Several compounds (carbohydrates, proteins, hormones, etc.) were used in fish to quantify the level of stress. Our investigations focused on two parameters of the blood plasma: plasma glucose and serum/plasma fructosamine (SeFa) that has not been tested on fish as yet. Experiments were conducted on two fish species. The concentrations of these components were investigated on Common carp (Cyprinus carpio L., 1758) and on Prussian carp (Carassius auratus gibelio BLOCH, 1783) from the Gödöllö-Isaszeg pond system by creating conditions different from ideal. Stress effects caused a fluctuating tendency in blood plasma glucose levels each week for both Common carp and Prussian carp, thus, there was no steady growth. However, SeFa concentrations exactly followed stress effects, moreover, it tolerated short-term negative effects (handling of fish, blood sampling) and did not cause alterations at individuals blood samplings. This experimental method can offer assistance to farmers in the daily routine (e.g. in fish transport) and in the technology of propagation.
几种化合物（碳水化合物、蛋白质、激素等）被用于鱼类以量化应激水平。我们的研究集中于血浆的两个参数：血浆葡萄糖和血清/血浆果糖胺（SeFa），后者尚未在鱼类上进行过测试。实验在两种鱼类上进行。在来自戈多洛-伊萨泽格池塘系统的鲤鱼（Cyprinus carpio L., 1758）和鲫鱼（Carassius auratus gibelio BLOCH, 1783）上，通过创造非理想条件来研究这些成分的浓度。应激效应导致鲤鱼和鲫鱼每周血浆葡萄糖水平都呈现波动趋势，因此，没有稳定增长。然而，SeFa浓度确切地跟随应激效应，此外，它能耐受短期负面影响（鱼类处理、采血），并且在个体采血时不会引起变化。这种实验方法可以在日常工作（如鱼类运输）和繁殖技术方面为养殖者提供帮助。
