The fishing industry is one of the biggest contributors to ocean pollution, with commercial fishing and aquafarming being the largest culprits. Overfishing, caused by pervasively illegal fishing, is a significant issue, with some estimating it to be up to 30% of catches for high-value species. In addition, the industry has been accused of hiding its environmental impact from consumers, with fish farms confining animals to tightly packed spaces filled with waste, antibiotics, and pesticides, which contribute to the spread of diseases in the water. Abandoned fishing gear, also known as ghost gear, is another major source of ocean plastic pollution, making up an estimated 10% of all ocean debris. It is particularly deadly, entangling and killing marine life and damaging coral reefs and other important habitats. With the health of the oceans deteriorating, it is clear that ocean pollution is hurting the fishing industries.

Abandoned fishing gear
Ghost gear is particularly deadly to marine life, as it can entangle and kill various species, including small fish, crustaceans, endangered turtles, seabirds, and even whales. It can also damage important habitats such as coral reefs, grass beds, and salt marshes, and release toxins and chemical pollutants that harm the entire food web. When these materials break down, they turn into microplastics that can be consumed by marine species.
The impacts of abandoned fishing gear are not limited to the environment but also have socioeconomic consequences. It poses a threat to food security and affects the livelihoods of those who depend on fishing as a source of income. Additionally, the presence of ghost gear can obstruct navigation and fishing activities, further impacting the fishing industry.
To address the issue of abandoned fishing gear, organizations like Greenpeace and WWF are advocating for global action and collaboration. They are working with fishers, government agencies, and other stakeholders to remove abandoned nets, establish gear collection and recycling programs, and develop tools for better gear management and tracking. Efforts are also being made to improve the sustainability of fishing practices and hold the fishing industry accountable for its waste.
While the fishing industry itself needs to take responsibility for its impact on ocean pollution, individual anglers can also make a difference by incorporating ocean-friendly practices, such as using non-toxic weights and artificial bait, and supporting studies and legislation aimed at mitigating ocean pollution. By working together, it is possible to reduce the negative impacts of abandoned fishing gear on our oceans and the fishing industry.

Overfishing
One of the main issues with overfishing is that it disrupts the delicate balance of marine ecosystems. When too many fish are removed from the ocean, it can lead to a loss of important marine life, including vulnerable species such as sea turtles and corals. This, in turn, can impact the food web and cause a decline in biodiversity. As a result, the health of marine ecosystems is compromised, and the fishing industry suffers as fish stocks decline.
Illegal, unreported, and unregulated (IUU) fishing also contributes to overfishing. This type of fishing ignores governmental and international regulations and can occur in protected zones. IUU fishing is estimated to net criminals up to $36.4 billion each year and is a significant driver of the decline in fish stocks.
To address overfishing, various organizations, such as the World Wildlife Fund (WWF) and the Marine Stewardship Council (MSC), are working to improve fishing practices and promote sustainability. The WWF advocates for the elimination of harmful fishing subsidies and the creation of well-managed marine protected areas. The MSC works with fisheries to achieve certification against an environmental standard, ensuring sustainable fishing practices.
While overfishing is a significant problem, there has been progress in the availability of sustainable seafood. Consumers are increasingly empowered to make sustainable choices, and the FAO Blue Transformation report found that 82% of fish landings by volume come from sustainably managed stocks.

Aquafarming
The migratory characteristic of some farmed fish, such as salmon, has also helped transmit diseases between farmed and wild species. The transmission of disease between farmed and wild fish is a risk when finfish aquaculture operations are in the marine environment, as water moves freely between farms and the ocean. Fish are also reared at higher densities than in nature, increasing contact between fish, and infected fish are not removed as promptly from the farm as they would be by natural predators.
However, it is important to note that some measures are being taken to reduce the negative impacts of aquafarming. For example, most states have regulations requiring fish and shellfish to be screened before they are transferred to another site or released into the wild, and many farmed fish are vaccinated against diseases that have caused problems in the past. Antibiotics are rarely used and, if required, are strictly regulated and always administered under the supervision of a veterinarian. Additionally, alternative feeds that do not rely on pelagic fish are becoming the norm in commercial feeds, which may decrease the industry's impact on the environment.

Ocean plastic pollution
One of the major contributors to ocean plastic pollution is abandoned, lost, or discarded fishing gear, also known as "ghost gear." This equipment, including nets, lines, pots, and traps, makes up a significant portion of the large plastic littering the oceans. It is designed to catch and kill fish, and when lost or discarded, it continues to trap and kill marine animals, such as fish, crustaceans, sea turtles, seabirds, and even whales. Abandoned commercial fishing gear is estimated to account for 10% of all ocean debris, with nets alone constituting 86% of the plastic waste in the Great Pacific Garbage Patch.
The presence of plastic in the oceans has severe consequences for marine life. It leads to ingestion and entanglement, causing injuries and deaths. Sea turtles, for example, can mistake floating plastic garbage for food, resulting in choking and internal injuries. Additionally, plastic ingestion reduces the storage volume of their stomachs, leading to starvation. Research indicates that half of the sea turtles worldwide have ingested plastic, and it is estimated that by 2050, 99% of all seabird species will have eaten plastic.
The impact of ocean plastic pollution extends beyond marine life. Fish in the North Pacific ingest 12,000 to 24,000 tons of plastic each year, transferring it up the food chain to larger fish, marine mammals, and eventually human seafood eaters. This pollution has led to calls for global action and the need to address the issue at its source, including regulating plastics as pollutants and reducing the use of single-use plastics.

Illegal fishing
Illegal, unreported, and unregulated (IUU) fishing is a global issue that threatens ocean ecosystems, sustainable fisheries, and the economic security of those reliant on fishing. It is a key driver of overfishing, which significantly depletes ocean wildlife populations and marine ecosystems. IUU fishing also puts food security and regional stability at risk, with developing countries that depend on fisheries for food security and export income being the most vulnerable.
IUU fishing activities violate both national and international fishing regulations. Those who engage in IUU fishing avoid the costs of sustainable practices and may benefit economically from exceeding harvest limits. As a result, their products can outcompete law-abiding fishermen and seafood industries in the marketplace. The United States, one of the largest seafood importers, has made combating IUU fishing a top priority. In 2016, the US government established the Seafood Import Monitoring Program to address IUU fishing products entering the market.
IUU fishing is estimated to net criminals up to $36.4 billion each year. The lack of systems to track fish from catch to consumer, or "traceability," is a significant challenge in combating IUU fishing. Organizations like the WWF are working to improve traceability in the seafood supply chain and develop unified frameworks to facilitate information flow.
IUU fishing is linked to major human rights violations and even organized crime. Crew members on IUU fishing vessels often come from poor and underdeveloped regions and work in unsafe conditions. The full economic impact of IUU fishing is difficult to quantify, but it likely results in billions of dollars in losses annually.
IUU fishing is a critical issue that threatens the sustainability of marine resources, the livelihoods of coastal communities, and the food security of millions of people worldwide. Addressing IUU fishing through improved regulations, collaboration, and traceability systems is essential to protecting our oceans and those who depend on them.
