“…From previous research with prawn larvae (Anger, 2001;Anger et al, 2009), it is known that physiological and anatomical differences between stages affect survival, particularly their ability to eat during the first three stages, when physiological readjustments require additional energy (Agard, 1999). Recently-hatched larvae still have yolk, which enables them to survive one or two molts without feeding (García-Guerrero & Hendrick, 2009).…”

ABSTRACT. The cauque river prawn Macrobrachium americanum occurs along the Pacific coast of America. This prawn can grow to a large size, making it an interesting option for aquaculture production. Currently, supplies of juveniles are limited because hatchery and laboratory-reared larvae are difficult to raise. This study assesses larval survival for different combinations of stocking density and feeding from larvae cultivated in green water. From these combinations, larvae fed with Artemia nauplii and maintained at a density of 50 larvae L -1 had the highest survival.Keywords: Macrobrachium americanum, larval development, feeding, survival, prawn.Cultivo experimental de larvas de langostino Macrobrachium americanum (Bate, 1868), con énfasis en alimentación y efecto de la densidad sobre la supervivencia RESUMEN. El langostino de río Macrobrachium americanum, ocurre a lo largo de la costa Pacífica de América. Este langostino puede alcanzar grandes tallas lo que lo convierte en una opción interesante para la acuicultura. En la actualidad, el abastecimiento de juveniles a partir del cultivo de sus larvas en hatchery y en laboratorio son difíciles de criar. Este estudio evalúa la supervivencia de las larvas con diferentes combinaciones de alimento y densidades de población cultivadas en agua verde. A partir de estas combinaciones, las larvas alimentadas con nauplios de Artemia salina, mantenidas a una densidad de 50 larvas L -1 , tuvieron la mayor supervivencia.Palabras clave: Macrobrachium americanum, desarrollo larvario, alimentación, supervivencia, langostino.

“…In January 2006, 15 shrimps were transported in cooling boxes to the Helgoland Marine Biological Laboratory (BAH), Germany. Here, they were subsequently maintained in individual, aerated, flow-through aquaria with 30 l freshwater (total ion concentration: 0.2 mg l -1 ), constant 29°C and a 12:12 h light:dark cycle (Anger et al 2009). Pieces of frozen marine isopods (Idotea spp.)…”

“…In contrast to numerous other freshwater-inhabiting congeners, which pass through an abbreviated mode of development (Murphy & Austin 2005), Macrobrachium amazonicum has an extended larval development through 9 to 11 stages, similar to those in most estuarine and marine relatives (Guest 1979, Vega Perez 1984, Magalhães 1985, Anger et al 2009). In populations living in coastal rivers and adjacent estuaries, the larvae require for successful development a low or moderate salt concentration (Guest & Durocher 1979, Lobão et al 1987, Rojas et al 1990, Araujo & Valenti 2007.…”

“…Thus, previous studies also could not rule out the possibility that larval feeding might actually begin even earlier, before the end of the first zoeal moulting cycle. Furthermore, intraspecific variability in larval biomass at hatching (Anger et al 2009) may cause variation in the endotrophic potential and, as a consequence, in the onset of feeding in larvae produced by different females.…”

During downstream transport from rivers to estuaries, early larval stages of the Amazon River prawn Macrobrachium amazonicum (Heller 1862) are likely exposed to planktonic food limitation. In the laboratory, we studied the effects of presence or absence of food on larval survival, moulting and biomass (dry mass, and content of carbon, hydrogen and nitrogen). Unfed larvae developed successfully from hatching of the Zoea I (Z I) to the third zoeal stage (Z III). Complete absence of starvation effects indicated obligatory lecithotrophy in Z I, while significantly delayed moulting and reduced biomass in unfed Z II proved that this stage is facultatively lecithotrophic. Although unfed Z III did not develop any further (obligatory planktotrophy), they still showed a high endotrophic potential, surviving for up to another 10 d (in total 2 wk from hatching), and utilizing about two-thirds of their initial biomass. Dramatically decreasing C:N ratios in unfed larvae suggest an almost complete metabolic degradation of internal lipid stores (visible as fat droplets in the hepatopancreas region), but little protein mobilization. Larvae obtained from 2 different females differed significantly in biomass at hatching and, correspondingly, also in maximum survival time, delay of moulting to the Z III and average rates of biomass utilization. In conclusion, the early larval stages of M. amazonicum depend very little on food, shifting from completely non-feeding behaviour (Z I) through facultative lecithotrophy (Z II), to planktotrophy (later stages). This ontogenetic pattern may be an adaptation to initial food limitation associated with larval export from limnic to estuarine environments.

“…Their highly variable morphology and the existence of morphotypes obstruct their taxonomic identification based only on these characteristics (Odinetz-Collart and Moreira, 1993;Odinetz-Collart and Magalhães, 1994;Porto, 1998;Bauzer et al, 2002;Anger et al, 2009). According to Zhang et al (2009) and Murphy and Austin (2002), there are many doubts and inconsistencies about the phylogenetic and taxonomic aspects of a great number of species from this genus, and answers to many of these questions remain contradictory, even when using COI and 16S rRNA markers, which are thought to be efficient for this goal.…”

ABSTRACT. The genus Macrobrachium includes prawns, which are widely distributed in lakes, floodplains, and rivers in tropical and subtropical regions of South America. This genus presents nearly 210 known species with great ecological and economic importance. However, few studies are related to the biology of these crustaceans. In this study, we analyzed the genetic variability and phylogenetic relationship between Macrobrachium amazonicum and Macrobrachium jelskii, which are closely related species. Additionally, they are syntopics and their taxonomy poses problems because it is difficult to differentiate between the species. We used the mitochondrial gene sequences COI and 16S rRNA to assess the genetic structure of these species in 3 populations that were collected from Tiete hydrographic basin (São Paulo State, Brazil). The interspecific Genetic variability in the genus Macrobrachium comparison of samples that were collected at the same and different locations showed a low rate of genetic variability. This similarity was attributed to the recent introduction of these species in the regions that were sampled and the habitat conditions in which they inhabit. In addition, these results may be consistent with the hypothesis that they are a single species, interspecific hybrids, or metapopulation. The dendrogram analyses did not reveal the formation of clusters, confirming the disturbances in the genetic structure of the samples that were analyzed in this study. These data are pioneers to these crustaceans, and they confirm the ecological and evolutionary problems between these Macrobrachium species.
