[Histonet] Invertebrates in Sediment

[BennettW <@t> pac.dfo-mpo.gc.ca]

Hello Histonetters,

Thanks in advance for spending any time with this query!  I have a
researcher that has collected sediment samples, preserved with NBF, and
wants to stain any invertebrates in the sediment so that they can be
enumerated and identified.  The researcher wants to use rose bengal but
doesn't know at what concentration and neither do I.  Can anyone help?  

Thanks
