Spain region's fish will be sacrificed for water quality

STORY: Tons of fish are being sacrificed in Catalonia

in an 'exceptional' anti-drought measure

Location: Vilanova de Sau, Spain

Fishing boats were out in force

this week to catch the fish

The move aims to preserve water quality

in the drying Susqueda reservoir

A massive die-off of fish in the low-oxygen water

could contaminate drinking water, local authorities say

Invasive species will be euthanized,

while native ones will be released in nearby waters
