摘要

我们分别研究了大使科Chanda nama (Hamilton, 1822)的广义长度-长度关系,研究了从孟加拉国Mymensingh的Old Brahmaputra河收集的一个日历年的雄性、雌性和组合种群。共检查了1170个标本,其中599个为雄性,571个为雌性。公蛙的标准长度为19 ~ 79 mm,叉长为23 ~ 90 mm,全长为28 ~ 100 mm。雌虫标准体长为15 ~ 81 mm,叉长为24 ~ 89 mm,全长为29 ~ 100 mm。标准长度与叉长、叉长与总长度、标准长度与总长度的广义关系分别为:FL = 1.08 SL+1.41、TL = 1.11 FL + 1.54、TL = 1.20 SL+2.81;FL = 1.09 SL+1.23, TL = 1.12 FL+1.04, TL = 1.22 SL+2.22;FL = 1.09 SL+1.20, TL = 1.11 FL+1.27, TL = 1.22 SL+2.38。决定系数(R2)在所有回归分析中均显示高值。在长度-长度关系中,决定系数(R2)为0.973 ~ 0.990。本研究结果将有助于对老布拉马普特拉河及其周边生态系统的昌达那玛渔业进行有组织和有意义的开发和管理。阿格利司》。,力所能及的。鱼类。8(3):339-347,2021年12月

Length-length relationships of elongate glass perchlet, Chanda nama (HAMILTON, 1822) from the old Brahmaputra river, Bangladesh
The generalized length-length relationships of Chanda nama ((Hamilton, 1822) belongs to Ambassidae were studied separately for a period of a calendar year collected from the Old Brahmaputra River, Mymensingh, Bangladesh for male, female and combined populations. A total of 1170 specimens were examined where 599 were male and 571 were female. The standard length, fork length and total length of male ranged from 19 to 79 mm, from 23 to 90 mm, and 28 to 100 mm respectively. The standard length, fork length and total length of female were found from 15 to 81 mm, 24 to 89 mm, and from 29 to 100 mm respectively. The generalized relationships of standard length and fork length, fork length and total length, and standard length and total length of male, female and combined populations were FL = 1.08 SL+1.41, TL = 1.11 FL + 1.54 and TL = 1.20 SL+2.81; FL = 1.09 SL+1.23, TL = 1.12 FL+1.04 and TL = 1.22 SL+2.22; and FL = 1.09 SL+1.20, TL = 1.11 FL+1.27 and TL = 1.22 SL+2.38 respectively. The coefficient of determination (R2) revealed high values in all regression analyses. In length–length relationships, the coefficient of determination (R2) ranged from 0.973-0.990. The present findings of this study will be helpful for a well-organized and significant exploitation and regulation of the Chanda nama fishery in the Old Brahmaputra River and surrounding ecosystems.
