  • The conjecture that the boundaries of tuna spawning grounds are located between the 24°C isotherms may need to be revisited.

  • Tuna larvae occur within the adults' distributional range, but are restricted to lower latitudes and higher water temperatures than adults.

    “Our results showed that tuna larvae occur within the adults' distributional range, but were restricted to lower latitudes and higher water temperatures than adults, largely consistent with Schaefer's 'temperature hypothesis'.”
  • There is very limited scientific information on the spatio-temporal spawning patterns of tuna species and strong uncertainties in knowledge of many biological parameters, including reproduction, of tuna species.

    “There is very limited scientific information on the spatio-temporal spawning patterns of tuna species (Schaefer 2001) and strong uncertainties in our knowledge of many biological parameters, including reproduction, of tuna species.”
  • Schaefer (2001) hypothesized that tuna spawning is constrained by larval development, which is very short compared with temperate species.

  • In the Pacific Ocean, mean spawning interval has been determined as 1.18, 1.53 and 1.09 days for skipjack, yellowfin and bigeye tuna respectively.

    “in the Pacific Ocean the mean spawning interval has been determined as 1.18 , 1.53 and 1.09 days for skipjack, yellowfin and bigeye tuna respectively (Schaefer, 2001).”

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.
