Seals, large percentage of deep-sea fish contaminated by microplastics

Scientists testing North Atlantic mesopelagic fish eaten by the ocean’s top predators found that nearly 75 percent were contaminated with microplastic fibers. Researchers have also discovered microplastics in the scat of gray seals and in the Atlantic mackerel they eat.

Scientists estimate that there could be more plastic than fish in the ocean by weight in 2050. Many of those tiny plastic pieces are not only consumed by marine life at the sea’s surface but also end up inside a large percentage of fish living in much deeper waters of the open ocean, researchers have found.

The findings come as another group of scientists have discovered microplastic fibers in the feces of captive gray seals in the United Kingdom as well as in the digestive tracts of the wild Atlantic mackerel fed to the marine mammals, according to a study published on Thursday in the journal Environmental Pollution
