Protease activities in the digestive tract and carotenoid levels
in flesh, ovaries and plasma were determined in 4 to 4 1/2 year
old Atlantic salmon (Salmo salar) during the period from early
March until December. The protease activities in the digestive tissue significantly
changed during the maturation process. The sexual maturation
significantly decreased the level of astaxanthin in the flesh
and ovaries, but the total amount in the ovaries still increased.
The covariance between astaxanthin in plasma and tryptic-like
activities in the digestive tissues were significant, and the
level of astaxanthin in plasma was also influenced by time and
stage of sexual maturation.
