Strong starvation resistance has been observed in larval decapods developing in freshwater where food appearance may be unpredictable or poor. The point-of-no-return (PNR) has often been utilized to quantify the vulnerability of a given species or developmental stage to starvation. Most studies of nutritional effects on decapods focus on marine species, while there is less information on freshwater species. We evaluated the effects of starvation on survival, growth, and hepatopancreas structure of both early (first free-living stage, JIII) and late (1 g, J1g) juveniles of Cherax quadricarinatus. The experiments consisted of treatments with increasing numbers of days without food followed by continuous feeding until Day 60 (experiment with JIII) or 90 (experiment with J1g). Regardless of body size, the time from the beginning of the experiment to first ecdysis increased with the length of the starvation period. Growth was affected by starvation in JIII, but it recovered after feeding, while growth could not be fully compensated during subsequent feeding in J1g. PNR values (means ± SD) were 8.7 ± 0.3 and 51.0 ± 1.5 d, corresponding to 125 and 220% of total stage duration, respectively. In conclusion, juvenile C. quadricarinatus are highly resistant to starvation compared to early stages of other decapods. Freshwater environments with unstable conditions of food availability may have selected for strong starvation resistance, i.e. low nutritional vulnerability. This feature gives this species potential importance for aquaculture and as an invader.

Hence, the capability of a decapod to survive transitory lack of food and to subsequently recover from such periods depends on adaptive physiological and behavioral traits and, especially, on its capacity to store energy in the hepatopancreas.All these properties vary greatly among phylogenetic groups, developmental stages, reproductive periods, and adult habitats (Sulkin & McKeen 1999, Giménez & Anger 2005, Calado et al. 2010. A particularly strong starvation resistance has been observed in larval decapods developing in freshwater, at high latitudes, or in other highly variable habitats, where food availability may be unpredictable or on average poor (e.g. Anger et al. 2004, Paschke et al. 2004. Most studies of nutritional effects on decapods, however, focus on marine species (e.g. Liddy et al. 2003, Bas et al. 2008, Zhang et al. 2009, Gebauer et al. 2010, while less have been carried out on freshwater species (Jones & Obst 2000, Anger & Hayd 2009, Powell & Watts 2010.Using larvae of the spider crab Hyas araneus as a model, Anger & Dawi...

At stage 3, juveniles became independent (Levi et al 1999) and were separated from 6 mothers, then pooled and maintained under the same conditions mentioned above (based on previous studies; Vazquez et al 2008, Stumpf et al 2010, Tropea et al 2010, Calvo et al 2013) until they reached the desired weight.…”

RESUMEN.Se analiza en juveniles en etapa de engorde (7 g) de Cherax quadricarinatus, el ritmo circadiano de los niveles de proteínas totales, la actividad de las proteasas, lipasas y amilasas, y su posible modificación en función del momento de alimentación matutino (8 h) y vespertino (17 h). En general, la actividad de las enzimas digestivas de los juveniles de C. quadricarinatus no mostró un patrón circadiano de secreción, a excepción de las lipasas, donde se observó un incremento de actividad hacia la tarde-noche y disminución hacia las primeras horas de la mañana. Los niveles de proteína total, la actividad de proteinasas y amilasas registradas en la glándula digestiva, permanecieron prácticamente inalterados en todos los experimentos. A pesar de ello, se observó tendencia a que los niveles de actividad de proteinasas disminuyan luego del pulso de alimentación, recuperando los niveles anteriores 3 h después, independientemente del horario de alimentación. En cambio la actividad de amilasa no mostró ninguna tendencia por efecto del horario de alimentación. El estudio de los patrones de secreción de las enzimas digestivas y sus posibles modificaciones, podría ser utilizado como una herramienta para establecer los momentos del día más propicios para la alimentación de los juveniles en cultivo.

Influence of feeding on the circadian rhythm of digestive enzymes in cultivated juveniles of the freshwater crayfish Cherax quadricarinatus (Parastacidae)ABSTRACT. We analyze in juvenile Cherax quadricarinatus fattening stage, the circadian rhythm of total protein levels, activity of proteases, lipases and amylases, and their possible change as a function of morning (8 h) and evening (17 h) feeding. In general, the activity of digestive enzymes of juvenile C. quadricarinatus showed no circadian pattern of secretion of lipases except where there was an increase towards the evening-night and a decrease towards the early hours of the morning. The total protein levels, the activity of proteinases and amylases of juveniles of C. quadricarinatus registered in the midgut gland remained virtually unchanged in all experiments. However, a non-significant tendency to diminish the proteinase activity levels after the feeding pulse was observed, with a return to previous enzymatic levels after 3 h. In contrast, the amylase activity did not show an observable effect by the feeding schedule. The study of the patterns of the digestive enzyme secretion and their possible changes, could be used as a tool to establish the most favorable times of the day for juveniles feeding.
