Scientists investigate cause of another fish kill in Biscayne Bay

Local 10 News reported on the more than 1,000 fish that died in Biscayne Bay’s northern basin as oxygen levels crashed toward zero, echoing conditions from the 2020 kill that claimed over 27,000 marine creatures. Sampling alongside University of Miami scientists, Miami Waterkeeper traced the collapse to pollution and seagrass loss — up to 90% gone in parts of the basin — with Executive Director Rachel Silverstein warning that “the wildlife is literally suffocating in place” and water quality manager Aliza Karim confirming the water had gone “anoxic.”
