Vitamins and minerals are essential for maintaining the health and well-being of aquatic animals. They play crucial roles in immune function, bone health, and overall metabolic processes. Vitamins such as A, D, E, and the B vitamins are often added in the form of supplements or premixes to ensure adequate intake. Minerals like calcium, phosphorus, and magnesium are sourced from inorganic sources like limestone, bone meal, and rock phosphate.

In addition to these core ingredients, specialized additives may be included to address specific needs. For example, probiotics and prebiotics can be added to support gut health and improve feed utilization. Antioxidants, such as vitamin E and selenium, help protect fish from oxidative stress and improve the shelf life of the feed. Enzymes may also be incorporated to improve digestibility and nutrient absorption.

The Manufacturing Process: Step-by-Step - Ingredient Preparation and Mixing

In the fish food manufacturing process, the journey from raw ingredients to a finished product involves several meticulous steps, each critical to ensuring the nutritional quality and palatability of the final feed.
