This study addressed three questions concerning interactions between physiology and dominance in juvenile rainbow trout: (1) the validity of a model predicting a time-dependent effect of fasting on competitive ability (i.e., the ability to obtain contested food items) was tested in a series of dominance trials between fed and progressively more fasted trout, as was (2) the association between fasting and plasma growth hormone levels. (3) The relationship between plasma growth hormone levels and the competitive ability of individual trout was also studied. The main results were as follows: (1) The predictions of the time-dependent model were supported by the fasting-dominance experiment. After 3 days, fasted fish were dominant over fed fish, whereas after 6 and 9 days, the competitive ability of fed and fasted fish was similar. After 12 days, there was a tendency for fed fish to be dominant over their fasted competitors. (2) Sampling of plasma from fed and fasted trout, after 3, 6, 9, and 12 days, demonstrated that plasma growth hormone levels increases in food-deprived rainbow trout after more than 6 days of fasting, which is consistent with previous work. (3) No difference in plasma growth hormone levels was found between paired dominant and subordinate trout. Possible interactions between nutritional state, growth hormone levels, and dominance, and their implications are discussed.
