The sources, who spoke on condition of anonymity due to restrictions on speaking to the media, said 44 irregular migrants were seized in a sailboat in the Aegean Sea off the coast of western Mugla province.
The migrants were trying to cross to Greece, sources said.
In eastern province of Van and Erzincan, security forces rounded up 69 irregular migrants.
Separately, border forces held 29 Syrians, who were trying to illegally enter Turkey in southern Hatay province, the sources added.
Turkey has been the main route for refugees trying to cross into Europe, especially since the beginning of the civil war in Syria.
Some 205,000 irregular migrants were held in Turkey in 2018 as of Oct. 15, according to the Interior Ministry.
The irregular migrants were mostly Afghan, Pakistani, Syrian and Iraqi nationals.
