Size frequency, length-weight relationships (LWRs), and length-length relationships (LLRs) for an estuarine fish Taenioides cirratus (Blyth, 1860) from the Noakhali coast, Bay of Bengal was studied. Specimens were caught with the fixed purse net of two mesh sizes (0.2 to 0.5 in. and 2.0 to 2.5 in.) from March to July 2019. The maximum total length for male T. cirratus (36.2 cm) reported in this study is a new record for this species. The length-weight relationships for male, female, and unsexed T. cirratus was highly significant (p < .001), and adjusted r² values were 0.967, 0.922 and 0.955 for males, females, and unsexed, respectively. The calculated growth coefficient (b) for male, female, and unsexed T. cirratus was 2.546, 2.948, and 2.618, respectively. The length-length eq. TL = 1.1974 SL + 0.4403 for the males and TL = 1.1712 SL + 0.7096 for the females were highly significant (p = 0.001, r² ≥ 0.978 for both males and females). Our estimated LWRs and LLRs parameters for male and female T. cirratus can be useful for the management and conservation purpose of this species.

研究了孟加拉湾Noakhali海岸的一条河口鱼类Taenioides cirratus（Blyth，1860）的大小频率，长度重量关系（LWR）和长度长度关系（LLR）。从2019年3月至7月，用两个网眼大小（0.2到0.5英寸和2.0到2.5英寸）的固定钱包网捕获标本。本研究报告的雄性西罗非鱼最大总长度（36.2厘米）为该物种的新纪录。雄性，雌性和未性别的T. cirratus的长度-重量关系高度显着（p  <.001），而雄性，雌性和未性别的调整后的r ²值分别为0.967、0.922和0.955。计算出的增长系数（b）为男性，女性，和去势T. cirratus为2.546，2.948，和2.618，分别。长度-长度eq。TL = 1.1974 SL + 0.4403的男性和TL = 1.1712 SL + 0.7096对于女性是高度显著（p  = 0.001，R ²  ≥0.978对男性和女性）。我们估计的雄性和雌性T. cirratus的LWR和LLRs参数可用于该物种的管理和保护目的。
