Effects of microplastic exposure on the body condition and behaviour of planktivorous reef fish (Acanthochromis polyacanthus)

Open access

Abstract

The effect of a pollutant on the base of the food web can have knock-on effects for trophic structure and ecosystem functioning. In this study we assess the effect of microplastic exposure on juveniles of a planktivorous fish (Acanthochromis polyacanthus), a species that is widespread and abundant on Indo-Pacific coral reefs. Under five different plastic concentration treatments, with plastics the same size as the natural food particles (mean 2mm diameter), there was no significant effect of plastic exposure on fish growth, body condition or behaviour. The amount of plastics found in the gastro-intestinal (GI) tract was low, with a range of one to eight particles remaining in the gut of individual fish at the end of a 6-week plastic-exposure period, suggesting that these fish are able to detect and avoid ingesting microplastics in this size range. However, in a second experiment the number of plastics in the GI tract vastly increased when plastic particle size was reduced to approximately one quarter the size of the food particles, with a maximum of 2102 small (< 300μm diameter) particles present in the gut of individual fish after a 1-week plastic exposure period. Under conditions where food was replaced by plastic, there was a negative effect on the growth and body condition of the fish. These results suggest plastics could become more of a problem as they break up into smaller size classes, and that environmental changes that lead to a decrease in plankton concentrations combined with microplastic presence is likely have a greater influence on fish populations than microplastic presence alone.

  • Inclusion of higher order mesopredators (reef fish) in MP studies is less frequent, leaving a gap in understanding of mechanisms of MPs transfer to and ecological fate in higher trophic level organisms.

    “The inclusion of higher order mesopredators (i.e., reef fish) in such studies is less frequent (Critchell and Hoogenboom, 2018; Santana et al., 2021), leaving a gap in our understanding of the mech­ anisms of MPs transfer to and their ecological fate in these higher trophic level organisms.”

    From Trophic transfer of polyester microfibres across a multi-level marine food web. (2025) · cites this paper as Critchell and Hoogenboom, 2018

    The Introduction (page unavailable) says fish-ingestion field studies had primarily focused on pelagic and commercially important species, and that the route by which piscivorous fish acquire microplastics remained unclear. This supports a research gap in trophic transfer, but the paper does not specifically establish that higher-order reef mesopredators are studied less often or describe a gap in the ecological fate of microplastics in those organisms.

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.
