Abstract:

Macrobrachium carcinus is a Brazilian native prawn with recognized potential for use in aquaculture activities. However, there is little information about the natural diet and feeding habits of this species. The aim of this study was the identification of the diet items of M. carcinus based on the analysis of the stomach contents. Specimens were collected in the Amazon River estuary between January 2009 and January 2010. The stomach analysis was carried out by using the frequency of occurrence (FO), methods of points (MP) and feeding index (FI). It was observed that prawns fed on detritus, animals and plant fragments as the most important food items. Sediment accounted for the main stomach content, accounting for 43.2% by the MP, 44.9% by FI and 100% by the FO. Sexual differences in feeding preferences were not found in this study, and seasonal differences in the frequency of items ingested by M. carcinus were not observed. The results indicated that M. carcinus can be considered omnivorous species, but with an important carnivorous component, similar to that found in other Macrobrachium species.

Abstract:

ABSTRACT Macrobrachium carcinus is a Brazilian native prawn with recognized potential for use in aquaculture activities. The aim of this study was to describe and illustrate in detail the morphology of the M. carcinus foregut. The foregut comprises the mouth, esophagus and stomach. It is lined by a simple cylindrical epithelium overlain by chitinous cuticle. The cardiac chamber is well supplied with muscles and lined with chitin thickened in places to form a complex, articulating set of ossicles. The ossicles and setae inside the cardiac chamber seem to direct the food movement through the cardiac chamber and sort the food according to particle size as digestion takes place. Twenty-one basic ossicles were observed in the stomach ofM. carcinus and are divided into seven categories, reflecting their presumed functional roles. The significance of these morphological features is discussed in terms of its implication in feeding management that can support future commercial farms of this important fishery resource.

Abstract:

Macrobrachium carcinus (Linnaeus, 1758) is a species of freshwater shrimp widely distributed from Florida southwards to southern Brazil, including southeast of Mexico. In the present work, we identified a putative trypsin-like protease cDNA fragment of 736 nucleotides from M. carcinus hepatopancreas tissue by the 3′RACE technique and compared the deduced amino acid sequence to other trypsin-related proteases to describe its structure and function relationship. The bioinformatics analyses showed that the deduced amino acid sequence likely corresponds to a trypsin-like protease closely related to brachyurins, which comprise a subset of serine proteases with collagenolytic activity found in crabs and other crustacea. The M. carcinus trypsin-like protease sequence showed a global sequence identity of 94% with an unpublished trypsin from Macrobrachium rosenbergii (GenBank accession no. AMQ98968), and only 57% with Penaeus vannamei trypsin (GenBank accession no. CAA60129). A detailed analysis of the amino acid sequence revealed specific differences with crustacean trypsins, such as the sequence motif at the beginning of the mature protein, activation mechanism of the corresponding zymogen, amino acid residues of the catalytic triad and residues responsible for substrate specificity.

Abstract:

Durante a operação do elevador para peixes da Usina Hidrelétrica Santa Clara, de novembro de 2003 a março de 2004, todos os crustáceos palaemonídeos adultos que utilizaram o mecanismo foram contados e o número de jovens estimado. Duas espécies foram registradas: Macrobrachium carcinus (Linnaeus, 1758) e Macrobrachium acanthurus (Wiegmann, 1836). A utilização do mecanismo por adultos foi bastante restrita, com apenas 185 exemplares registrados. Porém, o número de jovens de M. carcinus utilizando o elevador foi estimado em 19.120 indivíduos. Embora o mecanismo avaliado tenha permitido a passagem dos palaemonídeos para montante do barramento, ficou clara a necessidade de novos arranjos estruturais e de manejo específicos para esses animais. Essas ações se referem ao desenvolvimento de estruturas direcionadas para a sua passagem e a adoção de vertimentos programados durante o período reprodutivo para permitir o carreamento de larvas para jusante. Esses dois caminhos representam formas efetivas de manejo, imprescindíveis para a manutenção das populações deste importante componente da biota aquática.

Abstract:

This study constitutes the most comprehensive effort ever done to assess the faunal diversity of the Macrobrachium genus within two ecoregions that encompass part of the northeastern Brazil: the Northeastern Caatinga & Coastal Drainages, and the São Francisco (Lower-middle and Lower portions). Through sampling in several of their hydrographic basins, bibliographic research, and consulting scientific collections, our results reveal the occurrence of five species along these ecoregions: Macrobrachium acanthurus, M. amazonicum, M. carcinus, M. jelskii and M. olfersii. We also provide the first record of these species for several river basins in both ecoregions. Additionally, we confirm the occurrence of M. carcinus from Rio Grande do Norte State and provide updated distribution maps for each species in the studied area. This carcinofauna survey may form the basis for future evaluations of eventual anthropic impacts on biological diversity resulting from projects being implemented in these regions, which involve the São Francisco interbasin water transfer.

Abstract:

El género Macrobrachium comprende más de cien especies, de las cuales 26 pertenecen al continente americano (Pascual, 2005); comúnmente son conocidos como camarones de río y/o langostino. Debido a su trascendencia como recurso pesquero se les considera de gran importancia económica, principalmente Macrobrachium carcinus y M. acanthurus, los cuales son bien conocidos y explotados en la mayoría de las comunidades ribereñas de toda Latinoamérica (García-Guerrero, Becerril-Morales, Vega-Villasante, & Espinosa-Chaurand, 2013).Durante el periodo de estudio (2006-2007) se capturó un total de 1180 ejemplares. De éstos, 447 individuos fueron Macrobrachium acanthurus; 622, M. carcinus, y 111 fueron M. olfersii. Todas las capturas se realizaron con nasas de bambú de la especie Guadua del tipo Amplexifolia que es nativo de Nicaragua.Durante el estudio, la temperatura promedio fue 27,2 ± 1,25 °C (rango: 25 - 29 °C), transparencia promedio de 0,3 ± 0,17 m (rango: 0,26 - 0,45 m) y la profundidad promedio de 3 ± 0,25 m (rango: 2 - 4,5 m). En la proporción sexual (hembra/macho) hubo dominancia de machos. Para M. carcinus la proporción fue (1H: 0,9M) con un valor de χ2 = 2,57, sin diferencia significativa; M. acanthurus presentó una proporción (1H: 1,66M) con un valor de χ2 = 18,53, con diferencia significativa, y M. olfersii mostró una proporción (1H: 0,8M) con valor de χ2 = 0,73, sin diferencia significativa. Existe diferencia significativa cuando (χ2 < 3,84 y p > 0,05) (Vazzoler, 1996).M. carcinus presentó un promedio de Longitud Total (LT) de 15,8 ± 4,5 cm (rango: 3,6 - 24 cm) y un Peso Total (W) de 105,4 ± 82,5 g (rango: 1,7 - 382 g). Para las tres especies el modelo que mejor se ajusta al crecimiento de la población es el modelo polinómico, en M. carcinus (W = 1,6 LT2 - 28,2 LT + 118,6) explica más del 90% de la relación entre el W y LT (R2 = 0,9046). M. acanthurus presentó LT promedio de 11,7 ± 4,9 cm (rango: 4,3 - 26 cm) y W de 47,1 ± 66,2 g (rango: 1,3 - 383 g), el modelo de crecimiento de esta población (W = 1,2 LT2 - 19,5 LT + 79,36) explica más del 93% de la relación entre W y LT (R2 = 0.9395).Finalmente, M. olfersii presentó LT promedio de 6,4 ± 1,3 cm (rango: 3,5 - 9,6 cm) y un W de 4,2 ± 1,8 g (rango: 1,2 - 9,7 g), el modelo de crecimiento de esta población (W = 0,22 LT2 - 1,8 LT + 6,5) explica más del 60% de la relación entre W y LT (R2 = 0,621) en hembras y menos del 30% en machos (R2 = 0,294).

Abstract:

Crustaceans are major constituents of aquatic ecosystems and, as such, changes in their behavior and the structure and function of their bodies can serve as indicators of alterations in their immediate environment, such as those associated with climate change and anthropogenic contamination. We have used bioinformatics and a de novo transcriptome assembly approach to identify potential targets for developing specific antibodies to serve as nervous system function markers for freshwater prawns of the Macrobrachium spp. Total RNA was extracted from brain ganglia of Macrobrachium carcinus freshwater prawns and Illumina Next Generation Sequencing was performed using an Eel Pond mRNA Seq Protocol to construct a de novo transcriptome. Sequencing yielded 97,202,662 sequences: 47,630,546 paired and 1,941,570 singletons. Assembly with Trinity resulted in 197,898 assembled contigs from which 30,576 were annotated: 9,600 by orthology, 17,197 by homology, and 3,779 by transcript families. We looked for glutamate receptors contigs, due to their main role in crustacean excitatory neurotransmission, and found 138 contigs related to ionotropic receptors, 32 related to metabotropic receptors, and 18 to unidentified receptors. After performing multiple sequence alignments within different biological organisms and antigenicity analysis, we were able to develop antibodies for prawn AMPA ionotropic glutamate receptor 1, metabotropic glutamate receptor 1 and 4, and ionotropic NMDA glutamate receptor subunit 2B, with the expectation that the availability of these antibodies will help broaden knowledge regarding the underlying structural and functional mechanisms involved in prawn behavioral responses to environmental impacts. The Macrobrachium carcinus brain transcriptome can be an important tool for examining changes in many other nervous system molecules as a function of developmental stages, or in response to particular conditions or treatments.

Abstract:

Freshwater prawns of the genus Macrobrachium are one of the important components of circumtropical marine, estuarine, and freshwater environments. They have been extensively exploited for human consumption for many years. More than 250 species reflect the evolutionary success of this highly diversified group, with a complex and challenging taxonomy due to morphological variations and vast geographical distribution. Although genetic approaches have been used to clarify phylogenetic and taxonomic aspects of Macrobrachium species, cytogenetic information is still very scarce and mostly focused on chromosome number and morphology. Here, we present chromosome data for three species from the Neotropical region, M. carcinus, M. acanthurus, and M. amazonicum, and one species from the Oriental region, M. rosenbergii. Using conventional cytogenetic approaches and chromosome mapping of repetitive DNAs by fluorescence in situ hybridization (FISH), we identified numerical diversification of the diploid set, within and between both zoogeographic regions. These included M. acanthurus and M. amazonicum sharing diploid chromosomes of 98, while M. carcinus has 94, and M. rosenbergii has 118 chromosomes. Argentophilic sites are also variable in number, but they occur in a much higher number than 18S rDNA, representing two to 10 sites within the study species. Microsatellites repeat motifs are also abundant in the chromosomes, with a co-localization and uniform distribution along the chromosome arms, but completely absent in the AT-rich centromeric regions. As a whole, our study suggests that the 2n divergence was followed by a considerable rDNA diversification. The abundance of the exceptional amount of microsatellite sequences in the chromosomes also suggests that they are essential components of the Macrobrachium genome and, therefore, maintained as a shared feature by the species, the reason for which is yet unknown.

Abstract:

Macrobrachium is distributed globally in most biogeographical regions, and contains species with interesting mechanisms of evolution. We conducted an exhaustive survey on São Sebastião Island, the largest coastal island of the state of São Paulo. Here we provide a list of species (M. acanthurus, M. carcinus, M. heterochirus, M. olfersi, M. potiuna) together with the diagnosis, distribution, and remarks on each species, and a key for their identification. We compare our findings with available information on the genus. The high diversity of freshwater shrimps on the island is interesting in terms of biogeographical and evolutionary processes.

Abstract:

Os camarões de água doce do gênero Macrobrachium (Spence Bate, 1868) encontram-se amplamente distribuídos nas Américas e, numericamente este é o gênero dominante da família Palaemonidae. O Estado do Maranhão não dispõe de trabalhos voltados para crustáceos de água doce, sendo este o primeiro estudo realizado com o objetivo de apresentar informações taxonômicas das espécies registradas, com mapa de ocorrência geográfica, características biológicas e ecológicas, uma chave de identificação do gênero Macrobrachium para o Estado, bem como aspectos de conservação. Para isso, oito riachos do Leste do Maranhão, foram amostrados com puçás, peneiras e rede de arrasto, passados no fundo e na vegetação marginal submersa por um período de 20 minutos em um trecho de 150m. Em laboratório, os espécimes foram identificados, mensurados e sexados. Um total de 526 espécimes foram coletados, distribuídos em cinco espécies, sendo: M. carcinus (N=01), M. olfersii (N=55), M. acanthurus (N=116), M. amazonicum (N=119) e M. jelskii (N=235). Somente em M. acanthurus e M. jelskii foram registradas fêmeas ovígeras, M. jelskii apresentou fecundidades de 1 a 65 ovos, ao passo que para a única fêmea ovígera de M. acanthurus foram contados 662 ovos. Também foi elaborado uma chave de identificação do gênero Macrobrachium para o Maranhão. Assim, confirmou-se os registros destas espécies para o Estado e ampliação da área de distribuição, com mapas de ocorrência.

Evaluate the effects of varying dietary protein and lipid levels on the growth and body composition of adult freshwater prawns, Macrobrachium carcinus (Linnaeus 1758), in a recirculation system for 11 weeks (77 days). Materials and methods. The experimental treatments were assigned in triplicate. Six test diets were formulated with three different protein levels (35, 40 and 45%) and two lipid levels (8 and 13%). Results. The highest survival rate, growth indices and feed utilization were observed for M. carcinus adults fed protein:lipid diets of 35:13, 40:13 and 45:13, and the lowest values for these parameters were recorded for prawns fed diets with the lowest lipid levels; the differences in these parameters between these types of diets were significant (p<0.05). A nonsignificant tendency for an increased percentage of protein in the body with an increased dietary protein level was observed. The percentage of lipids decreased with an increasing dietary protein level, and no definite trends in ash content were found. Conclusions. The results suggest that a diet with 35% dietary crude protein and 13% lipids enhances the growth and body composition of adult M. carcinus.

Abstract:

A produção mundial de camarões de água-doce atingiu em 2018 o montante de 512.191 toneladas, representando um crescimento de 14,26% em um período de dez anos. A produção brasileira, neste mesmo período, aumentou 50%, alcançando em 2018 a marca de 150 toneladas produzidas. A criação brasileira de camarões de água-doce é reconhecida como potencial alternativa na produção de crustáceos, pois possui importantes vantagens em relação à carcinicultura marinha, tais como independência da água salgada na fase de engorda, a possibilidade de implantação em pequenas propriedades e, consequentemente, seu potencial baixo impacto ambiental. Das 17 espécies brasileiras de camarões de água-doce, apenas três apresentam interesse econômico e alto potencial de cultivo: Macrobrachium acanthurus, Macrobrachium carcinus e Macrobrachium amazonicum. Dada a importância desta atividade no brasil e o potencial de melhora de sua produtividade que novos estudos sobre a biologia deste grupo podem trazer, os objetivos deste estudo foram comparar as relações biométricas entre machos e fêmeas de M. acanthurus e verificar se há ocorrência de dimorfismo sexual que justifique um possível cultivo monossexo. Vinte e oito exemplares machos e setenta e sete exemplares fêmeas de M. acanthurus foram coletados em Garuva (SC) e levados ao Laboratório de Aquicultura do IFC Campus Araquari. De cada exemplar, foram medidos o comprimento do cefalotórax (CCE), o comprimento de abdômen (CAB) e o comprimento do telson (CTE) que, somados, originam o comprimento total (CTT). Foram calculados, para cada sexo, os índices CCE/CAB, CTE/CAB e CAB/CTT. Não foi observado crescimento alométrico em M. acanthurus, independente do sexo. Todavia as fêmeas de M. acanthurus mostraram ter, proporcionalmente, maior tamanho de abdômen quando comparadas aos machos. Porém, para se concluir se é viável economicamente realizar produção monossexo de M. acanthurus, são necessários estudos que avaliem a taxa de conversão alimentar de cada sexo, além das suas taxas de crescimento.

Abstract:

A produção mundial de camarões de água-doce teve, entre os anos de 2009 e 2018, um crescimento de 14,26%, alcançando no final de 2018 a marca de 512.191 toneladas. O Brasil, neste mesmo intervalo teve um salto de produção de 100 toneladas (em 2009) para 150 toneladas em 2018, que significou um incremento de 50% em sua produção. A criaçãobrasileira de camarões de água-doce apresenta algumas vantagens quando comparada à carcinicultura marinha, como o não-uso de água salgada na fase de engorda, a possibilidade de implantação em pequenas propriedades e, desta forma, seu potencial baixo impacto ambiental. Das espécies brasileiras conhecidas de camarões de água-doce, três apresentaminteresse econômico: Macrobrachium acanthurus, Macrobrachium carcinus e Macrobrachium amazonicum. Diante da importância da carcinicultura de água-doce no brasil e do potencial que novos estudos sobre a biologia deste grupo tem de melhorar de a produtividade desta atividade, os objetivos deste estudo foram determinar se há aumento da produção de ovos de fêmeas de M. acanthurus com a adição de rejeito de pesca a sua alimentação, estabelecer razões entre a produção de ovos e o tamanho das fêmeas e comparar estas razões entre fêmeas submetidas a diferentes manejos alimentares. Setenta e sete exemplares fêmeas de M. acanthurus foram coletadas em Garuva (SC) e levadas ao Laboratório de Aquicultura do IFC Campus Araquari. De cada exemplar, foram aferidos o comprimento total (CTT; em cm) e o peso (P; em g). Após um período de 30 dias de aclimatação, os exemplares foram colocados em gaiolas a uma densidade de estocagem de 10 exemplares.m-3 e submetidos a dois diferentes tratamentos em triplicata: tratamento controle (CTRL) onde os exemplares foram alimentados com ração comercial para engorda de camarão marinho (40% proteína bruta) a uma taxa de arraçoamento de 5% da biomassa total, e o tratamento T1, onde os exemplares foram alimentados com ração comercial para engorda de camarão marinho (40% proteína bruta) a uma taxa de arraçoamento de 5% da biomassa total, acrescido de vísceras de peixe, a uma taxa de 5% da biomassa total em peso úmido de vísceras. As biometrias foram programadas para serem realizadas quinzenalmente até se completar 60 dias de experimento, onde seriam medidos em cada tratamento o CTT e o P, além da realização da retirada de ovos de fêmeas ovígeras, caso ocorressem, para posterior pesagem e contagem dos ovos. Com estas informações, seriam também calculadas o total deovos por grama, em cada fêmea, além de se calcular também a produtividade de ovos por cm de fêmea e por grama de fêmea. Infelizmente, a ocorrência da pandemia permitiu que fosse realizada apenas uma biometria, sem que fosse realizada a contagem dos ovos. Como resultados obtidos, verificou-se que não houve diferenças entre os tratamentos quanto às variáveis sobrevivência, taxa de fêmeas ovígeras, peso médio das fêmeas ou peso médio dos ovos. Todavia, é necessário se fazer a contagem de ovos para se verificar se há diferenças relacionadas à quantidade e ao tamanho dos ovos.
