Optimal dietary krill meal to fishmeal ratio in shrimp diets

Offentlig prosjektsammendrag

In response to challenges posed by stagnant fish meal supplies and rising prices, feed formulations for marine shrimp have undergone adaptations. This evolution has entailed a gradual shift toward alternative protein sources like plant materials and rendered animal by-products. However, this transition has introduced certain concerns such as the potential for nutrient deficiencies, reduced attractiveness and palatability, as well as antinutritional factors that can inhibit feeding response, hinder nutrient absorption, and escalate production expenses. To effectively address these concerns, the incorporation of krill meal into the diet presents a promising solution. Nonetheless, a significant knowledge gap remains concerning the optimal balance between reducing fish meal content and introducing krill meal into the formulation. This essential ratio has not yet been conclusively determined, making it a pivotal area of exploration and advancement.
