Recent years have witnessed the impressive and rapid development of brackishwater shrimp pond culture in Johore, Peninsular Malaysia. According to official estimates, there were some 236 brackishwater ponds in operation, spanning an area of 336 ha in 1984. By 1987, the number of ponds had increased to 365 while the area developed was 490 ha. Some 2,500 ha of mangrove areas have been studied for aquaculture potential. Recognizing the tremendous potential of brackishwater pond culture in Johore, there has been an upsurge of interest by the private sector to invest in the aquaculture business, especially in tiger shrimp (Penaeus monodon) farming. In the light of these current developments, this study seeks to determine the economic viability of brackishwater pond culture, with specific reference to tiger shrimp farming on a semi-intensive culture system. More specifically, the study aims to analyze the cost and earning structures of the shrimp farming enterprise; assess the economics of investment in shrimp farming using various profitability indicators; examine the farm's sensitivity to changes in production and price levels; and examine the impact of changes in production and price on the farm's net income. The data in this study were obtained from a cross sectional survey of brackishwater pond operators in Johore during the 1987-1988 crop year.
