Despite many reports of large microplastics being isolated from fish muscle, there are limited exposure studies documenting the transport of microplastics >
10μm from the gastrointestinal tract (GIT) to surrounding tissues. Moreover, egestion rates of microplastics are not commonly studied, especially for carnivorous fish. In this study, experimental data and a literature meta-analysis were combined to understand microplastic translocation to fish tissue and egestion rates. Juvenile barramundi (Lates calcifer) were exposed through their diet to polyamide (PA) fibres and polyethylene terephthalate (PET) fibres and fragments (8-547 μm in length) to determine if shape, size, and polymer type influence microplastic translocation and egestion rates. Despite the high concentration (∼5000 microplastics g
