Abstract

Abstract

From May to November of 1995,P.chinensis were used experiments using excessive artifical diets as organic pollutants.Twenty about 8, 10 or 12cm 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 parahaemolyticus, 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 lysozyme activities of the test pond decreased about 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.
- Penaeus chinenses,
- organic pollution,
- anti-disease ability,
- immune level
