So let’s dive in and discover the key principles behind sustainable fishing methods!

Sustainable Fishing Methods

Traditional Fishing Methods

Handline fishing

handline fishing is a traditional method that has been practiced for centuries. It involves using a single fishing line with a hook attached to the end. You simply hold the line in your hand and drop the hook into the water, then wait for the fish to bite. This method is highly selective, as you have full control over which fish you target. It is also low impact, as it does not involve the use of any heavy equipment or nets that can damage the marine ecosystem.

Trap fishing

Trap fishing is another traditional method that is still used today. It involves placing traps or pots on the ocean floor and waiting for fish to swim into them. Once the fish are trapped, they can be easily harvested. This method is generally considered more sustainable than other forms of fishing, as it allows for the selective harvesting of fish and reduces the chances of capturing non-target species.

Spearfishing

Spearfishing is a traditional method that involves using a spear or a similar device to catch fish underwater. This method requires skill and precision, as the fish need to be approached in their natural environment. Spearfishing is an environmentally friendly method, as it does not involve the use of nets or other gear that can damage the marine ecosystem. It is also highly selective, as you can choose which fish to target.

Cast net fishing

Cast net fishing is a traditional method that involves throwing a circular net into the water and then pulling it back to catch fish that are swimming nearby. This method is commonly used in shallow waters and estuaries. Cast net fishing is a sustainable method, as it is selective and does not involve the use of large-scale fishing gear that can harm the marine ecosystem.

Gillnet fishing

Gillnet fishing is a traditional method that uses a net with small mesh size to catch fish by entangling them. This method is widely used around the world. While gillnet fishing can be effective in catching target fish species, it often results in high levels of bycatch, which refers to the unintentional capture of non-target species such as dolphins, turtles, or seabirds. Therefore, it is important to use gillnets in a carefully regulated and monitored manner to minimize the impact on the ecosystem.

Modern Fishing Technologies

Longlining

Longlining is a modern fishing method that involves setting a long line with baited hooks along the ocean floor. The line can be several kilometers in length and can catch a large number of fish in a single fishing trip. While longlining is highly efficient in catching target species such as tuna or swordfish, it has been associated with high levels of bycatch. To make longlining more sustainable, measures such as using circle hooks and incorporating bird-scaring devices can be employed to reduce bycatch and minimize the impact on non-target species.

Trawling

Trawling is a fishing method that involves dragging a large net along the ocean floor to catch fish and other marine organisms. This method is commonly used for commercial fishing, particularly for species that live close to the bottom. However, trawling can be highly destructive to the seafloor habitat and can result in high levels of bycatch. To make trawling more sustainable, measures such as using turtle excluder devices (TEDs) and modifying gear to reduce bottom contact can be implemented.

Purse seining

Purse seining is a fishing method that involves surrounding a school of fish with a large net and then closing the net to capture the fish. This method is commonly used for catching pelagic fish such as tuna or sardines. Purse seining can be effective in targeting specific fish species, but it can also result in high levels of bycatch. To make purse seining more sustainable, measures such as using fish aggregating devices (FADs) and employing spotter planes can be utilized to reduce the amount of non-target species captured.

Fish aggregating devices (FADs)

Fish aggregating devices, or FADs, are floating objects that are deployed in the ocean to attract fish. They can be as simple as a raft or as complex as a structure designed specifically for this purpose. FADs are often used in combination with other fishing methods, such as purse seining or longlining, to concentrate fish in a specific area for easier harvesting. However, the use of FADs can also result in the bycatch of non-target species, including sharks and turtles. To minimize the impact of FADs, their design and deployment should be carefully regulated and monitored.

Electrofishing

Electrofishing is a fishing method that uses an electric current to stun or immobilize fish, making them easier to catch. It is commonly used for scientific research or in fish farms. Electrofishing can be a selective method, allowing for the targeted capture of certain fish species. However, it can also result in the injury or mortality of fish if not used properly. Therefore, the use of electrofishing should be carefully regulated and only employed for specific purposes where alternatives are not feasible.

Selective Fishing Techniques

Size and species selectivity

Size and species selectivity refers to the ability to target specific fish species or sizes while avoiding the capture of non-target species or undersized fish. Various fishing gear modifications and techniques, such as using different mesh sizes or incorporating escape rings, can help achieve this selectivity. By targeting only mature fish of the desired species, fishing practices can have a lower impact on the overall population and maintain a healthy and sustainable fishery.

Escape panels

Escape panels, also known as bycatch reduction devices, are openings or panels incorporated into fishing nets or traps that allow non-target species to escape. These panels are specifically designed to release fish that are too small or of the wrong species, ensuring they can continue to grow and reproduce. By using escape panels, fishermen can minimize the amount of bycatch and contribute to a more sustainable fishing practice.

Modified gear

Modified fishing gear refers to any alterations made to fishing equipment to reduce bycatch and minimize the impact on the marine ecosystem. This can include changes to mesh sizes, the addition of acoustic deterrents, or the use of modified hooks to increase selectivity. By adjusting fishing gear to target specific fish species and avoid non-target species, fishermen can significantly reduce their environmental impact and help sustain fish populations.

Bycatch reduction devices

Bycatch reduction devices are technologies or methods designed to minimize the capture of non-target species in fishing operations. Examples of bycatch reduction devices include turtle excluder devices (TEDs) and shark shields. These devices allow non-target species to escape from fishing nets or gears, reducing mortality and preserving biodiversity. By incorporating such devices in fishing activities, fishermen can play a crucial role in safeguarding marine ecosystems.

Real-time monitoring

Real-time monitoring involves the use of technology to track and record fishing activities while they are happening. This can include the installation of onboard cameras or the use of satellite transmitters to monitor fishing vessels. By implementing real-time monitoring systems, it becomes easier to ensure that fishing practices align with sustainable guidelines and regulations. This approach also enables prompt intervention in cases of illegal, unreported, and unregulated fishing, contributing to the protection of marine resources.

Ecosystem-based Approaches

Marine protected areas

Marine protected areas (MPAs) are designated areas of the ocean that are protected from fishing and other extractive activities. These areas aim to preserve marine biodiversity, protect critical habitats, and allow fish populations to recover. By creating MPAs, governments and conservation organizations can promote sustainable fishing practices and protect vulnerable marine species, ultimately contributing to the long-term health of the ocean ecosystem.

Habitat restoration

habitat restoration involves the active efforts to restore and rehabilitate degraded or damaged marine habitats. This can include initiatives such as coral reef restoration, seagrass bed rehabilitation, or the establishment of artificial reefs. By restoring habitats, fishermen can help replenish fish populations and create healthier marine ecosystems. Habitat restoration projects often involve collaboration between fishermen, researchers, and conservation organizations to ensure their success.

Fishing gear modifications

Fishing gear modifications can play a significant role in reducing the environmental impact of fishing activities. By incorporating changes such as larger mesh sizes, escape panels, or acoustic deterrents, fishermen can increase selectivity, minimize bycatch, and reduce habitat damage. These modifications can be tailored to specific fishing practices or target species, making them an effective tool for promoting sustainable fishing practices.

Seasonal fishing closures

Seasonal fishing closures involve the temporary prohibition of fishing in certain areas or during specific times of the year. These closures can be implemented to protect spawning grounds, sensitive habitats, or endangered species during critical periods of their life cycles. By respecting and adhering to seasonal fishing closures, fishermen contribute to the overall sustainability of fish populations and ensure that the ocean ecosystem is given the opportunity to replenish and thrive.
