"The debate about coypu has become bonkers, without coming to any resolution of the problem," the 31-year-old mayor wrote. "Here's my idea — let's start eating them in restaurants and at village food festivals."
The mayor said he was speaking from practical experience, having eaten coypu meat. "It's almost better than rabbit," he said.
One enthusiastic backer of the idea wrote: "Coypus are very clean animals and they are herbivores. I've tried them a few times. They should be cooked in a stew with onions or baked in the oven. I agree with the mayor — it's better than rabbit."
Animal lovers were less enamoured of the idea. "Here's another genius who thinks he can resolve a problem by killing defenceless animals. And they elected him mayor," wrote one critic.
Coypu have adapted well to a range of different habitats in Italy. They can even be seen in the middle of Rome, nibbling on sedges on the banks of the Tiber.
They breed prolifically, with a female capable of giving birth to up to a dozen young at a time.
In their native range they are eaten by alligators, large snakes and eagles.
A lack of such predators in Europe has contributed to their rapid population growth.
