The Vancouver park board is dealing with more predatory behaviour in one of the city's most popular tourist attractions.
An otter has killed six koi in the Dr. Sun Yat-Sen Classical Chinese Garden, prommpting officials to drain the pond.
Six large and 74 small koi have been relocated.
It comes less than a year after a river otter repeatedly dined on the costly fish, spurring international media attention.
The park board says that it hopes to be able to refill the pond over the next 48 hours, at which time the garden will be reopened.
Last year, park officials were unable to trap an otter that killed 11 koi, including a 50-year-old known as Madonna.
The fish were reportedly valued from $1,000 to $5,000.
When the fish were returned this year, the board said that the garden's access ways had been modified to prevent the otter from making his way back into the area.
