Agribusiness Performance of Milkfish and Vannamei Shrimp in a Polyculture System

Abstract

This study analyzes the agribusiness performance of milkfish-vannamei polyculture in Asingi Village of South Konawe District. Data were collected from 15 pond farmers through surveys and direct observation in 2024. Descriptive and financial analysis (Revenue/Cost or R/C ratio) were employed to evaluate the viability of the farming system. The results show that, on average, each farmer produced 4,063 kg of milkfish and 1,737 kg of shrimp per season, generating total revenue of IDR 138.54 million against production costs of IDR 42.44 million. The average net income was IDR 96.1 million per season, yielding an R/C ratio of 3.26, which indicates a highly profitable enterprise. These findings demonstrate that milkfish and vannamei shrimp polyculture is economically feasible. However, analysis of farming practices revealed some suboptimal input management. Improvements in management, such as following best-practice guidelines for input use and risk mitigation, could further enhance productivity and sustainability. With appropriate support and farmer training to optimize input use and manage risks, this integrated farming system can be further developed to improve coastal livelihoods and strengthen the regional aquaculture sector.
