Fish meal is in trouble. Not as an ingredient — it remains one of the most nutritionally complete protein sources in aquafeed. The problem is supply. According to FAO data, approximately 16 million tons of wild-caught fish are used annually to produce fish meal — a volume that has been stagnant for decades while global aquaculture production has grown rapidly. The result: rising prices, tightening supply, and increasing pressure on wild fish stocks that the industry cannot su

Protein percentage tells formulators how much protein is present. Digestibility tells them how much of that protein the animal or person can actually use. For pet food nutritionists, aquaculture feed formulators, and R&D teams evaluating protein ingredients, digestibility is often the more important number — because a high-protein ingredient with poor digestibility delivers less usable nutrition per inclusion than a moderately lower-protein ingredient that is highly digestibl
