This is a great explainer video by The Conservation Fund on land-based fish farming. 90% of US seafood is currently imported and 2x the current supply will be needed by 2050, so there is a growing need for new ways to provide high-quality, local fish without putting more pressure on our oceans. Recirculating Aquaculture Systems (RAS) is one solution, and this is a very informative 2-minutes!
- Land-based RAS is a sustainable, local way to farm healthy fish.
- It uses tanks where water is continuously filtered and recycled and waste can be used as fertilizer for farmers.
- It provides a controlled and traceable environment, without the use of antibiotics or hormones.
- It can be used anywhere, so fish can always be locally grown, helping local economies and providing a fresher product.
- Land-based RAS has minimal impact on the environment, with 1/2 the carbon footprint of imports, and is water efficient, using 99% recycled water + it recycles nutrients and by-products, and conserves wild fish
- Additionally, RAS fish are fed sustainable feeds that don’t require wild caught fish to be used in their feeds, providing a 0% fish-in / fish-out ratio.
