India's shrimp exports to the U.S. were once a success story. Now the industry faces ruin amid President Trump's 50% tariff on imports from the country.

The routine closure comes as oysters enter their spawning season.

A lot of Americans learned to shuck oysters and cook fish at home during the pandemic. Now that restaurants are getting back to normal, there's a supply crunch.
