The study, published in Environmental Pollution, found that herring larvae ingest plastic particles through their mouths and gills, and that the particles can then accumulate in their digestive tracts.
This is the first time that researchers have been able to observe and quantify the ingestion of plastic particles by fish larvae, and the findings could have important implications for understanding the impacts of plastic pollution on marine life.
The researchers used a combination of laboratory experiments and field observations to study the ingestion of plastic particles by herring larvae.
In the laboratory experiments, they exposed herring larvae to different concentrations of plastic particles and observed how many particles were ingested by the fish.
In the field observations, they collected herring larvae from the wild and analyzed their digestive tracts to see if they contained plastic particles.
The results of the study showed that herring larvae can ingest plastic particles through their mouths and gills, and that the particles can then accumulate in their digestive tracts.
The researchers found that the number of plastic particles ingested by herring larvae increased with the concentration of plastic particles in the water.
They also found that the size of the plastic particles ingested by herring larvae decreased with the age of the fish, suggesting that younger fish are more likely to ingest smaller plastic particles.
The findings of this study could have important implications for understanding the impacts of plastic pollution on marine life.
Plastic particles can be harmful to fish and other marine organisms, and can cause a variety of health problems, including reduced growth, impaired reproduction, and death.
The accumulation of plastic particles in the digestive tracts of herring larvae could also affect their ability to feed and survive.
