Abstract

We describe sclerochronological analyses of tadpole codling (Salilota australis) vertebrae as a proxy for the seasonal timing of fishing activities at one Middle Holocene (6500 BP) and three Late–Middle Holocene (3500–2500 years BP) archaeological sites located in Seno Otway and in the central zone of the Strait of Magellan, Chile. These data provide an approximation of the population characteristics of the species in the past by estimating the relationship between size and age of the archaeological fish and comparing their growth rate to those of modern specimens captured monthly over one year. The results showed that the size at age was significantly larger in archaeological samples than in the modern reference collection. Our results indicate that fishing activities took place throughout the year at the Late Holocene sites, with a special emphasis on the cold season, while the Middle Holocene site showed a tendency to catch tadpole codling during the warm season.

摘要

我们描述了蝌蚪蝌蚪（Salilota australis) 椎骨作为位于 Seno Otway 和麦哲伦海峡中部地区的一个中全新世 (6500 年前) 和三个晚至中全新世 (3500-2500 年前) 考古遗址的季节性捕捞活动时间的代表，智利。这些数据通过估计考古鱼的大小和年龄之间的关系并将它们的生长速度与一年内每月捕获的现代标本的生长速度进行比较，提供了过去物种种群特征的近似值。结果表明，考古样本的年龄大小明显大于现代参考收藏。我们的研究结果表明，在全新世晚期地点全年都有捕鱼活动，特别强调寒冷季节，
