Enchytraeids (e.g. Enchytraeus albidus) should have a length of approximately 1 cm.
Enchytraeider (f.eks. Enchytraeus albidus) bør have en længde på ca. 1 cm.

If other species of Enchytraeus are used, they should be clearly identified and the rationale for the selection of the species should be reported.
Hvis andre arter af Enchytraeus anvendes, skal de identificeres klart, og begrundelsen for valget af art skal anføres i rapporten.

Enchytraeus crypticus (Westheide & Graefe 1992) is a species belonging to the same group as Enchytraeus luxuriosus.
Enchytraeus crypticus (Westheide & Graefe 1992) er en art, der tilhører samme gruppe som Enchytraeus luxuriosus.

Large adult specimens of Enchytraeus albidus are then selected (by using a stereomicroscope) to start a new culture.
Store voksne individer af Enchytraeus albidus udvælges derefter (ved hjælp af stereomikroskop) for at starte en ny bestand.

The ASTM Standard Guide for Conducting Laboratory Soil Toxicity or Bioaccumulation Tests with the Lumbricid Earthworm Eisenia fetida and the Enchytraeid Potworm Enchytraeus albidus (3) provides many essential and useful details for the performance of the present soil bioaccumulation Test Method.
ASTM Standard Guide for Conducting Laboratory Soil Toxicity or Bioaccumulation Tests with the Lumbricid Earthworm Eisenia fetida and the Enchytraeid Potworm Enchytraeus albidus (3) indeholder mange vigtige og nyttige oplysninger om udførelsen af denne testmetode vedrørende bioakkumulering i jord.

Enchytraeids of the species Enchytraeus albidus (as well as other Enchytraeus species) can be bred in large plastic boxes (e.g. 30 × 60 × 10 cm or 20 × 12 × 8 cm which is suitable for culture of worms of small size) filled with a mixture of artificial soil and commercially available, uncontaminated garden soil free of additives.
Enchytraeider af arten Enchytraeus albidus (og andre Enchytraeus-arter) kan avles i store plastikkasser (f.eks. 30 × 60 × 10 cm eller 20 × 12 × 8 cm, som er egnet til dyrkning af små orm) fyldt med en blanding af syntetisk jord og uforurenet havejord fri for additiver, som fås i handelen.

Enchytraeus albidus is one of the biggest (up to 15 mm) species of the annelid oligochaete family Enchytraeidae and it is worldwide distributed e.g. (8).
Enchytraeus albidus er en af de største (op til 15 mm) arter af Enchytraeidae-slægten af Oligochaeter (annelida), og den findes i hele verden, f.eks. (8).

However, it is small (3-12 mm; 7 mm on average (Westheide & Müller 1996), and this makes handling more difficult compared with Enchytraeus albidus. When using this species instead of Enchytraeus albidus, the size of the test vessel can but needs not to be smaller. In addition, it should be considered that this species reproduces very rapidly having a generation time of less than 20 days at 20 ± 2 °C (Achazi et al. 1999) and even quicker at higher temperatures.
Den er dog lille (3-12 mm; 7 mm i gennemsnit (Westheide & Müller 1996), og det gør den vanskeligere at håndtere end Enchytraeus albidus. Hvis denne art bruges i stedet for Enchytraeus albidus, kan testbeholderen være mindre, men det er ikke nødvendigt. Det skal desuden tages i betragtning, at denne art reproduceres meget hurtigt og har en generationstid på mindre end 20 dage ved 20 ± 2 °C (Achazi et al. 1999) og endda hurtigere ved højere temperaturer.

Enchytraeus albidus is found in marine, limnic and terrestrial habitats, mainly in decaying organic matter (seaweed, compost) and rarely in meadows (42).
Enchytraeus albidus findes på marine, limniske og terrestriske levesteder, primært i organiske materialer under nedbrydning (tang og kompost) og sjældent i engområder (42).

It has been demonstrated that Enchytraeus albidus and Eisenia fetida can comply with the validity criteria on reproduction when tested in field soils with lower organic carbon content, e.g. 2,7 % (33), (61), and there is experience that this can also be achieved in artificial soil with 5 % peat.
Det er blevet påvist, at Enchytraeus albidus og Eisenia fetida kan opfylde validitetskriterierne for reproduktion ved test i feltjord med lavere organisk kulstofindhold, f.eks. 2,7 % (33) (61), og erfaringer viser, at dette også kan opnås i syntetisk jord med 5 % tørv.

For many species of terrestrial enchytraeids the individual weight is very low (e.g. 5-10 mg wet weight per individual for Enchytraeus albidus and less for Enchytraeus crypticus or Enchytraeus luxuriosus); in order to perform the weight measurements and chemical analysis, it may be necessary to pool the worms of the replicate test vessels (i.e. all the worms of a replicate vessel will be used for obtaining one analytical tissue result).
For mange arter af terrestriske enchytraeider er den individuelle vægt meget lav (f.eks. 5-10 mg vådvægt pr. individ for Enchytraeus albidus og mindre for Enchytraeus crypticus og Enchytraeus luxuriosus). For at kunne foretage vejningen og den kemiske analyse kan det være nødvendigt at samle ormene fra de replikate testbeholdere (dvs. alle orm i en replikat testbeholder bruges til at opnå et analyseresultat for væv).

The most commonly used species Eisenia fetida or Eisenia andrei (Lumbricidae), or Enchytraeus albidus, Enchytraeus crypticus, or Enchytraeus luxuriosus (Enchytraeidae)) are described in Appendix 5.
De oftest anvendte arter, Eisenia fetida eller Eisenia andrei (Lumbricidae), Enchytraeus albidus, Enchytraeus crypticus eller Enchytraeus luxuriosus (Enchytraeidae), er beskrevet i tillæg 5.
