I am looking for an article in which a plant or combination of plants with a low dose (0.001 of food) is used to improve both growth and the immune performance of rainbow trout. The lowest dose of the crude plant as a supplement in the articles I dealt with was 0.01, But I'm looking for plants with a lower dose (about 0.001 or lower).
Yes, Grass or paddy dust can be used as a source of fiber during preparation of fish feed, more suitable for herbivorous fish like, Ctenopharyngon sp.
Enteromorpha & Rice bran (deoiled) can be used for marine fish varieties. Moringa leaves after boiling them in water can also be used for both varieties.
Yes, one of these plants is the stinging nettle - Urtica dioica L. Many years ago, when good industrial feeds for juvenile salmon fish were not available, in the spring it was added to hand-made wet (semi-moist) food as a vitamin supplement. To do this, young nettle was scalded with hot water, and then crushed using a meat grinder.

Thanks a lot for your answers. Unfortunately, I realized that I made a mistake during typing my question, and the words of my problem were displaced, and my meaning was not clear. Now I corrected my question. Would you please do a favor and answer me again?
Apart from the examples already given, a few more are leaves of Ocimum tenuiflorum and Prosopis juliflora.
