It is critical to maintain continuity with dietary origin (commercial company) across generations and throughout development of a single generation. Generational continuity is essential to avoid unintended effects of nutrient imprinting and nutritional partitioning that can occur from consumption of different commercial diets due to their variable ingredient, macronutrient, and micronutrient profiles. For example, if consecutive generations consume feeds from two commercial sources and exhibit differences in, for example, growth or disease resistance, it would be impossible to determine whether these differences are attributes to diet or genetic selection. The research at the NCCCWA centers around the rainbow trout selective breeding program, therefore isolating and detecting effects of genetic selection is critical for research advancement. For this reason, maintaining diet continuity from past to future generations is essential for maintaining the integrity of this effort. Additional research focuses on understanding growth and reproductive physiology and immunological mechanisms. For these research efforts, future studies are designed based on findings from previous studies. Therefore, maintaining a consistent rearing environment, which includes the commercial diet, is essential for research continuity as it is well established that dietary variations affect growth rates, reproductive success, and the immune system.

Secondly, maintaining dietary continuity within a single generation enables fish to consume similar dietary formulations throughout their lifespan; this is critical as nutritional continuity, particularly regarding the types of protein and oils used, is important for maintaining digestive health and uninterrupted growth. Changing the commercial source of the diet will likely cause diarrhea and gut inflammation, leading to immunocompromised fish, poor feed conversion, reduce water quality, and interrupt growth trajectories which compromise fish welfare and the integrity of our research.

More than 50 peer-reviewed research articles published by scientists at the NCCCWA since 2005 have described the specific use of these commercial diets from Zeigler as part of the experimental design.
