Crayfish fed pectin containing
pellets exhibited a significant weight gain. Digestive enzyme activities did not statistically show significant
differences in the digestive tract except for amylase that was significantly higher in the intestine of animals
fed pectin containing pellets. Our data indicate that pectin and chitosan pellets showed the best water stability
performances, moreover pectin pellets brought about the highest body weight gain and affected the amylase
profile in the intestine of juvenile Cherax albidus.
