Gill Disease of Pond Cultured Eeles.

Atlantic salmon (Salmo salar L.) exposed to cultured gill-derived Neoparamoeba branchiphila fail to develop amoebic gill disease (AGD)

Gill-derived Neoparamoeba spp. from Atlantic salmon cause amoebic gill disease (AGD) in naïve recipients. Atlantic salmon were inoculated with clonal gill-derived Neoparamoeba branchiphila that had been cultured in the presence or absence of Atlantic salmon cutaneous mucus. Neoparamoeba branchiphila did not elicit AGD and the supplementation of cultures with cutaneous mucus did not influence vi...

Proliferative Gill Disease (Hamburger Disease)

has become common in farmraised channel catfish. It can kill a few dozen fish over several days, or up to 100 percent of the fish in less than 3 days. Recurrence in the same pond is rare. From 1991 to 1995 PGD was the fourth most commonly diagnosed disease of catfish in the southeastern U. S., occurring in one out of every ten disease cases. This disease causes catfish to suffocate because of t...

Bacterial Gill Disease

Bacterial gill disease (BGD) is a common external infection of hatcheryreared salmonids and occasionally of warm water species reared under intensive conditions. As defined by Wood (1974), the name of the disease describes the clinical signs of bacterial infections on the gills. The etiological agent of the disease is considered to be one or more species of filamentous bacteria including Flavob...
