Exploring the Impact of Light Exposure on the Nutritional Quality and Metabolism of Muscle and Lipids in Indoor-Cultivated Pacific White Shrimp

A recent study by Dr. Baoliang Liu and colleagues has revealed that a continuous 24-hour light photoperiod significantly enhances the concentration of essential amino acids (EAAs) and polyunsaturated fatty acids (PUFAs) in the muscle of Pacific white shrimp (L. vannamei), while also promoting lipogenesis and the absorption of fatty acids. Conducted at Yuhai Hongqi Ocean Engineering Co., Ltd. in China, the research tested five different light-dark cycles and found that the 24L:0D condition produced the best nutritional outcomes in terms of muscle quality. The findings underscore the importance of light management in indoor aquaculture, suggesting that prolonged exposure to light can improve shrimp yield and nutritional value, while continuous darkness may lead to stress and reduced protein content. This research provides critical insights for optimizing shrimp farming practices and will inform future studies on the effects of lighting on aquatic species.
