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.
