摘要 1995年5 ̄11月,以人工合成饵料作为有机污染源,取体长8、10和12cm以上中国对虾,在0.9m^3水族箱中,分批进行有机污染提高对虾对病原体易感性试验。对虾在上述环境中培育2 ̄3周后,测定其对付溶血性弧菌易感性及体内与抗病有关一些酶的活性。结果:与对照组相比,试验组对虾对病原菌易感性提高1 ̄3倍;体内SOD、PO及溶菌酶活性分别下降约22%、50%和28% ̄86%。血细胞数量减少50%左右。 ──From May to November of 1 995,. P. chinensis were used experiments using excessive artifical di- ets as organic pollutants. Twenty about 8 , 10 or 1 2cm body length P. chinensis.. were put into the test pond and control pond. After 2~ 3 weeks , susceptibilities to pathogenic bacteria the number of haemocyte and lysozyme , SOD. PO activities were compared. The results were as follows. Susceptibilities to Vitrio para- haemolyticus , were 1~ 3 times that of the control pond shrimp (Table 1 ) , the haemocyte number of the test shrimps decreased about 50% , the SOD. PO and 1ysozyme activities of the test pond decreased a bout 22%, 50% and 28%~86% compared with those of the control pond (Table 2). Additionally it has been proved that in the test pond following the excessive artifical diets degreded , the DO content decreased , NH3-N increased markedly. So the conclusion could be drawn : organic pollution affects aquatic environment , decreases immune level , enhances susceptibilities to pathogen bacteria .
