The flooding Mississippi River is taking a major toll on Louisiana’s commercial fisheries.

Many of the state’s fisheries, like shrimp and oysters, need a mix of salty and fresh water to grow properly. But because of the months-long flooding on the Mississippi River and the opening of the Bonnet Carre Spillway -- through which water has been flowing for more than 70 days this year -- many of those areas are now too fresh.

The Mississippi River has been at flood stage for months. Levees and spillways keep most homes and businesses safe and dry from the flood waters, but the high water still creates headaches for levee districts and industries like oil and gas, and fisheries.

This week on the Coastal News Roundup, WWNO coastal reporter Travis Lux went to find out how the river creates problems we can’t always see. WWNO’s Tegan Wendland got the details.

A report out this month says that the world’s oceans are warming much faster than expected. That’s already causing some fish species to move north, and could bring more changes to the ocean in the future.

To better understand how this will impact Gulf of Mexico fisheries like shrimp, snapper, and oysters, WWNO’s Travis Lux spoke with Dr. Rebecca Selden, a Marine Ecologist at Rutgers University.

The bounty of the Louisiana Coast has helped make New Orleans a food capital. But humans have put the once-plentiful resources — like fish — at risk. 

On this week's coastal news roundup, Nola.com/Times-Picayune environmental reporters Sara Sneath and Tristan Baurick talk about how chefs, fishermen and companies are fighting to keep Louisiana on the food map.
