Macrobrachium amazonicum is an indigenous prawn vastly distributed in basins of South America, widely exploited by artisanal fisheries in northern and northeastern Brazil and, with great potential for aquaculture. This study aimed to investigate general aspects of population structure and reproductive characteristics (size at first maturity, fecundity and reproductive output) of M. amazonicum from two important areas to artisanal prawn fishing located at the mouth of the Amazon River, State of Amapá. The specimens were captured using 20 handcrafted traps called "matapi". A number of 5,179 prawns were captured, 2,975 females and 2,195 males resulting in 1.35:1 female to male ratio. Santana Island and Mazagão Velho showed females predominated in the population. A reproductive peak period was observed from January to April/2009 and in December/2010, coinciding with the period of higher rainfall. The recruitment peak occurred in June and July/2009. Egg-bearing females ranged in size (carapace length) from 11.10 to 29.6 mm. Fecundity increased with female size and reached up to 7,417 eggs. This amount of eggs is considered low if compared with other Macrobrachium estuarine species. Mean egg volume increased gradually from 0.121 to 0.24 mm³ during embryogenesis, representing 68.5% of overall increase from Stage I to Stage III. Eggs of M. amazonicum are small; this is typical for Macrobrachium species, which depends on brackish water to complete the larval development. Irrespective of female size, reproductive output of M. amazonicum varied between 4.8 and 21.85% of their body weight into eggs production. KEYWORDS: Palaemonid eggs, first maturation, fecundity, morphometric relationships, reproduction Aspectos reprodutivos do camarão Macrobrachium amazonicum (Decapoda: Palaemonidae) no estado do Amapá, foz do rio Amazonas RESUMO Macrobrachium amazonicum é uma espécie nativa vastamente distribuída nas bacias da America do Sul, sendo largamente explorada por pescadores artesanais no Norte e Nordeste do Brasil e com grande potencial para aquicultura. O objetivo deste trabalho foi abordar aspectos gerais da estrutura populacional e biologia reprodutiva (tamanho de primeira maturação, fecundidade e investimento reprodutivo) de M. amazonicum de duas importantes áreas de pesca artesanal de camarão localizada na foz do rio Amazonas, no Estado do Amapá. Os exemplares foram capturados usando 20 armadilhas artesanais, conhecidas localmente como matapi. Um total de 5.179 camarões foi capturado, dos quais 2.975 eram fêmeas e 2.195 eram machos, dando uma razão sexual geral de 1,35: 1 em favor das fêmeas. As proporções sexuais nas áreas de Ilha de Santana e Mazagão mostraram fêmeas predominando na população. Os picos reprodutivos nas duas áreas ocorreram de Janeiro a Abril/2009 e em Dezembro/2010, coincidindo com o período mais chuvoso. Os picos de recrutamento foram observados em junho e julho de 2009. O tamanho das fêmeas ovígeras variou de 11,10 mm a 29,6 mm de comprimento de carapaça. A fecundidade aumentou com o tamanho d...

Macrobrachium surinamicum is an indigenous prawn distributed from the lower Amazon and Tocantins river basins to Venezuela in the Orinoco Delta region. It is common bycatch fauna of Macrobrachium amazonicum artisan fishing in the states of Pará and Amapá. The aim of this study was to investigate aspects on reproductive biology (reproductive period, size of sexual maturity population, fecundity, reproductive output and recruitment) of M. surinamicum from four important areas to artisanal prawn fishing located at the Amazon River mouth (Amapá and Pará). The specimens were captured using 20 handcrafted traps called "matapi". A number of 675 prawns were captured, 258 males, 409 females and eight juveniles, resulting in 1:1.6 (Male: Female) sex ratio. The reproductive peak period occurred from March to July, coinciding with the higher rainfall period. The juvenile prawn occurred only in May and July. Total length of egg-bearing females ranged from 12.12 to 38.30 mm, with mean female length at first maturity (L50) RESUMOMacrobrachium surinamicum é uma espécie nativa de camarão de água doce distribuída do Brasil, nas bacias do rio Amazonas e Tocantins até a Venezuela na região do Delta do Orinoco. Este é fauna acompanhante comum da pesca artesanal de Macrobrachium amazonicum nos estados do Pará e Amapá. O objetivo deste trabalho foi abordar aspectos gerais da biologia reprodutiva (período reprodutivo, tamanho de primeira maturação, fecundidade, investimento reprodutivo e recrutamento) de M. surinamicum de quatro importantes áreas de pesca artesanal de camarão localizada na foz do rio Amazonas (Amapá e Pará). Os exemplares foram capturados usando 20 armadilhas artesanais, conhecidas localmente como matapi. Um total de 675 camarões foi capturado, 258 machos, 409 fêmeas e oito juvenis, resultando uma razão sexual geral de 1: 1,6 (macho:fêmea). Os picos reprodutivos ocorreram de março a julho, coincidindo com o período mais chuvoso. Os jovens foram observados em maio e julho. O comprimento total das fêmeas ovígeras variou de 12,12 a 38,30 mm, com o comprimento de primeira maturação (L50) estimado em 23,7 mm. A fecundidade aumentou com o tamanho das fêmeas, variando entre 174 e 1780 ovos por espécime. Volume médio dos ovos aumentou gradualmente durante a embriogênese saindo de 0,031 (Estágio I) para 0,060mm³ (Estágio III). Macrobrachium surinamicum dependem de água salobra para completar seu desenvolvimento larval. Independentemente do tamanho da fêmea, o investimento reprodutivo de M. surinamicum variou entre 4,3 % e 35,5% do seu peso corporal para a produção de ovos. O conhecimento da biologia reprodutiva relatada no presente estudo é uma ferramenta importante para ajudar a definir estratégias para preservar M. surinamicum na foz do Rio Amazonas. PALAVRAS-CHAVE: ovos de palaemonideos, fauna acompanhante, fecundidade, relações morfométricas, investimento reprodutivo.

“…The species is distributed in 11 states of the Brazilian territory, and in Colombia, Venezuela, the Guianas, and Peru (Coelho & Ramos‐Porto, ; Holthuis, ; Melo, ; Pileggi, Magalhães, Bond‐Buckup, & Mantelatto, ). Most studies of M. brasiliense addressed its population ecology (García‐Davílla, Alcantara, Vasquez, & Chujandama, ; Mantelatto & Barbosa, ; Oliveira, Sant'anna, & Hattori, ), and there are few published distribution records (García‐Davílla & Magalhães, ; Santos, Castro, & Magalhães, ). Despite the species' wide distribution, there have been few taxonomic reviews (Coelho & Ramos‐Porto, ; Pileggi & Mantelatto, ) and few studies of other aspects of the species' biology such as behavior (Nogueira, Costa, & Almeida, ), feeding behavior (Melo & Nakagaki, ), mass‐length relationships or other measures of physiological condition (Taddei et al, ), reproductive potential (Oliveira, Sant'anna, & Hattori, ), or larval morphology (Pantaleão, Gregatti, Taddei, & Costa, ).…”

Some decapod species have intraspecific morphological variations that result in distinct adult morphotypes that influence the population structure, social dominance, and reproduction of the population. Here we investigated whether this differentiation into morphotypes occurs in adult males of Macrobrachium brasiliense, through the analysis of relative growth and morphology. Specimens were collected in the region of Uberlândia, Minas Gerais state, southeastern Brazil. Seven dimensions of each male were measured: carapace length (CL), ischium length, merus length, carpus length, propodus length, dactylus length, and major cheliped length. Principal component analysis, clustering, and discriminant analyses were used to identify possible morphotypes. The analysis of relative growth was employed to estimate the growth patterns of body structures (dependent variables) in relation to the CL (independent variable). Two morphotypes were identified: Mirim, which has less developed chelipeds (23.31 ± 3.08 mm) with fewer spines, and Açu, which has larger chelipeds (41.39 ± 8.14 mm) with many well‐developed spines, especially in the merus. Most morphometric relationships differed significantly (p < .01) between the two morphotypes. The chelipeds were useful characters for the identification of the morphotypes of M. brasiliense, corroborating previous descriptions of the genus. We provide a detailed description of the main macroscopic characteristics that differed between morphotypes, which will enable their identification in future studies. Our results contribute to the knowledge of the population biology of M. brasiliense and should be considered in future investigations, since the presence of these male morphotypes probably influences the reproductive biology and population ecology of the species.
