Koi fish is one of the species included in the intensification program of ornamental fish production. Production of koi has only reached 82.04% of total national production target thus making it potential for development. The objective of the study was to assess additional financial benefit of production increment through stocking pattern modification. Present research was performed using case study method on "Pokdakan PBC Fish Farm (PPFF)", koi fish farmers in Sukabumi. Financial analysis consisted of business analysis, investment criteria, and sensitivity. Stocking pattern management could increase ornamental fish production and its benefit margin up to 1.5 times higher. That investment criteria has shown net present value (NPV) at value of Rp3,824 million, net B/C ratio 4.96, internal rate of return (IRR) 86.0%, and payback period (PP) 1.7 years. Koi fish farming was sensitive to a decline in survival rate and insensitive to the rise of formulated feed price.Keywords: business analysis, koi, investment criteria, stocking pattern, production ABSTRAKIkan koi merupakan salah satu ikan yang termasuk dalam program penguatan produksi ikan hias Indonesia.
