Morphometric characteristics and reproductive periodicity of fresh water fish, Lepidocephalus guntea (Hamilton)

A total of 600 specimens of Lopidocophalus guntea were collected from different fish landing centres of Rajshahi, Bangladesh during the period trom July 1994 to June 1995. After collection the fishes were preserved monthly in 59o formalin at separate jar and meristrics and morphometric characters were analysed. Five methods were used to determine the reproductive periodicity of L. guntea, mamely 1) percentage of gravid females against time, 2) gonado somatic index (GSI), 3) gonadal length index (GLI), 4) ova diameter and 5) colouration of gonad. The investigation showed that the breeding season of L. guntea starts from April and continue upto July.
