Fish are dying in this East Bay park. But why?
Dead fish, nearly all carp, are floating to the surface at Lakeshore Park, and city officials wonder why. They also question why so many carp, a freshwater fish native to Asia and Europe, ended up in the human-made lake in the first place. Carp is an edible fish consumed around the world. It’s also popular as an ornamental fish that people keep in tanks and ponds. Koi is a subspecies.
