      of Eastern Oyster (Crassostrea virginica) Larvae.

AB  - Microplastic (MP) pollution is a growing global concern-especially in estuarine 
      areas that serve as natural habitats and nurseries for many marine organisms. One 
      such marine organism is the Eastern oyster (Crassostrea virginica), which is a 
      reef-forming keystone species in the Chesapeake Bay, the largest estuary in the 
      United States. To understand the potential impacts of MP pollution on the estuary 
      ecosystem, the effects of high-density polyethylene (HDPE) MPs on Eastern oyster 
      larval survival and development were investigated. Three cohorts of larvae were 
      exposed to HDPE MPs with a size of 10-90 microm at a 10 mg/L concentration, after 7 
      to 11 days of fertilization. After exposure, the number and size of oyster larvae 
      were measured twice a week for approximately 2 weeks until larval settlement. The 
      experiment found that there were no significant differences in the rate of 
      survival between the control and MP-addition treatments. However, we noticed that 
      larval development was significantly delayed with the MP treatment. The 
      percentage of larvae that were ready to settle was 64% with the control treatment 
      compared to 43.5% with the MP treatment. This delay in growth resulted in a 
      delayed larval settlement, which could adversely affect the survival of the 
      Eastern oyster due to the increased risk of predation. The current study 
      demonstrates that MPs could be a risk to the ecology of estuaries, and plastic 
      pollution management is needed for the preservation of these estuaries.
