Opis:: The study was designed to determine selected components of chemical composition in the body of earthworms cultivated on organic kitchen waste. It was shown that their biomass can be classified as protein-rich, succulent fodder. Notably, this work also specified the contents of 17 essential amino acids, as well as the profile of fatty acids. It also highlighted selected threats to the natural environment caused by food production and food wastage by man. Because of that, this paper also presents the determinants of earthworm biomass production. The possibilities of consuming alternative invertebrate protein were also discussed.

Opis:: Earthworms can be used in the vermicomposting process. The success of the process depends on many factors, including the choice of the appropriate earthworm species. Eisenia fetida and Dendrobaena veneta are treated as "compost earthworms". They are characterized by a relatively short life cycle, relatively fast growth rate, efficient reproduction and a similar amount of organic matter processed, compared to species found in the natural environment. However, while analyzing their features in more detail, it can be seen that these two species differ. The aim of this study was to compare the selected features of the Eisenia fetida (Sav.) and Dendrobaena veneta (Rosa) earthworm populations in an annual cycle. The mature specimens of E. fetida or D. veneta were put in groups into plastic boxes with soil. Populations were checked regularly by manual sorting of the medium. The earthworms and cocoons were cleaned, counted and weighed individually. Afterwards, the mature individuals were placed in appropriate containers, while the cocoons were separated from the starting populations. The earthworms were fed ad libidum on kitchen wastes every four weeks. The experiment was carried out under constant laboratory conditions for 52 weeks. The analysis of the studied populations confirmed that the tested species of earthworms differ from each other. After 52 weeks of the experiment, the sum of earthworm biomass was higher for D. veneta compared to E. fetida species (18.568 ± 1.867 g and 7.263 ± 1.786 g; p <0.01, respectively). This relationship was confirmed for the average body weight of earthworms (D. veneta: 0.912 ± 0.046 g; E. fetida 0.480 ± 0.006 g; t = 15.95, p <0.01) and cocoons (D. veneta: 0.032 ± 0.003 g, E. fetida 0.014 ± 0.001 g; t = 9.15, p <0.01).

Opis:: Anesthetic drugs have been tested for years on rats, rabbits, dogs, cats and monkeys, which may raise ethical concerns. Researchers do not always pay attention to the possibility of using techniques of anesthesia, analgesia or euthanasia in relation to invertebrate animals. It has previously been shown that earthworms meet the requirements of laboratory animals, and being a good alternative to the studies on vertebrates, may also be used as the first stage of testing anesthetics. The lethal concentrations of procaine and lidocaine for E. fetida and D. veneta were established using modified filter paper contact test. Using a modified method developed for testing anesthetics, mature earthworms (clitellate) of both species were used to check the effectiveness of lidocaine and procaine in safe immobilizing of earthworms. The reactions of earthworms in contact with anesthetics were different. The possibility of using a higher concentration range of procaine and lidocaine for E. fetida than for D. veneta, as E. fetida demonstrated a greater resistance to the stress caused by the action of chemical substances. The response to this stress varied and depended on the concentration used; however, higher concentrations of anesthetics caused rapid body movements and discharge of the coelomic fluid as well as morphological changes observed after 48 hours. Procaine was not effective in immobilizing earthworms, but lidocaine proved effective in reversibly immobilizing both species. For E. fetida, lidocaine in the concentrations of 1.4 and 1.6 at 95 and 90 min, respectively, resulted in a full immobilization of animals, which then survived following 24h and 48h of recovery. For D. veneta, lidocaine in the concentrations 1.3 and 1.4 during 40 min proved effective and safe to use, as all individuals survived following 24h and 48h of recovery.
