Abstract
This research aims to analyze several parameter dynamic populations of Bungo Fish in Lampopakka Lake, Wajo Regency. The research was done from August to October 2020. Fish samples were obtained from fishermen catching in Lampopakka lake and were analyzed in Fisheries Biology LaboratoryUniversitasHasanuddin, Makassar. Total samples were 837 individuals, male 639 individuals and females 198 individuals. Total length weight for male Bungo fish is 97-273 mm, divided into 3 age class: 124,8 mm, 178,92 mm and 230,72 mm.Total length weight for female Bungo fish is 100-246 mm, divided into 4 age class: 125,53 mm, 164,32 mm, 195,1 mm and 227,48 mm. Asymptote length (L∞-) for male fish = 284,5 mm with growth coefficient (K) = 0,15/year and t0 = -0,2123/year. Female fish^s (L∞-) = 258,5 mm with growth coefficient (K) = 0,46/ year and t0= -1,1524/year. Total mortality rate for male (Z) = 1,38/year and female 1,41/year, natural mortality (M) = 0,28/year for male and 0,59/year for female, catch mortality (F) for male = 1,10 and for female 0,82/year, exploitation (E) for male = 0,80 and 0,58 for female andYield per Recruitment Relativefoe male = 0,0426 and for female 0,0556. Conclusion Bungo fish in Lampopakka Lake are slow growth and suspected to have experience overfishing.
