As most or all users of this list are undoubtedly aware, chemicals such as
Ludox have been used for years to separate meiofauna from marine and
estuarine sediments. In fact, I found a dozen or so references wherein
Ludox was used to extract nematodes and small crustaceans from forest
soils. I would like to know whether anyone has used Ludox or similar
silicate sols to extract larger, i.e., small macrofauna-sized, worms from
sands and gravel. In an early version of Holme and McIntyre's book on
methods for the study of marine benthos there is also a reference to the
use of trichloroethylene. Has anyone tried that or similar compounds?
Ideas on this subject would be greatly appreciated. I have a small project
where we will be sampling with a grab sampler in sand and gravelly sand
sediment.
Best,
Les.
