Microplastics in Shellfish Aquaculture

NIC is testing the polymer degradation of anti-predator netting used in shellfish aquaculture around the Comox Valley on Vancouver Island. A methodology is being developed to evaluate the different ages of netting and to determine which additives and/or microplastics from the netting leach into the water during their lifespan.

Project Summary

This project is focused on the degradation of polymer anti-predator netting used in shellfish aquaculture around Vancouver Island. Two experiments have been proposed to evaluate the various types and concentrations of microplastics and/or additives leaching into the ocean from anti-predator netting. In the first experiment, anti-predator netting of different ages will be tested and evaluated for the degradation of its mechanical properties. In the second experiment, used and new anti-predator netting will be tested to determine the levels of leaching of certain additives often used in UV-resistant coatings.
