Scourge of goldfish has become growing problem as fish are released by pet owners into increasingly warm waters
City officials in Canada’s capital city, Ottawa, plan to cull thousands of feral goldfish from a stormwater pond, a decision that reflects the pervasive spread of the species throughout the region.
Earlier in the year, city staff removed 5,000 fish from the city’s Celebration Park. But as many as 1,000 more are believed to still be living in the water.
