Effect of temperature on weigth increase, survival, and thermal preference of juvenile redclaw crayfish Cherax quadrecaninatus
The objective was to determine the effect of temperature on the development of Australian crayfish Cherax quadricarinatus juveniles and its thermal preference under laboratory conditions. The determination of the effect ...
Effect of long-term injection of dopamine on the ovarian growth of Cherax quadricarinatus juvenile females (Parastacidae, Decapoda).
The neurotransmitter dopamine (DA) modulates many physiological processes in decapod crustaceans, including reproduction. This study was aimed at evaluating whether the long-term injection of DA affects ovarian growth in ...
Effect of dietary protein and lipid levels on gonadal development of female redclaw crayfish Cherax quadricarinatus
The effect of two crude dietary protein (26% and 32% P) and two lipid levels (4.7% and 12% L) on gonadal development of female redclaw crayfish Cherax quadricarinatus was determined. The gonadosomatic index (GSI), hepatosomatic ...
Growth of redclaw crayfish Cherax quadricarinatus (Von Martens 1868) (Decapoda: Parastacidae) juveniles fed isoproteic diets with partial or total substitution of fish meal by soya bean meal: preliminary study
Growth of juvenile redclaw Cherax quadricarinatus fed 400 g kg)1 crude protein isoproteic diets substituting fish meal with soya bean meal at various levels (250, 500, 750 and 1000 g kg)1) was evaluated under laboratory ...

Effect of dietary protein level on spawning and egg quality of redclaw crayfish Cherax quadricarinatus
The effect of dietary protein level on spawning and egg quality was evaluated for female Cherax quadricarinatus. Diets containing four different levels of crude protein were evaluated (22, 27, 32, and 37%). After 100 days, ...
Effect of dietary protein-to-energy ratio on reproduction in female redclaw crayfish Cherax quadricarinatus
The effect of eight diets with di¡erent protein-to-energy ratios (P-E ratio510, 11, 14, 16, 18, 20, 22, 24mg kJ- 1) on reproduction of female redclaw cray-fish Cherax quadricarinatus was tested under laboratory conditions. ...
Evaluation of practical diets containing different protein levels on gonad development of female redclaw crayfish Cherax quadricarinatus
The effect of five experimental diets with different crude protein content (220, 270, 330, 390 and 450 g kg−1) on gonad development of female Cherax quadricarinatus was tested under laboratory conditions. After 70 days, a ...
