Overview

Genetic analysis reveals moderate to high genetic diversity across six breeding populations of giant freshwater prawns, suggesting strong potential for future selective breeding programs.

Key Points

Evaluate the genetic diversity and population structure across six selective breeding stocks of giant freshwater prawn (Macrobrachium rosenbergii) to inform broodstock management.
Evaluated six selective breeding populations in China (HF, NTH, JX, SF, TW, and GX) using 16 newly developed microsatellite markers.
Sequenced the mitochondrial control region (D-loop) to assess genetic differentiation and diversity metrics across populations.
Microsatellite markers showed polymorphism information content (PIC) > 0.5 across all loci, with expected heterozygosity ranging from 0.83 (GX) to 0.89 (SF) and pairwise Fst values from 0.03541 to 0.09637 (p < 0.05).
Mitochondrial D-loop analysis identified 114 variable sites and 29 haplotypes, yielding a mean haplotype diversity of 0.640, nucleotide diversity of 0.01247, and pairwise Fst values of 0.05603–0.80788 (p < 0.05).
