<b>Thermal carryover effects of embryo incubation temperature through ontogeny in brook trout</b>

We quantified possible thermal carryover effects in brook trout (<i>Salvelinus fontinalis</i>) across ontogeny and multiple genetically distinct wild and hatchery-origin populations. Populations were incubated in the laboratory in four differing thermal regimes: ambient stream-fed water, chronically warmed, ambient with a mid-winter cold-shock, and short-term warming. We examined upper thermal tolerance at the embryonic, fry (10 weeks post-full-hatch and 27-30 weeks post-full-hatch) and gravid adult life stages. In a separate experiment, we exposed developing embryos to seven-day heat stress events immediately following fertilization and at the eyed-egg-stage to examine possible thermal carryover effects at the 37-weeks-post-full-hatch stage.

本研究量化了溪红点鲑（*Salvelinus fontinalis*）在个体发育过程中，以及多个遗传分化显著的野生种群与人工繁育种群的热遗留效应（thermal carryover effects）。研究团队在实验室中对各种群采用四种不同热调控培养方案：天然溪流原水温供水组、长期慢性加温组、冬季中期冷冲击组以及短期加温组。我们分别检测了胚胎期、仔鱼期（出膜后10周、出膜后27~30周）以及怀卵成体的高温耐受上限。在另一项独立实验中，我们分别于受精后即刻以及眼斑胚胎期对发育中的胚胎施加7天热胁迫处理，以探究出膜后37周阶段的潜在热遗留效应。

背景概述

该数据集研究了溪鳟胚胎孵化温度的热遗留效应，通过实验室控制四种不同热处理条件（如持续升温、冷休克等），测量了胚胎、鱼苗和成体多个生命阶段的上热耐受性。数据集包含原始实验数据，重点关注热应激事件对鱼类发育的跨阶段影响，适用于鱼类生理学和气候变化适应研究。
