According to him, the American lobsters could not thrive in the Baltic and therefore were unable to endanger the local species. Wilson also overruled Sweden's fears of a full-blown invasion as unsubstantiated, describing the trend as "single lobsters escaping."
In March, Sweden asked the European Union to ban the import of live American lobsters, under the pretext of possible contamination of its native species. In recent years, over 30 American lobsters have been discovered off Sweden's west coast, the Swedish government said. Remarkably, Norway has already imposed a lobster ban.
According to Sweden, the spread of disease and parasites, together with interbreeding of species, pose a threat the European lobster's survival. The European lobster is much smaller and more delicate compared to its larger and sturdier American cousin.
"The American lobster can cause a biological collapse of our ecosystems, as soon as they get a grip on our west coast," a concerned Susanne Eriksson, associate professor of marine biology at Sven Lovén Center for Marine Sciences, told Swedish Radio.
"I can understand the concern on the North American part, because it is a major export industry. But when the American lobster is well off on the west coast, it is already too late to act," Susanna Eriksson said.
The export of live lobster from Canada and the US to the EU totaled some 200 million dollars last year, the Swedish newspaper Västerbottens-Kuriren reported.
