What is it about?
This study explores using enzymes from shrimp processing waste (hepatopancreas) to improve tilapia feed. Aquaculture needs better ways to digest proteins and reduce environmental impact. We extracted, purified, and then put these powerful digestive enzymes into tiny, protective capsules made of sodium alginate. Our tests showed these encapsulated enzymes work best at 40°C and pH 9, conditions similar to a fish's gut. The capsules released the enzymes steadily, and their activity remained strong for over two weeks. This research offers a promising, sustainable way to turn shrimp waste into a valuable feed additive, making aquaculture more efficient and environmentally friendly by boosting nutrient use.

Why is it important?
This research offers a sustainable solution for aquaculture by turning shrimp waste into effective feed additives. It improves fish digestion, reduces costs, and promotes a circular economy.
Perspectives
Our study shows encapsulated enzymes from shrimp waste can boost tilapia feed digestion. This makes aquaculture sustainable and more efficient by using waste, improving fish growth, and reducing environmental impact.
