Description Fishery of Cistopus indicus by trawlers at New Ferry Wharf from 2000 to 2009 in Mumbai waters is
described. The catch showed an increasing trend up to 2006 and declined thereafter. The catch ranged
from 2 t (2002) to 324 t (2006) and the catch rate from 0.002 kg/hr (2002) to 0.181 kg/hr (2006). The
relationship between dorsal mantle length (DML) and total body weight (TBW) for males was TBW =
0.001053 * DML2.69321 and for females was TBW = 0.009 * DML2.19221. Fish formed the major food item
of both the sexes. Majority of the males in the landings was in mature stage, while the maximum number
of females was gravid. The size (DML) at 50% maturity for females was estimated as 82.7 mm. The
diameter of mature ova ranged from 2 to 6 mm and fecundity was 13,260
