鱼类废弃物是替代微藻的潜在低成本饲料来源，微藻是轮虫流行的食物。在不同饲料质量(即0.05、0.1、0.2和0.4g/L)、不同培养容器(小高(ST)、小短(SS)、中高(MT)和大短(LS)容器)、不同轮虫初始密度(10、50和200只/毫升)和大规模培养15天和30天的条件下，测定了轮虫的生长反应。饲料中添加0.05gr/L组轮虫种群密度显著高于添加0.05gr/L组(P<；0.05)。使用较大容器(LS和MT)的培养密度也显著高于使用较小容器(ST、SS)的密度(Tukey HSD检验，p<；0.05)，但在不同初始密度(ANOVA，p>；0.05)下接种时，差异不显著。轮虫经过30天的大规模培养，在2500~3300尾/毫升的密度下成功收获7次。
Fishwastes are potential low-cost diet sources for replacing microalgae, which is the popular diet for rotifers. Growth responses of rotifer were tested under different weights of the diet (ie 0.05, 0.1, 0.2 and 0.4 g/L), different culture containers (ie using small tall (ST), small-short (SS), medium-tall (MT) and large-short (LS) containers), different initial densities of the rotifer (ie 10, 50 and 200 rotifers/mL) and mass cultured trials for 15 and 30 days. Population densities of rotifers increased significantly (ANOVA, p= 0.001) when providing 0.1 to 0.4 gr/L than those fed 0.05 gr/L of the diet (Tukey HSD test, p< 0.05). The densities also were significantly higher (ANOVA, p= 0.001) when cultured using larger containers (LS and MT) than using smaller containers (ST, SS)(Tukey HSD test, p< 0.05), but it was not significant when inoculated at different initial densities (ANOVA, p> 0.05). The rotifers were successfully mass cultured for 30 days and were successfully harvested for 7 times at densities of about 2500 to 3300 ind./mL.
