Insight on some Common Fish Diseases

Bacteria are a common cause of problems for fish farmers. Many bacterial diseases of fish caused due to pathogenic bacteria. These bacteria can attack both externally on the fish, or can the body of the fish through the skin and can damage internal organs, even leading to death. Bacterial gill disease and fin rot is the most common bacterial attack fish with fins and gills infected respectively. If the bacteria have managed to gain access to the body, it is known as systemic infection. Bacteria can also cause ulcers and sores on the body of the fish. Bacterial infections are easily visible from the outside, as ulcerative redness or irritation on the skin of fish. Bacterial infections are common in koi fish.

Lice Fish - Fish lice are known scientifically as Argulus, and about an inch in size, they are among the largest found in the animal parasites. They are very harmful to the health of fish, because they absorb moisture from the body of fluids through their trunks when the terminal mouth in the organs of the fish.

Lice are easy to identify the bodies of the fish because they are clearly visible. However, it is necessary to a thorough inspection of the body of the fish to wear, especially in hidden areas behind the fins. Lice can appear as dark spots when they are not moving. If too many lice, the fish is very excited and want to move their body a lot.

Fishbones - Flukes are parasites of fish that is harmless in small quantities but can be fatal for the fish in large numbers. Tail fins are small, about 2 mm long, and is almost invisible to the unaided human eye. But these bones have hooks so they clamp to the bodies of fish. Bones can absorb body fluids of fish and even cause death. The great danger of bone, is a coincidence that only one fish had to complete its life cycle, and therefore there is more reason why Fluke remain clamped on the fish. Tail fins were considered the hardest of the fish parasite treatment, although treatment with malachite and formalin often show positive results in stronger doses.

Ich - better known as ich or Ichthyobodo Costia is a common parasite that is found on the bodies of fish. Different fish can live with this parasite is no evidence whatsoever. In fact, in a small number of ich is harmless. Defenders of the fish can keep control of ich. But when the fish are suffering from another illness, the defense broke and then begin to multiply ich. Ich can multiply at a rapid pace. At no time will the fish show a large amount of ich on his body, breathing becomes difficult and short, it will withdraw and isolate themselves from other fish. When that time comes, ich appears often fatal to fish.
