OUR STORY BEGINS
We advance
science and health
Evermark Nutraceuticals LLP, widely known as HALLMARK, is a professionally driven manufacturing company with a legacy spanning over four decades. Our journey began in pharmaceutical manufacturing in the 1980s and expanded into poultry in 1986 and veterinary in 1990. In 2000, HALLMARK entered the Aqua Industry with a clear vision to develop scientifically proven, reliable and performance-oriented solutions for aquaculture farmers.
From Experience to Aquaculture Excellence
Four decades of manufacturing experience have shaped the way we think about products.
For HALLMARK, developing an aquaculture solution is not simply about creating a product. It is about understanding the environment in which that product will be used, observing real farm conditions and developing solutions around the challenges faced by farmers.
Our approach combines science, observation, experience and mathematics to create solutions designed for real-world aquaculture.
Because in aquaculture, there are no shortcuts.
No Magic. Only Mathematics.
