From small-scale efforts to large-scale policy change, there are many ways we can work together to protect marine life from the impact of commercial fishing. By supporting sustainable practices and advocating for change, we can ensure that our oceans remain healthy and vibrant for generations to come.
Together, we can make a difference.
The Devastating Impact of Bycatch
Bycatch, the unintended capture of non-target species, is a widespread problem in commercial fishing that has far-reaching consequences for marine ecosystems. Every year, an estimated 40% of global catch is bycatch, with up to 300,000 cetaceans alone dying as bycatch. These numbers are alarming, and they highlight the urgent need for action to address the problem.
Bycatch occurs in a variety of fishing methods, including trawling, gillnetting, and longlining, with each method causing different species to become entangled. The impact of bycatch can be devastating, leading to declines in populations of species that are already threatened or endangered. It also affects the overall health and balance of marine ecosystems.
The Impact of Bycatch on Marine Mammals
- Marine mammals, such as dolphins, porpoises, and whales, are often unintentionally caught in fishing gear.
- These animals can drown or sustain injuries that impact their ability to hunt or reproduce.
- Bycatch is one of the leading threats to many marine mammal species, and it has contributed to the decline of populations around the world.
The Impact of Bycatch on Sea Turtles
- Sea turtles are also frequently caught in fishing gear, particularly in longlines and gillnets.
- They can suffocate or sustain injuries that impact their ability to swim and hunt for food.
- All seven species of sea turtles are listed as threatened or endangered, and bycatch is a major threat to their survival.
The Impact of Bycatch on Sharks
- Sharks are often caught as bycatch in commercial fishing, particularly in longline and gillnet fisheries.
- Many shark populations have declined by 90% or more due to overfishing and bycatch.
- Sharks play a critical role in maintaining the balance of marine ecosystems, and their decline could have significant ecological consequences.
Bycatch is a serious problem that requires immediate attention and action. Addressing the issue will require a combination of approaches, including improving fishing gear design, implementing stronger regulations and enforcement, and promoting sustainable fishing practices. It is our responsibility to protect marine ecosystems and the countless species that call them home.
What Are Fishing Nets Doing to Our Oceans?
Fishing nets have been a critical tool in the commercial fishing industry for centuries. Unfortunately, modern fishing practices have taken a significant toll on our oceans, with the use of these nets contributing to a variety of environmental issues.
One of the most pressing problems associated with fishing nets is their impact on marine wildlife. Nets are indiscriminate, catching not only the target species but also unintended animals in a process known as bycatch. This includes species like sea turtles, sharks, dolphins, and seabirds, which can suffer injury or death as a result of being caught and trapped in the nets. The effects of bycatch can be devastating, leading to population declines and even extinction of some species.
Ghost nets are a particular problem in our oceans. These are nets that have been lost or abandoned in the water and continue to drift, trapping and killing marine life for years. Ghost nets contribute to the problem of bycatch and also harm important marine habitats such as coral reefs and seagrass beds, which can become entangled and damaged by the nets.
The use of fishing nets also contributes to the growing problem of plastic pollution in our oceans. Many modern fishing nets are made from synthetic materials like nylon, which do not biodegrade and can persist in the marine environment for centuries. Discarded nets, known as ghost gear, can drift for years and cause significant harm to marine life as well as polluting our beaches and coastal ecosystems.
Sustainable Fishing Practices
While the problems associated with fishing nets are significant, there are efforts underway to promote more sustainable fishing practices. This includes innovations like biodegradable nets and better management of fishing fleets to reduce the amount of bycatch. By supporting sustainable fishing practices and reducing our reliance on harmful fishing practices, we can help protect the health of our oceans and the animals that call them home.

By taking action to protect these incredible creatures, we can help ensure that they continue to thrive in our oceans for generations to come.
How Does Bycatch Affect Local Fishing Communities?
Bycatch, the accidental capture of non-targeted marine species, can have a significant impact on local fishing communities. The practice not only results in the needless killing of millions of marine animals each year, but it can also affect the long-term sustainability of fisheries.
When non-targeted species, such as dolphins, sea turtles, and sharks, are caught in fishing nets, they are often injured or killed in the process. This can have a devastating impact on local ecosystems and the marine food web. Additionally, when fishing fleets are forced to throw away large quantities of bycatch, it can lead to economic losses for local communities and increase fishing pressures on targeted species.
The Economic Impact on Fishing Communities
Bycatch can have a significant economic impact on fishing communities. When fishing fleets are forced to discard large quantities of bycatch, it can result in lost income and wasted resources. Additionally, the need to catch more fish to make up for lost income can lead to overfishing and further depletion of fish stocks. This creates a vicious cycle that can be difficult to break.
The Environmental Impact of Bycatch
Bycatch not only affects the marine species that are accidentally captured, but it can also have broader environmental impacts. For example, the killing of sea turtles, which are important predators of jellyfish, can result in an increase in jellyfish populations, which can have negative effects on local fisheries and tourism industries. Additionally, the removal of non-targeted species from the marine food web can have far-reaching ecological consequences.
Efforts to Reduce Bycatch
- One of the most effective ways to reduce bycatch is to use more selective fishing methods, such as using hooks instead of nets.
- Regulations and policies can also be put in place to limit the amount of bycatch allowed or to require the use of specific fishing gear that reduces the amount of bycatch.
- Technology, such as acoustic deterrent devices and LED lighting, can also be used to deter non-targeted species from fishing gear.
Overall, bycatch is a complex issue that affects both the environment and local fishing communities. Efforts to reduce bycatch are critical to ensuring the long-term sustainability of fisheries and protecting marine ecosystems.
