Capturing this summer, even if the 'atmosphere and' Autumn .. (Thanks to Andoni for the photo despite the foul weather)
Halloween and 'just passed and the waters are cooling. It 'a good time to fish for pike and it' s also a good time for pike.
Why '?
There 's never happened to see or get yourself a pike with rosy monstrous growths, often bloody, on the head or on the skin? When you've got?
Have you ever caught one so 'in the summer / winter?
Let's give an answer to each of these questions. And something more '.
nose and I'm going to bet, sure not to miss the most 'that much, that if you have never seen a pike with these growths is not' state in the winter.
But we do not bite off more than 'chew: What are these growths?
They are nothing but cancer, fleshy growth and well-perfused blood vessels as virtually all cancers. They are usually defined as lymphoma or lymphosarcoma in what seems to be developed primarily by a degeneration of the lymph nodes or other lymphatic system and tumors are very common in pike.
localization more 'typical textbook, and' referred to as the rear two-thirds of the body.
Actually 'and' a cancer that you can 'show virtually anywhere in the body, even in areas not obviously linked to the lymphatic system as a sarcomatous.

Lately indeed not 'rare to find mainly on the front of the body, near the mouth in particular. The thing
'anything but' proven but because most 'probable' that is due to increasing popularity 'of the catch and release. The tumor was in fact probably (an educated guess at the moment is not fully tested) based on viral and wounds caused by the hooks are good access roads.
The structure of these tumors and a 'very simple: a mass of tissue cells that grow without a generic organizational structure and are fed largely from host tissue by a dense network of capillaries. In addition to the viral cause cancer spreads in the population through the rupture of this tissue and the penetration of cell-free wounds.
The care and 'the prince in time where you exchange this contagion.
Given the mode 'of dissemination should not be surprising that the incidence of this tumor and' more than 20% in some populations of pike. A record in the animal world.
But 'cause I've never seen one? You say ..
Probably 'cause some people are more' affected than others and some are not affected. But above all, perhaps because 'caught mainly from autumn to spring, it thrives in the summer for lymphosarcoma then fall dramatically and disappear quietly when the water cools. Although once infected lymphosarcoma continue 'to grow each season, in the same place, as soon as conditions become favorable. Some authors have suggested that unlike the tumor withdraws during the hot season because of high temperatures, personally (and the photo above it and 'one of the tests) I have always found the opposite.
There 's also another factor, pike lymphosarcoma with a beautiful pink and lost all its obvious characteristics of camouflage and is normally preyed upon, not to mention all the cases in which it becomes a real impediment to nutrition and predation.

There 'to say but' which is' essentially a benign tumor, which does not kill the pike will 'directly will' in the long run. The pike with this disease remain healthy and strong, well, eat normally and live well after all.
not have much luck but 'the muskie that where populations overlap, are infected during the care and die, because for them, and' life threatening infection.
In general, however, 'there is no way to remove an infected sample, even though the meat still edible and the infection does not transmitted to humans, 'cause all in all we do not change one iota the incidence of disease in the population.
And then, frankly, would you dare to eat a fish like that?
