Abstract
Common Ponyfish is the dominant fish in the Awangpone Waters, exploited throughout the year so it is feared that its population will decline. This study aims to analyze aspects of populist dynamics including age group, population growth, mortality, exploitation rate, yield per recruitment. Data on the total length of fish is collected through measurement of catches from February, March 2023. Age groups were analyzed using the Battacharya method, L∞- and K allegedly using the Ford and Walford methods, the Pauly Empirical M method, Z, F and E the Beverton and Holt methods. Data processing with FISAT-II and Microsoft Excel software. The results of the study that common ponyfish have a total length range of 4 to17.6 cm, the size of the most catches is in the middle of the class of 10 to12 cm and an average length of 13.06 to 2.15 cm. The population consists of one age group, the presumptive values L: 20 cm, K:1 per year and t0: -0.17777 years. Conjectures Z, M and F amounted to 4.32 per year, 2.06 per year and 2.27 per year, respectively. The exploitation rate was 0.52 per year and the actual, optimal Y/R were 0.0205 gr/recruitment and 0.0203 gr/recruitment, respectively.
