I am considering incorporating a zinc supplement, commonly used as a growth promoter in humans, into fish feed to observe its effects on fish growth and health. Given the potential physiological differences between humans and fish, I aim to assess whether the zinc supplement can positively influence growth performance, immune function, or overall health in aquatic species. I will also evaluate potential risks, such as zinc toxicity or negative impacts on metabolic processes, by carefully monitoring dosage and fish response. This study could provide valuable insights into the viability of using zinc supplements in aquaculture.
