Grow-out performance of second-generation Epagri Tilapia strain, also called GIFT-Epagri SC02, was evaluated in the northern and middle Itajaí Valley regions. The zootechnical and economic performance of two commercial cultures for the 2016/2017 harvest and two other commercial culture for the 2017-2018 harvest was followed up. Fingerlings were derived from Epagri and producers hailed from the municipalities of Massaranduba, Timbó and Gaspar. Tilapia reached a final weight ranging between 670 and 1000g in 7-12 months. Cultivation reached a productivity of 18 – 47 tons hectare year-1. The economic performance reached a net profit between R$25,000 and R$53,000 hectare year-1, except for culture in Timbó due to high feed conversion caused by problems concerned to survival and feed management.
