Duck is one of the poultry commodities. It produces meat and eggs, which is beneficial to satisfy the needs for animal protein and economic value in increasing family income. Meanwhile, conch can increase the productivity of duck eggs, and it is a relatively cheap source of feed, and widely available in Lake Tondano. The research aims to describe the laying ducks farming and analyze the advantages of laying ducks farming surrounding Lake Tondano, North Sulawesi. The research was conducted in April-June 2023. It used a purposive sampling method to determine the respondents. The general raising system was the same, such as grazing, but it had differences in capital, production costs, revenue, and profits between farmers. The 1st type of laying ducks farming using ready-laying ducks was more profitable (R/C = 1.59) than the 2nd type of laying ducks farming using day-old-ducks (R/C = 1.48). However, this benefit would be greater if the expensed labor was waived.
