Unexpected Drop In Temperature Kills 2 Million Fishes

The death of two million fish that washed up on the shores of the Chesapeake Bay in Maryland appears to have been caused by an unexpected drop in temperature, the state's Environment Department told Reuters.

The mass kill is the newest in a string of bird and fish deaths around the world. Around 5,000 birds fell out of the Arkansas sky over the New Year's weekend and many dead fish were also found in a diverse part of the state.

Since then, reports of smaller-scale die-offs have been reported in Europe, Brazil, and Asia, causing many to wonder about the cause of the kills.

There is a completely sensible explanation for the Chesapeake deaths, the Maryland Department of Environment said.

"The cause of this appears to be the fast temperature drop combined with the large population of the juvenile spot fish," spokesman Jay Apperson told Reuters on Thursday.

The coldest December in 25 years caused cold water stress to the previously overpopulated species, the department said in a statement.

There have been many such incidents in the past with 2,900 kills afflicting all fish species between 1984 and 2009 according to the department. The main ever die-off was around 15 million in January, 1976. The Chesapeake Bay is the largest estuary in North America.
