Biocides, such as formaldehyde (HCHO), sodium hypochlorite (NaOCl) and glutaraldehyde(C5H8O2) that are commonly used in thermal, desalination and power plants and industries were testedon the commercially important mullet fish, Liza klunzingeri to determine the environmentalcontamination in the stressed ecosystem of Kuwait Bay sites. Multi-factor Probit analysis toxicity tests(96 h) on L. klunzingeri showed the lowest observed effective concentration (LOEC) and median lethalconcentration (LC50) with NaOCl (0.019 and 0.027 µg L 1 ) followed by HCHO (0.058 and 0.157µg L 1 ) and C5H8O2 (0.056 and 0.072 µg L 1 ). Site-wise analysis in the absence of feed showed highbiocides toxicity in L. klunzingeri reared in seawater from Site I when compared to Sites II-III.Experiments were conducted (2-9 months) by rearing fish separately in seawater collected from threeKuwait Bay sites to test the bio-accumulated toxicity levels at LOEC of biocides fed fish using FeedConversion Ratio (FCR) calculation. The lowest FCR was observed in fish fed with biocides in thesequence of NaOCl (0.40-1.1) followed by C5H8O2 (0.91-1.2) and HCHO (0.92-1.3) as well as withfish reared in seawater from Site I followed by Site II and Site III. High FCR was recorded in control(1.2-1.6) without the addition of biocides. These results exemplify the use of L. klunzingeri as anindicator species and may characterize a better quantification of biocides bioaccumulation using FCRcalculation in mullet fish. |
