The Louisiana Department of Wildlife and Fisheries (LDWF) reminds the public that increased water temperatures, storms, and extended cloudy weather can lead to fish kills in inland and nearshore waters across the state. These events are typically caused by low dissolved oxygen (hypoxia), which often occurs in warm water, since it has a lower carrying capacity for oxygen than cooler water. Conditions such as stagnant water, heavy rainfall, decaying vegetation, or increased nutrient runoff contribute to hypoxic conditions—especially in shallow bayous, marshes, and ponds.
