The modified assay was linear up to 1500 mg/L of sulphate concentration, which is about 37.5 times more than that of conventional assay. Upon regression analysis, linear equation y = 1.243× + 0.011 was obtained having R2 value of 0.998. The modified assay was fully validated in terms of precision, limit of detection (LOD), limit of quantification (LOQ), sensitivity, selectivity and robustness to assure the reliability during final applications. LOD and LOQ were found as 7.4 mg/L and 24.8 mg/L of sulphate concentration respectively. Further, accuracy of the assay over routine SOB screening media components was tested, and proved as reliable and suitable for the intended application.Not Availabl

Not AvailableThe book provides meticulous, yet concise descriptions of viral, bacterial, fungal, parasitic and non-infectious diseases in an exhaustive number of fish and shrimp species. The book is designed as a comprehensive guide to the identification and treatment of both common and rare problems encountered in culture conditions. It is based on the methods currently followed by fish pathologists and laboratories and also includes early prevention, detection and treatment. The chapters cover essential information on the basic principles of disease causation, major diseases of cultured fish and shrimp, and standard operating procedures for prevention, control, diagnosis, treatment and quarantine. Health certification forms the key element of such control measures.Not Availabl
