Abstract

El término ‘túnido tropical’ se refiere a un grupo de especies de peces escombriformes que incluye al listado o barrilete (Katsuwonus pelamis), el patudo (Thunnus obesus) y el rabil (Thunnus albacares), que presentan una amplia distribución pantropical, y cuyo óptimo de temperatura superficial del agua del mar en el que habitan se sitúa en torno a los 20°C. Actualmente, dos de estas especies se encuentran entre las 7 especies con mayores volúmenes de desembarque a nivel mundial. Se prevé que en el futuro los stocks de túnidos tropicales jueguen un papel fundamental para salvaguardar la seguridad alimentaria. El objetivo de este trabajo fue presentar los principales retos de la biología pesquera en relación a la gestión de las poblaciones de túnidos tropicales en un contexto de cambio climático. Para esto se revisaron los estudios que se han abordado hasta el presente sobre el efecto tanto de las oscilaciones climáticas, como del calentamiento global en las poblaciones de túnidos tropicales.

TL;DR

This review synthesizes evidence that climate oscillations and global warming affect tropical tuna abundance, reproduction, recruitment, catchability, and distribution, with model projections generally showing a 2100 biomass increase in the Eastern Pacific and decreases in the Central/Western Pacific. It argues that tropical tunas are central to future food security under population growth and climate change, while highlighting major uncertainties and a strong Pacific research bias.

Key findings

  • Tropical tunas—skipjack, bigeye, and yellowfin—inhabit waters with an optimal sea surface temperature around 20°C; skipjack and yellowfin are among the 7 marine species with the highest landings worldwide, and skipjack fishing mortality is considered below the level that would provide maximum sustainable yield at equilibrium.
  • Climate oscillations can affect tropical tuna abundance, reproductive condition, recruitment, and catchability; El Niño can deepen the thermocline and put bigeye schools out of purse-seine reach, and an analogous North Atlantic Oscillation effect has been observed for yellowfin catches in the eastern Atlantic.
  • Climate models project for the next 100 years a sea surface temperature increase of 3°C, a pH decrease of 0.3 units, oxygen concentrations below the mixed layer below 30 mmol kg−1, and decreased salinity/stratification; some models project reduced large pelagic fish and tuna biomass by the end of the century, and for 2100 generally a significant tropical tuna biomass increase in the Eastern Pacific versus a decrease in the Central and Western Pacific.
  • Food-security context: the UN reported 7.3 billion people in 2015 and projects 9.7 billion by 2050; tropical tunas are considered essential for global food security, yet canned tuna uses only 32–40% of raw material, dark meat (10–13%) is used for pet food, and almost 50% remains as viscera, spines, bones, and scales; in Abidjan, faux poisson landings were estimated at 21,582 t, corresponding to half of the captured amount that could be usable.

Methods

  • Review/overview of studies addressing the effect of climatic oscillations and global warming on tropical tuna populations; no new empirical data are presented.
  • Bibliographic search in Scopus®, Web of Science, Google Scholar, and RFMO reports using keywords including “Tuna+Climate change projection,” “tuna modeling+projection,” and “forecasts+tuna population trends”; the paper reports finding 16 studies in Table 1, mostly focused on the Pacific (11 studies plus 2 pantropical).
  • Narrative synthesis of climate-projection results, stock-assessment context, and management/food-security implications.

Limitations

  • Stated: projections have important uncertainties inherent to different climate change scenarios; most studies focus on the Pacific, with a notable deficit of information for other oceans; short-term population-dynamics models validated with empirical observations are needed.
  • Evident: as a review, it does not present original quantitative analysis, and its synthesis is constrained by the small number of projection studies found and their geographic concentration.

    Currently most studies are focused on the Pacific Ocean, so there is a very notable deficit of information on the potential effects of climate change in other oceans.

    These predicted ocean changes would probably have an immediate effect on primary production, with cascading effects along the trophic chain.

    Assuming the effects of global warming are inevitable in the short and medium term, and foreseeing that demand for marine meat including tunas will increase by 2030 due to world population increase, added to the probably negative effect of global climate change in coming decades, could trigger a collapse of commercial tuna stocks in the long term.

    “Asumiendo que son inevitables los efectos del calentamiento global a corto y medio plazo, y previendo que se incrementará la demanda del consumo de carne de especies marinas hacia el 2030, entre ellas los túnidos, debido al incremento de la población mundial, lo cual sumado al efecto, probablemente negativo que tendrá el cambio climático a nivel global, en las próximas décadas, podría desencadenar”

    Mediterranean waters are poco productivas, so they could not sustain large abundances of emigrant tunas in addition to existing populations.

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.

A language model drew the claims from the paper on 2026-10-16, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-16 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Cited sources are checked with a language model’s help (gpt-6-sol).

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.
