MACROINVERTEBRATE ANALYSES
BSA provides exceptional
macroinvertebrate analyses at research quality, cost-effective standards for
government and commercial clients. Each project we undertake is conducted in
accordance with prescribed client standards for quality of services in a
macroinvertebrate analysis.
Biological Assessment
Benthic macroinvertebrates are excellent biological indicators.
Macroinvertebrates collected from aquatic systems are used to evaluate the
health and characteristics of a body of water, thereby providing our clients
with key ecological information necessary for making informed management
decisions. To meet the biological integrity objectives of the Clean Water Act,
the USEPA developed rapid bioassessment methods of water quality using
macroinvertebrates.
Samples are identified according to the methods and procedures specified by the
client or the indicated protocol. We can identify and enumerate aquatic
insects, gastropods, amphipods, bivalves, leaches, oligochaetes and
chironomidae larvae. All sample results are entered into our databases and
reviewed for quality assurance. As an additional service, BSA prepares
permanent slide mounts of macroinvertebrate samples using standard methods for
development of client voucher collections.
Gut Analyses
BSA also identifies macroinvertebrates obtained from freshwater fish gut
samples. These analyses are useful in exotic and invasive species monitoring
and management, as well as in endangered species protection.
Express services are available upon request.
