Yea it is! I thought it looked like Salmon flesh as well. Sort of red orange? I know the meat in the Carp I've caught and cut up for Blue Cat bait is always a pale pinkish color with a red blood-vein, or what some people call a mud-line through the middle of the flesh.
The fella on the filleting video said the Carp he catches come from clear water and feed heavily on Crayfish & seeds. I did some searching on the inter-web and found some interesting information on the subject.
1.From the Nanfa Website:"All species of fish can vary in color depending on local strain, morph, or varient. Water conditions such as temperature, turbidity, PH, acidity & hardness also play a role in the coloration & health of all fish. Time of year & type of food they're feeding on influences coloration as well. High levels of carotenoids found in shrimp, crayfish, & blue-green algaes enhance yellow, orange, & red colors in fish."
2.Article from the nytimes:What Determines the Color of Fish Flesh?"Diet can contribute to a red flesh color in fish. Fish with orange flesh have generally been feeding heavily on ocean crustaceans like krill, which contain pigments called carotenoids, Dr. Tidball said. He listed other dietary sources for color, like freshwater crustaceans and possibly terrestrial insects."

"Unlike beef, which acquires its distinct red hue from contact with oxygen in the air, salmon meat gains its color through the fishs diet. Out in the ocean, salmon eat lots of small free-floating crustaceans, such as tiny shrimp. These crustaceans are filled with molecules called carotenoids, which show up as pigments all over the tree of life. In fact, if youve ever known a kid who turned orange from eating too many carrots, youve seen carotenoids in action. Its these carotenoids that account for the reddish color of the salmon, as well as the pink color of flamingoes and the red of a boiled lobster. Farmed salmon, however, arent fed crustaceans. Instead, they eat dry pellets that look like dog food."
