Effects of microplastic exposure on the body condition and behaviour of
\nplanktivorous reef fish (Acanthochromis polyacanthus)<\/p>\n

PLoS ONE 13(3): e0193308.<\/p>\n

Abstract<\/p>\n

The effect of a pollutant on the base of the food web can have knock-on
\neffects for trophic structure and ecosystem functioning. In this study
\nwe assess the effect of microplastic exposure on juveniles of a
\nplanktivorous fish (Acanthochromis polyacanthus), a species that is
\nwidespread and abundant on Indo-Pacific coral reefs. Under five
\ndifferent plastic concentration treatments, with plastics the same size
\nas the natural food particles (mean 2mm diameter), there was no
\nsignificant effect of plastic exposure on fish growth, body condition or
\nbehaviour. The amount of plastics found in the gastro-intestinal (GI)
\ntract was low, with a range of one to eight particles remaining in the
\ngut of individual fish at the end of a 6-week plastic-exposure period,
\nsuggesting that these fish are able to detect and avoid ingesting
\nmicroplastics in this size range. However, in a second experiment the
\nnumber of plastics in the GI tract vastly increased when plastic
\nparticle size was reduced to approximately one quarter the size of the
\nfood particles, with a maximum of 2102 small (< 300\u03bcm diameter)
\nparticles present in the gut of individual fish after a 1-week plastic
\nexposure period. Under conditions where food was replaced by plastic,
\nthere was a negative effect on the growth and body condition of the
\nfish. These results suggest plastics could become more of a problem as
\nthey break up into smaller size classes, and that environmental changes
\nthat lead to a decrease in plankton concentrations combined with
\nmicroplastic presence is likely have a greater influence on fish
\npopulations than microplastic presence alone.<\/p>\n
