Dear Geoff,
I used MS222 successfully in narcotising nephtyids. Recovery from
the anaesthetic is excellent. It also has the advantage from the
point of view of photography of being active at very low
concentrations so there's no powder/refractive index change.
It's nasty stuff though so requires appropriate safety procedures in
handling it.
Can I recommend: Smaldon, G & Lee, E.W. (1979) A synopsis of
methods for the narcotisation of marine invertebrates. Royal
Scottish Museum, Edinburgh. 96pp. ISSN 0307-5036
This is a useful publication that offers a number of suitable
methods for a wide range of inverts.
Happy photographing,
Matt
