REGIONAL BIOSECURITY:OPERATIONAL BIOSECURITY AND

DIAGNOSTIC SURVEILLANCE

• Charles Laidley, OPERATIONAL BIOSECURITY

• Amanda Lowrey and Clyde Tamaru, DIAGNOSTIC SURVEILLANCE

Stakeholder Input obtained via two workshops (e.g., Oahu and Hawaii

Diagnostic and Surveillance Objectives - Year 1:

• Objective 1: Establish a local diagnostic laboratory with PCR technology able to provide rapid turn around time.

• Objective 2: Hold workshop with Koi producers to solicit participation and input in establishing health status of Hawaii’s koi with regard to koi herpes virus disease (KHVD)

• Objective 3: Establish pro-active screening methods for KHVD

• Objective 4: Conduct initial survey of KHVD in farmed and feral koi populations statewide

• Objective 5: Produce technical handouts of resulting information. Information obtained is to also be included in the Operational Biosecurity handouts.

• Objective 6: Conduct follow up workshop to disseminate information and begin discussions on the challenges and opportunities of establishing a health certificate program for farmed koi.

Diagnostic and Surveillance Objectives - Year 2

• Objective 1: Increase capacity of local diagnostic laboratory to include detection of Piscirickettsia-like organism (PLO) that infects tilapia.

• Objective 2: Conduct survey for Hawaii Tilapia Piscirickettsia-like organism (HTPLO) in farmed and feral tilapia populations statewide

• Objective 3: Extend survey to the whole CTSA region.• Objective 4: Produce technical handouts of resulting information.

Information obtained is to also be included in Operational Biosecurity handouts.

• Objective 5: Conduct follow up workshop to disseminate information and begin discussions on the challenges and opportunities of establishing a health certificate program for farmed

tilapia.

Tilapia is the fish used almost exclusively in aquaponics operations in Hawaii.

• Tolerates low DO levels (e.g., 0.2 ppm)

• Tolerates high total nitrate levels (>400 ppm)

• Tolerates high TAN levels (45 ppm) @ pH 6.0
