Shrimp Nutrition: what is the protein requirement at each stage?

Shrimp farming, often referred to as aquaculture, has been expanding rapidly as a profitable and economically significant sector. However, this growth brings concerns about shrimp health and the standards of cultivation. As shrimp farming continues to evolve, ensuring optimal nutrition becomes paramount to maximize growth, improve health, and guarantee survival throughout all stages of their development. In this context, balanced nutrition is critical for shrimp health and productivity. Protein, being a vital component of their diet, plays a key role in muscle synthesis, cellular regeneration, and overall metabolic performance. According to the Food and Agriculture Organization (FAO), shrimp typically require a protein intake ranging from 30 to 55% of their total diet, depending on their developmental stage and environmental conditions. This highlights the necessity for precise dietary adjustments at each stage to support growth while minimizing nutrient wastage. This article aims to explore the protein requirements of shrimp at different developmental stages. Understanding these needs is essential for farmers to optimize feeding strategies and enhance production efficiency. One of the most critical stages is the post-larval phase, which spans the first 10 to 20 days after hatching. During this period, shrimp require a high-protein diet, ideally between 40 to 55%, to facilitate rapid growth and cell differentiation. High-digestibility ingredients, particularly those rich in bioactive peptides, are crucial for effective digestion and enhanced immune function. Deficiencies in protein at this stage can severely impact growth and survival, affecting the efficiency of subsequent phases. Moving into the juvenile stage, which lasts from 25 to 35 days, the protein requirement drops slightly to approximately 35 to 40%. Here, protein not only supports growth but also plays an immunological role, strengthening the juvenile shrimp’s resilience against pathogens. A balanced combination of protein and lipids is beneficial for maintaining health and improving adaptability to environmental stressors, particularly in crowded cultivation settings. The fattening stage, occurring between 35 to 45 days, focuses on optimizing feed efficiency with a protein diet of 30 to 35%. At this point, the emphasis shifts towards maximizing muscle mass and improving overall yield, preparing shrimp for harvest. Beyond quantity, the quality of protein is equally important. Diets incorporating highly digestible proteins with a balanced amino acid profile lead to better feed conversion rates, lower nitrogen excretion, and a stronger immune system—especially crucial in intensive farming conditions. Products like BioActio Health & Performance, a hydrolyzed chicken protein rich in bioactive peptides, demonstrate significant benefits. Research indicates that shrimp fed diets containing BioActio show improved survival rates when exposed to pathogens like Vibrio parahaemolyticus. Additionally, this product enhances water quality by reducing nitrogen and phosphorus levels, contributing to a more sustainable aquaculture practice. In conclusion, proper nutrition tailored to each developmental stage is vital for shrimp farming success. Solutions like BioActio not only support shrimp health and growth but also contribute to environmentally responsible aquaculture practices.
