4. Physiological Growth Response of African Catfish to a Diet with Black Soldier Fly Meal

This study revealed that replacing fishmeal with black soldier fly meal did not negatively affect production performance and metabolic response in African catfish farming. On the other hand, replacement with mealworm meal may lead to reduced fish growth and health problems.

Marine Living Resources

5. System and Method for Cultivating and Harvesting Floating Seaweed and Aquatic Plants

The floating cultivation system for seaweed and aquatic plants includes an enclosed area positioned in a body of water. The enclosed area is defined by one or more floating barriers, each including an attached mesh skirt. The one or more floating barriers are fixed in a location in the body of water with an anchoring system or foundations.
