I am completely new to aquaponics and have lots of beginner questions. I have searched the forums for information on this topic, but didn't find an answer, so I am bringing it to the "Fishy Questions" section.

I want to raise fish that are high in omega-3 fatty acids. I have read that a couple of kinds of perch found in Australia are high in omega-3s, but I don't believe these fish are available in the USA. From what I have gleaned, tilapia and catfish are higher in omega-6 fatty acids, which can actually contribute to poor heart health if they are out of balance with omega-3s. I'd like to find a fish that is high in omega-3s that can be successfully raised in an aquaponics environment.

Thanks in advance for help with this!
