“Sometimes, water temperatures under 40 levels Fahrenheit for greater than a day trigger issues for noticed seatrout,” also referred to as speckled trout, LDWF fisheries biologist Jason Adriance mentioned in a information launch. Redfish, or purple drum, are “barely extra tolerant and can start to expertise issues when temperatures dip into the mid-30s.”

Adriance defined speedy cooling would have an effect on fish deaths greater than a gradual decline in temperature, as fish can acclimate and transfer to hotter waters. Proof of freeze-afflicted fish populations can typically be onerous to gauge, as frozen fish might not seem for per week or extra after they succumb to the chilly.

Whereas biologists aren’t anticipating extreme impacts to inland fish resembling smallmouth bass or gaspergou, small populations of shad may very well be in danger within the chillier than common waters.

LDWF asks those that come throughout massive numbers of useless or dying fish to contact the division to offer extra particulars.
