Kernel density estimation of potential microplastic size distribution based on 40 out of 58 particles extracted with NaCl density separation from whitefish fishmeal (n = 6). 87.2% were microparticles ≤ 1000 µm and 12.8% microparticles 1000–5000 µm. Note: the single > 5000 µm particle (6436 µm) is excluded from microplastic calculations.
