dc.description.abstractHarpadon nehereus (Hamilton, 1822), commercially known as Bombay duck and is locally named as 'Bumla' or 'Bombil' along the western coast of India. The area between northern geographical coordinates of 18° and 22° N represents intermittent fishery resources with discontinuous distribution, and the majority of the resources are caught by the 'dol net'. The present study revealed information on 1523 specimens of Bombay duck, which were used for the analysis of length-weight relationship (LWR), and condition factor (K) collected from various fishing villages of west coast of India during September 2014 to November 2016. The results indicated that females bear longer and heavier body sizes than males. The analysis of LWR shows exponent 'b' values of 3.03 for males indicating isometric growth and female (3.10) establish growth as positive allometric (b > 3). A significant dissimilarity is observed in 'b' values among the seasons for Bombay duck (P < 0.05). The ‘b’ value was highest during summer (3.37), followed by winter (3.22), autumn (3.20), and monsoon season showed the lowest value, i.e., 2.95, indicating higher growth during the summer season in terms of weight. The Kn value observed in the present investigation was 1.02 ± 0.21. Information from the field for this species is rare, and the outcomes of the present study will help the administration in conservation of H. nehereus fishery in its natural range.en_US
