We conduct over a thousand acute and chronic WET tests annually as well as numerous tests of pure compounds and formulations such as dispersants, surfactants, polymers, and biocides.  We have the experience and facilities for testing cold-water, warm-water, marine, estuarine, and freshwater species. 

At Coastal Bioanalysts we rear commonly-used species in our culture facility to ensure availability 365 days/year and the use of test organisms that are healthy, free of shipping stress, and of appropriate age or life stage. These include four freshwater species (C. dubia, P. promelas, D. magna, S. capricornutum) as well as two marine species (M. bahia, C. variegatus).  We have experience with all of the species listed below:


Freshwater Species:

Ceriodaphnia dubia 
Pimephales promelas 
Daphnia magna 
Daphnia pulex 
Oncorhynchus mykiss 
Hyalella Azteca 
Selenastrum capricornutum
