“…This phenomenon, greater metabolic depression for the same value of temperature change at a lower temperature, has also been found in other Sparid species. For example, in Lithognathus mormyrus the Q 10 change is higher between 15 • C and 10 • C than it is between 20 • C and 15 • C (Du Preez et al 1986). Fry and Hochachka (1970) and Hochachka and Somero (1971) demonstrated that fish may adjust their metabolisms in order to compensate for the effects of temperature changes.…”

Low temperature has been implicated in inducing outbreaks of 'winter syndrome' or 'winter disease' in farmed gilthead sea bream (Sparus aurata). The responses of gilthead sea bream to reduced temperature followed by maintenance at low temperature were studied. In a first experiment, oxygen consumption was measured when water temperature was reduced from 18 • C to 8 • C at either a rate of 1 • C · day −1 or as two 'sharp drops' (from 18 • C to 12 • C, and from 12 • C to 8 • C). In a second experiment, the water temperature was reduced from 16 • C to 8 • C or 12 • C and then maintained for 20 days to study the fish acclimation to these temperatures. In both experiments, fish stopped feeding below 13 • C and did not resume feeding when maintained at low temperatures. The decrease in metabolic activity, expressed by the oxygen consumption rate, was directly related to the fall in water temperature: the Q 10(18 • C−8 • C) values were between 2.2-2.5, independently of the descend rate in water temperature. However, we observed a more reduced metabolic rate when the water temperature was below 12 • C. Fish maintained at low temperatures showed only a partial recovery in oxygen consumption (15% at 8 • C and 20% at 12 • C) after 20 days. A higher metabolic rate together with a fasting-temperature condition meant that maintenance at 12 • C was more aggressive than at 8 • C, as revealed by the condition factor and energy needs. Data suggest that 12 • C could be a threshold temperature for the metabolic activity of gilthead sea bream. The relationship between low temperatures and their possible implication in the appearance of 'winter disease' in gilthead sea bream is also discussed.

“…The data collected on the first day the fish were placed in the chambers were not used because of the known effect that handling has on fish physiology (Saunders, 1963). This was a conservative precaution; other studies have shown that oxygen consumption rates stabilized after a few hours of handling (Smith, 1978;Smith and Laver, 1981;Smith and Brown, 1983;Du Preez et al, 1986). The decrease in oxygen used on the first day of an experiment can be seen in Figure 5.1.…”

“…Handling can increase 0 2 consumption by 70% and have noticeable effects for 3-5 h afterwards (Saunders, 1963). Other authors have also noted that handling affects the fish for 20 min to hours after capture (Smith, 1978;Smith and Laver, 1981;Smith and Brown, 1983;Du Preez et al, 1986). Oxygen consumption of fishes rises after feeding.…”

“…When the light-dark cycle was shifted, so did these behaviors, indicating that the light cycle was the synchronizer. The oxygen consumption rates of Lithognathus mormyrus and L. lithognathus also show a diel pattern (Du Preez et al, 1986). Smith and Laver (1981) suggested that a diel rhythm occurred in the bathypelagic fish Cyclothone acclinidens; respiration rates at night were 3-5 x higher than during the day.…”

“…Therefore, fed fishes can have artificially high standard metabolic rates. Du Preez et al (1986) noted that SMR in fed sparids were 44% higher than those starved, and Sullivan and Smith (1982) noted that starved fish had a low oxygen consumption rate.…”

SynopsisThis paper reviews investigations on the ecophysiology of a population of roach, Rutilus rutifus, from a subalpine oligotrophic lake in the Austrian Tirol. Metabolic responses to season and temperature were studied in whole animals, tissues and selected enzymes. The exponent of the relationship between body mass and three levels of the metabolic rate of acclimated fish was 0.82 + 0.02,0.60 f 0.15, and 0.75 f 0.01 at 4, 12, and 20" C respectively. Various combinations of long-term acclimation to constant or seasonally fluctuating temperatures and long-term (up to 14 days) monitoring of VO, at the acclimation temperature led to the conclusion that the aerobic power of fish swimming in the routine mode does not show any sign of being temperature compensated. On the other hand, there are several indications that the energy expenditure of spontaneously swimming fish is adjusted to the seasonal pattern of environmental change and that these responses of metabolism and behaviour are controlled by both endogenous and exogenous factors. The rate of oxygen consumption of gill and muscle tissue 'brei' from fish caught during a seasonal cycle and measured at 15" C appears to follow closely the reproductive and gonadal cycle of the living fish. The same holds for the activities of phosphofructokinase, acetoacetyl-CoA thiolase, and cytochrome oxidase. On the other hand, the Na+, K+-ATPase of the kidney shows near perfect temperature compensation when fish acclimated to 5 and 25" C are compared, whereas an equally pronounced case of inverse temperature acclimation has been reported for the activity of digestive enzymes in the gut. Summarizing these data it is pointed out that the temperature relationship of a poikilothermic organism is the sum of often very diverse temperature relationships of specific metabolic and behavioural functions. In the case of the roach, strong effects of acclimation temperature on the molecular level, sometimes in the opposite direction, combine with seasonal effects on enzyme activities and tissue respiration. However, on the whole animal level the fish behave as strictly non-compensating poikilotherms, the reproductive cycle being the only detectable influence capable of modulating the basic temperature relationship of energy expenditure.Introduction two phases and is now in a third phase. In the first phase poikilothermic animals were regarded as beAs pointed out in a review some time ago (Wieser ing at the mercy of the thermal environment, an 1973)) the interpretation of temperature relations interpretation best expressed by Krogh's so-called of poikilothermic animals has already run through 'normal curve' (Krogh 1914). In the second phase,
