This offers the fish the unofficial title of world's ugliest animal.
The society began as a science-themed comedy night and devised its mascot campaign to draw focus to "aesthetically challenged" threatened species.
The winner was announced for the British Science Festival in Newcastle.
The blobfish tops a list that has the massive-nosed proboscis monkey, the similarly afflicted pig-nosed turtle, an amphibian affectionately termed as "scrotum frog" and pubic lice.
Biologist and TV presenter Simon Watt, president of the Ugly Animal Preservation Society, said he hoped the campaign would draw awareness of the threats facing these weird and wonderful creatures.
"Our traditional way of conservation is egotistical," he told BBC News.
"We merely protect the animals that people relate to because they're cute, like pandas.
"If extinction threats are badly because they seem, then focusing just on very charismatic megafauna is completely missing the point.
"I've nothing against pandas," he added, "however they have their supporters. These species need help."
'What died today?'
Mr Watt said he hoped the vote would also bring a lighter side to conservation.
"It's the most depressing form of science to become involved with," he explained. "It's basically working out: What died today?"
For this campaign, Mr Watt caused comedians, all whom launched a campaign message online for their chosen creature. The society asked people to choose their favourite.
