Like chondrostean fish, the major immune tissues of bony fish (or teleostei) include the kidney (especially the anterior kidney), which houses many different immune cells. [57] In addition, teleost fish possess a thymus, spleen and scattered immune areas within mucosal tissues (e.g. in the skin, gills, gut and gonads).

[2] This fish has an overall dusky orange to red colour with white markings. The dorsal fin appears feathery while rest of fins have black margins. [3]

As the name implies, it causes severe anemia of infected fish. Unlike mammals, the red blood cells of fish have DNA, and can become infected with viruses. The fish develop pale gills, and may swim close to the water surface, gulping for air. However, the disease can also develop without the fish showing any external signs of illness, the fish ...
An effective way to clear Ich from a fish population is to transfer all of the fish carrying trophonts in their skin, fins or gills to a non-infected tank every 24 hours. Then the fish do not get re-infected and after a number of days (dependent on temperature) the fish have cleared the infection because trophonts exit within this period.
Fish allergy is an immune hypersensitivity to proteins found in fish.Symptoms can be either rapid or gradual in onset. The latter can take hours to days to appear. The former may include anaphylaxis, a potentially life-threatening condition which requires treatment with epinephrine.
