Abstract

Vertical distributions of larvae of 3 tuna species were investigated in the East Indian Ocean.In the presence of a strong pycnocline, the entire depth range of tuna larvae could be covered by sampling the mixed layer by both day and night.A small proportion of tuna larvae were found below the mixed layer when the pycnocline was weak.Thunnus maccoyii and T. alalunga larvae moved into the surface layers durlng the day.Katsuwonuspelamis, however, moved into deeper water during the day.All species of tuna were more evenly dispersed in the mixed layer at night.Greater numbers and larger larvae of T rnaccoyli and K pelanijs were captured at night, indicating marked differences in net avoidance between day and night.No evldence of increased avoidance during the day was found in T alalunga.The relative abundance of T m a c c o j ~~i larvae could be predicted from surface tows; however, the relationship between surface and obllque tows showed regional and diel variability.To reduce blas and increase preclslon, estimates of tuna larvae abundance should be based on oblique tows made at night from the surface to just below the mixed layer.

  • Some scombrid species have shown significantly different vertical distributions in response to highly selective predation.

    “Some scombrid species have shown significantly different vertical distributions in response to highly selective predation (Davis et al. 1990;Llopiz et al. 2010), and similar processes could be affecting the vertical distributions in the Gulf of Mexico.”

    From A comparison of sampling methods for larvae of medium and large epipelagic fish species during spring SEAMAP ichthyoplankton surveys in the Gulf of Mexico (2014) · cites this paper as Davis et al. 1990

    The Abstract and Diel vertical distribution section report different daytime depth patterns among the three tuna species. The paper does not establish that these differences are a response to highly selective predation; it discusses feeding as a possible explanation and mentions predator avoidance only as a general hypothesis in the Introduction. No page numbers are available in our copy. (LLM, conf=0.87)

  • The differences in vertical distribution may be a result of a shallower thermocline, halocline, or pycnocline as would be seen in divergences associated with boundaries of anti-cyclonic eddies and the Loop Current frontal zone.

    “These differences may be a result of a shallower thermocline, halocline, or pycnocline (Davis et al. 1990;Hare et al. 2001) as would be seen in divergences associated with boundaries of anti-cyclonic eddies and the loop current frontal zone.”

    The Depth distribution section says a well-defined pycnocline appears to restrict tuna larvae to the mixed layer, supporting the proposed link between a shallow water-column boundary and vertical distribution. The paper does not establish a separate effect of a halocline, and its East Indian Ocean findings do not address the Loop Current or anticyclonic-eddy boundaries mentioned in the citing sentence. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Many of the targeted pelagic taxa have shown vertical and horizontal distributions that would suggest direct or indirect competition with bluefin tuna larvae.

    “Many of these taxa have shown vertical and horizontal distributions (Davis et al. 1990;Boehlert and Mundy 1994;Hare et al. 2001;Prince et al. 2005;Richardson et al. 2009;Muhling et al. 2010;Lindo-Atichati et al. 2012;Rooker et al. 2012) that would suggest direct or indirect competition with bluefin tuna larvae.”

    The Abstract and Diel vertical distribution section report the depth distributions of southern bluefin and other tuna larvae, including similar vertical dispersal at night. The cited paper does not establish horizontal overlap or suggest direct or indirect competition with bluefin tuna larvae; it notes differences in daytime depth and diet. Page numbers are not available in our copy. (LLM, conf=0.84)

  • Scombrid larvae exhibited different vertical distributions by species.

    “Scombrid larvae exhibited different vertical distributions by species as has been described in previous studies (Davis et al. 1990;Boehlert and Mundy 1994;Hare et al. 2001).”
  • Earlier studies (Davis et al. 1990; Boehlert and Mundy 1994) examined vertical distributions over sampling intervals larger than 10 m and may have missed discrete differences in abundance between the surface and 50 m.

    “The earlier studies (Davis et al. 1990;Boehlert and Mundy 1994), however, examined vertical distributions over sampling intervals larger than 10 m, and may have missed discrete differences in abundance between the surface and 50 m.”

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.
