About Us

The world leader of fish identification hardware, software and data services providing you with actionable animal intelligence.

For over 25 years Biomark has been a worldwide supplier in electronic identification technology to the aquaculture and natural resource communities. 

PIT tags have been used for over twenty-eight years to permanently identify individual animals. Beginning with fisheries studies, the use of PIT tags has expanded to include mammals, reptiles, amphibians, birds and many other animals and objects. More recently, the aquaculture sector has embraced this technology realizing the value of PIT technology use as a reliable and effective method of research, monitoring, and management of individual animals. 

PIT tags, also known as ‘microchips’ or electronic identification (EID) allow researchers to safely mark most species internally without altering external appearance.  In almost all cases the tag will stay with the animal for its entire life cycle.  The small size of PIT tags virtually eliminate any negative impact on animals with little or no influence on growth-rate, behavior, and health or predator susceptibility when tagged using best practices and methods.

Biomark understands the importance of communication within the aquaculture community. We continually work to provide information and make suggestions to improve research and production methods as they relate to animal health monitoring. We strongly suggest that when choosing identification markers one considers the importance of having consistency and standardization. There are a variety of PIT tag frequencies, manufacturers and tag readers that may or may not always be compatible. We suggest using products compatible with ISO standard 11784/11785.  Biomark supplies the highest quality and highest performance ISO standard products available in the world.

Biomark first opened in July, 1990 and in 1991, moved to its permanent location in Boise, Idaho, USA. Product innovation has always had a strong foundation at Biomark. In the 1990s Biomark pioneered the first commercially available custom PIT tag detection systems as well as tagging and data collection tables. During the next decade Biomark played a major role in designing and developing fabrication techniques to reliably operate PIT tag antennas underwater (a major breakthrough in evaluation and monitoring technique).  Biomark has emerged as a worldwide leader in PIT tag products for fisheries, aquaculture and wildlife. From innovative, first of their kind, tag injection systems, waterproof readers and automated data collection stations, to individual identification systems coupled with biomass estimation, Biomark delivers the best in products and services to its customers.
