The correlation between sagitta otolith morphometry (length, weight, and breadth) and weight of Otolithoides pama (Hamilton, 1822) occurring in the Hooghly-Matlah estuary of West Bengal was examined for one year (February 2017 to January 2018). The sagitta otoliths were extracted, cleaned, photographed, and measured. Otolith length, weight, and breadth were recorded for each pair of sagittae. The length and weight of the fish sample, as well as those of otoliths, ranged from 51 to 327 mm, 1.1 to 270 g, 2.0 to 13.9 mm, and 0.0085 to 0.756 g, respectively. A linear relationship existed between the length and weight of otolith with the length of fish. The relationship between total fish length (TL) and otolith length (OL) was recorded as TL = 0.038 (OL) + 0.123 (R² = 0.799), that of total fish length (TL) and otolith weight (OW) being TL = 0.025 (OW) - 0.221 (R² = 0.887), that of total fish length (TL) and otolith breadth being TL = 0.031 (OB) + 0.089 (R² = 0.781). The morphometric relationships indicated that length, weight, and breadth of otolith exhibited a high correlation with the total length of fish.

印度Hooghly-Matlah河口的Otolithoides pama（汉密尔顿，1822年）耳石形态与鱼体大小的关系

研究了一年（2017年2月至2018年1月）发生在西孟加拉邦Hooghly-Matlah河口的矢状耳石形态（长度，重量和宽度）与Otolithoides pama（Hamilton，1822）的重量之间的相关性。提取，清洗，照相和测量矢状耳石。记录每对箭矢的耳石的长度，重量和宽度。鱼样品以及耳石的长度和重量分别为51至327毫米，1.1至270克，2.0至13.9毫米和0.0085至0.756克。耳石的长度和重量与鱼的长度之间存在线性关系。鱼总长（TL）和耳石长（OL）之间的关系记录为TL = 0.038（OL）+ 0.123（R ²= 0.799），总鱼长（TL）和耳石重量（OW）的TL = 0.025（OW）-0.221（R ² = 0.887），总鱼长（TL）和耳石宽度的TL = 0.031（ OB）+0.089（R ²＝ 0.781）。形态计量关系表明，耳石的长度，重量和宽度与鱼的总长度呈高度相关。
