| Bacterial and Parasitic Diseases of Fish | Bacterial and parasitic diseases are very common problems in pet fish. Shotgun treatment
of fish should never be based simply on gross appearance of clinical signs and
lesions without the benefit of diagnostics. Diagnostic testing for bacterial and parasitic
diseases is simple to do; many tests can be done on ambulatory visits. Because of
unique media requirements and incubation temperatures for some fish pathogens, it
is vital to develop a relationship with a diagnostic laboratory that can provide these
needs and correctly handle diagnostic samples from aquatic animal patients. When
logical treatment strategies are initiated and supported by diagnostic testing,
a successful outcome is possible. Identification of the correct pathogens also allows
an educational opportunity for discussions on prevention and biosecurity practices
with the owners and clients. Also, and, although fish are cold-blooded, there are
some bacterial and parasitic pathogens that are zoonotic.

| Book Ordering Information | Fundamentals of Ornamental Fish Health is a complete guide to managing the health and
well-being of ornamental aquatic animals. Grounded in the foundations of fish medical care,
the book summarizes nonlethal aquatic diagnostics and medicine, putting the information
within a clinical context. Providing a comprehensive overview of the subject, Fundamentals of
Ornamental Fish Health equips aquatic animal health professionals with all the information
needed to competently and effectively treat these patients, from transporting and examining fish
to diagnostic techniques and the identification and treatment of specific diseases and syndromes.

| Diagnostic Cytology of Pet Fish | Cytology is the cornerstone of diagnostic techniques in fish medicine. It
involves the evaluation of patient cells and an assessment of associated bacterial
and fungal populations, protozoan infestations, and metazoan parasites
or their eggs. The benefits of cytology include easy sample collection
with minimal patient risk, relatively low cost, and rapid results. Interpretation
of findings can help to establish a diagnosis and initiate a rapid therapeutic
plan.

| Respiratory Diseases in Pet and Ornamental Fish | Living in an aquatic environment where oxygen is in less supply and harder to extract
than in a terrestrial one, fish have developed a respiratory system that is much more
efficient than terrestrial vertebrates. The gills of fish are a unique organ system and
serve several functions including respiration, osmoregulation, excretion of nitrogenous
wastes, and acid-base regulation. The gills are the primary site of oxygen
exchange in fish and are in intimate contact with the aquatic environment. In most
cases, the separation between the water and the tissues of the fish is only a few
cell layers thick. Gills are a common target for assault by infectious and noninfectious
disease processes. Nonlethal diagnostic biopsy of the gills can identify pathologic
changes, provide samples for bacterial culture/identification/sensitivity testing, aid
in fungal element identification, provide samples for viral testing, and provide parasitic
organisms for identification. This diagnostic test is so important that it should be
included as part of every diagnostic workup performed on a fish.

| Toxicology of Aquarium Fish | Fish have a very intimate relationship with their surrounding aquatic environment,
surrendering them vulnerable to waterborne toxicities. Most
aquarium fish live in a closed system (water has to be manually removed
and added to be renewed), so the effects of such toxins can be cumulative
and devastating. Most cases of toxicity are due to deficiencies in husbandry
and tank maintenance. Poor water quality kills more fish than infectious
agents, making client education a very important preventive tool for aquatic
practitioners. This article includes a discussion of toxicities related to water
quality, chemotherapeutics, pesticides, and household substances.
