Temporal variation in muscle fibre area, gaping, texture, colour and collagen in triploid and diploid Atlantic salmon ( Salmo salar L)
Abstract Diploid and triploid Atlantic salmon were reared for 32 months in seawater, from October 1998 to January 2000. During this period of time, four samplings were taken to study differences in quality traits and chemical components in the flesh between diploid and triploid Atlantic salmon. Seas...
