6. Algae and Seaweed:
   Algae and seaweed serve as excellent sources of fiber and essential nutrients like Omega-3 fatty acids. Marine herbivores, such as tangs and parrotfish, thrive on these nutrients. A study by R. D. M. Beck et al. (2020) demonstrated that including algae in the diet enhances digestive health and nutrient absorption.

7. Specialized Diets for Specific Species:
   Specialized diets tailored to individual species can support unique nutritional requirements. Some fish may require higher protein content, while others may need more fiber. Research by H. A. Hu et al. (2021) revealed that species-specific diets improve growth rates and reproductive performance, demonstrating the importance of targeted nutrition.

In summary, enhancing marine fish nutrition involves utilizing a mix of high-quality feed, natural foods, and supplements tailored to the dietary needs and health of the specific fish species.
