TRPA Fish Biologists (TRPA) is a woman-owned fisheries consulting firm (Supplier Clearinghouse Women Business Enterprise [WBE] Verification Order Number 19000221) with extensive experience in fish monitoring, the analysis of instream flow needs, and the impacts of water resource project development on fishery resources. Over the past thirty-five years TRPA staff biologists have worked on over 300 separate projects: conducting instream flow studies, modeling instream water temperatures, evaluating fish habitat, monitoring fish populations, developing fish habitat use criteria curves, negotiating fishery resource protection provisions, writing construction project mitigation plans, supervising and conducting resource protection and salvage efforts for aquatic species (including Federally and State–listed fish and amphibian species) during stream channel and floodplain construction projects, preparing licensing documents, and completing environmental impact reviews and assessments. Projects on which TRPA has participated range in scope from backyard fish rearing ponds to billion dollar destination resort complexes, and have ranged in locations from intermittent high mountain streams to large rivers to coastal estuaries.
TRPA, located in the Arcata HUB Zone on the Redwood Coast of northern California, has performed fisheries research throughout the Pacific Northwest and Rocky Mountain area, New England, the East Coast, Hawaii, Guam, and Newfoundland, with an emphasis on northern and central California. Humboldt State University and its nationally-known and respected College of Natural Resources and Sciences provide TRPA with assistance from informed and dedicated graduate student labor, and the resources of an extensive fisheries library.
