We tried this with lionfish in the Caribbean; it is just really challenging to catch them in a non-destructive way so they are economically viable. And IMO they don’t taste very good unless fried, at which point everything tastes the same.
There's always animal feed, or to be used for fat or protein isolates
Yes, but sending a human scuba diver down 3h/day to catch max 20kg of lionfish for $50-100 on loaded cost per dive, or $150-300/day is...not an efficient solution for that. If the fish could be sold at enough of a premium it might defray some of those costs, but for animal feed you'd be about $0.50/kg.
killing robots -> harvesting robots
Yeah, robots might dramatically reduce the cost, making it viable.
Was wondering if this robot could kill lionfish as well.
