We report our first results of attempts to rear four species of eutardigrades inhabiting different substrates, feeding on different kinds of food and characterized by different sexual conditions and modes of reproduction. Attempts were carried out to follow individual terrestrial carnivorous (Macrobiotus richtersi, M. joannae) and limnic herbivorous (Diphascon cf. scoticum; Isohypsibius monoicus) species. Carnivorous leaf litter-dwelling species were reared in small dishes containing agar as substrate and bacteriophagous nematodes as food. Five generations were obtained with the triploid. thelytokous strain of M. richtersi, whereas three generations were obtained with the hermaphrodite species M. joannae, Diphascon cf. scoticum and I. monoicus were reared in small dishes containing algae as food and substrate. Several generations were obtained for both species. Males were never found in D. cf. scoticum and I. monoicus was hermaphroditic. Specimens isolated from hatchings were maintained and reproduced in both species, demonstrating parthenogenesis in the first one and self-fertilization in the latter. Consideration of the problems and on the future applications of tardigrade rearing are discussed.
