Baby brine shrimp nutritional analysis (according to San Francisco Bay Brand, Inc.) - crude protein - min 55%, crude fat - min 18.3%, crude fiber - max 19%, beta carotene (hence the orange color), lipids, essential unsaturated fatty acids.
In addition, I started to add some algae from the walls of the main pond. The suspension of live brine shrimp, green algae and diatoms should give enough nutrition for rapidly developing ranchu.
