Abstract

The distribution pattern of albacore, Thunnus alalunga, in the Indian Ocean was analyzed based on catch data from the Taiwanese tuna longline fishery during the period 1979–85. The Taiwanese tuna fishery began operating in the Indian Ocean in 1967. We used a geographic information system to compile a fishery and environmental database and statistically explored the catch per unit effort (CPUE) distribution of albacore. Our results indicated that immature albacore were mainly distributed in areas south of 30°S although some displayed a north–south seasonal migration. Mature albacore, which were mainly concentrated between 10°S and 25°S, also showed a north–south migration. Within 10°S and 30°S, the separation of mature, spawning, and immature albacore life history stages roughly coincided with the boundaries of the three oceanic current systems in the Indian Ocean. The optimal environmental variables for CPUE prediction by stepwise discriminant analysis differed among life history stages. For immature albacore, the sea surface variables sea surface temperature (SST), chlorophyll concentration and surface salinity were significant. For mature albacore, SST was significant, while for spawning albacore, the sub‐surface variables temperature at 100 m and oxygen at 200 m were significant. Spawning albacore evidently prefer deep oceanographic conditions. Our results on the oceanographic conditions preferred by different developmental stages of albacore in the Indian Ocean were compatible with previous studies found in the Pacific Ocean.

  • Habitat studies using fishery or survey data are often spatially limited and focused on single species.

    “Habitat studies using fishery or survey data are often spatially limited and focused on single species (e.g.Chen et al., 2005;Sagarminaga and Arrizabalaga, 2010).”

    From Global habitat preferences of commercially valuable tuna (2015) · cites this paper as Chen et al., 2005

    The Introduction describes limitations in the spatial coverage of past fishery-oceanography studies, and this paper’s own habitat analysis focuses on one species, albacore. But it uses fishery and environmental data across the whole Indian Ocean, so Chen et al. is not itself an example of a spatially limited study. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • The distribution of albacore is affected by SST.

    “Previous studies have shown that the distribution of albacore is affected by SST (Chen et al. 2005).”

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.
