초록
This study evaluated acute toxicity of chlorine dioxide (ClO2) to juveniles of black seabream Acanthopagrus schlegelii(19.4±2.3 g, 10.7±0.4 cm) and red seabream Pagrus major (74.9±8.2 g, 15.9±1.0 cm). Thirty juveniles for each specieswere exposed to target ClO2 concentrations of 0, 0.05, 0.1, 0.125, 0.15, 0.2, 0.3, 0.4, and 0.5 mg/L in triplicatefor eight days. Half lethal concentrations for 96 hours were found at 0.14 and 0.24 mg ClO2/L for black seabream andred seabream, respectively. Red seabream larger than black seabream in body weight appears to be more resistance tochlorine dioxide. However, regardless of species or size, specific loading rates of chlorine dioxide to total fish weight(daily feeding amount of ClO2 /total fish weight) were similar, showing 1.3 and 1.1 g ClO2/kg fishㆍday-1 for blackseabream and red seabream.
Abstract
This study evaluated acute toxicity of chlorine dioxide (ClO2) to juveniles of black seabream Acanthopagrus schlegelii(19.4±2.3 g, 10.7±0.4 cm) and red seabream Pagrus major (74.9±8.2 g, 15.9±1.0 cm). Thirty juveniles for each specieswere exposed to target ClO2 concentrations of 0, 0.05, 0.1, 0.125, 0.15, 0.2, 0.3, 0.4, and 0.5 mg/L in triplicatefor eight days. Half lethal concentrations for 96 hours were found at 0.14 and 0.24 mg ClO2/L for black seabream andred seabream, respectively. Red seabream larger than black seabream in body weight appears to be more resistance tochlorine dioxide.
