Size frequency, length-weight relationships (LWRs), length-length relationships (LLRs), and Fulton’s condition factor (Kn) were studied in an estuarine fish, <italic>Taenioides buchanani</italic> (Day), from Hatiya Island in the Meghna River estuary. Specimens were caught with fixed purse nets of two mesh sizes (0.51–1.27 cm and 5.08–6.35 cm) from February to April 2021. The maximum total length of female <italic>T. buchanani</italic> (37 cm) is a new record for this species. The length-weight relationships (LWRs) for male, female, and unsexed <italic>T. buchanani</italic> was highly significant (p&lt;0.001), and adjusted r2 values were 0.929, 0.931, and 0.955 for males, females, and unsexed, respectively. The calculated growth coefficients (b) for male, female, and unsexed <italic>T. buchanani</italic> were 3.087, 3.342, and 3.253, respectively. The length-length equations were TL = 1.1034 SL + 0.8845 (r2 = 0.977) for males and TL = 1.3728 SL + 0.9425 (r2 = 0.975) for females. There were no significant variations in Fulton’s condition factor among the specimens of different length classes (20–37 cm). To the best of our knowledge, no information regarding LWRs or length-length relationships (LLRs) for <italic>T. buchanani</italic> was previously reported either in the literature or on FishBase. The results from this study can be useful for management and conservation purposes of this mudskipper from the Hatiya Island.

Size frequency, length-weight relationships (LWRs), length-length relationships (LLRs), and Fulton’s condition factor (Kn) were studied in an estuarine fish, Taenioides buchanani (Day), from Hatiya Island in the Meghna River estuary. Specimens were caught with fixed purse nets of two mesh sizes (0.51–1.27 cm and 5.08–6.35 cm) from February to April 2021. The maximum total length of female T. buchanani (37 cm) is a new record for this species. The length-weight relationships (LWRs) for male, female, and unsexed T. buchanani was highly significant (p<0.001), and adjusted r2 values were 0.929, 0.931, and 0.955 for males, females, and unsexed, respectively. The calculated growth coefficients (b) for male, female, and unsexed T. buchanani were 3.087, 3.342, and 3.253, respectively. The length-length equations were TL = 1.1034 SL + 0.8845 (r2 = 0.977) for males and TL = 1.3728 SL + 0.9425 (r2 = 0.975) for females. There were no significant variations in Fulton’s condition factor among the specimens of different length classes (20–37 cm). To the best of our knowledge, no information regarding LWRs or length-length relationships (LLRs) for T. buchanani was previously reported either in the literature or on FishBase.
