Abstract: Abstract:Aquaculture is not only a biological activity but also an economic activity. The present farming management of grouper ranging in stocking density from 0.88 to 3.00 (× 10^4 fingerling per gia) would not have a significant effect on the survival rate. However, increasing the stocking density but within the present limits may increase the productivities in feed and water but reduce that in fingerling. Three optimal ranges of stocking density for the grouper farming in Taiwan were therefore statistically estimated based on the concerns of varied productivities. The upper and lower limits in stocking density were 2.3556 (± 0.086555) × 10^4 fingerling per gia to obtain an optimal productivity in feed and water. The optimal stocking density should be lowered to a range of 1.5778 (± 0.14256) × 10^4 fingerling per gia if the fingerling productivity is a major concern. However, controlling the stocking densities within a range of 2.0778 (± 0.1376) × 10^4 fingerling per gia would receive the highest total revenue and net revenue, and therefore would be the most profitable.
