The production of catches of small-scale fishermen in the west coast of Barru District, South Sulawesi Province, Indonesia has fluctuated due to changes in the seasons each year. Changes in catch production have an impact on the household economy such as household income and consumption expenditure. This study aims to estimate the factors that influence the production of smallscale fishermen's catches. The analytical method used by Cobb-Douglas production function equation with the qualitative independent variable regression estimation model with cross-section data. The respondents were small scale outboard motorized fishermen with 69 longline fishing gear and the sample area was all sub-districts directly adjacent to the coastal area of Barru District. The results of the study found that the catch production of small-scale fishermen was influenced positively by the length of the sea, the strength of outboard engines, and differences in regional differences in area, then negatively affected by gasoline, recent education, and family dependents, while fishing gear, kerosene, and age of fishermen no significant effect. The use of fuel oil, such as gasoline and the Grosstonase-powered marine fleet, is needed to reach further fishing ground and fishing gear that is not destructive to the marine ecosystem and is environmentally friendly to increase catches needs to be considered by policy makers and stockholders to improve the welfare of small-scale fishermen.
