Originating in North America, the catfish is well established in France and this since 1950. In the beginning, it would be escaped aquariums of the Natural history museum of natural history in Paris to colonize the Seine, via the sewers.
Lifestyle
The catfish attends lukewarm water of the ponds, channels and of the gravel pits. One also finds it in calm water of the rivers and rivers. Particularly resistant and supporting the lack of oxygen, the catfish can in period of dryness. It can be acclimatized perfectly in a warm water to 36°C. The catfish lives posed on the content, in groups sometimes very important. Its activity is primarily night. The body of the catfish, covered with thousands of sensory airframes is a characteristic of the species. Many authors describe the existence of a particularly elaborate chemical which controls the social relations within a group.
The laying intervenes in water of approximately 20°C. The nest prepared by the female accommodates the eggs which will be defended by the couple in an aggressive way. Incubation will be of ten days and to the blossoming the alevins

Fish
Vermin, its eradication is recommended
Its fisheries are practiced with the floating line or with leaded. The resting at the bottom consists of earthworms means. It also attacks sharp. A cane with the blow, to 6 to eters is enough. Avoid the basket and preserve the captures in a bucket; it is useless to risk the punctures unnecessarily.
Use a conventional line, balanced well (only the antenna exceeds). The yarn is into 12/100, the bottom of line into 10/100, without forget small shot of key to 10 cm of the hook to 12. As starts, of the dried and crushed bread will make the deal. To wet with a product containing fish. To make boil a fish of quite fatty sea (mackerel, whiting etc) and recover water.
Another solution: To add pellets for trout. They are containing fish meals and are thus appropriate perfectly. Add argillaceous ground to form balls which the fish will explode more or less quickly. As a soft food, think of the maggots… or peeled shrimp tails.
