The addition of external carbohydrate in Pacific white shrimp (Litopenaeus vannamei) culture has shown positive effects on water quality and shrimp performance. However, this practice requires additional skills and labor, and therefore may not be widely adopted. This research investigated the potential to combine the carbon source and the feed in one pellet in shrimp culture. The carbon source used in this experiment was corn starch. The experiment was executed in 6 indoors mesocosms tanks, with full control of the water source, temperature, and light intensity and duration. The three treatments including COM-Feed (commercial feed), COM-Feed + CHO (commercial feed with separate corn starch addition), and CHO-Feed (pelleted diet made by incorporating additional corn starch into the commercial feed) were randomly assigned to the mesocosms tanks, and run two times consecutively. Adding corn starch separately resulted in higher shrimp biomass gain and protein efficiency ratio (P < 0.05), compared to dietary corn starch addition and no corn starch addition. Carbohydrate addition caused a significant drop in inorganic nitrogen and orthophosphate concentrations in the water. The treatments had no effect on the biofloc and periphyton growth, and the proximate composition of shrimp, biofloc, and periphyton, however increased the eukaryotic microbial diversity in the bioflocs. Meanwhile, the carbohydrate addition reduced the dietary energy and carbon utilization efficiencies regardless of the carbohydrate addition methods.

在太平洋白虾（南美白对虾）中添加外部碳水化合物）养殖对水质和虾的生长表现出积极的影响。但是，这种做法需要额外的技能和人工，因此可能不会被广泛采用。这项研究调查了在虾类养殖中将碳源和饲料结合成一个颗粒的潜力。本实验中使用的碳源是玉米淀粉。实验在6个室内中观空间水箱中进行，完全控制了水源，温度以及光强度和持续时间。将COM-Feed（商业饲料），COM-Feed + CHO（添加单独的玉米淀粉的商业饲料）和CHO-Feed（通过将额外的玉米淀粉掺入商业饲料中制成的颗粒饲料）这三种处理方法随机分配给饲料。中型坦克，并连续运行两次。 与饮食中添加玉米淀粉和不添加玉米淀粉相比，P <0.05）。碳水化合物的添加导致水中无机氮和正磷酸盐的浓度显着下降。这些处理对生物絮凝物和附生植物的生长没有影响，虾，生物絮凝物和附生植物的最近组成也没有影响，但是增加了生物絮凝物中的真核微生物多样性。同时，不管添加碳水化合物的方法如何，添加碳水化合物都降低了饮食能量和碳的利用效率。
