Abstract

The seasonal and spatial distributions of larval scombrids in waters off Oahu, Hawaii, were studied in September and December 1985 and April and June 1986 to determine vertical and onshore-offshore patterns.Horizontal distribution was resolved by sampling transects of 3 stations on the windward (east; 3.7, 9.3, and 27.8 km offshore) and leeward (west; 1.8, 9.3, and 27.8 km offshore) sides of the island.Vertical distribution was resolved by sampling with MOCNESS and Manta nets in 8 depth strata (0 to 80 m) at the 2 nearshore stations and 9 depth strata (0 to 200 m) at the 4 offshore stations.Scombrid larvae were abundant in all months except December.Collections in September and June were dominated by Thunnus spp.; about half were large enough to be identified to species and were predominantly T. albacares.Thunnus spp.generally were most abundant closest to shore on the leeward slde of the island.Larval Thunnus were not taken at > 60 m, were most abundant in the upper 20 m, and were captured in the neuston at night but rarely in daytime.The other 2 dominant larval scombrids, Katsuwonus pelamis and Auxis spp.. were most abundant in slightly deeper water.K. pelamis were most abundant at offshore stations, but Auxis spp.showed no clear onshore-offshore pattern.In April, Auxis spp.were most abundant and comprised over 99 "/ o of all larval scombrids.Die1 vertical distribution patterns were not consistent between cruises or sides of the island for any species studied.No evidence was found for die1 migratory behavior.The physical structure of the water column, particularly temperature and salinity, altered the spatial and temporal distribution patterns of larvae on short time and space scales and also on the seasonal scale.Seasonal patterns of spawning were likely dependent upon availability of appropriate thermal habitat.Larval Thunnus spp.and K. pelamis. in particular, were abundant only when temperatures were relatively warm.Auxjs spp.larvae were found over a wider range of temperature than were the other genera.We suggest that the high concentrations of scombrid larvae, particularly Thunnus spp., near islands may be related to habitat characteristics that promote higher larval survival than in oceanic waters.

  • The authors find it unlikely that the vertical distributions of scombrids would simply be a result of passive dispersal due to differences in larval density and movement from physical processes.

    “We find it unlikely that the vertical distributions of scombrids would simply be a result of passive dispersal due to differences in larval density and movement from physical processes (Sclafani et al. 1993;Boehlert and Mundy 1994;Hare et al. 2001).”

    The Discussion says the study found no strong contribution of larval behavior to vertical distribution and instead suggests that larval buoyancy may play an important role. It also describes a change in larval depth distribution as probably related to advective water-mass movement. These passages point toward, rather than rule out, passive and physical processes as explanations. (LLM, conf=0.86)

    Checked by a reasoning model — may be wrong.

  • 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.”

    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.”
  • 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).”

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.
