“…To prevent misclassification during analysis, a ratio of 3-3.5 between the minimum number of samples (N) and characters (P) are required (Kocovsky et al, 2009). Numerous investigations undertaken along this line have revealed comparable ratios, including 4.32 for Capoeta capoeta gracilis from the River Tajan, Iran (AnvariFar et al, 2011), 14.3 for Labeo rohita, India (Mir et al, 2013), 16.66 for Nandus nandus, Bangladesh (Mahfuj et al, 2020), 3.50 for Chanda nama, Bangladesh (Azad et al, 2020) and 14.30 for Cirrhinus mrigala in Ganges river from India (Dwivedi et al, 2019).…”

Wild fish populations are unceasingly diminishing in the rivers, ox‐bow lakes and floodplains in the Southwestern region of Bangladesh. Investigating the population status of vulnerable wild fish species are vital for the management and conservation of that species. This study aimed to identify the intra‐specific morphological variation and determine the population status of Lepidocephalichthys annandalei, in two rivers, the Nabaganga River in Jhenaidah (NRJ) and the Bhairab River in Jashore (BRJ) as well as a flood plain, the Dhakuria Beel in Jashore (DBJ) from Southwestern Bangladesh. Significant differences were observed in seven conventional and five truss‐based characters in univariate statistics. Conventional and truss‐network results from principal component analysis and CVA exhibited that populations were entirely intermixed, creating a compact cluster within intra‐population stages. Four principal components explained 51.93% of the variation in conventional morphometric characters and truss‐based characters. A UPGMA dendrogram was independently developed based on conventional and truss‐based morphometric characters. Among the individuals of NRJ and BRJ populations confirmed the presence of out‐group rather than the DBJ based on morphometric (conventional and truss) features. These notable isolations of populations of this species were supposed to be geographic disconnection and abiotic parameters. The evidence ensuing from the present study would be valuable for genetic studies as well as for in situ management.

“…To avoid inaccuracy during analysis, an N:P ratio of at least 3-3.5 is essential [55]. Various studies in this line found a parallel ratio of 4.32 in Capoeta, capoeta gracilis [56], 16.66 in Nandus nandus [57], 14.3 in Labeo rohita [58], 5.89 in Cirrhinus mrigala [59], 3.50 in Chanda nama [60].…”

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.

“…The previously mentioned specialist may have tested stocks that was encountering comparable ecological conditions or had a typical progenitor and consequently were not go through separation notwithstanding being secluded geologically. Notwithstanding morphometric characters, a truss network framework have been utilized by various researcher and has significant rule to recognize species, subspecies, races, and strains (Siddik et al, 2016;Ethin et al, 2019;Gain et al, 2017;Mahfuj et al, 2017;Azad et al, 2020;Mahfuj et al, 2020a).…”
