Aquatic Organisms


Aquatic Research Organisms, Inc. (ARO), established in 1985, continues to supply quality test organisms to the environmental industry. Laboratory reared freshwater cultures of Pimephales promelas, Daphnia magna/pulex, Ceriodaphnia dubia, Hyalella azteca, Chironomus dilutus/riparius/tentans, and Lumbriculus variegatus are available year round, on demand. For biomedical research ARO provides lab reared Danio rerio and Oryzias latipes. ARO's seacoast location ensures a continuous supply of natural seawater for culturing Menidia beryllina and Americamysis (f.k.a. Mysidopsis) bahia and Leptocheirus plumulosus. Field collected marine organisms such as Ampelisca abdita, Fundulus heteroclitus and Mytilus edulis are seasonally available.

ARO has responded to the challenge of meeting the needs of our clients by keeping abreast of protocol revisions and new regulations. Recent additions to the ARO product line include; the Neocaridina denticulata (Japanese cherry shrimp), the freshwater annelid Tubifex tubifex and the terrestrial annelids, Enchytraeus albidus (white/pot worm) and Eisenia foetida (red/manure worm). We also recently introduced Folsimia candida, a terrestrial springtail. See the price sheets for a more complete list of available organisms. If you don't see the species required for your study, please contact ARO. If you are calling from an educational institution, please refer to code AALAS2020 when calling or emailing in.

Teachers ordering on school purchase orders are eligible for discounts on many of the organisms we sell.

Quality Assurance
Aquatic Research Organisms, Inc. maintains an on-going program of quality assurance to provide our customers with the highest quality organisms available. These programs include health monitoring and performance evaluation of organisms through the use of standard reference toxicants.

Health Monitoring
Aquatic Research Organisms, Inc. conducts health monitoring on most of its in-house fish breeding colonies. Populations are inspected annually by a certified independent laboratory. Specific pathogens are evaluated and compared to the expected occurrence within each species. Health monitoring reports are available on request.

Reference Toxicant Testing
Reference toxicant testing is performed monthly on selected species. Specific life stages are exposed to a known toxicant (e.g., sodium dodecyl sulfate.) The exposure is conducted over a pre-established series of concentrations which will yield mortality results sufficient to calculate an LC50. Reference toxicant data is charted and used to evaluate the overall health of the organisms over time.
