Species association of Hilsa in the lower stretch of the River Ganges and their existing water quality

Abstract

Species association can be identified using data-mining technique. The species that can be catchable in single micro netting is considered as species association. This happens in nature by experimental netting. In all different combinations species associations of Hilsa ilisha are namely M. rosenbergii A. aor R. rita, E. vacha, R. corsula, G. guris, W. attu, L. rohita, L. bata, C. catla, C. mrigala, A. coila, C. garua, N.(Chitala) chitala, N. notopteru, P. paradisus, M. vittatus, P. saphore, P pama. The daring species may be associated even with major catfishes. As these species are found to be whether non harmful, associated and identified in the river stretch of Berhampore to Ulberia of lower stretch of river Ganges. Water quality database including assessment of available species in lower part of this stretch of river Ganges is carried out in this research study.
