An automated offshore fish farm comes to Norway: Giant remote-controlled pens will tend to millions of salmon - [News].

Tucked within Norway's fjord-riddled coast, nearly 3,500 fish pens corral upwards of 400 million salmon and trout. Norway exports more such fish than any other country in the world (1.1 million tons in 2018), and farmed salmon is one of its top three exports. With the global industry expected to quintuple by 2050, farmed salmon is a fine kettle of fish. [ABSTRACT FROM AUTHOR]
