Some Aspects of Reproduction in Amblypharyngodon mola from Sylhet, Northeast Bangladesh

The mola carplet, Amblypharyngodon mola (Hamilton, 1822) is the most common small indigenous freshwater fish species in Bangladesh. The precise information addressing the reproduction in this species including breeding peak, ovarian histology, morphometry, and sex ration in nature is still insufficient. A one yearlong filed survey and different laboratory assays have been directed to disclose some key features of reproduction in female A. mola from wetland reservoirs in the greater Sylhet region in Bangladesh. The total length and the body weight have shown a strong correlation with gonad weight, occupying statistical [r.sup.2] values of 0.89 and 0.91, respectively. However, a Chi-square test at P
