<![CDATA[The province of Lampung is one that utilizes fish resources of up to 380,000 tons per year of the total fish stocks landed in existing fishing ports. One of them is the Lempasing Fishing Port Beach (PPP), which has a strategic location and directly borders the Gulf of Lampung. However, according to the annual report of PPP Lempasing from 2013 to 2022, landed catches tend to decrease every year. Therefore, it is necessary to make maximum use of fish resources. In this study, fish stocks were analyzed using the surplus production approach using the equilibrium state method, the Schaefer 1954 model, and the Fox 1970 model, and then the non-equilibrium state model, the Walter-Hilborn 1976 model, in one and two ways. From the results of the analysis it was found that the correct model for determining the level of utilization and catch status used the Walter-Hilborn model of the second way which has the second highest R2 value which reaches 80% and for the highest value of R2 obtained the model Walter- Hilbron one way reaches 95% but with the utilization rate of 313% this is less relevant because it does not correspond to the facts on the field, in this case the utilizing rate in PPP Lempasing according to the Walter -Hilborne model of second way reached 97% which means fully exploited recommended in utilizing the fish resources can refer to the value (YMSY) 713 tons/year, maximum catch effort (FMSY), of 1240 tons/ year, with the number of allowed catches (YJTB) of 571 trips/year in which each trip (UMSY) can catch as much as 0.58 catches. In this case, too, the catch effort can be increased, but by considering the value of the sustainable stock or fish stocks that exist at the depth of Be 727 tons]]>
