The study aimed to analyze the Colossoma macropomum reproductive behavior and quality of the female gametes throughout the reproductive season. The experiment was carried out in Pimenta Bueno - Rondônia State (Northern Brazil) during the reproductive season (2010-2011) using 36 females. Each sampling was performed on a 15 ± 5 days interval. Female gametes were collected by stripping and the following analyses were performed: weight of oocytes released (g); productivity index, fertilization and hatching rate. During the sampling period was verified effect (p < 0.05) of collecting time into the season for oocytes weight, productivity index and fertilization rate. Although the period 3 (December) did not differ significantly from other periods, it showed better parameters for the quality of C. macropomum oocytes.
该研究旨在分析巨脂鲤在整个繁殖季节的繁殖行为及雌配子质量。实验于繁殖季节（2010 - 2011年）在巴西北部朗多尼亚州的皮门塔布埃诺进行，使用了36尾雌鱼。每次采样间隔为15±5天。通过采卵收集雌配子，并进行以下分析：排出的卵母细胞重量（克）；生产力指数、受精率和孵化率。在采样期间，验证了采卵时间对卵母细胞重量、生产力指数和受精率的季节影响（p < 0.05）。尽管第3阶段（12月）与其他阶段无显著差异，但巨脂鲤卵母细胞质量的各项参数在此阶段表现更佳。
