我们测试的假设，活动率可以代表一个大的和可变的组成部分，鱼的能量预算。我们执行了五个实验之间的7月15日和1991年8月2日，估计增长，消费和活动率的五个半年度的溪红点鲑fontinalis保持在现场外壳。在我们的研究中，平均鱼湿重从3.47克下降到2.89克。这意味着总共损失了3，544卡（所有鱼的总和）。消耗率平均为0.18 g（干）。100 g湿重-1。d-1。 围隔内鱼的食物总消耗量为112.9至188.8卡。D 1.平均游泳速度为3.9 - 7.9 cm。s-1条件下与自发游泳相关的能量消耗（所有鱼类合并）范围从94.0到498.1卡。d-1。自发活动代谢率（标准代谢+净活动率）是标准代谢相关成本的1.6-3.8倍。我们的研究支持了这一假设，即活动率可以是一个大的和可变的组成部分，鱼的能量预算。
We tested the hypothesis that activity rates can represent a large and variable component of a fish's energy budget. We executed five experiments between July 15 and August 2, 1991, to estimate growth, consumption, and activity rates of five young-of-the-year brook trout Salvelinus fontinalis kept in field enclosures. Mean fish wet weight decreased from 3.47 to 2.89 g during our study. This represented a total loss of 3,544 cal (all fish combined). Consumption rates averaged 0.18 g dry . 100 g wet-1 . d-1. The total quantity of food consumed by the fish inside the enclosure ranged from 112.9 to 188.8 cal . d 1. Median swimming speed ranged from 3.9 to 7.9 cm . s-1. Energetic costs associated with spontaneous swimming (all fish combined) ranged from 94.0 to 498.1 cal . d-1. Spontaneous activity metabolic rate (standard metabolism + net activity rate) represented 1.6-3.8 times the costs associated with standard metabolism. Our study supported the hypothesis that activity rates can be a large and variable component of a fish's energy budget.
