In the review, contemporary data on the influence of natural and artificial magnetic fields on fish behavior are considered. In this regard, elasmobranchs and teleosts appear to be studied most exhaustively. Elasmobranchs and some teleosts are able to perceive magnetic fields via electroreceptors. A number of teleosts can sense magnetic fields via sensory cells containing crystals of biogenic magnetite. Laboratory experiments and field observations indicate the influence of magnetic fields on fish locomotor activity and spatial distribution. The geomagnetic field can be used by fish for navigation. Besides, artificial magnetic fields and natural fluctuations of the geomagnetic field can affect fish embryos leading to alterations in their development. It is suggested that, afterwards, these alterations can have an effect on fish behavior.
期刊介绍:
Публикуются статьи по теоретическим вопросам биологии, представляющие интерес для биологов любой специальности (вопросы эволюции, экологии, общей таксономии, общей цитологии, генетики, проблемы механизмов приспособления живых организмов к условиям существования, закономерности развития организмов, бионика и т. д.), основанные на новом оригинальном фактическом материале или же подводящие итоги работы того или иного научного коллектива.
Помимо теоретических статей, помещаются рецензии на новые книги российских и зарубежных биологов, а также информация о международных конгрессах и общероссийских совещаниях по важнейшим проблемам биологии.
