Longer exposure to warm water increases subsequent thermal tolerance of brook trout in cold water: acclimation timing and physiology

This record contains data generated from a laboratory-based study examining the persistence of warm water acclimation following cold water recovery in an iconic cold-water species, the Eastern brook trout. The data set includes Critical Thermal Tolerance (CTmax) measures of fish in treatment groups: control (15 degrees C throughout), 1, 3, 7, and 14 days in warm water exposure (22 degrees C) followed by a 2 week cold water (15 degrees C) recovery. Physiological indices were also measured at both warm water treatment and post recovery. Growth and CTmax was recorded after two weeks of recovery temperature for control and all warm treatment groups, and after 30 and 42 days of cold water recovery for control and 14 day warm water treatment group.

本数据集源自一项实验室基础研究，旨在探究标志性冷水物种东部溪红点鲑（Eastern brook trout）在经历冷水恢复后，其温水驯化效应的持续性。数据集包含各处理组鱼类的临界热耐受（Critical Thermal Tolerance，CTmax）测定数据：对照组（全程维持15℃水温）、以及经22℃温水分别暴露1、3、7、14天后，再进行为期2周15℃冷水恢复的处理组。研究同时在温水处理阶段及冷水恢复后测定了多项生理指标。对照组与所有温水处理组均在恢复水温下饲养2周后记录其生长情况与临界热耐受值；对照组及14天温水处理组则额外在冷水恢复30天和42天时记录上述两项指标。
