The effect of environmental factors on the population dynamics of brachionus calyciflorus 环境因子对萼花臂尾轮虫种群动态的影响
Effects of environmental factors on growth of brachionus plicatilis tipicus and brachionus plicatilis rotundiformis 型褶皱臂尾轮虫生长的影响
Acute toxic test of four heavy metal ions and their mixed solution on the brachionus urceus 4种重金属离子及其混合液对壶状臂尾轮虫的急性毒性试验
During the mysis substages there is a gradual transition from phytoplankton to zooplankton . feed on : diatoms , animalcule such as a . salina , oyster eggs and larvae as well as on rotifers and nematodes 1在糠虾期幼虫的蜕变中，渐渐从摄食植物浮游生物转变到动物浮游生物。饵料：藻类微生物如丰年虾牡蛎卵轮虫丝虫类动物。
During the period needed the proper growing environment , spread a mixture of amazerm and rice bran and yeast powder at the bottom of the pond and watch the living feed such as such as cop or class potif necessary for hatchery grow 在养殖池作水期间，将良益菌与米糠或酵母粉混合洒铺池底可培育出鱼虾苗所需之饵料生物如桡脚类,底栖生物多毛类轮虫等。
The morphology of resting eggs , factors influencing resting egg production , the hatch forms of resting eggs , factors influencing the hatch of resting eggs and the researches on resting eggs in natural ponds are discussed 重点介绍了轮虫休眠卵的形态、影响轮虫休眠卵形成的因素、轮虫休眠卵的萌发形式及影响其萌发的因素、自然水体中轮虫休眠卵的研究概况。
After molting three times , the zoea enter the mysis stage during which they begin to look more like adult shrimp and swim in a characteristic fashion with head and tail pointed downwards at right angles and occasionally performing a sudden retrograde jumping action . this is known as the inversion state , the fry being suspended upside - down in the upper middle region of the pond water . this is , therefore , also called the " inverted suspension phase " 眼幼虫脱第三次即进入糠虾期幼虫期mysis stage ，此期之体形已略成虾之状态，且具特有之游泳姿态，即头部及尾部均向下，成一直角弯曲而时作向后跳跃游动，又因成倒立状态，悬浮于水中的中上层，又叫倒吊期，此期幼虫对外界的环境因素，如水温盐分等变化，比前两期来得更具适应力，主要饵料为丰年虾brine shrimp的幼虫，但其他大小略同的动物性浮游生物，如桡脚类copepoda轮虫类rotifera均可。
Through the study of hydrolytic acidification - catalytic oxidation process treatment of wastewater of pulp anti paper making from waste paper and the microbes , what we found are as follows : it is certain that if there are more biaokeyuankechong in the water , the environment the water quality is worse : when swimming infusorian , eelworm , filamentous bacteria are found in the water , it shows the water is good : dark red alga and red pot ladybug show the water is still better , and higher microbes such as green alga and rotifer indicate the water quality is best 摘要通过对水解酸化接触氧化工艺处理废纸造纸废水及其生物相的研究，确定出表壳圆壳虫数量越多，环境和水质越差；而游泳类纤毛虫、线虫、丝状菌的出现是水质稍好的指示；暗红色藻类和红斑瓢体虫是水质更好的指示；而较高等生物绿藻和轮虫则是水质最好的指示。
Through feeding on varieties of food , it was found that paramecium sp . was one of the best feed for the initial feeding of takifugu obscurus larvae , and brachionus calyciflorus was fit for larvae stage , while the function of photosynthetic bacteria was to improve living environment 通过观察仔鱼形态发育特征和比较不同饵料饲喂仔鱼效果发现，草履虫为仔鱼期最佳开口饵料，轮虫为仔鱼期适口饵料，而光合细菌主要起调节水质的作用，和其它饵料搭配使用可取得较好效果。
