Common Catfish Diseases

1. Gill Rot: Gill rot is common in catfish and when it begins, the catfish will practically turn whitish in colour. Most of the time the disease affects their respiratory system which results in weakness leading to inactivities.

 

As a fish farmer, once you notice inactivity and the colour of your fish changing, is an indication that something is wrong. Quickly separate the affected one and start treatment immediately.

 

Note! Gill rot is an infection. That means that when one fish is affected it could be possible that others have been affected too. As you treat the sick ones also administer drugs to the rest of the fish.

 

2. Crack Head Disease: Crackhead disease is common in catfish especially the ones in an earthen pond. This does not mean that catfish in either concrete or tarpaulin pond cannot contract this kind of disease.

 

Other factors that could cause crack disease in catfish are poor water quality due to overfeeding or the accumulation of waste matter. Frequent pond water change will help in reducing the risk of your fish contracting this kind of disease.

 

Crackhead disease arises as a result of deficiency of vital nutrients in fish feed such as Vitamin C, Vitamin D, Calcium, and Phosphorus.

 

Perhaps you formulate feed yourself, make sure that these essential nutrients mentioned are applied in the feed. However, our article on the best catfish feed formula will be a good guide. Otherwise, stick to foreign fish feed.

 

3. Jaundice: It may surprise you to know that jaundice is one of the common diseases found in African catfish. Though mostly found in human beings, especially in newly born babies it exists in catfish as well.

Jaundice disease in catfish is a condition that turns the abdominal region of catfish yellow. This usually occurs as a result of excess bile pigment in the fish’s blood. This kind of disease results in loss of appetite, loss of balance, and an increase in mortality rate due to damage to the cardinal fish.

 

The major cause of this disease is poor water quality and improper stocking (overcrowding).

4. Dropsy Disease: the major cause of dropsy in catfish is kidney failure. It is a bacterial infection that could also be caused by overcrowding. Overstocking makes it easier for disease(s) from one fish to spread to others at a faster rate. The symptom appears in form of bloating and loss of appetite.

 

5. Amenia Disease: In a typical African catfish is one of the common diseases that kill faster. Affected fish is always very black with a big head and tiny bodies just like kwashiorkor.

 

This disease is attributed to overstocking and inadequate feeding. To prevent this from occurring, sort the fish into their different sizes and ensure good quality feeding.

Sign To Look Out For

There are two major or common signs that could be a pointer that something is wrong with the fish stocked. These two factors are:

 

1. Reduced Feed Intake: This happens to be the first sign of many fish diseases. Once there is a drastic reduction in the speed at which the fish rush for food, just have it that something is wrong.

 

 

As a fish farmer, when you notice your fish no long rush for food, the next thing should be to sort them and critically observe to see what could be the cause.

 

2. Abnormal Swimming Pattern: Abnormal swimming pattern could be seen when the fish begin to float on water, jumping, lying flat, robbing themselves against the wall of the pond, moving in a circular pattern and losing balance in the water.

 

The best time to observe these signs is either in the morning or evening during feeding hours. This means that one must have to pay close attention to how the fish behave in the pond at all times.
