Project: IDENTIFYING CYANOBACTERIAL HARMFUL ALGAL BLOOM TOXINS IN DELTA INVERTEBRATES: IMPLICATIONS FOR NATIVE SPECIES AND HUMAN HEALTH

Description: Cyanobacteria harmful algal blooms (CHABs) are a growing water quality problem in the Delta, and filter-feeding invertebrates compound risks associated with CHABs by biomagnifying cyanotoxins, specifically Microcystis (MC). It is critical to determine the extent of MC accumulation in Delta shellfish since these organisms are consumed by native species, including Sturgeon, and by humans. Funding for this Project will be used for research that will fill an important data gap concerning MC contamination in brackish and freshwater shellfish and the implications for managed species, their communities, and human health risks.

Reference Number: 3600BQ2096021

Implemented By: San Francisco Estuary Institute

Objective: This project has four objectives: 1. Determine the timing, range of concentrations, duration of contamination, geographic distribution and effects of species and organism size on MC/STX accumulation/depuration in shellfish, including habitats used by native and anadromous fish species. 2. Examine the bioaccumulation of MC/STX in shellfish in comparison with detections of MC/STX, cyanobacteria species in water, and nutrient information. 3. Elucidate risk of MC/STX contamination in Delta food-webs and potential risks to human shellfish consumers. 4. Coordinate with the Delta Regional Monitoring Program and the Interagency Ecological Program to improve understanding of CyanoHAB presence and related toxicant stressors on native fish species.
