Effect of Temperature on the Rate of Gastric Digestion in Finger ling Sockeye Salmon, Oncorhynchus nerka
Abstract
By means of serial slaughter the rate of gastric digestion in yearling sockeye salmon (30–40 g) was studied at approximately 3, 5, 10, 15, 20, and 23 C, after satiation feeding on Abernathy pellets. Subsequently the ash-free dry weight of the stomach contents was determined and expressed as a fraction of the dry weight of the fish. At any one temperature, rate of digestion appeared to be proportional to the mass of food remaining in the stomach (exponential decline). The time for complete digestion decreased from 147 hr at 3 C to 18 hr at 23 C. The time for one-half of a sample of fish to exhibit empty stomachs corresponded closely to that for a mean state of 96% gastric digestion, providing a simple means for determining rate of digestion.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
