Improve Your Understanding of Water

JonahWater delivers insight into aquatic ecosystems, both freshwater and marine

Our JonahWater services answer questions about species in aquatic ecosystems

We quantify aquatic assemblages by sequencing aquatic environmental DNA .

Using both Quantitative PCR and Next Generation Sequencing, we quantify phytoplankton, macroinvertebrates, fish, and other vertebrates in water.

JonahWater gives you the capacity to quantify:

  • Phytoplankton such as cyanobacteria, diatoms, and green algae
  • Macroinvertebrates such as mayflies, chironomids, and mussels
  • Vertebrates such as fish, mammals, reptiles, and amphibians

Sequencing of environmental DNA has the potential to transform our understanding of aquatic ecosystems. Using NGS and qPCR gives managers better data cheaper and faster than traditional techniques. All from 250 milliliters of water…

For quantifying organisms in water, choose from qPCR or Next Generation Sequencing (NGS)

Single or Few Species

To quantify single species or a small number of species (<5), we recommend qPCR. qPCR works best for small numbers of species when you want to quantify the absolute abundance of DNA in water. False negative rates are lowest here. We also use qPCR for source tracking of E. coli in water.


To quantify the relative abundance of species in assemblages, we recommend Next Generation Sequencing (NGS). NGS quantifies large numbers of species within a given taxonomic group (phytoplankton, insects, fish, vertebrates…). NGS is best when relative abundance is desired.
