This study aims: (1) Knowing the model of surplus production that can be used (2) Knowing the optimum effort Sepat (3) Knowing the maximum sustainable yield (4) Knowing the utilization level of Sepat (5) Knowing the effort level of Sepat. The method that used in this research was survey method and collecting data. Data was analyzed by the Schaefer’s model and Fox’s model. The result of this research: (1) The best model is the Schaefer model with R2 and validation value (2) The catch rate of Sepat was 45630 trip per year (3) Maximum sustainable yield of Sepat was 45,466 ton per year. (4) The utilization rate of Sepat (Trichogaster sp) was 33% which shows there no more catch under fishing (5) Effort level of Sepat was 16 %. Keywords: fox model, maximum sustainable yield, schaefer model, sepat (trichogaster sp), surplus production model. 1. Introduction Fishing in the freshwaters in South Kalimantan are generally carried out in rivers, swamps, lakes and reservoirs. Fish that are usually caught are local fish. In 2012 the production of Sepat fish resources. Data on the level of fish utilization in water is very important because it determines the utilization of these resources is less than optimal, optimal, or even overfishing. Excessive use of fish will threaten the sustainability of the fish. Knowing the level of utilization of Sepat resources is expected to be carried out in a planned management. The Surplus Production Model is one of the simplest fish stock valuation models and is easily explained and accepted by fish resource managers. The basic assumption of this model is the entity's fish resources, without taking into account the actual processes that are not simple that causes the formation of the entity. Experts claim this model simplifies the process. This model only requires data capture and effort, these two types of data are usually known as fisheries characteristics. So, it is necessary to know the characteristics of fish resources, behavior and limits of the resilience of fish resources to fishing pressure (Badrudin, 2004). Formulation of the Problem: 1. What is the best surplus production model that can be used for catching Sepat (Trichogaster sp)? 2. What is the level of catching Sepat (Trichogaster sp)? 3. What is the maximum result catching of Sepat (Trichogaster sp)? 4. What is the utilization rate of Sepat (Trichogaster sp)? 5. What is the level effort of Sepat (Trichogaster sp)? Research purposes:
