Which method of fishing affeets the resources most?

The method of fishing that affects resources the most is bottom trawling. Bottom trawling involves dragging a large, heavy net along the ocean floor, which can cause significant damage to marine habitats and ecosystems.

Bottom trawling has a number of negative impacts on marine resources, including:

* Bycatch: Bottom trawling nets often catch large amounts of unintended species, called bycatch. Bycatch can include protected species, such as dolphins and sea turtles, as well as juvenile fish that have not yet reached maturity.

* Habitat damage: Bottom trawling can cause significant damage to marine habitats, including coral reefs, seagrass beds, and fragile soft sediments. These habitats are important for providing food and shelter for a variety of marine species.

* Overfishing: Bottom trawling can lead to overfishing of certain species, particularly groundfish like cod, flounder, and halibut. These species are often slow-growing and long-lived, and they can be easily depleted by bottom trawling.

In addition to these direct impacts, bottom trawling can also have indirect impacts on marine resources. For example, by reducing the abundance of certain species, bottom trawling can disrupt the food chain and lead to changes in the composition of marine ecosystems.

Given the significant impacts of bottom trawling on marine resources, there is growing concern about this fishing method. A number of measures are being taken to reduce the environmental impacts of bottom trawling, including:

* Limiting the use of bottom trawling: Some countries have imposed limits on the use of bottom trawling, in certain areas or during certain times of year.

* Promoting the use of alternative fishing methods: There are a number of alternative fishing methods that are less harmful to marine resources, such as hook-and-line fishing and spearfishing. These methods are being promoted as a way to reduce the reliance on bottom trawling.

* Educating fishermen: Fishermen are being educated about the environmental impacts of bottom trawling and encouraged to adopt more sustainable fishing practices.

These measures are helping to reduce the impacts of bottom trawling on marine resources, but more needs to be done. Bottom trawling remains a major threat to marine ecosystems, and it is important to continue working to reduce its use.
