Data for effects of low fishmeal diets on growth performance, blood chemical composition, parasite resistance, and gene expression in the tiger pufferfish, Takifugu rubripes

The rising price of fishmeal and the need for sustainable use of fishery resources are encouraging efforts by the aquaculture industry to identify alternative protein sources. This is particularly the case for the tiger pufferfish, Takifugu rubripes, which is fed a high level of fishmeal as the protein source. In this study, we compared four possible replacement diets: in three diets, 37.5% of the fishmeal (30% of the total mass) was replaced by plant (PP), bacterial (BAC), or yeast (LY)-derived ingredients; in the fourth, 62.5% (50% of the total mass) was replaced by yeast (HY). Growth performance, blood chemistry, transcriptomic responses in the liver, and resistance to the parasite Heterobothrium okamotoi were compared in 360 cultured one-year-old tiger pufferfish. The raw data are shown in "Raw data Table 1-7.xlsx"鱼粉价格持续走高，加之渔业资源可持续利用的现实需求，正推动水产养殖业积极探寻替代蛋白质来源。这一趋势在虎河豚（Takifugu rubripes）的养殖中尤为显著——该物种目前以高鱼粉水平作为蛋白质饲料来源。本研究对比了四种替代饲料方案：其中三种饲料中，37.5%的鱼粉（占总质量的30%）分别由植物源（PP）、细菌源（BAC）或酵母源（LY）成分替代；第四种饲料中，62.5%的鱼粉（占总质量的50%）由酵母源（HY）成分替代。研究选取360尾养殖一周龄虎河豚，对其生长性能、血液生化指标、肝脏转录组响应以及抗寄生虫Heterobothrium okamotoi的能力进行了对比分析。原始数据详见"Raw data Table 1-7.xlsx"
