What aquaculture experts tell me about the world’s fastest-growing food source.
- Nigerian catfish are bred so densely you can walk across their ponds.
- “In an urban environment, why not use a rooftop to grow fish in a couple of recirculating ponds?”
- China grows grass carp in quantities equal to the catch of the entire U.S. fishing fleet.
- “Everyone’s working hard to reduce the use of fishmeal and fish oil in feed, and to fool the fish into thinking they are eating what they want.”
- All the tilapia we eat are male, with females forced that way early in life.
- “Many agricultural landscapes are becoming more saline and facing more seasonal inundation from the sea. There’s a big opportunity for aquaculture explicitly to be part of a planned transition that can not only recover but actually dramatically increase the value of these landscapes.”
- Shrimp lack an immune system.
- “In Africa, the sooner we move past small-scale aquaculture, the better. It’s a dead duck.”
- Eight miles off Panama’s Atlantic coast, cobia destined for plates in the United States fatten up in high-tech cages.
- The world needs to grow 30 million more tons of fish each year by 2050: “We mostly know how, but is there a will to do it?”
