Several species of fish swim upstream into the area of greatest turbulence in artificially created currents of water. This reaction is most pronounced with young salmon and trout.
Treatment with thyroxine, testosterone and three oestrogen compounds slightly increases the rate at which coho and sockeye salmon smolt jump upstream over a dam.
Elevated temperatures increase the amount of negative rheotaxis shown by chum fry and coho smolt in circular currents. / Science, Faculty of / Zoology, Department of / Graduate
