Genetic variation of giant freshwater prawns Macrobrachium rosenbergii wild population of South Sulawesi, Indonesia

Abstract. Wahidah, Omar SBA, Trijuno DD, Nugroho E, Amrullah, Khatimah K. 2023. Genetic variation of giant freshwater prawns Macrobrachium rosenbergii wild population South Sulawesi, Indonesia. Biodiversitas 24: 3081-3090. Quality prawn broodstock can be provided using sources from populations with good morphological and genetic performance. This study aimed to analyze the genotypes in hence it used as basic information for quality broodstock. Evaluation haplotypes, rosenbergii, 3 rivers Sulawesi: 26 samples Waelawi River (11 males, 15 females); 25 Kalibone (10 Kariango (12 14 females), so there are 6 groups. Analysis mt-DNA obtained an amplification 700 bp. The amplified restriction uses four enzymes (Hae III, Mbo I, Rsa Taq I). identified male female each had haplotypes: 2 haplotypes; 1 haplotype; haplotype. Female highest haplotype diversity (0.3651), followed by (0.1449) (0.1011). females have farthest distance females. Waelawi, one cluster form a new Kariango, then Kalibone, last is formed Kariango. potential broodstock, which mated or other populations.
