Ascites syndromes disease is a common and ubiquitous disease in the industrial culture with turbot, which often results in turbot's massive mortalities. In June 2006, an outbreak of ascites syndromes disease of the cultured turbot Scophthalmus maximus occurred in an indoor farm in Shandong Province of China Through the isolation, purification as well as cultivation of the bacteria in the diseased fish, and by tracing the bacteria in the well water, rearing pond water along with the feeding trash fish, it was found that the bacterium RF-1 which existed in the trash fish was similar to the bacterium FS-1 in the diseased turbot; artificial infection test demonstrated that the bacteria RF-1 and FS-1 had the same infection symptoms for healthy turbots.
腹水病是工厂化养殖大菱鲆的一种常见病和多发病,常造成鱼类大规模的死亡。2006年6月山东某大菱鲆Scophthalmus maximus养殖场发生大规模腹水病,通过对病鱼细菌的分离、纯化和培养,对养殖井水、养殖池水和所用饵料小杂鱼进行细菌追踪调查,将从该养殖场所用小杂鱼中分离得到的细菌RF-1与鱼体分离的细菌FS-1进行比较,并对其进行人工感染试验,结果证明这2株菌对健康大菱鲆都具有很强的致病性,而且感染症状完全一致。

The results showed that: the influence of the aquaculture process on aquaculture water determined by type of aquaculture; the influence of aquaculture process on the water temperature, salinity and pH value were not wide.the descent of pH value was related to feed coefficients ; the dissolve oxygen of water in outfall was lower than the water in infall,but the concentration still maintained at the saturation level, is mainly affected by density of aquaculture ,rate of feed and artificial measures of increasing oxygen ;the major form of inorganic nitrogen was nitrate-N;the concentration of inorganic nitrogen and the organic matter tended to increase ,but the ammonium to decline ,this was relation with density of aquaculture ,rate of feed and variation of the different inorganic nitrogen form ; concentration of phosphate-P was low in outfall of pond , related with phosphate-P precipitating, as flowing water speed slowly in outfall;This phenomenon that the total number of bacteria and coli form group of water in outfall was lower than the water in infall , this caused by measures of sterilization and disinfection .
结果表明:养殖过程对水体影响与养殖类型有关。养殖过程对水体的水温、盐度和pH影响不大; pH下降与饲料系数高有关;溶解氧含量排水口比进水口低,但仍维持在饱和状态,与养殖密度、投饵率和人工增氧有关。硝酸氮是无机氮的主要存在形式,无机氮和有机物含量有升高趋势,氨氮有下降的趋势,与养殖密度,投饵率和各种无机氮之间的相互转换有关。活性磷酸盐含量在排水口含量下降,与排水口流水速度慢,磷酸盐沉淀有关。生物指标细菌总数和大肠杆菌总数在排水口比进水口低现象普遍存在,这与养殖场杀菌消毒等措施有关。

2Similar to other shrimps, artificial pond culture Penaeus monodon also had difference in growth between female and male. At early culture period, the difference between them was not distinct, but the female would grow more quickly than male after the fifty-ninth day. The body weight growth turning point of the male appeared at the 144.5 days, and at the 195. 3 days for the female.(3) By using Von Bertallanffy growth equation, the growth equations of Penaeus monodon were abtained.
