The aim of this study was to evaluate the attach rate and survival rate for the female harpacticoid Tigriopus japonicus response to 4-nonylphenol, known endocrine disrupter. The organisms were sampled by net sweeping on the Jeju Island in April, 2004 were reared in the laboratory condition. As the concentrations increased, the mortality was slowly increased. The first day for appearing dead individuals was clearly different between control conditions and treated conditions. When the female with egg sac was moved to experimental conditions for the adaptation, the female was dropped the egg sac from the body and then reproduced the egg sac into four to five days. Usually the female in control group recovered egg sac but that in the treated group made egg sac between $89%;and;95%$ on exposed individuals. The dead individuals for control conditions were showed on ten days after treating chemicals while those for treated conditions were appeared four to six day after exposure to chemicals. |
