Cockles threatened
I don't know whether the story about Asians eating wild mallard ducks is true or false, but it is well documented and witnessed that parties of Asians decimated the cockle population of Brisbane Water about 10 years back.
During the 19th century, lime-burners just about wiped out the cockle population.
However, in the 20th century, they started to make a comeback.
Then came another wave of predators: Poor old cockles.
