Dead fish
Thousands of dead fish could be seen in Portland Harbor Saturday.

Acting Portland harbor master Kevin Battle calls it a "fish kill". He says it appears bigger fish like stripers chased smaller fish into the harbor, eating them. When that happens, Battle says the fish use up lots of oxygen and more fish die in the process.

Battle says as many as 10,000 fish were floating in the harbor. He says this is the first time he's seen this in Portland in eight or nine years.
