It has been demonstrated by the example of the crucian carp (Carassius carassius) that a 1-hour stay of fish in a combined magnetic field with resonance parameters for calcium ions decreases the proteolytic and amylolytic activities of their intestinal enzymes. It has been found that a 1-hour exposure to a combined magnetic field with resonance parameters for potassium ions has almost no effect on the activity of proteinases, but it decreases the amylolytic activity. It has been noted that the activity of proteases and glycosidases is lower under hypomagnetic conditions. Upon the inversion of the vertical component of the geomagnetic field, the proteolytic activity of the intestinal mucosa in C. carassius decreases, while the amylolytic activity becomes higher compared to the control. Possible effects of magnetic fields on the activity of digestive hydrolases in fish are discussed.
以鲫鱼（Carassius carassius）为例已证明，鱼在具有钙离子共振参数的复合磁场中停留1小时会降低其肠道酶的蛋白水解和淀粉水解活性。已发现，暴露于具有钾离子共振参数的复合磁场1小时对蛋白酶活性几乎没有影响，但会降低淀粉水解活性。已注意到，在低磁场条件下蛋白酶和糖苷酶的活性较低。在地磁场垂直分量反转时，鲫鱼肠道黏膜的蛋白水解活性降低，而淀粉水解活性相比对照组则升高。文中讨论了磁场对鱼类消化水解酶活性的可能影响。
