Marine Debris Research: What Happens When Salmon Eat Foamed Plastic?

After the 2011 tsunami in Japan, the Alaskan coastline experienced a rise in debris washing ashore. Although there was an increase in many types of debris, the abundance of expanded polystyrene (think foamed plastic) increased on some beaches by as much as 1,600% from 2008 to 2012. This spurred interest by NOAA scientists at the Auke Bay Laboratory in Juneau, Alaska, to explore the interaction between this foam debris and an important Alaskan fishery species: pink salmon (Oncorhynchus gorbuscha). The researchers were interested in both determining the potential of juvenile pink salmon to ingest small foam pieces and understanding the physiological consequences of ingesting foam debris (such as, would ingesting foam alter their growth rates?). Through support from the NOAA Marine Debris Program, the team began an experimental study to address these questions.

Removing Marine Debris in Alaska

Although preventing marine debris is the ultimate solution, removing debris as it accumulates on our shores is an unfortunate necessity. In Alaska, there are currently some pretty cool removal efforts underway to clean up Alaska’s coasts, which are often remote and difficult to access.

The Island Trails Network (ITN) is addressing the issue of debris in remote areas in an innovative and unique way! This effort focuses on Shuyak Island, an area rich in biodiversity that’s located in the western Gulf of Alaska. This location is exposed to high winds and strong currents that cause marine debris to build up, but also make it difficult to access. To solve this problem, ITN recruited qualified volunteers from around the world to come to Alaska and clean the shoreline using sea kayaks, collecting debris and moving it to more easily-accessible areas, where it is later removed and analyzed. 

Blue Fox Bay Lodge Marine Debris Cleanups

In 2012, through the outreach efforts of the Marine Conservation Alliance (now administered by the Sitka Sound Science Center), we were selected to receive a grant to remove marine debris from the remote beaches in this area. During the next three years, our efforts continued with the support of the NOAA Marine Debris Program, a private grant, and the Alaska Department of Environmental Conservation, with funding provided by the Japanese government to clean up tsunami-related debris. Along with a few volunteers, we have removed over 32,000 pounds of varying debris.
