Four of the migrants were hospitalised for dehydration while the others, including 14 women, were put up in temporary accommodation in the town's elementary school, according to local mayor Giuseppe Certoma.
Certoma said the town would adopt the baby girl, who was born during the crossing, "as if she was our daughter."
"We have to see if she was born in international or Italian waters, but if she was born in Italian waters we will register her. The important thing is that she is healthy," he said.
Good weather has raised fears of increased numbers of immigrants trying to reach Italy by sea.
