The cultivation of the nematodes Panagrellus, Turbatrix (Anguillula) and Rhabditis for using in fish feeding

Abstract

Purpose. To analyze professional literature and summarize the information on the cultivation of the representatives of three nematode (Nematoda) genera. To highlight the optimal biotechnology of the cultivation of banana nematode (Panagrellus redivivus), vinegar eelworm (Turbatrix aceti) and rhabditis (Rhabditis). To review the biological characteristics of these species along with the possibilities for their use as food objects in aquaculture. Results. This work contains brief information on the biology and cultivation features of the above-mentioned worms. It presents the most cost-effective and simple mass production biotechnology of the cultivation of banana and vinegar nematodes and rhabditis. It can be used under different conditions due to its simplicity and cost-effectiveness. The data regarding the use of nematodes in feeding fish juveniles in general and ornamental fish culture in particular are presented. The chemical composition and nutritional value of these worms, as well as their behavior in aquariums are described. Practical significance. The summarized information will be useful for researchers who are exploring the ways to optimize fish feeding as well as for aquarists. The presented technology of cultivation of banana and vinegar nematodes and rhabditis can be used by a broad range of stakeholders.
