Abstract
Blue crab aquaculture faces challenges in optimizing feed formulations that balance nutritional requirements with sustainability. This study evaluated three innovative feed formulations incorporating unique ingredient combinations: a specialized high-protein formulation using novel protein hydrolysates (D1), a marine-based diet enriched with bioactive compounds from sustainable sources (D2), and an advanced plant-based formulation with enhanced digestibility through fermentation (D3). Growth performance, survival, energy conversion efficiency, molting frequency, and meat quality were assessed over 16 weeks. The marine-based diet (D2) achieved superior results with 92% weight gain and 95% survival rate, significantly outperforming the commercial control. This research demonstrates the potential of novel ingredient combinations and processing techniques in enhancing blue crab aquaculture productivity while addressing sustainability concerns.
期刊介绍：
Aquaculture International is an international journal publishing original research papers, short communications, technical notes and review papers on all aspects of aquaculture.
The Journal covers topics such as the biology, physiology, pathology and genetics of cultured fish, crustaceans, molluscs and plants, especially new species; water quality of supply systems, fluctuations in water quality within farms and the environmental impacts of aquacultural operations; nutrition, feeding and stocking practices, especially as they affect the health and growth rates of cultured species; sustainable production techniques; bioengineering studies on the design and management of offshore and land-based systems; the improvement of quality and marketing of farmed products; sociological and societal impacts of aquaculture, and more.
This is the official Journal of the European Aquaculture Society.
