That $15 all-you-can-eat shrimp plate, how is that possible?” Bigelow asks. “What’s happening in those pens, on that production line, that makes it possible to raise an animal on the other side of the world and ship it over for less than it costs to grow here?”
Energy – the US cannot afford to heat up shrimp farms like in the tropics.
Labour – Farms in these countries have lower salary requirements.
Seedstock – there are no endemic tropical shrimp stocks in USA – so everything has to be artificial.
Logistics – cheaper to ship a reefer container from South America or SE Asia than to truck it around USA.
Lastly, and shows he is no subject matter expert – shrimp are not grown in pens!
