Product Application
DMPT is regarded as a fourth-generation aquatic feeding attractant and ranks among the most potent fish-inducing agents currently available. Its remarkable luring effect is vividly nicknamed a “fish-biting stone” — even when coated onto ordinary stones, it can draw fish to take bites.
It is most widely used in fishing baits, greatly boosting bait appeal and encouraging fish to take the hook more readily. For industrial applications, DMPT acts as an eco-friendly aquatic feed additive, which stimulates feeding intake in aquatic species and accelerates their growth.
