Gill nets are used to catch fish samples for twelve months, from April 2019 to March 2020, at six sites in estuaries in the Mekong Delta. The analyses show that the weight of males and females of different fish sizes, seasons and sites are determined by a given total length since the determination coefficients of LWRs are high (r2>0 . 8 for all cases) . As the slope coefficient values (b) are higher than the threshold of three, both males and females display positive allometric growth patterns. Likewise, fishes caught at two fish sizes in two seasons and five sites (except in Vinh Hau, b=2.97±0.12 SE) exhibit positive allometry. The CF of Butis humeralis fluctuates around the well-being parameter of one, ranging from 0.95±0.01 SE to 1.08±0.02 SE, which indicates that these six sites are suitable environments for fish growth. The results yield reliable biological data for further research on manageable and conservable strategies of this species.  \nKey words: Butis humeralis, condition factor, length-weight relationship, positive allometry, Vietnam.  \nIntroduction  \nThe length-weight relationship of fish (LWR) has been studied since the 19th century, being a crucial tool for assessing and managing fish populations under various environmental factors (Martin‐Smith  \n1996, King 2013, Giarrizzo et al. 2015) . The LWR allows the estimation of the average weight fish from a known length group based on mathematical correlation and vice versa (Beyer 1987) . It helps to analyse the fish growth patterns, i.e. isometry or negative/positive allometry (Froese 2006) . The  \n*[Corresponding author: nguyenthanhnam@hus.edu.vn](Corresponding author: nguyenthanhnam@hus.edu.vn)  \nlength-weight data play a predictor role for the fish health (Le Cren 1951) .  \nButis humeralis (Valenciennes, 1837) is a species ofthe family Eleotridae (Thacker 2003) . In the Mekong Delta, this genus has three species: B. butis, B. humeralis and B. koilomatodon (Tran et al. 2013) . It is not difficult to separate Butis koilomatodon (sleeper goby) from other two congeners based on two ofits characters: five to six dark-brown bandson surface body and one band on caudal peduncle (Yokoo et al. 2006) and the serrated process on the snout (Contente et al. 2016) . Although B. butis has similar morphology to B. humeralis, it is relatively easy to differentiate these two species. Firstly, the head of B. butis is moderate-high, whereas B. humeral","cbCaimBpoaH4h4yj","https://ap.wps.com/l/cbCaimBpoaH4h4yj","pdf",907665,8,"English","# Abstract\n# Introduction\n# Materials and Methods\n## Study site\n## Fish collection","[{\"question\":\"What data were analyzed for Butis humeralis in this study?\",\"answer\":\"The study analyzed the length-weight relationship (LWR), growth patterns (including allometry type), and condition factor (CF) of Butis humeralis.\"},{\"question\":\"How were fish samples collected and over what time period?\",\"answer\":\"Fish were collected monthly using gill nets for twelve months, from April 2019 to March 2020, across six estuarine sites in the Mekong Delta.\"},{\"question\":\"What do the results indicate about growth pattern and habitat suitability?\",\"answer\":\"LWR slope coefficients higher than three show positive allometric growth for both males and females.
