Cold empties Bolivian rivers of fish

With high Andean peaks and a humid tropical forest, Bolivia is a country of ecological extremes.

But during the Southern Hemisphere's recent winter, unusually low temperatures in part of the country's tropical region hit freshwater species hard, killing an estimated 6 million fish and thousands of alligators, turtles and river dolphins.

Scientists who have visited the affected rivers say the event is the biggest ecological disaster Bolivia has known, and, as an example of a sudden climatic change wreaking havoc on wildlife, it is unprecedented in recorded history.

Vaccine developed to save fish from deadly parasite

Fish can be immunized against Ich, the dreaded "white-spot" disease that is the bane of home aquarists and commercial fish farmers, government scientists have shown.

Although the team still has many obstacles to overcome, the study presented Friday at a Boston meeting of the American Chemical Society indicates for the first time that a protective vaccine is within reach.

Ichthyophthirius multifiliis, commonly known as Ich, is the most common protozoan parasite of fish.
