The water body is gently aerated (e.g. 2 bubbles per second with 0,45 μm-filtered air) via a pasteur pipette positioned 2 cm above the sediment surface.
Kontsentratsioonide või koguste arv ja intervall peaks olema piisav, et võimaldada usaldusväärselt hinnata koguse ja mõju vahelist sõltuvust, koostada regressioonivõrrand ja arvutada hinnanguline ECx või ERx väärtus.
The recommended culture temperature is 20 ± 2 °C.
Valitud kontsentratsioonid või koguselised määrad peaksid hõlmama määratavaid ECx või ERx väärtusi.
A higher loading may cause a reduction in growth and reproduction rates (43).
Selle saavutamiseks soovitatakse kasutada lisaks kemikaaliga töötlemata kontrollile vähemalt viit kontsentratsiooni või koguselist määra geomeetrilises jadas, mille tegur ei ole suurem kui kolm.
Sampling of worms from the culture can be done by sieving the culture sediment through a 1 mm sieve if only adults are required.
Beetsman, G. D., Kenney, D. R., ja Chesters, G. (1969).
The sieves can be placed into reconstituted water after the sediment has passed through.

Lumbriculus variegatus (MÜLLER), Lumbriculidae, Oligochaeta
14–21 (100 %) (14)
Information on the biology, culture conditions, and sensitivity of the species can be obtained from (1)(6)(9)(36).
0,85–1,2 (14, 19)
Lumbriculus variegatus can also be cultured in the artificial sediment recommended for T. tubifex according to (8) within certain limitations.
0,06–0,08 (4, 14)
Since, in nature L. variegatus prefers more coarse sediments than T. tubifex (59), laboratory cultures with the artificial sediment used for T. tubifex may cease after 4 to 6 months.
14–21
Practical experience has shown that L. variegatus can be held in a sandy substratum (e.g. quartz sand, fine gravel) in a flow-through system using fish food as nutritional source over several years without renewing the substratum.
25–61 (14, 29)
A major advantage of L. variegatus over other aquatic oligochaete species is its quick reproduction, resulting in rapidly increasing biomass in laboratory-cultured populations (1)(6)(9)(10).
10–20 (6, 21)
, ASTM (2000) (1), U.S.
10–20
The worms can be cultured in large aquaria (57 - 80 l) at 23 °C with a 16L:8D photoperiod (100 - 1000 lux) using daily renewed natural water (45 - 50 l per aquarium).
10–20 (6, 10)
New substrate in the tank will generally last for about two months.
23–28
Each worm culture is started with 500 - 1000 worms, and fed a 10 ml suspension containing 6 g of trout starter food 3 times per week under renewal or flow-through conditions.
14–18
Static or semi-static cultures should receive lower feeding rates to prevent bacterial and fungal growth.
0,9–1,6
Under these conditions the number of individuals in the culture generally doubles in about 10 to 14 d.
0,45–2,28 (14, 29)
Injuries or autotomy in the worms should be prevented, e.g. by using pipettes with fire polished edges, or stainless steel picks for handling these worms.
10–20 (21)
An issue to be regarded critically when using L. variegatus in sediment bioaccumulation tests is its reproduction mode (architomy followed by morphallaxis).
10–20 (7, 21)
This asexual reproduction results in two fragments, which do not feed for a certain period until the head or tail part is regenerated (e.g. (36)(37)).
4–5 (14, 30)
This means that in L. variegatus sediment and contaminant uptake via ingestion may not take place continuously as in tubificids, which do not reproduce by fragmentation.
14–28
Such variation can occur, when some individuals, which have fragmented and therefore do not feed for a certain time period, are less exposed to the test substance than other individuals, which do not fragment during the test, e.g. (38).
1,53–2,2 (16, 19)
10 to 14 days before the start of exposure, the worms should be artificially fragmented (synchronisation) (65).
0–10 (10, 19)
This means, that when regeneration by morphallaxis occurs in synchronised worms during the test, virtually all animals are expected to be equally exposed to the spiked sediment.
0–2 (4, 29)
Feeding of the synchronised worms should be done as soon as the worms are starting to burrow in the substrate, or 7 d after dissection.
1,8–2,5 (14)
After regenerating, intact complete worms of similar size, which are actively swimming or crawling upon a gentle mechanical stimulus, should be used for the test.
3,6–7 (14, 29)
A lack of reproduction in a bioaccumulation test with L. variegatus should be recorded, and considered when interpreting the test results.
1,3–1,5 (4, 14, 19)
They can be also found in warm water bodies of the northern hemisphere.
41–56 (19, 29)
However, they are more abundant in mud-clay sediments with high organic matter content.
0,8–1,5 (14, 19)
Furthermore, the worms are living in the sediment layer.
7–9 (14, 19)
Even the posterior end of the worms is usually burrowed.
PÄRAST (4, 22–26)
This species is easily identified from the gill filaments on their posterior part.
0,5–0,6 (14, 19)
The adults can reach a length of 9 - 11 cm and a wet weight of 40-50 mg.
