People are eating more #octopus than ever: annual global production has more than doubled since 1980, from roughly 180,000 tons to about 370,000 tons. But overfishing has already caused the collapse of multiple wild-octopus fisheries around the world, and current populations likely face similar threats. Carlos Rosas, a biologist who aims to revolutionize how those gelatinous blobs wind up on dinner tables, believes inland aquaculture—raising the #animals from birth to adulthood in captivity—could be one way to meet increased demand without devastating the wild population, reports Tik Root. The approach has been tried with a variety of other marine animals, such as shrimp, salmon and tilapia, but octopuses have remained a stubbornly vexing puzzle. However, as the stability of wild populations has become more uncertain and the economic stakes have risen, teams in Spain, Japan and elsewhere around the world have also made significant progress on the surprisingly complex science behind octopus rearing. Critics find the prospect of cultivating such sentient animals for food barbaric. They point out that research shows the animals are highly intelligent, exhibiting complex behaviors incompatible with the enclosed environments of aquaculture. Rosas argues that it may actually be the best way to protect the species over the long term. And, hovering between a prototype and commercial scale, he’s at the forefront of the increasingly intense quest to build the world’s first octopus farm. Read more at the link in bio.
