Length-weight relationship and condition factor of captive raised moustached Danio, Danio dangila (Hamilton, 1822)

Abstract

Danio dangila (Hamilton, 1822), common English name Moustached Danio [9, 10] as it has two pairs of extended barbels on its top lip, one pair being particularly long. It is an important ornamental danid found in north eastern states of India. Length-weight Relationship and condition factor was estimated from captive raised fish ranges from 2.9cm-8.8 cm and weight ranged from 0.18gm-9.4gm. The analysed L-W data showed the ‘b’ value is 3.18 which indicate its positive allometric growth. The ‘K’ value is 1.18 indicating robustness or well-being of fishes.
