Sustainable marine fisheries resources exploitation requires a utilization rate lower than their availability. Therefore, the exploitation rate should not achieve the recovery ability of the resources in certain time. In fishing activities, for instance, there is a guideline not to catch fish over the Total Allowable Catch (TAC), 80% of the MSY. Information on the potency and the fishing capacity of tuna fisheries can be useful for the sustainable management of the resources. Also, this information can be used as a consideration for further management of the potency. There are two purposes of the study: (1) to analyze the CPUE (catch per unit effort) of demersal fisheries in Kema 2, North Sulawesi, for prediction of their potency, and (2) to analyze the efficiency of fishing capacity of the demersal fisheries in Kema 2, The study was done in two stages. The first was done by analyzing the potency using CPUE method (Shaefer models) to obtain the MSY, optimum effort and TAC (total allowable catch); and the second was done by analyzing the fishing capacity of demersal fisheries using DEA method to estimate the efficiency level of the fishing boats and devices in Kema 2. The result showed that the potency of demersal fisheries in Kema 2 was 71,700 tons per year and the optimum effort was 72,964 trips. Fishing capacity in demersal fisheries occurred in Kema 2 for the last 12 years was inefficient, especially for 2001. This may be caused by some factors such as trip operation, fishing duration, oil consumption, crew and operational cost. So, to manage the demersal resources in Kema 2, the TAC should be 57,520 tons per year. Based on the result, to increase the fishing efficiency, we should take into account of above factors. We suppose that the good means is reducing trip operation, fishing duration, oil consumption, crew and operational cost. Keywords— CPUE, MSY, TAC, Fishing Capacity, Kema 2 I. INTRODUCTION Capture fisheries is an economic activity that has high contributions to the production of marine fisheries in North Sulawesi Province. Kema 2 is a part of North Sulawesi Province geographically located at N 1°23'23" - 1°35'39" and E 125°1'43" - 125°18'13". Demersal fish is one of the fisheries commodities in Kem 2 having economic value. It can be exported as fresh fish several countries. Since demersal fish has become an export commodity, fishing activities of the local fishermen is increasing. Nevertheless, there is no information on the potency of demersal resources. Control on fishing effort is one of the approaches to manage the fisheries resources relating to restrictions on the fishing capacity or the amount of fishing gears. The goal is to increase catches and fishing industry's economic performances through reduced effort or excessive fishing capacity. The issue of managing fishing capacity has developed along with the developing attention to the phenomenon of the excess spread in fishing inputs and
