Haha, i checked the "technology" part of it, nothing. They recycle their water. Yeah, who wouldn't. Absolutely nothing about technology It's extremely expensive to farm fish in a tap water system or any closed system for that matter. That's why nobody really does it. I'm not saying anything more because i don't want to educate these guys here who rob people from their savings. But it's funny that actually nobody here knows if it's pumped sea water, tap water or fresh water from other source what this is based on. And the filtering systems nobody has any idea and there's tons of other stuff related, no clue. None of that is never discussed on Siaf pages/or any info they give. All i can say is tat all the technology and science has been invented already long time ago. This is just an half brain idea for investment, company saying the things investors with little knowledge want to hear.
