اولین مرکز توان افزایی و مهارت اموزی پرورش و تکثیر زالو در کشور
The knowledge-based industrial group Iran Leech Industry, operating under the Zalok brand, brings together experienced specialists and scientists in biotechnology, microbiology, animal science, and fisheries. In 2009 the group launched extensive research into leech production and farming, as well as specialized additives and supplements for the leech industry. In 2013 it succeeded in establishing and localizing the first leech breeding and farming facility in Isfahan, based on the Iranian Hirudo orientalis species with a high reproduction rate.
In 2016, Iran Leech Industry obtained official membership in the IAHH international leech association, showcasing Iran’s capabilities in the leech field to the world. During 2016–2017, thanks to the insight of our expert team, we secured membership in other reputable international bodies in under a year — including official membership in the British Hirudotherapy Association (BAH) and the Russian leech association (WHTO). Finally, in 2018, the group became the official representative of the Australia and Oceania Hirudotherapy Institute in Iran.
A precise, well-founded leech farm setup is one of the most critical points in the leech production cycle; any flaws in this process lead to losses for leech farmers. The main reason farms are set up incorrectly is taking advice from uninformed people with limited knowledge. Fortunately, Iran Leech Industry’s consultants, backed by comprehensive expertise, stay by leech farmers’ side and answer their questions all the way through the farm setup process.
Finding credible sources to deepen your knowledge of leech production and farming can be difficult and time-consuming — and often expensive as well. Iran Leech Industry, with over 10 years of experience in producing and breeding medicinal leeches, offers precise, well-structured, A-to-Z training right here on this website — built on international standards, covering every point required for standard production and breeding, and completely free of charge — to raise the awareness of leech farmers.
Like any other creature in an industrial farming cycle, leeches need medicines and supplements for maximum growth and reproduction. Proper leech nutrition is also a key requirement for obtaining the certifications needed to enter the market. For years, Iran Leech Industry has met leech farmers’ needs by producing the supplements leeches require and sterilized blood, backed by all the necessary laboratory testing.
Our Goals
The core mission of the Iran Leech Industry production group is producing the additives and supplements the leech industry needs — grounded in biotechnology and driven by research and development — improving production efficiency and lowering production costs on farms. To that end, applying knowledge, experience, and up-to-date global technology; complying with GMP and HACCP principles; drawing on the technical expertise of domestic specialists; attending to environmental considerations, safety, and medical hygiene as part of our professional mission; producing products that compete with foreign counterparts and earn positive field feedback; and ultimately helping raise the level of public health — these are the guiding principles of this production group.
The KataLeech supplement is one of Iran Leech Industry’s key achievements, developed and brought into production to treat leeches’ skin and fungal diseases and to lower water pH. This product resolved many of leech farmers’ concerns about finding a suitable medicine and supplement for these problems.
The Leech Science book is one of the valuable works by Iran Leech Industry’s experts, written to grow leech farmers’ knowledge and help them understand leeches better. The leech’s way of life, body anatomy, positive effects, farming and breeding methods, and many other leech-related topics are explained in detail in this book.
Producing products with a high level of safety and health — fully hygienic, mindful of environmental considerations, and competitive with foreign products — is another of this group's achievements.
For years, this group has met customers' needs with precise, thorough support, and its emergency services have put leech farmers' worries to rest.
A research team continuously working on the leech industry's challenges and producing the essentials the leech field needs.
