Flesh and Peritoneal Lining Color of Gold, Bronze, and Black Tilapia mossambica

摘要

ABSTRACTFlesh color of gold (homozygous recessivegg), bronze (heterozygousGg), and black (homozygous dominantGG)Tilapia mossambicawas evaluated sensorily (visually). Gold fish had white flesh, while black and bronze fish had flesh that had a grayish tint. Flesh color of gold fish was significantly lighter than that of both black and bronze fish (P = 0.001). Flesh color of bronze and black fish did not differ. Peritoneal lining of the abdominal cavity of black fish is black, that of gold fish is white, and that of bronze fish is spotted and quite variable. The peritoneal lining of black fish must be removed when they are marketed whole to remove the black pigmentation, but this is not necessary with gold fish.
