Life history traits, metabolic status and reproductive success data for brown trout in an experimental channel

Dataset on brown trout (Salmo trutta) life history, metabolic status and reproductive success used in a control experiment of reproduction, to study the impact of water flow stochasticity on reproductive investment and reproductive success. Experiment A and B1 are under constant water flow. Experiment B2 is under stochastic water flow. In A, only wild fish from river Bastan, France, are placed in the channel. FOr experiments B1 and B2, wild fish from river Bastan, France , and river Urumea, Spain, are placed in sympatry in the channel. At the beginning and end of the experiment and therefore the reproduction period (duration: 2 months), fish are measured for a set of traits, and 2 months after they are removed from the channel and released in their river of origin, emerging fry are sampled and genetically assigned to their potential parents.

本数据集涵盖褐鳟（Salmo trutta）的生活史、代谢状态与繁殖成功率相关数据，源自一项繁殖对照实验，旨在探究水流随机性对繁殖投入与繁殖成功率的影响。实验A与B1均采用恒定水流条件，实验B2则采用随机水流条件。实验A仅将采自法国巴斯唐河（Bastan River）的野生褐鳟放置于养殖槽中。实验B1与B2中，则将采自法国巴斯唐河与西班牙乌鲁梅阿河（Urumea River）的野生褐鳟以同域共存的方式置于养殖槽内。在实验开始时、实验结束（即整个繁殖周期，时长为2个月）时，会对褐鳟的一系列性状进行测量；实验结束2个月后，将养殖槽内的褐鳟移出并放归其原栖息河流，同时对孵出的仔鱼进行采样，并通过遗传学手段将其归属至潜在亲本个体。
