Environmental influences on thyroid function in teleost fish

Abstract

SYNOPSIS. A brief account of some of the influences that environmental factors, such as the lunar cycle, daylength and temperature, may have on thyroid activity in certain salmonids and the killifish, Fundulus heteroclitus, is presented. The rapid and immediatecharacter of temperature effects is discussed and a role for central neuroendocrine controlin mediating the effects of photoperiod and lunar phenomena involvement is suggested. © 1988 by the American Society of Zoologists.
