Marine gastropods are consumed worldwide due to their nutritional quality, having important economic value in international markets. In the gulfs of Northern Patagonia (Argentina), marine gastropods are captured as complementary resources during bivalve artisanal fisheries. In this study, we determined the biochemical composition during the reproductive cycle of four edible marine gastropods abundant along the South-western Atlantic coast:Odontocymbiola magellanica,Buccinanops deformis,Buccinanops cochlidiumandTrophon geversianus. All the studied species presented high protein (36–70.8%), low lipids (0.02–1.50%) and intermediate glycogen content (3.22–14.08%). The main oviposition season was during spring and summer. The mean nutritional values indicate that the species studied provide a good source of nutrients appropriate to the human diet, reaffirming their value as a commercial resource. Taking into account the nutritional contribution and the reproductive season, the best period for the capture of these resources is during summer forO. magellanicaandT. geversianus, and during autumn forB. deformisandB. cochlidium. This work will help promote the consumption of Patagonian gastropods while ensuring their responsible capture, contributing to the sustainability of these valuable resources.

巴塔哥尼亚海洋腹足动物繁殖季节的营养成分

海洋腹足动物因其营养质量而在全球范围内消费，在国际市场上具有重要的经济价值。在北巴塔哥尼亚（阿根廷）的海湾，在双壳类手工渔业中捕获海洋腹足类动物作为补充资源。在这项研究中，我们确定了西南大西洋沿岸丰富的四种可食用海洋腹足动物在繁殖周期中的生化成分：麦哲伦齿孔菌,畸形蟾蜍,蠹虫和特罗丰. 所有研究的物种均呈现高蛋白（36-70.8%）、低脂（0.02-1.50%）和中等糖原含量（3.22-14.08%）。主要产卵季节是春季和夏季。平均营养价值表明，所研究的物种提供了适合人类饮食的良好营养来源，重申了它们作为商业资源的价值。考虑到营养贡献和繁殖季节，捕获这些资源的最佳时期是夏季O. magellanica和T. geversianus，而在秋季B. 畸形和B. cochlidium. 这项工作将有助于促进巴塔哥尼亚腹足动物的消费，同时确保负责任地捕获它们，从而促进这些宝贵资源的可持续性。
