AB  - The genetic variation of wild and hatchery populations of 
  rohu individuals was analyzed using allozyme marker. The fish samples were collected 
  from 3 main wilds (Halda, Jamuna and Padma) and 6 hatcheries of 3 origin (Brahmaputra 
  and Rahim fish hatchery, Mymensingh; Rupali and Ma-fatema fish hatchery, Jessore; 
  Bismillah and Rupali fish hatchery, Comilla) covering a wide geographical distribution 
  of this species. The 6 enzymes (LDH, MDH, PGM, AAT, ADH GPI and G3PDH) encoded 
  by 7 presumptive loci were screened and 4 (Mdh-1*, Gpi-1*, Gpi-2* and Pgm*) 
  were found to be polymorphic which were interpretable in muscle with starch 
  gel electrophoresis. The mean proportion of polymorphic loci, the mean proportion 
  of heterozygous loci per individual, the average observed Heterozygosity (H<SUB>o</SUB>) 
  and expected Heterozygosity (H<SUB>e</SUB>) were 42.85, 15.77, 0.125 and 0.184%, 
  respectively for wild populations which were higher than the hatchery populations 
  (33.33, 12.20, 0.075 and 0.094%, respectively). The highest gene flow value 
  (26.725) and lowest population differentiation (0.009) found in the Halda and 
  the Jamuna River populations indicate the close relationship among them Based 
  on Nei (1972)&#146;s UPGMA dendrogram, 
  9 populations of rohu were divided into 2 major clusters by the genetic distance 
  of D = 0.092. The cluster-1 consisted of 3 wild populations and the cluster-2 
  consisted of 6 hatchery populations. The present study revealed that the considerable 
  genetic variation is maintained among the wild and hatchery populations of rohu.
