Stimuler is a natural plant extract. The effective ingredient of extract is saponins, which are glycosides of phyto-steroids or terpenoids.

It stimulates the protein synthesis, the ecdysis of crustacean, shrimp, and crab and so on. So it can increase the growth rate of crustacean. Shrimp cannot produce the cholesterol that is the precursor of ecdysis hormone owing to lack of squalene oxidocyclase. So, cholesterol must be supplied through the shrimp feed. Cholesterol is changed to ecdysis hormone through multi-process in associated with enzymes. But, this multi-process is inhibited by many kinds of stress. In conclusion, direct supply of phyto-ecdysteroids in saponins is better than supply of cholesterol.

Each molt is triggered by a steroid hormone called ecdysone which promotes the pupa-to-adult molt.

The process of molting is called ecdysis and is controlled by the hormone ecdysone.

The effects of ecdysone, except for molting hormone, are as follows.

Stimulate growth in animals

Stimulate cell proliferation

Increase glyogen in tissues (like insulin hormone)

Prevent lipid peroxidation

Analgesic effect

Shrimp cannot produce the cholesterol that is the precursor of ecdysis hormone owing to lack of squalene oxidocyclase.

So, cholesterol must be supplied through the shrimp feed.

Cholesterol is changed to ecdysis hormone through multi-process in associated with enzymes. But, this multi-process can be inhibited by many kinds of stress or some other factors, as follows.

Diet cholesterol & absorption

Oxygen in water. Oxygen is used to hydroxylation.

Vitamin C is control factor of first step of hydroxylation.

Disease

Stress (ex, temperature).

In conclusion, direct supply of phyto-ecdysone is partially better than supply of cholesterol.
