Abstract
Stressed ecosystem due to rapid industrialization installation of mega-desalination plants and suspected biocides glutaraldehyde: C5H8O2 formaldehyde: HCHO and sodium hypochlorite: NaOC1 discharges in the Kuwait marine environment instigated us to determine their toxicity on the body structures 1st dorsal fin eye lens otolith and scales of mullet fish Liza klunzingeri. 96 h toxicity test on biocides HCHO C5H8O2 and NaOC1 showed L. klunzingeri to be effective at test concentrations of 0.10 ug 1-1 0.07 ug 1-1 and 0.029 ug 1-1 respectively to produce LOEC lowest observed effective concentration. Observations showed high LC50 effect to fish with NaOC1 than HCHO and C5H8O2. Among the body structures high biocides concentration was observed in scales followed by 1st dorsal fin otolith and eye lens irrespective of the sampling sites. Bioaccumulation factor BAF in body structures was high in the sequence of HCHO C5H8O2 NaOC1 in Kuwait Bay than in the Coastal waters. These results characterize body structures of L. klunzingeri as a biocide indicator of pollution besides its use to validate age.
