Hi gang,
Columnaris. Diquat was the best treatment in the study I read. More later.
C) This is a highly communicable disease. Lesions usually first appear
on the caudal fin and progresses towards the head. The caudal fin and
anal fins are severely eroded. As the disease progresses the skin is
often involved with numerous gray-white ulcers. Gills are a common site
of damage and may be the only affected area. The gill lesions are
characterized by necrosis of the distal end of the gill filament which
progresses basally to involve the entire filament.
D) Flexibacter columnaris infections are frequently associated with
stress conditions. Predisposing factors for columnaris disease are high
water temperature (25oC-32oC.), (77-89.6F),crowding, injury, and poor water
quality
(low oxygen).
