Diagnosis: page 8 Treatment: page 28 This disease frequently occurs in case of poor hygienic conditions and overstocking. These bac- teria, small numbers of which are also present in the tank otherwise, be- come a serious threat only under such conditions. 6.2 Treating bacterial diseases Fin rot in its final stage Bacterial gill rot Diagnosis: page 8 Treatment: page 28 Diagnosis: page 9 Long lasting stress situations, e.g. strongly or- ganically polluted water, weaken the immune system of the fish, making the organism vul- nerable for bacterial infections. Often, only a few of the fish are affected. The disease usu- ally begins with a bacterial infection of the in- testines. However, it can also occur as a final stage symptom of various other diseases. The infection of the intestines becomes visible by the excretion of slimy fish waste. During the further course the intestinal mucous mem- brane begins to decompose (it comes off as white slime threads). Nutrition taken up cannot be digested any more. The damaged intestinal mucous membrane has become penetrable for pathogens, leading to other organs being infected or degenerating due to lacking nutri- ents in this stage. When finally the kidney function is affected, unexcreted liquid accu- mulates in the body cavity (bloated belly), in Dropsy Aeromonas or Pseudomonas bacteria Diagnosis: page 9 Treatment: page 28 the scale pockets (protruding scales) or at the background of the eyes (exophthalmus). Addi- tional swimming bladder infections usually lead to abnormal swimming behavior. Fish showing these symptoms can often not be saved any more. An extensive treatment with the above men- tioned treatments must be carried out if only one of these symptoms is observed. It is ideal to put the affected fish, which excrete plenty of pathogens, into a quarantine tank and use a combination of the three sera baktopur preparations. You should also treat the main tank with, for instance, sera baktopur after you have removed the conspicuous fish, as to reliably prevent the disease from spreading. Be sure to maintain proper water quality in any case. Fin rot 29
