“…The near doubling of the O 2 consumption during the SDA at 24 h fits well with the normal results in most water-breathing animals (21,22,25). This study showed that postprandial O 2 consumption was abruptly reduced by exposing animals to water at a PO 2 of 3 kPa (arterial PO 2 ϭ 0.5-0.6 kPa) but not to water PO 2 of 4 kPa (arterial PO 2 of 0.6-0.8 kPa).…”

. Influence of oxygen partial pressures on protein synthesis in feeding crabs. Am J Physiol Regul Integr Comp Physiol 284: R500-R510, 2003; 10.1152/ ajpregu.00193.2002.-Many water-breathing animals have a strategy that consists of maintaining low blood PO 2 values in a large range of water oxygenation level (4-40 kPa). This study examines the postprandial changes in O 2 consumption, arterial blood PO2, and tissue protein synthesis in the shore crab Carcinus maenas in normoxic, O2-depleted, and O2-enriched waters to study the effects of this strategy on the O2 consumption and peptide bond formation after feeding. In normoxic water (21 kPa), the arterial PO2 was 1.1 kPa before feeding and 1.2 kPa 24 h later. In water with a PO2 of 3 kPa (arterial PO2 0.6 kPa), postprandial stimulation of protein synthesis and O2 consumption were blocked. The blockade was partial at a water PO2 of 4 kPa (arterial PO2 0.8 kPa). An increase in environmental PO2 (60 kPa, arterial PO2 10 kPa) resulted in an increase in protein synthesis compared with normoxic rates. It is concluded that the arterial PO2 spontaneously set in normoxic Carcinus limits the rates of protein synthesis. The rationale for such a strategy is discussed. crustaceans; oxygen consumption; blood oxygen; hypoxia IN AIR-BREATHING HOMEOTHERMS the PO 2 in the arterial blood is regulated at 10-14 kPa in resting conditions at sea level (Ref. 6; for reference, PO 2 in air at sea level is 20-21 kPa). At the cellular level the most frequently measured values are in the 1-to 3-kPa range in the tissues (43). In numerous water breathers and other poikilotherms, the arterial PO 2 is also set at 1-3 kPa (reviewed in Ref. 27). It has been suggested that these low PO 2 values are part of a strategy of cell oxygenation termed "the low tissue O 2 strategy," which evolved with the origin of aerobic metabolism (27).In water-breathing animals, there is a strategy of gas-exchange regulation that consists of maintaining PO 2 in the arterial blood in an astonishingly low and narrow range, about 5-10 times lower than in homeotherms. Previous studies in crustaceans reported that O 2 , working in the low PO 2 range, acts 1) in a neuromodulator-like manner on the neural networks that generate the masticating and filtering movements of the foregut (5, 31) and 2) limits the oxidative metabolism of locomotor muscles (12).This paper aims to determine whether the low tissue O 2 strategy could affect protein metabolism in a water breather. Around 60 O 2 -dependent reactions exhibit values of the Michaelis-Menten constant for O 2 (K m,O 2 ) that would be rate limited at likely tissue O 2 levels (except for cytochrome-c oxidase; Ref. 43). Besides these reactions there may also be a limitation on the rate of energy supply for other processes. If these conditions are present in vivo in water breathers, we would expect that 1) an increase in tissue energy demand would result in an increase in blood PO 2 to drive an increase in tissue oxygenation and/or an increase in blood flow; 2) a reduction in envir...

“…4). In general, feeding increases the oxygen consumption in organisms; which is associated with numerous mechanical and biochemical processes related with food ingestion, digestion absorption and assimilation as well as, protein synthesis and deposition (Fu et al, 2006;Jobling, 1981). Jobling (1994) suggested that the maximum rate of oxygen consumption induced by feeding appears to be approximately double of fasted metabolism.…”

Senegalese sole is known to be a species with pronounced nocturnal feeding behaviour. However, as for most fish species, there is a lack of knowledge concerning the influence of such biological rhythm on metabolic rate. The aim of this study was to determine whether individual variation in routine and fed metabolic rate was affected by daily light-dark rhythms in juveniles of Senegalese sole. The individual oxygen consumption measurements in Senegalese sole juveniles were determined by flow-through respirometry, at fasted conditions and after the fish were fed a single meal, the meal time started at 0930 h and fish fed ad libitum for 30 min. The measurements were made during 22 h, of which 8 h was in the light and 14 h in the dark, and started immediately after transfer to the respiratory chambers at 1100 h. The results suggest an influence of light-dark cycles in routine metabolism. It was observed that oxygen consumption increased during the dark phase in fasted fish (FAST) but was higher during the light phase in fed fish (FEED). However, when feed is provided during the light phase, juveniles are capable of shifting oxygen consumption rhythms to respond to the energetic demands of digestion and growth. These results suggest that routine metabolism varies according to the species natural habits as Senegalese sole is known to be nocturnal. The findings of this study underline the importance of understanding the biological rhythms of the species under study before metabolic data are interpreted.

“…There is increasing evidence that, at least in discontinuous feeders, growth tends to occur in a pulse immediately following a meal. The respiratory cost of growth may thus explain much of the post-prandial increase in oxygen consumption (the specific dynamic action, SDA : Jobling 1981: Jobling ,1983, and perhaps nitrogen excretion (Bayne & Scullard 1977). In the starfish Asterias rubens, for example, there is a strong correlation between the extent of SDA and overall growth rate (Vahl 1984).…”

The traditional IBP formulation of the energy budget is unsuitable for many marine organisms, partly because it sets production and respiration as alternative sinks when in reallty they are linked but also because it fails to recognise the heterogeneous nature of respiratory demand. The vanous components of total respiration reflect separate demands for ATP which are hkely to differ in their response to temperature and season. Such subdivision of total respiration emphasizes the difference between reproductive effort (RE, that fraction of the total energy flux diverted to reproduction) and reproductive output (RO, weight-specific gonad production) as measures of reproductive energehcs. Model calculahons demonstrate that the variation of basal metabolic rate with temperature (and hence latitude) influences both RE and RO, but in differing ways. If annual RE is assumed to be roughly constant in tropical, temperate and polar populations, then for organisms of similar size and ecology annual R0 will decrease with increasing latitude. Conversely if R 0 remains constant then annual RE will increase at high latitudes. Similar arguments predict an increase in net growth efficiency at low temperatures. When Lifetime RE is considered in relation to the slower growth rates and increased age of first breeding frequent at high latitudes, then data for the caridean shrimp Pandalus borealis suggest the possibility that there is a balance between basal metabolism and growth rate, resulting in a relatively constant lifetime RE across the latitudinal range. Clearly rather than there being a simple competition between growth and reproduction, energy is divided between several competing sinks which include the costs of maintenance and activity.
