Western Chemical is the exclusive distributor of HALAMID® (Chloramine-T) for use in Aquaculture and it ships from various warehouses to allow for cost effective shipping throughout the United States. 

Chloramine-T has been widely used to successfully control mortality in fishes diagnosed with Bacterial Gill Disease (BGD) and external flavobacteriosis.

HALAMID® (Chloramine-T) is currently available for use under FDA INAD # 9321 and must be used according to the FDA's guidelines for Investigational New Animal Drug Application (INAD).  More information including INAD application forms, study protocols, study summaries, etc can be obtained from the U.S. Fish & Wildlife Service's office of Aquatic Animal Drug Approval Partnership Program (AADAP).  The AADAP office has streamlined the INAD process and the staff there are very helpful.

Bacterial gill disease (BGD), caused by Flavobacteria branchiophilum and other external flavobacteria, is a potentially acute disease of intensively cultured fish, particularly young salmonids. If BGD is not diagnosed and treated early, epizootics may occur within a 24 hour period. External flavobacteria, caused by F. columnare, F. psychrophilum, and other closely related yellow-pigmented gliding bacteria are often collectively termed “external flavobacteriosis” and are chronic to acute diseases that have been reported in many species of cultured cold-, cool-, and warmwater fish. External flavobacteriosis and BGD may occur at a wide range of water temperatures.

Chloramine-T has been widely used to successfully control mortality in fishes diagnosed with Bacterial Gill Disease (BGD) and external flavobacteriosis. The primary goal of field studies conducted under INAD #9321 is to generate additional data to help demonstrate the efficacy of Chloramine-T to control mortality in a variety of fishes diagnosed with Bacterial Gill Disease (BGD) or external flavobacteriosis.  Once approved by the FDA, Chloramine-T will no longer be available under an INAD and the only legal source will be the sponsor of the approved product. The standard treatment regimen for the control of mortality caused by Bacterial Gill Disease (BGD) or external flavobacteriosis is a 1 hour static bath or flow through Chloramine-T treatment. Chloramine-T may be administered at 10, 15, or 20 mg/L Chloramine-T, and fish may be treated 1 - 3 times on alternate or consecutive days. For more details about the various treatment options available under INAD #9321, refer to the protocol. Regardless of the treatment option used, fish may be slaughtered for harvest or stocked immediately after treatment.
