Gaffkaemia

Gaffkaemia is a lethal disease that primarily affects lobster species, particularly the American lobster (Homarus americanus) and the European lobster (Homarus gammarus). The disease is caused by the bacteria Aerococcus viridans var. homari, which is typically transmitted through the water or direct contact with infected lobsters.

Symptoms and Diagnosis

The symptoms of gaffkaemia are often subtle and may not be immediately noticeable. Infected lobsters may exhibit lethargy, loss of appetite, and a general decline in health. In advanced stages, the lobster's shell may darken and the animal may become unresponsive.

Diagnosis of gaffkaemia is typically confirmed through laboratory testing. This may involve culturing samples from the lobster's hemolymph, or blood, to identify the presence of Aerococcus viridans var. homari.

Treatment and Prevention

There is currently no known cure for gaffkaemia. Once a lobster is infected, the disease is typically fatal. Prevention is therefore crucial in managing gaffkaemia. This can involve monitoring water quality, isolating infected lobsters, and implementing strict biosecurity measures to prevent the spread of the bacteria.

Impact on Lobster Populations

Gaffkaemia poses a significant threat to lobster populations, particularly in areas where the disease is prevalent. Outbreaks can result in high mortality rates, impacting both wild populations and aquaculture operations.
