“…A major difference between all these studies is the standard error (SE) associated with the heritability estimates. The low SE values obtained in our study (between 0.02 and 0.08) are slightly lower than those of Wang et al (2022), with an SE of about 0.11 using genomics on 764 individuals from random group matings of Hyriopsis cumingii, and in agreement with those obtained by , with an SE of 0.06. Conversely, we should not ignore the numbers of individuals and families (Houston et al, 2020).…”

“…GS has been investigated in the Portuguese oyster for morphometric traits, edibility traits and disease traits (Vu et al, 2021), in the American oyster for low salinity tolerance (McCarty et al, 2022) and in the silver-lip oyster for pearl quality traits (Jones et al, 2017). Genetic selection for growth traits has been studied in the triangle sail mussel (Wang et al, 2022), European flat oyster (Penaloza et al, 2022) and Pacific oyster . For the latter, GS to improve resistance to OsHV-1 has also been considered (Gutierrez et al, 2020).…”

“…In addition, complementary genetic studies to maximize egg and embryo viability and survival of veliger and juveniles are needed ( [96] and references therein). For example, genomic estimated breeding values established based on genome-wide single nucleotide polymorphisms and growth traits (i.e., shell length, height, width, and weight, and body weight), has imparted significant growth advantages to offspring of the commercially important freshwater triangle sail mussel, Hyriopsis cumingii [97]. Such knowledge of C. tritonis will promote the development of more reliable aquaculture methods to support stock enhancement and will be especially important should it prove an important conservation biocontrol agent against CoTS [98-101].…”

A Review of the Giant Triton (Charonia tritonis), from Exploitation to Coral Reef Protector?

2022

Charonia tritonis (Charoniidae), one of the largest marine gastropods and an echinoderm specialist, preys on Crown-of-Thorns starfish (CoTS), a recurring pest that continues to be a leading cause of coral mortality on Indo-Pacific reefs. Widespread historical exploitation has impacted their numbers, with standing populations considered rare throughout their habitat. Their life-stage attributes, i.e., teleplanic larvae, planktotrophic phase spanning years permitting transoceanic dispersal, and recruitment to coral reefs through oceanic influx with intense larval mortality, have likely hindered their recovery. Decline in numbers is hypothesised to account partially for periodic CoTS outbreaks, yet predator-prey dynamics between these two species that might influence this are poorly understood. The C. tritonis excretory secretome elicits a proximity deterrence effect on CoTS, the nature of which is under investigation as a possible tool in CoTS biocontrol scenarios. However, specificity and zone of impact in situ are unknown, and whether the mere presence of C. tritonis and/or predation pressure has any regulatory influence over CoTS populations remains to be established. The fundamental taxonomy and distinctive characteristics, biology and ecology of C. tritonis is summarized, and knowledge gaps relevant to understanding their role within coral reefs identified. Information is provided regarding exploitation of C. tritonis across its habitat, and prospects for conservation interventions, including captive rearing and stock enhancement to repopulate local regions, are discussed. Its predator-prey ecology is also examined and potential to mitigate CoTS considered. Recommendations to direct future research into this predator and for its inclusion in a CoTS integrated pest management strategy to improve coral reef health are offered.

“…Furthermore, genotyping-by-sequencing (GBS) has become a potential genome-wide genotyping tool that employs an enzyme-based complexity reduction method to simultaneously discover and genotype molecular markers across the entire genome, with or without a reference ( Elshire et al, 2011 ). The genome-wide SNPs discovered using the GBS technique have formed the basis of population structure and diversity studies ( Nyinondi et al, 2020 ; Yang et al, 2020 ; Fagbemi et al, 2021 ), linkage map construction ( Everett and Seeb, 2014 ; Uchino et al, 2018 ; Yin et al, 2020 ), QTL analyses ( Uchino et al, 2018 ), genome-wide association studies for economically important traits, such as disease resistance ( Correa et al, 2015 ; Gutierrez et al, 2015 ; Wang et al, 2017 ), and the application of genomic selection ( Wolc et al, 2015 ; Wang et al, 2019 ; Luo et al, 2021 ; Luo et al, 2022 ; Wang et al, 2022 ).…”

Labeo catla (catla) is the second most commercially important and widely cultured Indian major carp (IMC). It is indigenous to the Indo-Gangetic riverine system of India and the rivers of Bangladesh, Nepal, Myanmar, and Pakistan. Despite the availability of substantial genomic resources in this important species, detailed information on the genome-scale population structure using SNP markers is yet to be reported. In the present study, the identification of genome-wide single nucleotide polymorphisms (SNPs) and population genomics of catla was undertaken by re-sequencing six catla populations of riverine origin from distinct geographical regions. DNA isolated from 100 samples was used to perform genotyping-by-sequencing (GBS). A published catla genome with 95% genome coverage was used as the reference for mapping reads using BWA software. From a total of 472 million paired-end (150 × 2 bp) raw reads generated in this study, we identified 10,485 high-quality polymorphic SNPs using the STACKS pipeline. Expected heterozygosity (He) across the populations ranged from 0.162 to 0.20, whereas observed heterozygosity (Ho) ranged between 0.053 and 0.06. The nucleotide diversity (π) was the lowest (0.168) in the Ganga population. The within-population variation was found to be higher (95.32%) than the among-population (4.68%) variation. However, genetic differentiation was observed to be low to moderate, with Fst values ranging from 0.020 to 0.084, and the highest between Brahmani and Krishna populations. Bayesian and multivariate techniques were used to further evaluate the population structure and supposed ancestry in the studied populations using the structure and discriminant analysis of principal components (DAPC), respectively. Both analyses revealed the existence of two separate genomic clusters. The maximum number of private alleles was observed in the Ganga population. The findings of this study will contribute to a deeper understanding of the population structure and genetic diversity of wild populations of catla for future research in fish population genomics.
