“…Comparisons of the deviations from HWE obtained in the present work with those of previous studies (Table 6) confirms that some wild populations and unselected stocks of tilapia conformed to the HWE (Romana-Eguia et al, 2004;Bezault et al, 2011;Sukmanomon et al, 2012), while departure from HWE equilibrium was detected in most of the farmed populations due to a significant deficit of heterozygotes. Deviation of the HWE in hatchery populations could be attributed to the aquaculture practices because a limited number of adults are spawned and an unequal sex ratio is applied (Napora-Rutkowski et al, 2017). The F IS values obtained in this study (0.031-0.121) indicate a deficit of observed heterozygotes.…”

Background: Tilapia is the most farmed fish in Colombia. However, the genetic diversity and structure of broodstocks in the hatcheries of Antioquia province remains unknown. Objective: To analyze the genetic diversity and structure of one Nile and three red tilapia broodstocks in Antioquia, Colombia. Methods: Fish were genotyped using 24 microsatellite markers of 13 linkage groups in five multiple reactions. Genetic diversity metrics were estimated and null alleles were detected. Analysis of Molecular Variance and analysis of number of clusters were used to describe the relationship between broodstocks. Results: Two microsatellites could not be amplified, and 22 were polymorphic. Average number of alleles per locus ranged 5.77 to 7.91. Locus UNH211 had the most alleles (17), whereas OMO032 had the fewest (4). Except for GM234 and OMO032, the analyzed loci had at least one private allele per population. Average effective number of alleles (3.37-4.03) was always less than the number of observed alleles. Significant deviations from Hardy-Weinberg equilibrium with heterozygote deficiencies were registered. Nine markers showed evidence of null alleles. The expected heterozygosity (0.65 to 0.67 per broodstock) was significantly higher than the observed heterozygosity (0.601 to 0.649) in the four populations. The fixation index for all broodstocks (excluding null alleles) was 0.0766 (95% confidence interval, 0.05092 to 0.10289). According to the molecular variance analysis, the greatest variation was between individuals rather than between groups of broodstocks or individuals within broodstocks. The genetic distance between the Nile and red broodstocks ranged from 0.43 to 0.54. Conclusions: Overall, these findings provide baseline information about the genetic diversity and structure of tilapia broodstocks in Antioquia, Colombia, useful for the management of hatcheries.

“…Genetic diversity was of great importance to the viability of populations (Qi et al, ) and widely accepted as an important component of population fitness (Napora‐Rutkowski et al, ). Nucleotide diversity was considered to be one of the major indicators of fish population genetic diversity because it represented the mean number of differences among all pairs of haplotypes (Wang et al, ).…”

“…The more effective population number was, the richer genetic diversity of its offspring was (Ward & Grewe, ). Low level of mtDNA polymorphism of carp in Europe was seemingly due to a bottleneck/founder effect at the early stages of domestication (Kohlmann & Kersten, ; Napora‐Rutkowski et al, ). Genetic variation within populations might be lost through genetic drift or a bottleneck effect (Billington & Hebert, ; Sun et al, ).…”

Fish of genus Erythroculter (Cypriniformes, Cyprinidae, Abramidinae) are important commercial freshwater species in China. In this work, morphological characters and gene sequences of mitochondrial CO I and Cyt b were analysed to investigate the germplasm differences among E. mongolicus, E. dabryi and E. ilishaeformis. Results demonstrated that about countable trait, there were six traits (scale in/ above/ below lateral line, gill‐raker in first left gill‐arch and branched fin‐ray in anal/ pectoral fin) showed significant differences. Gene fragments of CO I and Cyt b was 905 bps and 1,142 bps respectively. In CO I, there were 54.3% base content of A + T, 14 haplotypes and 84 nucleotide variable sites. As to Cyt b, there were 56.3% base content of A + T, 20 haplotypes and 142 nucleotide variable sites. In both CO I and Cyt b, the highest and lowest nucleotide diversity was detected in E. ilishaeformis and E. mongolicus respectively. According to morphological distance, genetic distance, genetic differentiation coefficient (Fst) and gene flow, E. dabryi was grouped together with E. ilishaeformis firstly, and then clustered with E. mongolicus. These results might be useful in the conservation and management of fishery resources of these three species.
