Multi-species and Single-species (freshwater)

Products that contain both metabarcoding and qPCR tests, for detecting species in freshwater systems, such as rivers, ponds and lakes.

Not for use in estuarine systems. In estuarine systems please use our marine water products, for either multi-species or single-species.

Key info and overview of all freshwater multi-species (metabarcoding) tests available at the bottom of this page. Scroll down below the product options to read key info on each test, plus an overview of our freshwater multi-species offering.

What do I receive?

For each product purchased, you will receive:

  • One sampling kit, to collect / store / transport your eDNA
  • One report per test ('assay')

Kit options

Aquatic: contains a hand-operated syringe, for manually pushing water through the kit's eDNA filter.

Aquatic - for pump: does not contain a hand-operated syringe. Instead contains tubing and adaptors for use with powered peristaltic pumps (e.g. Vampire Samplers). Pumps are not included and are not supplied by NatureMetrics.

Regional considerations

Multi-species:

The ‘Bivalves (excl. Unionid mussels)’ and ‘Unionid mussels’ tests are designed for use in the UK. They can be used outside of the UK, but we have less information on what they will detect. All other freshwater tests can be used in freshwater systems across the globe.

 

Single-species:

The single-species, qPCR tests ('assays') we offer have been developed and validated in specific regions of the world. They can perform equally well outside of these regions, but, when deploying them outside of their validated regions, we advise running some preliminary surveys, before deploying the tests more widely.

Regions in which each test has been validated are listed below:

Global:

  • Chytrid fungus (Batrachochytrium dendrobatidis)

Europe & North America:

  • Herring (Clupea harengus)

Canada & USA:

  • Brook trout (Salvelinus fontinalis)
  • Brown trout (Salmo trutta)
  • Lake Sturgeon (Acipenser fulvescens)
  • Rainbow trout (Onchorynchus mykiss)
  • Redside dace (Clinostomus elongatus)
  • Round whitefish (Prosopium cylindraceaum)

Canada:

  • Blanding's turtle (Emydoidea blandingii)
  • Burbot (Lota lota)
  • Silver shiner (Notropis photogenis)

Europe:

  • Chytrid fungus (Batrachochytrium salamandrivorans)
  • Crayfish plague (Aphanomyces astaci)
  • European eel (Anguilla anguilla)
  • Great crested newt (Triturus cristatus) (not for UK licensing)
  • Signal crayfish (Pacifastacus leniusculus)

UK & Ireland:

  • Arctic char (Salvelinus alpinus)
  • Chinese mitten crab (Eriocheir sinensis)
  • Dreissenid mussels (genus level)
  • White-clawed crayfish (Austropotamobius pallipes)
  • Zebra mussel (Dreissena polymorpha)

UK:

  • Great crested newt (Triturus cristatus) (for UK licensing)

Freshwater multi-species tests - key info

Bivalves (excl. Unionid mussels)

Used to identify mussels in the family Veneridae, and can detect presence of zebra mussels, quagga mussels, and Asian clams.

Designed for use in the UK. Can be used outside of the UK, but we have less information on what it can detect.

Fish

Optimised for ray-finned fish (Actinopterygii) such as tuna, seahorses, gobies, cichlids, flatfish, wrasse, perch, anglerfish and pufferfish.

This test does not perform as well for detecting sharks and rays.

In some cases, this test does not provide species level data, e.g. river lamprey and brook lamprey; ide and dace.

Insects

Detects mayflies, stoneflies, caddisflies, beetles, mussels and other invertebrates and insects. Particularly useful for detecting chironomid flies (non-biting midges) which are used in many parts of the world to monitor freshwater health.

Identifies many taxa to species level that are otherwise difficult to disambiguate (e.g. chironomids).

Detects many species that are important indicators of water quality.

Designed for arthropods, this test carries a bias towards soft-bodied taxa (e.g. Diptera spp.) over hard-bodied taxa (e.g. Coleoptera spp.).

Mammals

Detects aquatic and semi-aquatic mammals, and many terrestrial mammals who have visited the water or are nearby – as terrestrial mammal eDNA can often end up in nearby water courses, via runoff.

Detection of terrestrial species can be sporadic as they are less likely to contact water and deposit eDNA. Detection of terrestrial species is dependent on the species either directly interacting with water and/or their eDNA being transported from other waterbodies/via runoff.

Vertebrates

Detects fish, amphibians and mammals, generally to species level. Some closely related fish species, such as perch and zander cannot be separated.

Terrestrial mammal eDNA can often end up in nearby water courses, so this test can have the added benefit of delivering detections for some terrestrial vertebrates.

Results are often comprised of a high percentage of fish species (especially ray-finned fish, Actinopterygii) and can include marine mammals, and high (family) level identification for some bird species.

Birds and reptiles can be detected, but this test should not be relied upon as a comprehensive test for these groups.

Freshwater tests - overview

Kits

All tests are available for either our standard aquatic kit or our aquatic kit - for pump.

The same choice of tests is available for aquatic kits as it is for the aquatic kit - for pump. Your choice of aquatic kit does not impact which tests are available.

Kit instructions

Kit instructions available here.

Terrestrial eDNA

Vertebrate and mammal tests may detect nearby terrestrial species.

Terrestrial mammal eDNA can often end up in nearby water courses, via runoff. This means our vertebrate and mammal tests can detect not only aquatic and semi-aquatic mammals, but terrestrial mammals who have visited the water or are nearby.
