Acute Toxicity; Behavioural and Morphological alterations in Indian Carp; Labeo rohita H.; on exposure to Municipal Wastewater of Tung Dhab Drain; Punjab; India

Rajbir Kaur [2] | Anish Dua [2]


Abstract: Fingerlings of Labeo rohita were exposed to geometric concentrations (6.25 to 100 %) of municipal wastewater of Tung Dhab Drain; Amritsar; India.96h static non-renewal acute toxicity tests were conducted and simultaneously behavioural and morphological observations were noted. The 96h LC50 value along with 95 % confidence limits were found to be 44.25 % (38.47-50.92). The recorded values for chemical parameters such as TSS; BOD; NO3-N; O & G and heavy metals like Cr (VI) ; Mn; Pb and As were far more than standard discharge limits of effluents into inland surface waters. Fish in toxic media exhibited increased air gulping; surfacing; abnormal schooling; irregular; erratic and hyperactive swimming movements; hyper excitability; loss of equilibrium and showed vertical position prior to death. Morphological deformities included dark body colouration; excessive mucus secretion; loosening and loss of scales; haemorrhages on skin and fins; lateral flexure in caudal region and altered posturing of pectoral fins.
