“…Camarões desta espécie geralmente apresentam grande porte, altas taxas de fertilidade e fecundidade, podendo ultrapassar 17.000 ovos por fêmea (Valenti, Mello & Lobão, 1989;Albertoni, Palma-Silva & Esteves, 2002;Tamburus, Mossolin & Mantelatto, 2012). É de fácil manutenção e reprodução em cativeiro (Choudhury, 1970;New, 1995;Gomes, 2009).…”

Macrobrachium acanthurus apresenta ampla distribuição e é abundante nos rios em que ocorre, possuindo subpopulações com grande número de indivíduos. Há indícios de declínio pontual em populações do nordeste e do estado do Rio de Janeiro. Entre os camarões do gênero Macrobrachium, M. acanthurus destaca-se pelo alto potencial para exploração em escala comercial e também pelo extrativismo por comunidades ribeirinhas. Apesar de sofrer impactos pela poluição, supressão das matas ciliares, despejo de esgoto, lixo e agrotóxicos em estuários e ambientes de água doce, em algumas localidades de sua distribuição, estas não representam risco de extinção para a espécie no futuro próximo. Desta forma, a espécie foi categorizada como Menos Preocupante (LC).

The cinnamon river shrimp (Macrobrachium acanthurus) is distributed along the Atlantic Ocean, from the United States to Brazil. This species represents important resources for local communities of fishermen, but natural populations are facing a progressive decline. For several years, the aquaculture supplementation of this species has been suggested as an alternative to fisheries. M. acanthurus presents several characteristics that make it a suitable species for aquaculture, such as resistance to changes in environmental conditions, reproduction all year round, high fecundity, low aggressivity, and disease resistance. Despite this, the development of culture is, at best, at the stage of research and has been related to the difficulty of the larval stage rearing. Considering this, the review presents the actual knowledge regarding the environmental and biological conditions of M. acanthurus that might help to advance its culture. The information is presented in several parts, which include the species description, environmental conditions, reproduction, larvae and juvenile stages, culture experience, and diseases. Finally, some considerations are given to cover the gaps in the knowledge that are required to be researched.

Pseudopalaemon bouvieri undergoes complete abbreviated development. The reproductive cycle (proportion and size of the sexually mature population and juvenile recruitment), fecundity and egg size of this prawn were examined in three subtropical shallow lakes. The reproductive cycle was seasonal; gonadal maturation occurred during the winter, ovigerous females were abundant in the spring and breeding occurred at the end of spring. Females produced small numbers of eggs (9-55) of relatively large sizes (1.0-2.1 mm). The proportion of ovigerous females with respect to the total number of females, the fecundity and egg size differed among the lakes according to the trophic state of the environments. Pseudopalaemon bouvieri has a reproductive strategy similar to other Palaemonidae species that inhabit nutrient-poor inland waters. RESUMENPseudopalaemon bouvieri tiene un desarrollo completamente abreviado. Fueron examinados el ciclo reproductivo (proporción y tamaño de la población sexualmente madura y el reclutamiento de los juveniles), la fecundidad y el tamaño de los huevos de este camarón en tres lagos subtropicales poco profundos. El ciclo reproductivo fue estacional; la maduración gonadal ocurrió durante el invierno, las hembras ovígeras fueron abundantes en primavera y las crías aparecieron a finales de la primavera. Las hembras producen un bajo número de huevos (9 -55) de tamaño relativamente grande (1,0 -2,1 mm). La proporción de hembras ovígeras con respecto al número total de hembras, fecundidad y el tamaño de los huevos difirieron entre los lagos, de acuerdo al estado trófico de los ambientes. Pseudopalaemon bouvieri tiene una estrategia reproductiva similar a otros Palaemonidae que habitan ambientes acuáticos continentales pobres en nutrientes.

Populational and reproductive aspects of Southern <i>Macrobrachium acanthurus</i> (Wiegmann, 1836) (Crustacea: Palaemonidae), Brazil

Abstract: The absence of embryo loss during the incubation process may be speculated to be an efficient strategy developed by the ovigerous females, as a mechanism of parental care against the most common causes of egg loss.
