Brook Trout are not genetically programmed to die after spawning as are the Pacific species of salmon. Spawning is however difficult and dangerous and many fish do die during spawning. The length of the incubation period varies according to the temperature - at lower temperatures the incubation period is longer.
More than half of the total length of the German autobahn network has no speed limit, about one third has a permanent limit, and the remaining parts have a temporary or conditional limit. Some cars with very powerful engines can reach speeds of well over 300 km/h (190 mph).

The speed limit on a dual carriageway or motorway is 70 mph for cars and motorcycles, unless there are signs to indicate otherwise. The speed limits for different types of vehicles are listed in The Highway Code.hey may have to use the other side of the road, and if you park near the brow of a hill, they may not be able to see oncoming traffic.
