碩士 / 國立臺灣海洋大學 / 環境生物與漁業科學學系 / 93 / This thesis tries to find out the influence of copper heavy metal on Freshwater shrimp (Neocaridina denticulata) in acute toxicity, oxygen consumption rate and ammonia excretion rate.
Experiment of acute toxicity used seven kinds of concentration of copper -- 0.01、0.02、0.04、0.08、0.16、0.24、0.32 ppm. Experiment of oxygen consumption and ammonia excretion used four kinds of concentration of copper -- 0、0.01、0.02、0.04 ppm. The experimental soaking time of acute toxicity, oxygen consumption and ammonia excretion spent 96, 24 and 24 hours, respectively.
Results of acute toxicity lead to a logistic formula of Freshwater shrimp lethal curve from each copper concentration. From this formula, we can get the Freshwater shrimp death rate from each concentration of copper within 0.01~0.32 ppm. Besides, results show that the 96hr-LC50 is 9.23 ug/L.
The rate of oxygen consumption of Freshwater shrimp increased with the increasing of copper concentration in the same exposed time, while the rate of ammonia excretion of Freshwater shrimp decreased with the increasing of copper concentration in the same exposed time.
Averagely, oxygen consumption rates of Freshwater shrimps, exposed 24 hours in the 0, 0.01, 0.02, 0.04 ppm concentration of copper water, are 0.68, 1.047, 1.042, 0.97 mg/g/hr respectively, as well as, ammonia excretion rates of Freshwater shrimps are 0.1353、0.0709、0.0495、0.0492 μg/g/hr respectively.
Key words: Freshwater shrimp (Neocaridina denticulate), Copper heavy metal, Acute toxicity, oxygen consumption rate, ammonia excretion rate.
