Overview of Urban Aquaculture

This 6-page fact sheet written by Emily H. Roan, Laura Tiu, Roy P.E. Yanong, Matthew A. DiMaggio, and Joshua T. Patterson and published by the UF/IFAS Program in Fisheries and Aquatic Sciences, School of Forest Resources and Conservation provides introductory information for people interested in engaging in commercial or hobby-scale aquaculture in urban or suburban areas. It introduces three common types of urban aquaculture systems, describes the resources and challenges unique to urban aquaculture, and includes a handy “getting started” section.

Cryptobia iubilans in Cichlids

Figure 1. Typical granuloma seen in a wet mount of stomach tissue from an African cichlid with Cryptobia iubilans infection. The section is unstained and is examined with a light microscope (100x) After many years of diagnostics at the University of Florida and at other laboratories around the country, it appears that Cryptobia iubilans is not uncommon among cichlids, and that environmental and other factors determine the extent of disease.This 3-page fact sheet was written by Ruth Francis-Floyd and Roy Yanong, and published by the UF Department of Fisheries and Aquatic Sciences, September 2014.

Koi Herpesvirus Disease (KHVD) (VM149/VM113)

Figure 1. Koi with mottled gills and sunken eyes due to koi herpesvirus disease.Koi herpesvirus (KHV) is a highly contagious virus that causes significant morbidity and mortality in common carp varieties. Common carp is raised as a foodfish in many countries and has also been selectively bred for the ornamental fish industry where it is known as koi. The first recognized case of KHV occurred in the United Kingdom in 1996. Since then other cases have been confirmed in almost all countries that culture koi and/or common carp with the exception of Australia. This 9-page fact sheet is intended to inform veterinarians, biologists, fish producers and hobbyists about KHV disease. Written by Kathleen H. Hartman, Roy P.E. Yanong, Deborah B. Pouder, B. Denise Petty, Ruth Francis-Floyd, Allen C. Riggs, and Thomas B. Waltzek, and published by the UF Department of Fisheries and Aquatic Sciences, April 2013.

Lernaea (Anchorworm) Infestations in Fish (FA185)

Figure 2. Koi infested with numerous female LernaeaLernaea species, commonly known as “anchorworms,” are crustacean, copepod parasites that can infect and cause disease and mortality in many types of freshwater fishes, especially wild-caught and pond-raised species. Infestations with Lernaea are most prevalent in the summer months and occur more commonly in stagnant or slow-moving water bodies. This 4-page fact sheet was written by Natalie Steckler and Roy P. E. Yanong, and published by the UF Department of Fisheries and Aquatic Sciences, December 2012.

Argulus (Fish Louse) Infections in Fish (FA184)

Figure 1. Adult Argulus sp. Note eye spots and round suckers on “head” end, and spermatheca on “back” posterior end.Argulus species (Family: Argulidae), more commonly known as fish lice, are members of a large group of branchiuran parasites that infest and cause disease in fish. The argulids are crustaceans and are related to crabs, lobsters, and shrimp. This 5-page fact sheet was written by Natalie Steckler and Roy P. E. Yanong, and published by the UF Department of Fisheries and Aquatic Sciences, November 2013.

Spring Viremia of Carp (VM142/VM106)

Figure 1. Koi infected with SVCv. Note hemorrhages on body wall.Spring viremia of carp is a viral disease that can cause significant mortality in several carp species including the common carp. It was reported in koi and feral carp in the United States for the first time in 2002. Diagnosis in farm raised fish in the U.S. may result in quarantine of the infected fish and depopulation. This 5-page fact sheet is intended to inform veterinarians, biologists, culturists, and hobbyists about Spring viremia of carp. Written by Barbara D. Petty, Ruth Francis-Floyd, and Roy P.E. Yanong, and published by the UF Department of Fisheries and Aquatic Sciences, August 2012.

Megalocytivirus Infections in Fish, with Emphasis on Ornamental Species (FA182)

Megalocytiviruses cause systemic infections that can result in moderate to heavy losses in many different species of freshwater and marine fishes in both cultured and wild stocks. This 8-page fact sheet was written by Roy P. E. Yanong and Thomas B. Waltzek, and published by the UF Department of Fisheries and Aquatic Sciences, December 2010.

Lymphocystis Disease in Fish (FA181/FA181)

Lymphocystis is a chronic disease of freshwater and marine fishes caused by infection with an iridovirus known as Lymphocystivirus or Lymphocystis disease virus (LCDV). Infection results in the development of pebble or wart-like nodules most commonly seen on the fins, skin, or gills, although other tissues may be affected. This 5-page fact sheet was written by Roy P. E. Yanong, and published by the UF Department of Fisheries and Aquatic Sciences, December 2010.
