“…It is likely that the abalone are compensating for the lower enzyme activity by reducing food intake and possibly retaining feed in the body for longer, as observed in this study. Increasing meal size, or increasing the amount of meals an animal ingests daily, has been demonstrated to increase GIE times in other poikilothermic animals (Flowerdew and Grove, 1979;Lee et al, 2000;McGaw and Curtis, 2013;Riche et al, 2004), however, in the present study, increasing feed intake that occurred with increasing temperatures had no significant effect on the duration on faecal excretion. Hence, these animals appear to adapt to lower enzymatic activity by consuming less food, commencing their faecal excretion later and completing their voiding of faeces later, resulting in no change to GIE duration.…”

“…Although the factorial scope may be similar across all body sizes in some species (e.g., McGaw & Curtis, ), in most species the factorial scope increases with body size (e.g., Boyce & Clarke, ). The effects of meal type and size have been studied in several marine invertebrates (e.g., McGaw & Curtis, ; Rosas et al., ). Typically, an animal's factorial scope and duration increase with increased meal sizes and with meal types that are costlier to digest.…”

“…In animals that obtain their energy primarily through the oxidation of ingested food, the amount of oxygen they consume can serve as a measure of energy metabolism (Schmidt-Nielsen 1996). The oxygen consumed is used in the maintenance of physiological functions such as locomotion, feeding, digestion, and food absorption as well as in the synthesis of new tissues (Diaz-Iglesias 2012;McGaw & Curtis 2013). Ammonia is the main nitrogen compound excreted by aquatic animals.…”
