Sculpin in the mysid group took in 8 to 11
times more microplastics by number and 3 to 5 times more by mass than those in
the water group. The microplastics were finely granulated during the process of
uptake by mysids, and as a result, the microplastics taken up by sculpins in
the mysid group were smaller in particle size than those in the water group.
This indicates that the indirect pathway via prey organisms is more important
than the direct pathway from the water for the uptake of microplastics by fish.
