Artemia biomass feeding to shrimp post-larvae nursing in a hapa. 5) revealed a high EPA content at 16-17 mg/g dry weight cysts. The average cyst size is 238 µm, with a hatching rate of 85 percent. The excellent nutritional quality of locally produced Artemia biomass and cysts and the small size of cysts opens the scope to promote marine aquaculture in Bangladesh and reduce dependence on imported cysts. Live or frozen Artemia biomass is an excellent diet for shrimp broodstock (Fig. 6), post-larvae nursing (Fig. 7) and first month juvenile in grow-out, and also for mud crab nursing. The umbrella stage of Artemia is essential for the zoea stage of crablets, which can significantly increase their survival (Hai et al. 2020) Artemia Biomass as Human Food Five innovative recipes were developed for Artemia as human food: Artemia kebab (Fig. 8), omelet (Fig. 9), water spinach fritters, coconut milk curry and jhal ferazi (Fig. 3). The recipes were well accepted by salt-farmer families, as well as aquaculture stakeholders. The new food items will contribute to tackling malnutrition of saltfarmer families. Summary Salt and coastal aquaculture farmers in Bangladesh are poor and may be the most climate vulnerable population in the world. A new climate-smart and nutrition-sensitive Artemia pond culture opens the scope to increase the productivity of coastal aquaculture, increase income and tackle malnutrition of salt farmers’ families.
