival rates of juveniles in coastal areas and stabilize the returning rate of homing adults This review introduces a semiclosed recirculating aquaculture system to estimate the health condition and improve the olfactory imprinting capability of juvenile chum salmonI would like to thank the following collaborative researchers and students in my laboratory for their valuable contributions to the present study Y Naito H Tanaka S Urawa H Kudo H Yamada M Iwata A Urano T Shoji M Shimizu S Yanagi K Sato H Hino Y Yamamoto S Ishizawa H Bandoh S Mizuno N Katayama and N Koide Special thanks are due to the Hokkaido National Fisheries Research Institute and the Hokkaido Salmon Propagation Association for providing valuable data for figures The present study was supported in part by a GrantinAid for Scientific Research from the Ministry of Education Culture Sports Science and Technology MEXT Japan the Japan Society for the Promotion of Science JSPS Japan Science and Technology Agency JST the Hokkaido Foundation for the Promotion of Scientific and Industrial Technology the Mitsubishi Foundation the Mitsui Co Ltd and Hokkaido University
