The following proofs of Goldfish more powerful reproductive potential are given: high individual and relative fecundity, adequate fractional spawning process resulting in numerous off spring, represented by different generations of hatchlings, little number of individuals not participating in reproduction, prevailing number of fish eggs in females’ ovaries, larger fraction of impregnated roe. All the above mentioned factors allow claiming that the Prussian carp is being replaced due to its low replacement ability. Perhaps for that reason Carassius gibelio (Bloch, 1782) choose small isolated water bodies, where it makes small populations, backed up by successful spawning with a single male of crucian carp, Carassius carassius (Linnaeus, 1758).

Genetic structure of golden grey mullet Chelon auratus investigated in the Fereydoon-Kenar and Ramsar coasts (south Caspian Sea, Iran), using 6 microsatellite markers designed for gray mullet (Mugil cephalus) and hand mullet (Liza haematocheila). A total of 60 samples of adult C. auratus were collected from these regions. All primer sets as polymorphic loci were used to analyze genetic variation. Analyses revealed that average of alleles (Na) per locus was 6.2 (range 3 to 9 alleles). All sampled regions contained private alleles. The average estimates of inbreeding coefficient (Fis) values of 6 microsatellites were positive. The average observed and expected heterozygosity was 0.394 and 0.743, respectively. Deviations from Hardy-Weinberg equilibrium were in all cases (P<0.001). F-statistics (Fst) and gene flow (Nm) estimates in allele frequencies were 0.078 and 2.9, respectively. Fst estimates in AMOVA indicated significant genetic differentiation among regions (P<0.01). Genetic distance was 0.679 indicating that the genetic difference among the studied populations is pronounced. The data generated in this study provides genetic variation and differentiation in populations of C. auratus in the southern Caspian Sea.
