Plastic's Impact On Fish: A Worrying Reality

Plastic pollution in the ocean is a global crisis. Billions of pounds of plastic can be found in swirling convergences that make up about 40% of the world's ocean surfaces. A recent study published in the journal Global Change Biology revealed that the rate of plastic consumption by marine fish has doubled in the last decade and is increasing by more than 2% a year. The study also revealed new information about what species are most affected and where the risks are greatest.

The rate of plastic consumption by marine fish has doubled in the last decade

A study published in the journal Global Change Biology revealed that two-thirds of all marine and estuarine fish species had ingested plastic. Of these, 210 were species that are commercially fished. This number is likely an underestimate, according to researchers.

The research also revealed that the majority of the species they found to have ingested plastic remain abundant. However, 35 species were listed as threatened or near-threatened, and another 26 species are vulnerable to overfishing. The blue shark, Atlantic bluefin tuna and chinook salmon were identified as "species of high concern due to their threatened status, vulnerability to overfishing and frequent plastic ingestion".

Overall, the likelihood of plastic ingestion decreases with depth, but even so, the bioaccumulation of plastic and its associated chemicals can cause health problems for marine life.

The effect of ingested plastic on fish and marine ecosystems

The study also revealed new information about which species are most affected and where the risks are greatest. The researchers found that two-thirds of all species (386 species) had ingested plastic, with 210 of these being commercially fished species. This number is likely an underestimate, as the researchers' ability to detect smaller particles of plastic improves, more species are found to have ingested plastic. The research revealed that the majority of the species they found to have ingested plastic remain abundant, but 35 species were listed as threatened or near-threatened, and another 26 are vulnerable to overfishing. The blue shark, Atlantic bluefin tuna, and chinook salmon were identified as species of high concern due to their threatened status, vulnerability to overfishing, and frequent plastic ingestion.

The bioaccumulation of plastic and its associated chemicals can cause health problems for fish, and this has a direct and deadly effect on wildlife. Thousands of seabirds, sea turtles, seals, and other marine mammals are killed each year after ingesting plastic or getting entangled in it. Endangered wildlife, such as Hawaiian monk seals and Pacific loggerhead sea turtles, are among nearly 700 species that eat and get caught in plastic litter.

Overall, the likelihood of plastic ingestion decreases with depth, but as plastic accumulates in our oceans and on our beaches, it becomes a global crisis. While little is known about how ingested plastic affects fish and marine ecosystems, it is clear that plastic pollution has a significant impact on marine life and ecosystems.

The effect of ingested plastic on human health

The bioaccumulation of plastic and its associated chemicals can have detrimental effects on fish health, and potentially on human health as well. While it has not caused noticeable fish population problems yet, it is a growing concern. Certain species, such as the blue shark, Atlantic bluefin tuna, and chinook salmon, are of particular concern due to their threatened status, vulnerability to overfishing, and frequent plastic ingestion.

The impact of ingested plastic on human health is not yet fully understood. However, as humans are at the top of the food chain, there is a risk of consuming contaminated fish, which may have adverse effects on our health. The chemicals associated with plastic, such as bisphenol A (BPA) and phthalates, can interfere with hormonal balance and have been linked to reproductive issues and developmental problems in humans.

Additionally, the presence of microplastics in the environment is a growing concern. Microplastics are tiny plastic particles that can be ingested by fish and other marine organisms. These particles can absorb and release toxic chemicals, which can then enter the food chain. While the full extent of the health risks associated with microplastics is not yet known, there is a growing body of research suggesting that they can have negative effects on human health, including potential impacts on the immune system and the gut microbiome.

While more research is needed to fully understand the impact of ingested plastic on human health, it is clear that plastic pollution in our oceans is a significant issue that requires urgent attention. Reducing plastic waste, improving waste management practices, and developing sustainable alternatives to plastic are crucial steps towards mitigating the potential health risks associated with plastic ingestion.

The species most affected by plastic consumption

A study published in the journal *Global Change Biology* found that two-thirds of all marine and estuarine fish species (386 species) had ingested plastic. Of these, 210 were commercially fished species. The study also found that the rate of plastic consumption by marine fish has doubled in the last decade and is increasing by more than 2% a year.

The authors of the study also identified three-quarters of commercially fished species as having ingested plastic. This includes species common in recreational fisheries and aquaculture that are likely to be part of the supply chain.

Overall, the likelihood of plastic ingestion decreases with depth. However, the bioaccumulation of plastic and its associated chemicals can cause health problems. While this isn't causing noticeable fish population problems yet, 35 species were listed as threatened or near-threatened, and another 26 species are vulnerable to overfishing.

Billions of pounds of plastic can be found in swirling convergences that make up about 40% of the world's ocean surfaces. At current rates, plastic is expected to outweigh all the fish in the sea by 2050.

Overall, the likelihood of plastic ingestion decreases with depth. Although bioaccumulation of plastic and its associated chemicals can cause health problems, this isn’t causing noticeable fish population problems yet. Little is known about how ingested plastic affects fish and marine ecosystems, and even less about how human health could be affected when plastic-eating fish end up on our plates.
