Abstract
Reproductive parameters (number of eggs, fertility index, survival of
juveniles) and the biochemical composition (proteins, carbohydrates, lipids)
of Cherax quadricarinatus broodstock were examined in specimens with weights
ranging from: (i) 30-45; (ii) 46-60; (iii) 61-75g; (iv) 76-90 g, in an
intensive system (4 organisms/m2) with zero-water exchange (maintained at
28+1?C and aerated continuously). Better reproductive efficiency was observed
in specimens with smaller weights. This effect was also reflected in the
biochemical parameters of the eggs and juveniles. The use of broodstock whose
weight ranges between 45 and 60g is recommended.
