Implantation
The Boom is an Eurasian species with a very vast distribution in the northern hemisphere. It is adapted perfectly to the seasonal changes of the moderate climates. She appreciates a water around 25°C. Indigenous in the north of France, the Boom was established in the south and the west of France by using the channels.
Lifestyle
This attends water with moderate current as well as stagnant water of the ponds and the lakes. The offering funds of the shelters such as stocks or rocks, are appropriate to him perfectly, not without forgetting some herbaria.
The Boom is nourished of worms, shellfish, larvae of insects but it is also a predator. Its food activity is rather diurnal with a point of appetite at dawn and the twilight. It is generally in summer that this food activity is highest. Young person, the boom drives out in group, hidden in the watery plants. The first victim will be the small fish on which it will melt by behind into corrosive the tail. While growing, its mouth becomes of a beautiful size which enables him to take without evil of small fish, there understood small booms.

Incubation lasts approximately 15 days in ones water with 13°C. In addition to the pike which is its predator, the Roach likes to him to come to steal eggs deposited in ribbon the grasses. By taking a large specimen (g it is already a beautiful capture), there are good lucks find another very meadows of them. The booms live in group of age. Progressively, these groups become less important at the point to make tell than largest live as a recluse!
In summer one finds it close to the edge, in herbaria or dissimulated immersed wood meadows. The winter seek rather in the great depths.
Fish
The boom can be fished with sharp, death handled, the decoy. For the fisheries to be ground with the spoon, a cane of 2, equipped with a fixed drum winch will make the deal. A yarn of 20/100 will make it possible to follow the management of the departures well. The bottom of line will be to mount on swivel with in end fasteners to be able to change spoon easily.
