ALGAE - PHYTOPLANKTON
& PERIPHYTON ANALYSES
BSA provides exceptional phytoplankton and periphyton 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.
Algal species assemblages are excellent indicators of water body health. One
initial sign of water quality degradation is a shift in algal abundance and
species composition. Algae in both the phytoplankton and the periphyton quickly
respond to anthropogenic changes in water quality.
Based on known effects of water quality on algal communities in lakes and
streams the USEPA developed periphyton-based rapid bioassessment methods for
water quality. These assessments are based on taxonomic identification of
periphyton species, biomass as determined from measurements of chlorophyll a
and ash-free dry mass of samples, and analysis using other standard water
BSA provides expert-level phytoplankton and periphyton analysis of samples
using these USEPA methods or other standard methods, as our clients require.
Undesirable species, nuisance, and invasive species (exotics), may have
significant negative economic, social and ecological impacts. BSA provides
identification, enumeration, and biovolume measurements of invasive species
such as the invasive diatom Didymosphenia geminata and nuisance and noxious
algae such as Anabaena circinalis, Aphanizomenon flos-aquae, and Microcystis
aeruginosa. Data obtained from these analyses are used to effectively monitor
and manage exotic and nuisance species, which is necessary to maintain
satisfactory water quality conditions and preserve native populations.
BSA provides high quality, cost-effective aquatic analyses and services to
government and commercial clients. Each project we undertake is conducted in
accordance with client standards.
Algae also show potential in several biotechnology fields, including
bioremediation, carbon sequestration, and biofuel production. BSA can aid
clients in their efforts to expand algal uses by providing accurate
identifications of experimental algal communities.
BSA will provide your organization with accurate and timely algal
identifications with our phytoplankton analysis and periphyton analysis of
samples collected using various techniques. In addition to identification
services, BSA offers:
Client’s choice of Utermöhl, filtration, or wet mount counting techniques
Permanent Slides- Including HPMA, TSM, and Naphrax mounting methods
Monitoring of problematic taste and odor producing algae
Larval fish gut algal analysis
Biomass from chlorophyll a analyses / ash-free dry weight
Water quality and biodiversity indices calculations
Voucher collections of algal specimens are developed with permanent slides of
aquatic samples, which are mounted using the client’s choice of standard
BSA will provide you with superior phytoplankton analysis and periphyton
analysis of your samples.
Express services are available upon request.
