The CDFW Shellfish Health Laboratory monitors and diagnoses known and emerging diseases in wild and farmed shellfish throughout the State of California.

Lab activities include:

  • inspecting and working closely with shellfish farms, marine aquaria, and research laboratories to prevent the introduction and transfer of disease agents and non-native species
  • collaborating with academic institutions and aquaria to contribute to the recovery of endangered native abalone populations
  • providing an early detection program for monitoring freshwater waterbodies throughout California for the presence of invasive freshwater (quagga and zebra) mussels
