99% DMPT Dimethyl Beta Propiothetin Hydrochloride Powder Natural Aquaculture Fish Attractant

4337-33-1 Natural Aquaculture fish attractant Dimethyl-beta-propiothetin hydrochloride powder 99% DMPT

The Introductction of DMPT

Dimethyl-beta-propiothetin, abbreviated as:DMPT, exists in two ways: one is Dimethyl-beta-propiothetin hydrochloride, CAS: 4337-33-1, molecular formula C5H11SO2Cl, and the other is Dimethyl-beta-propiothetin hydrochloride. Molecular weight 170.66. The other one is Dimethyl-beta-propiothetin hydrobromide, CAS: 20986-22-5. Molecular formula C5H11SO2Br , molecular weight 216.12 .
Other names: beta-Dimethylsulfoniopropionate (abbreviation: DMSP), dimethyl-propiothetin, dimethylmercaptopropionic acid, dimethyl carboxyethyl sulfonium chloride, etc.
DMPT is white crystalline powder, easily soluble in water, easily deliquescent, easily caked (caking does not affect the effect).
Dimethyl-β-propionic acid thietin (DMPT) can be stimulated by the aquatic animal's sense of smell to accept low concentration of chemical substances in the water body, which can distinguish chemical substances and is extremely sensitive, and the folds within its smell mumbling can increase its contact area with the external water environment to improve the sensitivity of smell. Therefore, fish, shrimp and crab have a strong physiological mechanism to attract food to the special odor of DMPT, and DMPT follows this unique habit of aquatic animals to increase the feeding frequency of aquatic animals. As a growth promoter for aquatic animals, DMPT has a significant effect on the feeding behavior and growth of various marine and freshwater fish, shrimps and crabs. It causes aquatic animals to bite bait more often, and its feeding stimulating effect is 2.55 times higher than that of glutamine (glutamine is the most effective feeding stimulant known for most freshwater fishes before DMPT).

The Application & Function of DMPT

The most typical use of DMPT is as a fishing bait to improve the bait's attractiveness and make the fish bite easily.
The industrial use of DMPT is as a green aquatic feed additive to promote feeding and increase the growth rate of aquatic animals.

1. Feeding inducing effect
DMPT, as an aquatic animal feeding and growth promoter, has a significant effect on the feeding behavior and growth of a variety of marine and freshwater fish, shrimp and crabs.

2. Efficient methyl donor, growth promoting effect
The (CH3)2S-group on the DMPT molecule has the function of methyl donor, which is effectively used by aquatic animals to promote the secretion of digestive enzymes in the animal's body, promote the digestion of fish and absorption of nutrients, and improve the utilization rate of feed.

3. Improve the anti-stress ability and anti-osmotic pressure effect
It improves the motility and stress resistance of aquatic animals (high temperature and hypoxia resistance), improves the adaptability and survival rate of juvenile fish, and can be used as an osmotic pressure buffer in the body to improve the resistance of aquatic animals to osmotic pressure changes.

4. With ecdysone like effect:
Stronger ecdysone like activity, increase the speed of shrimp and crab shelling, especially in the middle and late stages of shrimp and crab culture, the effect is more obvious.

5. With hepatoprotective function
DMPT has hepatoprotective function, which can not only improve the health status of animals, reduce the viscera/body weight ratio and improve the edibility of aquatic animals.

6. Improving meat quality
Dimethyl-β-propionic acid thapsigargin (DMPT) can improve the meat quality of farmed products, make freshwater species present seafood flavor and improve economic value.

7. Antibacterial effect
DMPT also has similar health care and antibacterial effects as "allicin".

【Applicable objects】:Freshwater fish: carp, crucian carp, eel, eel, rainbow trout, tilapia, etc.; seawater fish: rhubarb, real sea bream, turbot, etc.; crustaceans: shrimp, crab, etc.
【Dosage】: Add 0.2-0.4g of pure product per kg of material for feed, and 0.4-1g is the recommended dosage for fishing, which is effective in spring, summer and autumn when the water temperature is high and mildly hypoxic. It performs well in low oxygen waters, gathering more fish and lasting for a long time.
【Residual problems】: DMPT is a naturally occurring substance in aquatic animals, there is no residual problem and can be used for a long time.
