Oxy-calorific coefficients for animals respiring nitrogenous substrates

Heat Increment Associated with Dietary Protein, Fat, Carbohydrate and Complete Diets in Salmonids Comparative Energetic Efficiency

“…Protein has a lower HI when used for tissue synthesis than when used to supply energy in mammals. Furthermore, the factor for converting oxygen consump tion to heat production is not constant but depends upon the material being oxidized and on the nature of the waste products being excreted (21).…”

How zebrafish turn: analysis of pressure force dynamics and mechanical work

“…Consequently, the net metabolic rate related to movement is described by 3.2×A. For a turning activity level of A=10, which we estimated to be similar to our experiments, we computed a net metabolic rate of 121 mJ kg −1 s −1 using the oxy-calorific equivalent of 13.60 J mg −1 O 2 (Brafield and Solomon, 1972). Plaut and Gordon (1994) measured oxygen consumption in swimming zebrafish at different controlled speeds and a water temperature of 28.0±0.2°C.…”

Inherent instability leads to high costs of hovering in near-neutrally buoyant fishes

“…To account for differences in size, salinity, and temperature across the species, the ratio MO 2hover /MO 2rest was calculated to measure the relative energy expenditure for hovering compared to resting ( 56 ). The net energy required to hover for 10 min was then converted to KJ kg −1 using an oxy-calorific equivalent of 3.25 cal per 1 mg O 2 ( 60 ). The species were classified into two groups based on their metabolic rates (MO 2net and MO 2hover /MO 2rest ).…”
