Mmol/L to juvenile Japanese sea bass, and 75.86, 63.46, 56.42 mmol/L to black rockfish. When pH is steady at 8.40 + 0.10, the 24-, 48-, 96-hour LC50 of Alk are 72. 79, 65. 28, 57. 92 mmol/L to Japanese sea bass, and 69. 47, 59. 37, 51. 96mmol/L to black rockfish. It is obvious that the toxicity of Alk to fish increases with the progressive increase of Alk or time when pH is at a constant level.3. According to analysis of variance of orthogonal test, pH and Alk have signification effects on the mortality rate of black rockfish.
