Abstract
Barramundi (Lates calcarifer) is one of main catches fish in the demersal category. Ecosystem condition is assessed to predict the growth rate of Barramundi. Therefore, the ecosystem condition is being modeled, includes nutrient, phytoplankton, zooplankton, and detritus (NPZD) and their interaction with Barramundi as the highest predator on the food chain. The result shows that the growth rate of Barramundi is 4.07 gram/day with the fastest growth rate (latest) occurs if the seed is stocked in August (November) with growth rate 5,11 gram/day (3,1 gram/day). The slow growth rate of seeds stocked in November occurred because of crustaceans as the main feed of Barramundi in the early phase of the hatchery has a low abundance.
