Shreveport, LA – With winter-like temperatures settling across Louisiana and an arctic blast sweeping through the state, the Louisiana Department of Wildlife and Fisheries (LDWF) has issued a warning about potential fish kills in coastal areas due to freezing water temperatures.
Fish kills, if they occur, may not be immediately apparent, as fish might not surface for a week or more following a cold event. Coastal species particularly vulnerable to cold stress include Sand Seatrout (White Trout), Red Drum, Black Drum, and Spotted Seatrout.
“Water temperatures below 40 degrees Fahrenheit for more than a day can significantly impact Spotted Seatrout, while Red Drum are slightly more tolerant, facing issues when temperatures dip into the mid-30s,” said LDWF fisheries biologist Jason Adriance. He noted that gradual cooling allows fish to acclimate and potentially survive.
While inland fisheries biologists do not anticipate severe impacts on freshwater sport fish, small, isolated kills of shad may occur. These instances are unlikely to significantly affect populations.
LDWF urges the public to report any significant fish kills. Reports can be submitted through the Department’s website, including details such as location, approximate quantity and species, and the condition of the fish.
Anglers are reminded that creel and size limits, as well as legal methods of take, remain in effect. Harvesting fish outside of these regulations is prohibited.
