Artemia, commonly known as brine shrimp, plays a pivotal role in global aquaculture as a live feed for larval fish and crustaceans due to its exceptional nutritional profile and ease of enrichment (Figure 1). However, commercial applications beyond hatchery feed remain underexplored. This PROBLUE initiative investigates feasibility of expanding Artemia use into broader animal feed sectors, including finfish grow-out diets, poultry, and ornamental species, with a focus on sustainability, cost-effectiveness, and supply chain resilience.
The research evaluates key parameters such as protein digestibility, amino acid composition, lipid enrichment potential, and functional properties (e.g., immunostimulant and gut health). Comparative feeding trials were conducted using Artemia biomass—both dried and processed as meal—against conventional protein sources such as fishmeal and soybean meal. Preliminary findings indicate that Artemia-based feed formulations enhance feed conversion ratios, improve survival rates, and stimulate pigmentation and growth performance in select species. Furthermore, we assess the economic viability of scaling Artemia production through integrated saltworks, solar ponds, and circular aquaculture systems in developing countries. Particular attention is given to gender-inclusive value chain development and climate resilience in developing states.
The Artemia study demonstrates that Artemia is not only a premium hatchery feed but also a versatile ingredient with cross-sectoral potential in sustainable animal nutrition. These findings support the case for strategic investment in Artemia production as part of blue economy development frameworks.
