The preservation of endemic species is crucial for maintaining balanced ecosystems, especially in unstable environments such as dammed areas. To analyze a possible competitive effect between cohabiting congeners, this study aimed to investigate the fecundity and reproductive investment of both species, using populations from the Lower Tietê in the Promissão Reservoir as a basis. Data were collected over the course of a year along the banks of the Tietê River, with up to 30 breeding females of each species sampled monthly. In addition to measuring cephalothorax length (CC), both females and their eggs were dry weighed. The developmental stage of each female’s eggs (initial – IN and final – FI) was also recorded. Fecundity and reproductive investment (IR) data were obtained from females with eggs in the IN stage. Simple linear regression was used to assess the relationship between fecundity and CC, while egg loss between IN and FI stages was analyzed using covariance analysis. Results showed significantly higher fecundity in M. amazonicum (717.16 ± 422.8 eggs) compared to M. jelskii (46.62 ± 16.44 eggs). However, M. jelskii exhibited a greater RI (14.24%) than its congener (12.68%). The higher fecundity of M. amazonicum may explain its competitive success, making it a promising candidate for aquaculture. In contrast, the higher IR of M. jelskii may confer an advantage in resource-limited environments, highlighting the importance of monitoring the reproductive dynamics of these species to ensure their viability in competitive, resource-scarce habitats.

Resumo
A preservação de espécies endêmicas é importante para a manutenção de ecossistemas equilibrados, especialmente em ambientes instáveis, como áreas de represamento. Com a finalidade de analisar um possível efeito competitivo entre congêneres que cohabitam, este estudo teve como objetivo investigar a fecundidade e o investimento reprodutivo de ambas as espécies, utilizando como base populações provenientes do Baixo Tietê, no reservatório de Promissão. A coleta de dados ocorreu ao longo de um ano, às margens do Rio Tietê, abrangendo mensalmente até 30 fêmeas embrionadas de cada espécie. Além do comprimento cefalotorácico (CC), fêmeas e respectivos ovos foram pesados a seco. O estágio de desenvolvimento dos ovos de cada fêmea (inicial – IN e final – FI) também foi registrado. Os dados de fecundidade e investimento reprodutivo (IR) foram obtidos utilizando fêmeas com ovos em IN. Uma análise de regressão linear simples foi realizada para relacionar a fecundidade com o CC. A perda de ovos entre IN e IF foi avaliada com análise de covariância. Os resultados indicaram uma fecundidade significativamente maior em M. amazonicum (717,16 ± 422,8 ovos) em comparação a M. jelskii (46,62 ± 16,44 ovos). No entanto, M. jelskii apresentou maior IR (14,24%) em relação ao seu congênere (12,68%). A maior fecundidade de M. amazonicum pode justificar seu sucesso competitivo, sendo uma espécie promissora para aquicultura. Em contrapartida, o elevado IR de M. jelskii pode fornecer uma vantagem em habitats limitados, destacando a importância de monitorar as dinâmicas reprodutivas dessas espécies para garantir sua viabilidade em ambientes competitivos com recursos escassos.
