One dietary manganese response curve is not a tank dose
The evidence library is allowed to change in public. This page preserves the revised boundary, why it moved and which guides were affected.
What changed
The feeding and molting guides now include a six-diet manganese experiment while separating its short complete-formulation response from a universal requirement, aquarium-water dose, supplement recipe, incomplete-molt treatment and health claim.
Why it changed
The study used three 50-shrimp tanks per diet for 30 days and reported its highest growth percentages and antioxidant-enzyme activities at 62.69 micrograms per gram of finished feed. The control already contained manganese, all tanks shared recirculating water, biochemical sample-to-tank mapping was unclear and survival, feed conversion, tissue manganese, deficiency signs, molting, reproduction and long-term safety were not reported.

Affected practical guides
A public change is not automatically a retraction. A source may be added, a scope narrowed, a gap refined or an error corrected. The current guide and registry record own the current wording.
