混合营养体占浮游植物生物量的很大比例（有时高达80%）。绿藻是混合营养体的主要组成部分之一。混合营养型金藻由于其潜在的毒性和与高营养水平的微生物群落之间的联系，对潜在食草动物的影响受到广泛关注。本研究研究了不同比例的gloeopochromonas在饲料中（与斜花菜蛾混合）对中华水蚤生活史的影响。结果表明，在光照条件下渗透滋养生长的黄颡鱼会产生鱼类毒素和溶血素，并对黄颡鱼的生存和繁殖产生负面影响。随着食物中gloeopara的比例增加，枝海的死亡率也随之增加。当原色单胞菌占比超过35%时，中华拟南蝽终生不能繁殖。当饲料中含有15%的单胞菌时，中华绒螯蟹首孵时间延长，首孵子代数减少，总孵数减少。100%的斜棘虫替代延迟了水蚤的死亡时间，但没有提高水蚤的繁殖能力。本研究表明，黄颡鱼对中华拟南水北调有较强的抑制作用，并强调了评价其在水生生态系统中的生态作用的重要性。
Mixotrophs account for a high proportion (occasionally up to 80%) of the phytoplankton biomass. Chrysophyte is one major component of mixotrophs. Because of their possible toxicity and linkage between microbial community and higher trophic levels, the effect of mixotrophic golden algae on potential grazers received much attention. The present study investigated the effect of Ochromonas gloeopara at different proportions in diet (combined with Scenedesmus obliquus) on the life history of Daphnia similoides sinensis. Results showed that osmotrophically grown O. gloeopara in light produced fish toxins and hemolysins, and negatively influenced the survival and reproduction of D. similoides sinensis. The mortality of the cladoceran increased as the proportion of O. gloeopara in food increased. The D. similoides sinensis could not reproduce throughout the life when Ochromonas comprised above 35%. When fed foods containing 15% of Ochromonas, the time to first brood of D. similoides sinensis was prolonged, together with the reduced number of offspring in first brood and total number of broods. Replacement by 100% S. obliquus delayed the time to death, but did not improve the reproduction of Daphnia. The present study indicated the strong inhibitory effect of O. gloeopara on D. similoides sinensis, and underlined the importance of evaluating its ecological role in aquatic ecosystems.
