Abstract
Stocking density is considered to determine production and profit in white leg shrimp aquaculture. This research purpose was to determine the optimal stocking density to maximize profit at the culture of whiteleg shrimp in Kolaka Regency, Indonesia. An econometric model approach was established to predict the impact of changes in stocking density on shrimp production and farmer^s profit. The model was estimate dusing the Two-Stage Least Squares (2 SLS) method. Factors that significantly affected the production of white leg shrimp were total Feed, dan culture period. The total feed were effected by stocking density, culture period, and total probiotic. Where as factors that significantly effected the farmer^s profit were production number, feed costs, labor costs, selling price, cultivation system and pond soil base. The model showed that maximum production and profit of whiteleg shrimp culture will be achieved if farmers increased the stocking density by 200 percent from the current stocking density to 99 shrimp juveniles per meter square pond.
