Abstract

Bigeye tuna are of global economic importance and are the primary target species of Hawaii's most valuable commercial fishery. Due to their high commercial value, bigeye tuna are relatively well studied and routinely assessed. Larval and adult bigeye surveys have been conducted for many years and are supported by ongoing research on their physiology and life history. Yet, modeling stock dynamics and estimating future catch rates remain challenging. Here, we show that an appropriately lagged measure of phytoplankton size is a robust predictor of catch rates in Hawaii's bigeye tuna fishery with a forecast window of four years. We present a fishery‐independent tool with the potential to improve stock assessments, aid dynamic fisheries management, and allow Hawaii's commercial longline fishing industry to better plan for the future.

  • The 'critical period' hypothesis was also borne out in the study of Woodworth-Jefcoats and Wren (2020).

    “The “critical period” hypothesis was also borne out in the study of Woodworth-Jefcoats and Wren (2020).”

    The Results report significant correlations between phytoplankton size four years earlier and bigeye tuna catch rates in Hawaii’s longline fishery. The Discussion links this finding to the hypothesis that food availability during early life affects survival, but the study did not directly measure survival during that critical period. The finding is consistent with the hypothesis rather than a direct demonstration of it. (LLM, conf=0.83)

  • In Woodworth-Jefcoats and Wren (2020), MD50 was identified as an environmental driver of bigeye tuna recruitment and can be an informative predictor of bigeye tuna catch rates in Hawaii's deep-set longline fishery with a 4-year forecast window.

    “In their study, MD50 was identified as an environmental driver of bigeye tuna recruitment and can be an informative predictor of bigeye tuna catch rates in Hawaii’s deep-set longline fishery with a 4-year forecast window, aligning with the results of our study.”

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.
