- Just to add fuel to the fire, here's an excerpt from my notes on Dr. Michael
- K. Stopskopf's lecture at MACNA IV this past September. In this lecture he
- outlined his recommended quarantine procedure.
-
-
- Healthy Fish, Everyone's Goal: The Medical Care of Marine Tropical Fishes -
- Dr. Michael K. Stoskopf
- =============================================================================
-
- Dr. Michael K. Stoskopf was the first Chief of Medicine for the National
- Aquarium in Baltimore and served for a period of 8 years.
-
- Michael focused his talk on the quarantine of marine tropicals.
-
- The minimum quarantine period is 6 weeks.
-
- Prophylaxis - Any prophylactic treatment is a tradeoff between the stress
- induced by the treatment and the damaged caused by the potential
- pathogen the treatment is for.
-
- Freshwater Dips - every other day, 3 times. [I don't remember specific
- times but 3 minutes seems to stick in my head]
-
- Antibiotics - probably stupid to do as a prophylactic measure.
-
- Copper - copper is an immunosuppressant. Don't start a copper treatment
- until you're confident that there is no bacterial outbreak.
-
- Important Quarantine Intervals
-
- Post Shipment Stress - allow stress to subside.
-
- Post Copper Rest - allow inmmune system to recover.
-
- Post System Exposure Observation - acclimation of new animals to main
- display microfauna.
-
- Durations (and Quarantine Regimen)
-
- 1 Week - Rest and Pre-treatment (freshwater dips)
- 3 Weeks - Copper Treatment (.15 ppm)
- 1-2 Weeks - Post Copper Rest
- 1-2 Weeks - System Pre-Exposure
-
- System Pre-exposure - main display water is added to the quarantine
- tank in small quantities. The objective is to expose the new specimen
- to the main tank microfauna in a controlled setting. The new specimen
- may have never been exposed to some of the microfauna in the main
- display tank. After adding a small amount of system water you should
- observe the new animal for signs of disease and treat as necessary.
