“…Morphometric stock assessments have embodied the evolution of morphometric analysis as an intricate discipline with applications in a wide range of biological disciplines. Morphometric assessment has also been used to identify unknown hybrids, unknown species, and population changes in aquatic organisms [26][27][28]. Morphological network observations indicate that they are made up of several digital landmark-based points and that they can be used to identify complex and familiar stocks [2,29].…”

Identifying stock is key to sustainable fisheries management and conservation. Using traditional morphometrics (TMR) and image-based truss network analysis (ITNA), we evaluated the stock structure of the endangered queen loach, Botia dario. The study was carried out in the following five stocks in Bangladesh’s northern rivers: the Atrai, Dhorala, Danu, Jamuna, and Padma. The inventory regarding stock structure was investigated using a total of nine traditional morphometrics, 11 ratios, and 23 truss measurements for each individual. To generate 23 ITNA, 12 landmarks were used. To assess variations among the stocks, a principal component analysis (PCA), factor analysis (FA), canonical variate analysis (CVA), and cluster analysis (CA) were performed. Six principal components explained 91.50% of the variation in TMR, while seven principal components explained 73.425% of the variation in ITNA. CVA, using traditional methods and ratios were correctly classified as 65.0%, 42.0%, 64.2%, 89.3%, and 77.5% for Danu, Padma, Jamuna, Dhorala, and Atrai River stocks, respectively, based on original grouped classes. CVA using ITNA was correctly classified as 90.0%, 80.0%, 77.4%, 94.6%, and 98.6% for Danu, Padma, Jamuna, Dhorala, and Atrai River stocks, respectively, based on original grouped classes. CVA analysis based on TMR and ITNA showed that cannonical variates (CV1 to CV3) are related to the whole-body shape. Both TMR and ITNA formed two clusters. In the first cluster, the Jamuna and Atrai River stocks combinedly formed a separate stock based on (TMR). In ITNA, the Dhorala and Atrai River formed as separate stocks from the other four stocks. According to this study, combining TMR and ITNA analysis aids in the differentiation of various B. dario stocks. The stock separation of this species was supposed to be geographic disconnection, waterway nature, and temperature variations. The B. dario stocks are heavily exploited and the species is an ideal nominee for species variation to boost the aquaculture yield. Within-stock distinctions were revealed in this study, necessitating the identification of gene pools and molecular studies to achieve a deeper understanding of the stocks. Through a more scientific approach, this stock structure study may aid in the development of conservation programs for this endangered species.

“…On the other hand, it is susceptible to salinity and water temperature. Cross‐breeding P. major ♀ (Pm) × A. schlegelii ♂ (As) has been shown to produce F1 hybrid progeny (AP) with the desirable parental characteristics (Bryden, Heath, & Heath, 2004), including a rapid growth rate, good muscle nutritional composition, and strong hypoxia and stress resistance (Jiang, Wu, & Shen, 2008; Jiang, 2011; Lin, Miao, Li, Yu, & Xu, 2014; Park, Kim, Lee, Hur, & Kim, 2006; Wang et al., 2016).…”

F1 hybrids may have heterosis in a wide range of traits, such as environmental adaptation or growth condition. To facilitate research on F1 hybrids of Acanthopagrus schlegelii ♂ × Pagrus major ♀, differentially expressed genes of the whole body transcriptome between F1 hybrids and parents were analysed using Illumina high‐throughput sequencing. The results showed that genes related to development and immune process had significantly expressed in F1 hybrids. It revealed that F1 hybrids had quick growth and strong resistance to disease versus A. schlegelii and P. major. This is the first report on the transcriptome of A. schlegelii, P. major and their F1 hybrids at 1 month of age and provides an important foundational data for studying molecular mechanisms of heterosis.

Background: Hybridization in two related homoploid species can mix the genotypes which have the potential for good environmental adaptation conditions or rapid growth condition. Since hybridization technique has been used in other animals to produce more rapidly growing individuals, it may be useful in commercial fish culture. The nutritional composition and rapid growth rate of P. major, A. schlegelii and hybrid F1 had been researched. However, gene expressions of these fish are less well studied. de novo assembly RNA-Seq is a better approach to understanding transcriptomes of animals and can offer much data with better coverage and sufficient sequence depth for transcriptomes. Results: In order to facilitate molecular research in parents and hybrids F1, we characterized the whole body transcriptome for identifcation of transcripts involved in growth, metabolism and immune since several attributes were coming from different samples (Acanthopagrus schlegelii, Pagrus major and hybrid F1 Acanthopagrus schlegelii ♂× Pagrus major ♀). We analyzed the transcriptome of As, Pm and hybrid F1 AP using Illumina high throughput sequencing platform. Our results suggested that physiological index of organism development we observed is consistent to the gene express in transcriptome. We have also compared the expression levels of transcripts in parents and hybrids F1. The results showed that AP had a quickly growth and strong resistant than parents Pm and As. Conclusion: This is the first research on transcriptome of As, Pm and hybrid F1 at one month age. And it will provide an important basic molecular data for studying molecular mechanisms involved in different sample.
