Day 6: our last day of this short roadtrip. We arrived in Bergen and decided to go to the fish market and eat some Kings crab. Red king crabs can be very large, reaching a leg span of 1.8 m and weight up to 15 kg. The living animals have a brown-burgundy color, the red color results from being cooked.The king crab was introduced artificially by the Soviet Union into the Murmansk Fjord during the 1960s to provide new, valuable catch for Soviet fishermen.In the North Sea it is an invasive species and its population is increasing tremendously. it has spread westwards along the Norwegian coast and also northwards up to Svalbard. The average temperature of the water for general survival of the crab is between 4°C and 10°C.
