Abstract

Correlation and Path Coefficient Analyses of the Morphological Characteristics and Body Weight of Penaeus monodon (Crustacea, Decapoda, Penaeidae)

The acute toxicity of glutaraldehyde, dibromohydantoin, methionine iodine and bleaching powder to juvenile Pinctada maxima was studied. The results showed that the order of toxicity was bleaching powder>dibromohydantoin>m ethionine iodine>glutaraldehyde and the median lethal concentrations (LC50) of above disinfectants were 13.05 mg/L, 27.49 mg/L, 53.20 mg/L and 67.36 mg/L, respectively in 24 h and the LC50 were 10.15 mg/L, 9.35 mg/L, 29.27 mg/L and 35.58 mg/L respectively in 48 h; and their SC (safe concentration) were 1.86 mg/L, 0.32 mg/L, 2.66 mg/L and 7.52 mg/L respectively. The research indicated that we can use glutaraldehyde to disinfect P. maxima under safe concentration, but should not use bleahing powder, and can use dibromohydantoin and methionine iodine carefully.
