A coastguard ship as well as several commercial vessels and two boats operated by NGOs were involved in the operations in the central Mediterranean coordinated by Italy.
The migrants were found mostly on small boats and rafts, though there was also one larger vessel, the coastguard said in a statement.
According to the latest figures released Thursday, nearly 25,100 migrants have arrived in Italy so far this year, a 30 percent increase from the same period last year.
