The potential of artificial hideouts, outfitted with magnets or their imitations (control), to attract spinycheek crayfish Orconectes limosus was studied. The experiments were carried out within 1999-2002 in an 80-hectar natural lake. There were thre

Background. The magnetic field is known to exert its influence on both adult and juvenile fishes, as well as the embryos. The effects are diversified and pertain to, practically all, life aspects of an individual. Another aspect of this issue can be

Summary The effects of magnetic fields generated by ferritic magnets and mounted in entrances to fyke nets were studied in 1999–2002. With respect to all fish species trapped (perch, pike, roach, rudd, bleak, bream, ruffe) except eel, the catch pot

Summary Effects of a constant magnetic field on the selection of swimming direction by trout (Salmo trutta L.) larvae and fry were investigated in an experimental facility consisting of chambers equipped with magnets as well as magnet-free chambers p

Background. Ruffe, Gymnocephalus cernuus is a small fish inhabiting vast areas of Europe, Asia, and also North America. Its substantial geographical dispersal range in different climatic zones, in waters of different parameters indicates that this is

Changes in resistance to mechanical pressure during embryogenesis were studied in the signal crayfish (Pacifastacus leniusculus Dana). A constant increase in egg size (volume and surface area) was observed to take place throughout the embryonic devel

The micro- and ultrastructure of intestinal wall of 29 individuals of Ancistrus multispinnis was examined under the scanning and transmission electron microscopes. The presence of cellular structures, analogous to type I pneumocytes forming the mamma

Studies were undertaken on the relationship between egg size and duration of embryogenesis in four freshwater fish species (Salmo trutta L, Esox lucius L., Gasterosteus aculea tus L., Leucaspius delineatus Heck.). Analyses were carried out in a com

Constant magnetic field of low value slows down the embryonic development of trout (Salmo trutta), rainbow trout (Oncorhynchus mykiss). Hatchlings were longer and heavier, and also more motile than those in the control experiment. Magnetic field indu
