Abstract

: The present study aims to determine, for the first time, the annual breeding cycle and the biochemical changes in the gonads of the North African freshwater crab, Potamon algeriense (Bott, 1967). Monthly collections were carried out by hand, from October 2018 to September 2019 in Oued Zegzel, a mountain stream in the Northeast of Morocco. The gonad size reached high values in the dry season (June to September) showing the maximum breeding activity during these months. By June, the gonads of most of the individuals attained full maturity where the spawning began. Spawning terminated by the end of September then the gonads entered a quiescent period. Histological observations of the gonads revealed that the ripening of the gonads started during March and extended up to May. During the maturation of the gonads, protein, fat

北非淡水蟹阿尔及利亚肥蟹(Potamon algeriense, Bott, 1967)生殖腺的繁殖周期和季节生化变化(短目:肥蟹科)

本研究旨在首次确定北非淡水蟹(Potamon algeriense)的年度繁殖周期和性腺的生化变化(Bott, 1967)。从2018年10月到2019年9月，在摩洛哥东北部的一条山间溪流Oued Zegzel进行了月度手工收集。性腺大小在旱季(6 ~ 9月)达到最大值，表明繁殖活动在这几个月最为活跃。到6月，大多数个体的性腺在产卵开始时达到完全成熟。九月底产卵结束，性腺进入休眠期。性腺的组织学观察表明，性腺的成熟始于3月，一直延续到5月。在性腺成熟期间，蛋白质，脂肪
