Key Concepts for Healthy Recirculating Aquaculture Systems, RAS Fish Farming

In this video I discuss the key concepts to maintaining a healthy recirculating aquaculture system that you should know. These key RAS concepts include water quality management, water treatment, oxygenation, feeding, biosecurity, and maintenance. The difference between a closed recirculating aquaculture system and semi-closed ras fish farming is discussed along with the factors that impact water quality in RAS fish farming.

Really like the video. Our farm is somewhere in between a closed loop system and semi-closed loop system. Nitrate build up is definitely an issue though. I have been recently trying humic acid and seeing how that affects the biofilters and all 3 nitrogen species. I am hoping to one day add aquaponics as I do not have a huge abundance of water.

Thank you

I loved your video. Very well done. I do have one question/comment. Isn't ionized ammonia LESS toxic to fish, as it cannot pass over the gill membrane as easily? Unionized ammonia binds to the gills and can kill the fish. In your video, according to your graph, there is more UNionized ammonia as the pH becomes more basic, which would mean it is MORE toxic to fish. Can you please clarify? Thank you.

I like the lesson but But the music spous to be back ground instead is too much and annoying
