Growth-dependent recruitment of Pacific bluefin tuna Thunnus orientalis in the northwestern Pacific Ocean
Open accessAbstract
To estimate the survival process of Pacific bluefin tuna Thunnus orientalis during the larval period, estimated growth histories were compared between larvae collected in late spring and juveniles collected in the boreal summer of 2004, which were considered to be survivors of the larval cohorts.Larval tuna (3.3 to 9.6 mm standard length, SL) were collected from mid-May to early June around the Ryukyu Islands, northwestern Pacific Ocean, and juvenile tuna were collected offshore of Kochi and Nagasaki prefectures in July-August.Preflexion, flexion and postflexion larvae were collected, and their ages ranged from 4 to 18 d.Back-calculated SLs by the biological intercept method showed that larval tuna in the postflexion phase were larger-at-age than preflexion and flexion larvae, suggesting that only larger and faster growing larvae were able to survive to the postflexion phase.The logarithms of otolith radii (ln OR: proportional to SL) of larvae with slower growth and development were smaller than the minimum ln OR of surviving juvenile tuna, which indicated the smallest possible size required for larvae to successfully recruit to the fishery.These results indicate that the survival of larvae of Pacific bluefin tuna depends largely on size and growth rates during early life history.

Larval collections in both the Atlantic and Pacific oceans have mostly been restricted to waters between ~22 and 28°C.
“Larval collections in both the Atlantic and Pacific oceans have mostly been restricted to waters between ~22 and 28°C (Masuma et al. 2006, Tanaka et al. 2006, Alemany et al. 2010, Muhling et al. 2010).”
From Comparison between environmental characteristics of larval bluefin tuna Thunnus thynnus habitat in the Gulf of Mexico and western Mediterranean Sea (2013) · cites this paper as Tanaka et al. 2006
The Materials and Methods section describes larval collections in the northwestern Pacific, and the Developmental phases and standard length section reports station temperatures of 25.0–28.8°C. This supports collections in warm Pacific waters, but the paper does not address Atlantic collections or establish a general 22–28°C range for both oceans. (LLM, conf=0.88)
Experimental — accuracy not yet measuredFew studies exist on the effects of temperature on larval tuna growth, with some studies finding no association and others a positive association.
“Few studies exist on the effects of temperature on larval tuna growth, with some studies finding no association (Jenkins et al. 1991, Tanaka et al. 2006) and others a positive association (Reglero et al. 2011, Garcia et al. 2013).”
From Comparison between environmental characteristics of larval bluefin tuna Thunnus thynnus habitat in the Gulf of Mexico and western Mediterranean Sea (2013) · cites this paper as Tanaka et al. 2006
The Larval growth history and growth rate section says growth histories were not found to be affected by mean water temperature at sampling stations, supporting Tanaka et al. as an example of a study finding no general association. But it also reports a significant difference at Day 7, and the Growth of larval bluefin tuna in the field section cautions that station temperatures may not reflect the temperatures larvae experienced. An unqualified finding of no association between experienced temperature and growth therefore overstates the study. (LLM, conf=0.85)

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.
