We examined the effect of the double restriction-recovery cycle on survival, growth, and nutritional status of the freshwater prawn Macrobrachium borellii (Nobili, 1896), native to floodplain rivers of Argentina. The restriction period consisted of intermittent starvation (alternating four-day feeding with no feeding for four days) and a recovery period of continuous feeding following the restriction period. Survival was high over a 20-week trial with cycles of food scarcity. Prawns showed a slight impact on their growth throughout the entire first cycle of restriction-recovery; however, compensatory growth was not triggered. The reduction of growth was markedly more drastic after the second restriction period, but compensatory growth was not exhibited when the second recovery period was reestablished. Any possible impact of the double cycle of intermittent starvation on energy reserves and structure of the hepatopancreas was compensated by a posterior cycle of continuous feeding. The results demonstrated that M. borelli can successfully support long-term food scarcity throughout the juvenile and adult phases, at least intermittently and followed by a recovery period. The high nutritional flexibility is an adaptation to fluctuations in food availability and an advantage for successful ornamental aquaculture.

间歇饥饿对淡水虾Macrobrachium tubellii Nobili的存活，生长和营养状况的影响，1896年（十足目：Caridea：Palaemonidae）

我们研究了双重限制回收周期对淡水虾Macrobrachium tubellii（）的存活，生长和营养状况的影响。Nobili，1896年），原产于阿根廷洪泛区河流。禁食期包括间歇性饥饿（每隔四天喂食一次，四天不喂食）和限制期后连续喂食的恢复期。在长达20周的试验中，由于食物短缺，存活率很高。在限制恢复的整个第一个周期中，大虾对其生长均显示出轻微的影响。但是，补偿性增长并未触发。在第二个限制期之后，生长的减少明显更加剧烈，但是在恢复第二个恢复期时，没有表现出代偿性生长。间歇性饥饿的双周期对肝胰脏能量储备和结构的任何可能影响都可以通过连续进食的后周期来补偿。博雷利杆菌可以成功地支持整个幼年和成年阶段的长期食物短缺，至少是间歇性地，然后是恢复期。营养灵活性高，可适应粮食供应的波动，是成功进行观赏性水产养殖的优势。
