“…Studies on Ps. chryseus and E. amazoniensis are scarce and we only found information on the larval development of both species (Magalhães 1986a(Magalhães , 1988Odinetz-Collart and Magalhães 1994).…”

The bioecology of freshwater prawns can be understood by studying their reproductive biology. Thus, the aim of this paper was to determine and compare the reproductive potential of four freshwater caridean prawns collected in the Amazon region. For two years, we captured females of Macrobrachium brasiliense, Palaemon carteri, Pseudopalaemon chryseus and Euryrhynchus amazoniensis from inland streams in the municipality of Itacoatiara (AM). At the laboratory, we measured the biometric variables total length, carapace length, abdomen length and total weight, and recorded the number of eggs (NE) by direct counting. There was a significant difference for all variables between the species. The females of M. brasiliense were the most abundant and had the largest sizes and NE. However, the fecundity index shows that P. carteri has the highest reproductive potential of the four species. Despite the differences in size and weight, all the species showed low fecundity, which is a characteristic of continental palemonidean K strategist prawns.

“…As larvas atingem o estágio de juvenis entre 5 e 7 dias após a eclosão, período em que as larvas utilizam apenas os recursos oriundos do vitelo. A fecundidade é de 14 a 43 ovos (Magalhães, 1986), podendo ser considerada baixa quando comparada à apresentada por outras espécies dulcícolas da família Palaemonidae.…”

“…A estruturação genética, variabilidade morfológica e presença de barreiras geográficas ao longo de sua distribuição levantam a possibilidade de espécies crípticas filogeneticamente próximas a P. ivonicus. A espécie tem desenvolvimento larval abreviado, com ovos grandes (2,31 ± 0,14 x 1,49 ± 0,09 mm) e em pequena quantidade (12 a 43 ovos/fêmea); o desenvolvimento larval consta de três estágios larvais, que duram de 4 a 6 dias, e a larva recém-eclodida tem comprimento total de 4,55 ± 0,14 mm (Magalhães, 1986). Essa estratégia reprodutiva, aliada à ao tipo de ambiente onde ocorre, limita a capacidade de dispersão entre bacias e propicia a existência de estruturação genética (Carvalho et al, dados não publicados).…”
