Flukes and Sick Guppies (8 pages) tackles the problem of why guppies die for “no good reason.” It starts with the author’s discovery of skin flukes (Gyrodactylus species) on her own guppies. Apparently, these Monogenean parasites have been a major, long-standing pathogen of the guppy (Poecilia reticulata). The author describes treatments and disease management strategies. Photo (magnified) shows Gyrodactylus flukes feeding on the outer mucus layer of a heavily infested salmon.
Stopping an outbreak of Fish TB using UV sterilizing filters instead of tearing tanks down and starting over. Managing mycobacteria rather than eradicating them. Scientific surveys on the presence of mycobacteria in the aquarium fish trade.
Mycobacteriosis in Aquarium Fish, a 15 page article, provides vital information that fish keepers can use to prevent—or deal with—“Fish TB.” Scientific surveys show that almost half of fish deaths due to unknown causes are due to mycobacteriosis. Article is based on the author’s experience fleshed out with the latest scientific research. Every fish keeper, whether professional fish breeder or beginning aquarium hobbyist, should read this.
