As the turtle (Podocnemis expansa) and tracajá (Podocnemis unifilis) are the most important species in trade and local subsistence (SMITH, 1979). The present work aims to obtain information on the influence of P. expansa matrices, weight and size, on the characteristics of nests and pups, and the influence of temperature and incubation period on the sexual ratio of P. expansa nests . Data collection was carried out in two commercial turtle breeders located in the municipality of Iranduba and Manacapuru / AM, where the spawning period was monitored. Data were collected on nest dates, nest depths and width, nest distance (trawl size and paw width), characteristic of hatching (rate and hatching, biometry and sexing of the pups) and the collected data of climatic data by means of Data Logger placed within the selected nests. Pearson correlation analyzes were performed to verify if the characteristics of the matrices influence the nests (number of eggs, egg weight and size, egg mass, width and depth of nests) and pups (initial pups size and weight, pups, hatching rate, incubation period). Among the variables that had the highest correlation index (Pearson correlation> 0.50 and p value 0,50 e valor p < 0,05), foram aplicadas regressões lineares para avaliar o índice de significância das correlações encontradas. O tamanho das fêmeas influencia no desempenho da produção de filhotes, por isso é importante selecionar matrizes de grande porte, uma vez que assim como observado na natureza. Ovos de tamanhos maiores produzem filhotes maiores e mais pesados, e o número de ovos influenciou diretamente na massa total do ninho. A temperatura média de incubação influência com uma relação positiva o tamanho e peso dos filhotes
