“…However, to confirm this relationship, further association analysis studies between traits are necessary. Luo et al (2015), reported that selection in breeding program causes genes in populations to become homozygous; the affected genes are typically associated with a trait of fish species.…”

“…Number of studies have been using microsatellite markers to conduct genetic monitoring in selective breeding lines, such as Siniperca scherzeri (Luo et al, 2015), Ruditapes philippinarum (Yu et al, 2011), andPseudosciaena crocea (Hao et al, 2010). Nevertheless, few information about genetic structure of striped catfish populations thought breeding program.…”

Selective breeding to improve growth trait in striped catfish (Pangasianodon hypophthalmus) need genetic performance data. This study was carried out to evaluate genetic performance of different generations of the striped catfish population derived from selective breeding. Fifty fish of each population from four generations selected striped catfish was analyzed using five microsatellite loci (Pg-1, Pg-2, Pg-3, Pg-13, and Pg-14). Microsatellite allele data were analyzed using Microsoft Excel, Arlequin, and F stat software. A neighborhood joining dendrogram was constructed based on Nei's distance (Da) matrix with 1,000 bootstrap replications using MEGA7 software. The result showed that totally 31.5 exist, ranged from 4-7. Number of allele was ranged from 5.0 to 5.2, and polymorphic data was from 0.45-0.60. There were some exception, such as the allele of the loci Pg-2-194 bp, Pg-13-227 bp, Pg-13-229 bp, and Pg-14-279 bp; their gene frequencies were increased by generation. Further analyses indicated that most genetic variations arise from individuals within populations (approximately 57.10%). The founder generation closely related to G-0 generation. Likewise, G-1 generation closely related to G-2 generation. This result indicated that selection activity had a very significant impact on the genetic improvement of the selected population.

“…As time under selection increased, the genetic diversity tended to reduce, the differentiation between generations became less, and the variation of genetic structure of the populations became smaller. Luo et al (2015) studied the genetic diversity and structure of 5 consecutive selected populations of golden mandarin fish (Siniperca scherzeri Steindachner) with microsatellite markers and observed reduced genetic diversity over generations and there was increased genetic distance between adjacent generations. They opined that the generation populations of breeding had not fully adopted to the existing selection pressure and environment, and thus the population genetic structure had not yet stabilized.…”

Giant freshwater prawn, Macrobrachium rosenbergii is an important freshwater crustacean widely cultured in several countries including India. Of late, its production has come down due to slow growth rate and disease occurrences. The ICAR-Central Institute of Freshwater Aquaculture (ICAR-CIFA), Bhubaneswar in collaboration with the WorldFish, Malaysia has initiated a selective breeding programme for growth improvement of this species. In the present study, two groups of families (I. six numbers of families for growth and II. six numbers of families for disease resistance) were selected for experimentation from the families produced in the fourth generation of selection programme. Each group consisted of two extreme sub-groups of three families in each with higher and lower growth (based on weight) under group I and, susceptible and resistant families (based on larval survival following challenge with Vibrio harveyi) under group II. RAPD- PCR was used to evaluate the genetic variations between and within groups separately. Twelve selected decamer primers were used to amplify DNA fragments of three individuals of each family and data were analyzed by POPGENE version 1.31 software. In group I, a total of 102 bands were scored by the primers out of which 41 bands (40.19%) found to be polymorphic. Genetic diversity within the group varied from 0.0272  0.0965 to 0.0463  0.1316. UPGMA dendrogram of this group based on Nei’s genetic distance showed that families 5 (low growth family 2) and 6 (low growth family 3) are distantly related to high growth families. In the second group of disease resistance, 35 bands (36.46%) were found to be polymorphic out of 96 bands scored. Genetic diversity varied between 0.0301 ± 0.0957 to 0.0438 ± 0.1381 within this group. UPGMA dendrogram showed that families 1 (susceptible group 1) and 2 (susceptible group 2) are distantly related to three resistant families. Thus, the present results showed the existence of genetic variations in both growth and disease resistance traits that could be utilized in the selective breeding programme in M. rosenbergii.

“…Researchers have revealed that consecutive breeding for many generations has led to decreased genetic diversity in golden mandarin fish (Siniperca scherzeri Steindachner) as revealed by microsatellite markers 1. (Luo et al, 2015). Likewise, artificial selection is likely to have imposed distinctive signatures on Atlantic salmon (Salmo salar) characterized by reduction in genetic diversity and high genetic differentiation from other populations (Lopez et al, 2019).…”

Paddy field carp (PF-carp) is an economically important fish cocultured with rice in traditional agricultural systems. Several distinctive strains of PF-carp have been formed through years of artificial and cross breeding. There is a concern about the status of germplasm resources among PF-carp, since little is known about the genetic sources, diversity, or differentiation. In this study we collected 17 PF-carp populations covering Daotian carp (DTL), Ru Yuan No. 1 (RY), Jinbian carp (JBL), Shaijiang carp (SJL), and Wu carp (WL) along the Pearl River basin to explore their genetic sources and diversity using concatenated sequences of the mitochondrial cytochrome b gene and the D-Loop region. According to the haplotype network analyses, 1, 9, and 57 haplotypes originated from Cyprinus carpio carpio, Cyprinus carpio haematopterus and Cyprinus carpio rubrofuscus, respectively, confirming that genetic introgression has occurred in Pearl River PF-carp populations and Cyprinus carpio carpio was the most common species for genetic origin. The results showed that RY exhibited the lowest level of nucleotide diversity (π = 0.0011) due to high-intensity breeding and was significantly differentiated from the other four strains. PF-carp strains in these remote traditional systems tended to experience artificial selection and a lack of farmer connection that gradually increased genetic differentiation among strains. Notably, three populations of JBL exhibited significant high-level differentiation, since they originated from mountainous areas hindering farmers from fry exchange. In contrast, no significant differentiation was uncovered in the WL populations, since this strain is the most popular cultured strain and has undergone artificial exchange of parents and fry in many cultured regions. This study helps us to understand the status of germplasm resources among PF-carp and to trace their genetic origin before being introduced for local cultivation.
