Special Issue Information

Dear Colleagues,

Fishes, the most species-rich vertebrates in the animal kingdom, are valuable samples in studies on the historical and contemporary evolution of organisms. Climate changes, overfishing and habitat losses have led to rapid declines in fish populations and species. Studies on population genetics and conservation are vital to help us understand and reduce the risk of population and species extinctions. With the fast development of sequencing-based technologies, genome-wide molecular markers provide new insights into population genetics and conversation.

This Special Issue focuses on population genetics and conservation of fishes, including—but not limited to—identification of genomic signatures associated with population divergence, determination of the genetic basis of phenotypic traits possessed by different populations, processes on population over ecological time scales, linkage disequilibrium as expected for species with a large population size, adaption with selective sweeps and polygenic selection, etc.

This will be a dynamic Special Issue, and articles will be published as soon as the reviewers and editors are ready to accept them, without waiting for the deadline for the entire Special Issue to arrive.

The Chinese mitten crab (Eriocheir sinensis) is among the most important species in China and other countries, and it contributes significantly to aquaculture and meeting protein demands for the fast-growing human population. To ensure their sustainable exploitation, management, and use in aquaculture, it is imperative to know their genetic diversity. Thus, we studied the genetic diversity of six populations of Chinese mitten crabs from six different lakes in the Yangtze River’s drainage system. A total of 180 Chinese mittens crabs were collected from six lakes in China, with 30 being collected from each lake. Then, DNA was extracted using TaKaRa Dalian, genotyping was performed by the Gene Marker software for statistical analysis and the genetic parameters such as observed number of alleles (Na)were studied. A total of 87 alleles were observed in 180 individuals of six wild Eriocheir sinensis populations. The Fis results showed that six sites had negative values, and crab20 had the largest value. The results of Fit showed that the single locus had a negative value. All the Fst values among the populations were lower than 0.50, while an AMOVA analysis showed that 0.36% of the genetic variation came from among the six populations and 94.08% of the genetic variation was between individuals in a population. The six Chinese mitten crab populations showed higher genetic variability among individuals of the same population with very low genetic variability between the populations. Therefore, this illustrates that the crabs from the six lakes have similar genetic diversity and minor genetic differences among them. Full article

Background: The bullet tuna (Auxis rochei) is an epipelagic fish with a worldwide distribution that is highly targeted by fisheries. Genetic diversity and population genetics are good indicators of population structure and thus, essential tools for fisheries management. Knowing which factors (biotic and abiotic) might be shaping such structure is crucial for management plans. In the present study, we assessed the population structure of the bullet tuna in the western and central Mediterranean Sea. Methods: We used two types of genetic data: the mitochondrial DNA control region and seven microsatellite loci. The analysis of 431 sequences with a length of 386 bp from the mtDNA CR and the results from 276 individuals were genotyped by seven microsatellite loci. Results: Both types of markers coincided in showing significant genetic differences between an Iberian Peninsula–Strait of Gibraltar stock in comparison with a North African stock. Conclusions: We argue that this differentiation pattern is likely caused by reproductive strategies such as coastal spawning, larval retention, and natal homing behavior. These results should endorse the implementation of management plans for a resource that currently is not being managed. Thus, to ensure sustainability, these new policies should consider the presence of at least two genetically identified stocks. Full article

The Siamese fighting fish (Betta splendens) is a well-known ornamental fish and emerging model species for studying animal morphology, physiology, and behavior. A key concern of betta inbreeding is the decline in genetic diversity resulting from commercial breeding programs. Therefore, it is essential to develop markers for understanding the genetic bases of the domestication and phenotypic diversification of this species. We utilized the previously assembled genome of Siamese fighting fish to identify and characterize microsatellites and compare their genomic organization across different species. We annotated 812,134 microsatellite loci spanning 30.70 Mb, accounting for 6.57% of the Siamese fighting fish genome. We performed in silico polymorphism screening of microsatellites in the Siamese fighting fish and related species and present these sequences as candidate markers for cross-species amplification. In addition, we successfully validated two microsatellite loci using PCR-based assays in different species, which can promote further genetic characterization of diverse betta lineages. The set of polymorphic markers identified in this study may facilitate the assessment of genetic diversity and population structure and marker-assisted selection, among other applications.

In this study, a microsatellite-based multiplex PCR panel for meagre (Argyrosomus regius) was developed as a useful and single tool in parental assignment and population studies. Twenty-one specific and interspecific microsatellites from different aquaculture species of meagre (Argyrosomus regius), Japanese meagre (A. japonicus), red drum (Sciaenops ocellatus) and yellow meagre (Acoupa weakfish) were assessed for genetic variability, allelic range and genotype reliability. Finally, a SuperMultiplex for Argyrosomus regius (SMAr) was designed with only the best eight microsatellite markers. The panel assessment was performed using a batch of brood stock from one company and a sample of 616 offspring. It was possible to assign 95% of the offspring to a single pair of parents using the exclusion method. It is therefore considered an easy procedure, and a powerful and low-cost tool for parental assignment to support companies’ breeding programs and to exchange information between research groups.
