碩士 / 國立屏東科技大學 / 水產養殖系 / 93 / This research discusses the effect of total residual oxidant (TRO) on physiology and ecology of marine organisms. In the influence of ecology, the dominant biofouling species on PVC plates and concrete plates of recruitment at the inlet Kent-Ting 3rd Nuclear Power Plant adjacent water were barnacle, sea anemone and spirorbis, by 2-month intervals from November 2001 to July 2002. In addition, there was no difference on ecological index of different season. No difference of biofouling species abundance was found between PVC plates and concrete plates set. No significantly seasonal fluctuation of biofouling species abundance was found, except for barnacle and sea anemone. The settled densities are lowering deeper into the channel of the cooling system.
An experiment was conducted, under controlled temperature (26 ± 2 ℃) and salinity (33 ‰) to determine the acute toxicity of TRO to oyster Carassostrea gigas (length, 73.06 ± 12.28 mm); barnacle Balanus albicostatus (length, 8.12 ± 2.16 mm); Littoraria undulate (16.56 ± 2.55 mm); hard coral Stylophora pistillata (22.1 ± 0.6 mm); copepod Aprocydops royi (length, 1.03 ± 0.04 mm); fish and eggs larvae of grouper Epinephelus malabariacus; Silverside Hypoatherina tsurugae (length, 1.72 ± 1.48 mm) and black porgy Acanthopagrus schlegeli (weight, 137.41 ± 12 g; length,
14.39 ± 1.05 cm). The sub-lethal concentration (LC50) of TRO is 4.503, 1.696, 0.529, 2.290, 0.671, 0.544, 0.335, 0.158 and 0.175 ppm, respectively.
The black porgy exposed to TRO at 0.15 ppm for 6 hours revealed that its gill sections would cause clubbed lamellae, and exposed during 96-hr included lamellar fusion. In the physiology of black porgy, osmolality from 357 ± 8.3 increased to 399 ± 14.5 mOsmo/Kg, glucose from 56.3 ± 3.8 increased to 67 ± 7.5 mg/dl, Na+ from 171.7 ± 2.1 increased to 175.5 ± 1 mmol/L, K+ from 3.3 ± 0.1 decreased to 3.2 ± 0.4 mmol/L, and pH from 7.18 ± 0.16 increased to 7.34 ± 0.02, respectively. This study demonstrate that in the halide pollute could cause gill pathology change and influence on the index of blood physiology.
