In order to screen out the feeding ratio of high-quality algae strains in Hyriopsis cumingii, this experiment investigated the effects of different ratio of mixed feeding of two algae strains (Scenedesmus dimorphus and Cyclotella sp.) on the growth, bead production performance, trace elements, and amino acid composition of the newborn shell of H. cumingii. The results showed that the mixed feeding of two types of microalgae with different densities had significant effects on the growth performance, bead production quality, trace elements, and amino acid composition of the newly formed shell of H. cumingii (p < 0.05); the best body weight gain rate and shell growth rate were obtained by feeding S. dimorphus (30 × 10⁵ cell/mL) and Cyclopella sp.(8 × 10⁵ cell/mL); the pearl weight gain rate, amino acid ratio, Ca²⁺ and Mn²⁺ content were best when feeding Cyclotella sp. (16 × 10⁵ cell/mL), but there was no significant difference compared with S. dimorphus (30 × 10⁵ cell/mL) and Cyclopella sp.(8 × 10⁵ cell/mL). In summary, the optimal feeding amount for the intensive breeding process of H. cumingii is S. dimorphus (30 × 10⁵ cell/mL) and Cyclopella sp. (8 × 10⁵ cell/mL).

二形栅藻与小环藻不同比例混饲的效果。三角帆蚌新壳组织生长性能、产珠能力及生化成分的研究

为了筛选出三角帆蚌优质藻种的投喂比例，本试验考察了两种藻种（Scenedesmus dimorphus和Cyclotella sp.）不同比例混合投喂对三角帆蚌生长、产珠性能、微量元素的影响。三角帆蚌初生壳的元素和氨基酸组成。结果表明，不同密度的两种微藻混养对三角帆藻新形成壳的生长性能、产珠品质、微量元素和氨基酸组成有显着影响（p < 0.05 ）  ；饲喂双形鳅(30×10 ^{5 个}细胞/mL)和环藻(8×10 ^{5 个}细胞/mL)获得最佳增重率和壳生长率。饲喂小环藻时珍珠增重率、氨基酸比、Ca ²⁺、Mn ²⁺含量最佳。（16 × 10 ^{5 个细胞/mL），但与}S. dimorphus（30 × 10 ^{5 个}细胞/mL）和Cyclopella sp.（8 × 10 ^{5 个}细胞/mL）相比没有显着差异。综上所述，卡明氏菌集约化养殖过程中的最佳投喂量为S. dimorphus (30 × 10 ⁵ cell/mL)和Cyclopella sp.。（8 × 10 ⁵细胞/mL）。
