What is Fishing and Aquaculture?
Within Earth & Environmental Science, which covers our planet, its resources and ecosystems, and how people can protect the environment, this topic explains Fishing and Aquaculture. Earth and environment topics show how the planet’s systems shape landscapes, climate and life, with models that make these processes visible.
Check that you can explain Fishing and Aquaculture in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Fishing and Aquaculture helps you explain the environment around you and weigh up how people can protect it.
Fishing and Aquaculture in detail
Fishing provides food and jobs for hundreds of millions of people, but about a third of fish stocks are overfished, caught faster than they can reproduce. Industrial methods, such as bottom trawling, can destroy seabed habitats and catch unwanted species (bycatch).
Management includes quotas, minimum net sizes, closed seasons, marine protected areas and certification such as MSC. Aquaculture (fish farming) now supplies about half of the fish we eat, and takes pressure off wild stocks, but can cause pollution, disease spread, escapes and the use of wild fish as feed. Sustainable seafood choices and better regulation help protect the oceans.
