AB  - Understanding the effects of plastic debris on marine ecosystems is essential in 
      encouraging decision-makers to take action. The present study investigates the 
      effect of a 24 h experimental exposure to high density polyethylene (HDPE) 
      microplastics (MPs) of different sizes (4-6, 11-13 and 20-25 mum) and at three 
      concentrations (0.1, 1 and 10 mg MP.L(-1)) on the development and locomotor 
      activity of early stages of Pacific oyster, Crassostrea gigas. The bivalve 
      embryo-larval assay (NF ISO 17244, 2015) was used in this study but with 
      additional toxicity criteria: developmental arrests, abnormal D-larvae, maximum 
      speed and swimming trajectory. Copper (Cu), was used as a positive control. Our 
      results show that smaller MPs (4-6 and 11-13 mum) induced higher rates of 
      malformations and developmental arrests than the larger ones (20-25 mum). In 
      addition, a dose-dependent decrease of maximum swimming speed was observed for 
      larvae exposed to MPs of 4-6 and 11-13 mum. On the other hand, there was no 
      significant difference in swimming speed with the largest MPs size tested 
      (20-25 mum). For all three sizes of MPs, there was a decrease in straight-line 
      swimming trajectories, and an increase in circular trajectories. This abnormal 
      swimming behaviour could affect larvae survival as well as colonization of new 
      habitats.
