Aquaculture Issues

Aquaculture or “fish farming” under the right conditions can be a viable part of the solution to the increasing pressure on our oceans’ resources and in meeting the demand for seafood by our growing population. However, aquaculture practices should not come at the expense of a healthy ocean.

Aquaculture has been practiced for more than a thousand years, but it is the last 30 years that we have seen an unprecedented expansion of fish farming, making this sector a substantial contributor to global food supply. Today, half of our seafood comes from aquaculture.

The types of farmed seafood can vary from oysters, prawns to salmon. But not all farmed seafood is created equal or sustainable for that matter. The environmental impact of aquaculture depends on the species, the location of the farm and how they are raised. When the environment is considered, strong management practices are implemented and good practices are used, it is possible to raise sustainably farmed seafood.


Important factors for sustainable farmed seafood, or aquaculture, are:

  1. using production methods that do not harm wild fish or damage ecosystems,
  2. choosing species that are low on the food chain so they add more seafood to the food supply than they use (i.e. vegetarian-based diets over fishfeed-based), and
  3. ensuring management and regulations are effective.
