| 摘要: |
| 于1992年8－9月在山东乳山县海阳所镇虾场，使用复合口服免疫药物防治中国对虾病害，在现场观察对虾的发病情况、生长及增重速度；在实验室测定对虾血淋巴中的抗菌、溶菌活力和酚氧化酶活力。研究表明，对虾服用“口服免疫型”药物后具有明显的抗病防病能力及促生长等作用。 |

| Abstract: |
| An enlarged experiment on the above topic was carried in a prawn farm in Rushan County, Shandong Province, from August to September, 1992. The on-the-spot determination showed that prawn growth was accelerated while the incidence of diseases was decreased evidently after the immuno drags were taken orally. The ten-day increase of body length and weight of the experimental prawns was 0.77 cm and 3.6 grams/per prawn respectively, while that of the control were 0.53 cm and 3.0 grams/per prawn respectively.
Every 5 day laboratory measurement of the antibacterial, bacteriolytic and phenoloxidase activities in the haemolymph of prawn showed that the antibacterial activity (Ua) and bacteriolytic activity (UL) of the experimental prawns could be increased to as high as 0.74 and 0.462 (while that of the controls were only 0.30 and 0.13 respectively). The Ua and UL related to the strengthening or weakening of the immune function of prawn, and are quantitative measures of the effects of immune drugs.
All these proved that the immuno potency of prawn can be increased by immunological methods, and that the oral immuno drugs can be widely applied in prawn culture, to prevent and control the diseases of prawn and enhance their growth. |
