Flesh color of gold (homozygous rccessive gg), bronze (heterozygous flesh and peritoneal lining color in gold, bronze and black T.
Gg), and black (homozygous dominant GG) Tilapio mossambica was
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.
