Length-weight relationship and condition factors of congaturi halfbeak (Hyporhamphus limbatus) in the Kangsha river of Netrokona, Bangladesh

The Congaturi halfbeak, Hyporhamphus limbatus (Valenciennes, 1847) belonging to the family Hemiramphidae is a significant indigenous fish species in Bangladesh. This research work was carried out analyze monthly length-weight relationships (LWR) with construction of generalized body weight standard length measurements and condition H. for males females separately. A total 524 specimens (228 296 females) used this study were sampled from Kangsha River Netrokona, Bangladesh over year September 2020 August 2021. results revealed that highly correlated (r>0.730) limbatus. parameters equation W=aLb describing between male female varied monthly. LWR fitted pooled data all samples In case male, equations (a) 3.30 7.24 slope (b) 2.02 3.68. female, coefficient it ranged 4.2905 9.504 2.18 3.92. higher value regression co-efficient found either due maturation gonad or favorable feeding environment. males, growth both positive negative allometric. females, allometric except September, December, June July. Monthly relative factors based on CFBW values 1.0187 1.2070 lowest factor appeared October highest May 1.1117 1.4281, February 2021 April female. It has been as an index intensity be detected seasonal variation average storage population.
