Spring Viremia of Carp

What is Spring Viremia of Carp?
Spring viremia of carp is cause by an RNA virus.





Signs of SVC:
-Darkening of skin
-Pop eye
-Hemorrhages in the gills, skin, and eye
-Inflammation
-Pinpoint hemorrhages in the swim bladder
-Concurrent infection with bacteria
-Decreased respiration rate
-Loss of equilibrium

Treatment:

There are no antiviral drugs to treat SVC. Manipulating temperature is the most practical means of preventing of controlling mortality. Keeping the water temperature above 20*C (68*F) may help contribute to prevent a potention outbreak. Fish exposed to stressors become more likely to contract the virus due to immune system suppression.

Swimmer's Gill

What makes fish gills more problematic than then rest of the body is that we can't really see what is going on. Many times, when you can tell that the fish is sick, the damage is too advanced that it is untreatable. In turn, early diagnosis and treatment is key.

Signs of gill trouble:

-Fish respiring heavily. Judge this by comparing the movement with other fish.

-Fish laying on the bottom of ponds for long periods, not eating.

-Fish only using one gill, keeping the other against its body.

-Affected fish segregating itself and staying alone near the surface.

-Strands of mucus trailing from the gills.

-Fish laying on the bottom of the pond with both fins clamped to side.

Treatments:

-Most gill diseases can be avoided with good water management practices.

-Check your pond water for ammonia, nitrite, pH.

-If several fish are affected, somewhere between 50-75% of the water should be changed.

-Examine your fish for parasites.

-In advanced stages, the chances of survival is not good. Prevention is the best way to make sure your fish are safe.

Fin Rot

What is Fin Rot?

Fin Rot is a term used for loss of fin tissue, resulting in split or ragged fins. It is usually the edge of the fin that is attacked, although sometimes a hole in the middle of the fin may occur. The edge of the lesion is usually opaque or whitish. In advanced stages, the fin may experience some reddening or inflammation. If left untreated, fin rot can slowly eat away at the entire fin and make its way up to the fish's body.

Causes:

Fin rot is most frequently caused by stress, fear, or poor environmental conditions. It is usually self-resolving, but it does show how sensitive fish can be to stress.

Treatment:

The stress fish experience can be due to parasites, overcrowding, low oxygen, bullying, poor water quality, and other aspects of your pond that can effect your fish. If the stressor is caught, it might be sufficient enough to stop fin rot. In more advanced stages, it may be necessary to trim and remove the affected tissue. This will need to be done when the fish is sedated. In minor cases, the fin will most likely grow back.

Bacterial Ulcers

Bacterial ulcers can be one of the most difficult Koi Fish problems to handle. Effectively treating the ulcers can take a lot of time and experience. However, the success rate can be very high, unlike bacterial gill diseases.

What is an ulcer?

An ulcer is a break in the skin extending through all the layers and is usually accompanied by inflammation. Without treatment, the ulcer slowly gets bigger. Many times, it is caused by opportunistic bacteria already in the pond or tank.

Causes:

Ulcers can be caused by damage to the skin from parasites or chemiclas or from trama caused by breeding efforts or handling. If only one fish is affected, a health issue specific to that individual is probably the cause. If several fish are affected, there is likely an environmental issue. It is very important to establish the underlying cause to be able to effectively treat the bacterial infection.

Treatment:

It is hard to give a general treatment for bacterial ulcers because it really depends on the specific environment and circumstances of each case. If several fish are affected, it is important that they are examined to determine the full extent and spread of the infection. It is important that all of the infected fish are treated at the same time, otherwise, the untreated fish will continue to get worse and act as a reservoir of infection. Treatment can be in topical treatments, medicated food, bath treatments, or antibiotic injections. The aim should be to resolve the problem in 2-3 weeks. If there is not marked improvement during this time, the treatment plan needs to be reevaluated.
