Dmpt (dimethyl β-propionyl thiotepa) is a widely used feed attractant in aquaculture and fishing, effectively enhancing the appeal of bait to fish. By mimicking chemical signals found in natural food sources, it stimulates the olfactory and gustatory systems of fish, thereby increasing their feeding desire ✨.

In practical applications, mastering the correct usage of dmpt is particularly crucial, as excessive addition may lead to adverse effects, such as causing fish to avoid the bait or reducing its palatability.
DMPT is typically available in powder or liquid form and is recommended to be added to bait at a ratio of 0.1% to 0.3%. For example, adding 0.1 to 0.3 grams of DMPT per 100 grams of base bait can achieve optimal fish-attracting effects. When using, first dissolve DMPT in a small amount of water, then evenly spray it onto the bait surface, mix thoroughly, and let it sit for 10-15 minutes to allow full penetration.

Additionally, fish sensitivity varies with seasons and water temperatures, making the effects more pronounced in spring and autumn when temperatures are moderate. In summer, higher temperatures require reducing the dosage to avoid excessive stimulation.
It is worth noting that DMPT is not a universal solution; it is primarily suitable for freshwater fish species sensitive to odors, such as crucian carp, carp, and grass carp. When used appropriately in wild fishing, pit fishing, or competitive angling, it can significantly improve catch rates. However, its maximum effectiveness can only be achieved by combining it with bait selection, pit site selection, and weather assessment.

High-purity DMPT attractant, with fine powder texture and fast dissolution speed, blends seamlessly into the bait with just a light stir. A small amount each time releases a faint sweet aroma, and within minutes of spreading the bait, fish activity emerges. The most surprising benefit is the extended fish retention—no longer a "quick bite and leave" scenario, but sustained bites with continuous hook-ups, truly exhilarating! Especially during early morning and evening hours, when paired with corn kernels or commercial baits, the results are exceptionally stable, as if the bait has been equipped with a "signal light."

Correct Usage of DMPT:

Among fishing enthusiasts, dmpt has attracted much attention as an efficient bait.

1、 Principle and Applicable Scenarios of DMPT
DMPT simulates the natural warning response of fish and stimulates their active foraging. Research has shown that its metabolites can form a feeding signal band in water that lasts for 12-18 hours.

-Best use season: The effect is most significant when the water temperature is 15-28 ℃, and it should be used with fermented fish bait in winter
-Applicable fish species: Upstream active fish such as perch, grass carp, etc. have a response rate of 82%.

Common Misconceptions and Solutions:

Misconception 1: "Adding DMPT yields faster results"
Cracking: Overuse can alter the structure of bait, resulting in a 28% decrease in the bait hooking rate (measured data)
Misconception 2: 'New bait directly loaded onto DMPT'
Cracking: The bait must complete a 24-hour awakening period, otherwise the effective ingredient decomposition rate can reach up to 63%
Misconception 3: 'Sensitive waters can be physically replaced'
Cracking: Electronic fish lure has insufficient penetration within 5 meters, DMPT is still the mainstream choice 

Applicable scenarios and recommendations:

DMPT focuses on the penetration of fishy odor, especially suitable for:
1. Target fish species: crucian carp and carp, with significant environmental effects in streams or black pits.

2. Condition optimization: Use when the water temperature is low or the fish mouth is not active. Low temperature combined with silkworm pupa liquid can improve feeding efficiency.

3. Dosage control: The proportion is strictly between 0.3% and 5%, and excessive use can easily lead to dead nest; Regularly test the formula for adjusting water conditions.
