“…Additionally, knowledge about length-frequency distribution (LFD) is essential to specify the recruitment pattern and mortality of a fish species in a particular aquatic ecosystem (Neuman and Allen 2001). Likewise, information on length-weight relationship (LWR) is indispensable for assessing the life history traits of a single species dwelling in varied geographic arena (Hossain et al 2013, Rahman et al 2020, Asadujjaman et al 2022. In order to estimate the biomass of a certain fish species, LWR data are frequently used (Khatun et al 2018).…”

The Indian river shad, Gudusia chapra, is a well-known species of potamodromous fish belonging to the Clupeidae family. The main focus of this study is to state the sex ratio, growth pattern, length-length relationship, form factor, Fulton’s condition factor and relative weight of G. chapra harvested from the Rupsha River (south-west Bangladesh). Altogether 300 specimens (male=166 and female=134) were harvested with the help of commercial fisher folks on seasonal basis (summer, rainy and winter) during 2022. Body weight and length of individual specimen were recorded with digital balance and measuring board. Total length varied between 12.7 to 16.5 cm for males and 13.0 to 17.3 cm for females. Further, body weight ranged between 15.82 to 42.48 g for male and 18.36 to 46.65 g for female. As a whole, both sexes revealed positive allometric growth pattern (b>3.00). Moreover, the length-length relationships were found highly correlated for both sexes. The estimated form factor was 0.0087 indicated fusiform body shape for G. chapra population. The mean Fulton’s condition factor was recorded close to 1 indicated a pleasant health condition for this species. Further, mean relative weight revealed a sound ecological atmosphere regarding prey-predator status. The research outcomes would be helpful to execute a sound management policy in the Rupsha River and connected ecosystem in the south-west Bangladesh.

Background Wild fish stocks continuously decline in Bangladeshi rivers and oxbow lakes. Small indigenous fish species management solely depends on their population status and conservation. This study aimed to determine the population status of Hyporhamphus limbatus, in Southwestern Bangladesh using conventional and truss morphological characteristics. Results A total of 174 fish samples were procured from monsoon season i.e., May to August 2018 the Bhairab River, BR; Kopotakkho River, KR; and Baluhar Baor, BB in Bangladesh. Five meristics, six conventional and twelve truss-based morphometric characters, were considered for stock identification. The Kruskal–Wallis test helped to analyze the meristic characters, while ANOVA, principal component analysis (PCA), discriminant function analysis (DFA), correct classification analysis using DFA, and a UPGMA dendrogram formation were used to investigate the conventional and truss measurements. By the Kruskal–Wallis test, no meristic characters showed significant differences across different populations. Eleven of the 18 morphometric measurements showed significant differences among three populations through the univariate ANOVA. PCA specified the population structure variations and explained 67.438% of the total variance. The first and second discrimination functions accounted for 78.3% and 21.7%, representing 100% of the group variability. Similarly, 85.6% of the grouped cases and 77.6% of cross-validated grouped cases were initially effectively represented by their correct number of individuals. A dendrogram based on morphometric (conventional and truss) displayed three stocks grouped into two clusters, with BR forming a distinct cluster, while KR and BB creating a shared cluster. Conclusion In conclusion, such morphological differences are most likely due to their distinctive ancestral origins. This study presents novel reports on the stock assessment of H. limbatus in their natural ecosystem. Furthermore, molecular research and an evaluation of the environmental impact on H. limbatus populations in Bangladesh are strongly recommended.
